Abstract
Description
Technical Field
[0001] This invention relates to the field of grinding machine technology, specifically to a mineral casting bed for a grinding machine, its mold assembly, and a method for implementing it. Background Technology
[0002] As the core basic component of a machine tool, the performance of the machine bed directly determines the accuracy, stability, and lifespan of the entire machine. In ultra-precision machining fields such as grinding machines, extreme requirements are placed on the vibration damping, thermal stability, and dynamic rigidity of the machine bed.
[0003] Currently, the mainstream machine tool bed materials are cast iron and natural marble. Although cast iron beds have good mechanical strength and machinability, their damping performance (vibration reduction) is insufficient, and they are prone to thermal deformation due to frictional heat and changes in ambient temperature under high loads and long-term operation, leading to a deterioration in machine tool accuracy. Natural marble beds have excellent dimensional stability and a certain degree of vibration reduction, but their material is brittle and has poor impact resistance. More importantly, they are difficult to machine into complex internal structures, cannot integrate cooling channels and sensing elements, and have limited functionality.
[0004] Mineral castings (or resin concrete), as an emerging material, are made by bonding specially graded mineral aggregates with epoxy resin. Due to their high damping characteristics (6-10 times that of cast iron), low thermal conductivity, and excellent thermal stability, they have begun to be used in the field of high-end machine tools. However, most existing mineral casting machine beds still play the role of passive vibration reduction and support "structural components". Their intelligent potential has not been explored. They cannot sense their own state in real time (such as temperature field and vibration spectrum), and they do not have the ability to actively manage thermal and optimize dynamic performance according to working conditions.
[0005] In actual grinding, the movement of the guide rail pair, the rotation of the spindle, and the grinding itself generate a large amount of heat. If this heat cannot be effectively dissipated, it will cause local temperature rise and thermal deformation of the machine bed, directly damaging the machining accuracy. At the same time, the unavoidable vibrations during the machining process, especially resonance and chatter, will significantly reduce the surface quality of the workpiece. Existing technologies lack effective solutions that combine the advantages of the machine bed material with state perception and active control, making it difficult to further improve the machine tool's accuracy retention and intelligence level.
[0006] Therefore, there is an urgent need in this field for innovative bed solutions that not only inherit the material advantages of mineral castings, but also integrate sensing and temperature control functions, achieving a leap from "passive support" to "active intelligence". Summary of the Invention
[0007] The purpose of this invention is to overcome the shortcomings of the prior art and provide a mineral casting bed and its mold assembly and implementation method for use in grinding machines. The bed is designed to combine the inherent performance advantages of mineral castings with built-in sensing and cooling systems to achieve real-time status monitoring, active suppression of thermal deformation and adaptive vibration control, thereby significantly improving the machining accuracy, stability and intelligence level of the grinding machine.
[0008] The present invention proposes a mineral casting bed for a grinding machine, comprising: a bed body made of mineral casting material with epoxy resin as a binder; a guide rail assembly mounted on the surface of the bed body; a cooling assembly including a cooling water pipe embedded in the bed body, the two ends of the cooling water pipe being connected to an inlet and an outlet respectively provided on the bed body; and a sensor assembly including a temperature sensor and a vibration sensor embedded in the bed body.
[0009] Addressing the shortcomings of traditional grinding machine beds, such as poor vibration damping of cast iron and limited functionality of marble, this bed achieves a breakthrough through "mineral casting + functional integration." The main body of the bed is made of epoxy resin-bonded mineral aggregate, possessing both high damping (superior vibration damping compared to cast iron) and low thermal expansion characteristics, providing a stable foundation for the grinding machine. The guide rail assembly is mounted on the bed surface to ensure motion accuracy. Pre-embedded cooling water pipes enable active temperature control, and sensor components monitor the status in real time, replacing the traditional bed's "passive support" positioning. This upgrade from structural components to intelligent components adapts to the stringent requirements of ultra-precision grinding for thermal and dynamic stability. At the same time, the castability of the mineral casting ensures the integrated integration of functional components, avoiding later installation errors and improving reliability.
[0010] As a further optimization of the present invention, the cooling water pipe is arranged through the area below the guide rail assembly.
[0011] The cooling water pipes are arranged below the guide rails, which can directly cool the frictional heat generated by the movement of the guide rails, suppressing temperature rise at the source of heat and avoiding accuracy deviations caused by thermal expansion of the guide rails. The design of the water pipe path takes into account the uniformity of the overall temperature field of the machine bed, avoiding local overheating or undercooling and the formation of thermal stress, thus ensuring the geometric stability of the machine bed. At the same time, the pre-embedded arrangement does not occupy the surface space of the machine bed, does not affect the installation of the guide rails and the operation of moving parts, and is compatible with the compact structural layout of the grinding machine, ensuring that the cooling function and mechanical performance do not interfere with each other.
[0012] As a further optimization of the present invention, the surface of the bed body is provided with an inclined angle toward a processing coolant outlet;
[0013] The inclined design of the bed surface guides the grinding coolant to the drain port, preventing liquid residue on the bed surface and avoiding localized temperature rise (affecting thermal stability) and material corrosion (extending bed life) caused by liquid accumulation. The inclined structure eliminates the need for additional power to drive the drain, simplifying system design and reducing energy consumption. The drain port collects coolant centrally, facilitating subsequent filtration and recycling, meeting the requirements of green manufacturing. At the same time, it keeps the bed surface clean, reducing processing pollution caused by liquid accumulation and improving grinding accuracy and workpiece surface quality.
[0014] As a further optimization of the present invention, the temperature sensor is disposed in the area above the cooling water pipe and / or the mounting area of the guide rail assembly;
[0015] Temperature sensors are positioned above the cooling water pipes and in the guide rail mounting area. They can sensitively capture the impact of cooling effect and guide rail friction heat on the bed temperature, providing accurate feedback for the temperature control system. The sensors above the cooling water pipes monitor the heat exchange efficiency of the coolant to ensure timely temperature control adjustment. The sensors in the guide rail mounting area directly sense the temperature around key moving parts, avoiding the impact of guide rail thermal deformation on accuracy. The multi-area arrangement forms a temperature field monitoring network, covering the core area of the bed, ensuring no blind spots in temperature control and adapting to the thermal stability requirements of the grinding machine under all operating conditions.
[0016] As a further optimization of the present invention, the vibration sensor is disposed in the joint area between the bed body and the guide rail assembly;
[0017] Vibration sensors are installed in the area where the bed and guide rail meet. This area is a critical path for vibration transmission and can accurately capture forced vibration, resonance, and chatter signals during the grinding process, avoiding monitoring distortion caused by signal attenuation. Vibration in the meeting area directly affects the motion accuracy of the guide rail and the machining quality of the workpiece. The sensor can report abnormal vibrations at this location in the first instance, providing timely data support for vibration control. At the same time, the sensor is embedded internally to avoid external interference and mechanical damage, improving monitoring stability and service life, and adapting to the long-term high-frequency operation requirements of the grinding machine.
[0018] As a further optimization of the present invention, the temperature sensor is a platinum resistance temperature sensor, and the vibration sensor is an inertial sensor.
[0019] Platinum resistance temperature sensors offer high precision and long-term stability, accurately monitoring bed temperature changes (with minimal error) and meeting the high temperature control accuracy requirements of grinding machines. Inertial sensors can simultaneously acquire acceleration and angular velocity signals, comprehensively capturing three-dimensional vibrations. They can not only identify vibration amplitude but also analyze vibration frequency characteristics, providing multi-dimensional data for resonance and chatter detection. Both types of sensors have excellent environmental adaptability (temperature resistance and interference resistance), making them suitable for long-term operation embedded inside the bed, ensuring reliable monitoring data and laying the foundation for intelligent control.
[0020] A mold assembly for manufacturing the bed of the aforementioned mineral casting includes: a mold cavity whose inner cavity shape matches the outer shape of the bed body; and embedded tooling, disposed in the mold cavity, for accurately positioning and fixing the guide rail assembly, cooling water pipe, temperature sensor, and vibration sensor before casting.
[0021] The mold cavity determines the geometric contour of the bed, ensuring that the bed shape is consistent with the design and providing a precise foundation for subsequent processing and assembly. The pre-embedded tooling, through structures such as clamps and positioning pins, suspends and fixes the guide rail pre-installed parts, cooling water pipes and sensors in the designed position before casting, avoiding component displacement during casting and ensuring the integration accuracy of functional components. The tooling is adapted to the flow characteristics of mineral castings, does not hinder the filling of castings, ensures that there are no voids inside the bed and that the pre-embedded parts are tightly wrapped, realizing the integrated molding of function and structure, reducing the difficulty and error of later assembly, and adapting to the needs of mass production.
[0022] A method for implementing the above-mentioned mineral casting machine bed includes a temperature control method and a vibration control method. The temperature control method includes: monitoring the machine bed temperature in real time using the temperature sensor and comparing it with a set value; and controlling the parameters of the coolant flowing through the cooling water pipe to perform closed-loop regulation of the machine bed temperature. The vibration control method includes: acquiring vibration signals in real time using the vibration sensor; identifying the vibration state after signal processing; and automatically adjusting the spindle speed or feed parameters of the machine tool to suppress vibration when the vibration exceeds a threshold.
[0023] The temperature control method uses closed-loop regulation to compare and monitor the temperature with the set value in real time, and adjusts the coolant parameters (flow rate and temperature) to stabilize the bed temperature within the target range and suppress thermal deformation. The vibration control method identifies abnormal vibrations (such as resonance and chatter) through signal processing and automatically adjusts the machining parameters (spindle speed and feed rate) to avoid vibration sources from the source and ensure machining stability. The combination of the two methods achieves "heat-vibration" coordinated control, which not only solves the accuracy degradation caused by temperature, but also eliminates the impact of vibration on surface quality. It is suitable for intelligent operation of grinding machines under all working conditions, reduces manual intervention, and improves machining consistency and efficiency.
[0024] As a further optimization of the present invention, in the vibration control method, the collected vibration signal is subjected to fast Fourier transform analysis to extract vibration spectrum features.
[0025] Fast Fourier Transform converts vibration time-domain signals into frequency-domain spectra, which can clearly extract vibration frequency, amplitude and other features, accurately identify resonance frequency (strong vibration caused by overlap with the system's natural frequency) and flutter frequency (characteristic frequency of self-excited vibration), avoiding the limitations of judging vibration type only by amplitude. Spectrum analysis provides a basis for vibration source location and parameter adjustment. For example, after identifying the resonance frequency, the spindle speed can be adjusted to avoid the frequency, improving the accuracy of vibration control and adapting to the vibration optimization needs under complex machining conditions of grinding machines.
[0026] As a further optimization of the present invention, the temperature control method and the vibration control method work together to jointly ensure the thermal stability and dynamic stability of the grinding machine during the processing.
[0027] Temperature control stabilizes the bed temperature field, preventing thermal deformation from altering the bed's natural frequency and providing a stable dynamic basis for vibration control. Vibration control suppresses vibration, reduces additional frictional heat (such as abnormal friction of the guide rails caused by vibration), and lowers the temperature control load. The two work together in a positive cycle, enabling the bed to simultaneously resist thermal deformation and vibration. Regardless of changes in grinding load (such as switching between rough and fine grinding) or fluctuations in ambient temperature, it can maintain a high-precision machining state, meeting the long-term precision requirements of grinding machines. At the same time, it provides data support for machine tool health monitoring (such as predicting faults through temperature and vibration data), improving the level of intelligent management.
[0028] The mineral casting bed for grinding machines, its mold assembly, and the implementation method proposed in this invention have the following beneficial effects:
[0029] (i) By pre-embedded cooling water pipes and temperature sensors inside the machine bed, a closed-loop temperature control system is constructed. The system can sense the temperature rise in key areas (such as under the guide rail) in real time and automatically adjust the coolant flow and temperature to achieve active and precise control of the machine bed temperature, which fundamentally suppresses thermal deformation and provides a guarantee for maintaining high machining accuracy in the long term.
[0030] (ii) The built-in vibration sensor can capture the vibration spectrum characteristics of the machine tool in real time. When harmful resonance or chatter is identified, the control system can automatically adjust parameters such as spindle speed or feed rate to avoid vibration peaks and effectively suppress the generation of vibration. This enables the machine tool to obtain a stable processing state under a wide range of process parameters, which significantly improves the surface quality and shape accuracy of the workpiece.
[0031] (iii) By utilizing the good fluidity and embeddability of mineral casting materials during casting, functional components such as sensing and cooling are integrated into the machine bed in one go during the manufacturing stage. This integrated design avoids errors and inconveniences in later installation, has a compact structure and high reliability, and at the same time maintains the excellent structural damping and thermal stability of the mineral casting itself.
[0032] (iv) The continuously collected temperature and vibration data are not only used for real-time control, but also provide data support for machine tool health status assessment and predictive maintenance. By analyzing historical data, potential faults can be predicted, realizing the transformation from "post-event maintenance" to "pre-event warning", which improves the intelligence level of equipment management and operational reliability.
[0033] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0044] Please see Figures 1-7 The core of the mineral casting bed of the present invention lies in the integrated integration of functional components (sensing, cooling) and high-performance structural materials (mineral casting) during the manufacturing stage, as detailed below:
[0045] The main body of the bed 1 is an integral component manufactured by casting process using mineral casting (or resin concrete) material. Its material formula uses epoxy resin as a binder and is mixed with mineral fillers of specific gradation (such as granite fragments, quartz sand, etc.). This material combination gives the bed extremely high damping performance (vibration reduction is 6-10 times that of cast iron) and excellent thermal stability (low coefficient of thermal expansion, low thermal conductivity), providing an ideal basic platform for high-precision grinding.
[0046] The following key functional modules are pre-installed inside the main body 1 of the bed:
[0047] Cooling assembly: includes a meandering cooling water pipe 7, with its two ends connected to an inlet 4 and an outlet 3 respectively, to form a closed liquid cooling circuit;
[0048] Sensor assembly 5 includes a temperature sensor 51 for monitoring temperature and a vibration sensor 52 for monitoring mechanical vibration, which are strategically placed in key locations on the bed.
[0049] Guide rail assembly 2: Through precision machining and installation, it is fixed to the upper surface of the bed body 1 and is used to support and guide the moving parts of the grinding machine such as the slide and worktable.
[0050] Processing coolant outlet 8: The bed worktable is designed with a specific tilt angle, so that the coolant used in the grinding process can flow naturally to and collect in this outlet, and be quickly discharged from the machine tool to avoid local temperature rise and pollution caused by liquid accumulation;
[0051] Interfaces: Inlet 4 and outlet 3 are used to connect to the external circulating cooling system, and sensor assembly 5 is connected to the machine tool CNC system or a dedicated intelligent control unit via pre-embedded cables.
[0052] Based on the above structure, Embodiment 1 is provided, as follows:
[0053] The arrangement of the cooling water pipe 7 is carefully designed. Its core principle is to prioritize cooling heat sources and key stress-bearing parts. Its main pipe section is arranged in the area directly below the guide rail assembly 2. This is because the guide rail generates significant frictional heat during high-speed reciprocating motion and is one of the main heat sources on the bed. Directly cooling this area can most effectively suppress the loss of geometric accuracy caused by the thermal expansion of the guide rail.
[0054] The cooling water pipes 7 are arranged with varying heights inside the bed to ensure that the coolant flows with gravity assistance, avoiding cavitation or dead zones and ensuring heat exchange efficiency.
[0055] By adjusting the temperature and flow rate of the coolant flowing into the bed through an external cooling system, active control of the bed temperature can be achieved.
[0056] Based on the above structure, a second embodiment is provided, as follows:
[0057] Temperature sensor 51: Platinum resistance temperature sensor, such as PT100, is preferred because of its high accuracy and long-term stability. They are embedded in the area above the cooling water pipe 7 and near the guide rail mounting base. These locations can most sensitively sense the influence of processing heat and frictional heat on the bed temperature field, providing timely feedback signals for the temperature control system.
[0058] Vibration sensor 52: Preferably an inertial sensor, such as MPU6050, which can simultaneously measure triaxial acceleration and triaxial angular velocity. They are installed in the joint area between the bed body 1 and the guide rail assembly 2. This area is the critical path for vibration transmission and can most accurately capture the forced vibration, self-excited vibration and system resonance signals generated during grinding.
[0059] To achieve the one-piece molding of the aforementioned complex structure, Embodiment 3 is provided, the key being a dedicated mold assembly 6, which specifically includes:
[0060] Mold cavity 61: Its inner cavity shape is completely consistent with the final design shape of the bed body 1, which determines the geometric contour of the bed;
[0061] Mold frame 62: A robust rigid frame used to fix and support the mold cavity 61, ensuring that the cavity does not deform or shift during the pouring and curing process;
[0062] Embedded fixture 63: This is the core fixture for realizing functional integration. It consists of a series of precisely positioned clamps, brackets and positioning pins. Before pouring the mineral casting mixture into the mold cavity 61, it is used to fix the pre-installed parts of the guide rail assembly, cooling water pipe 7, temperature sensor 51 and vibration sensor 52, ensuring that they are suspended and fixed in the designed position.
[0063] The specific manufacturing process is as follows:
[0064] Step 1: Clean the mold cavity 61, and then use the pre-embedded tooling 63 to accurately install all the functional components that need to be pre-embedded into place;
[0065] Step 2: Mix the epoxy resin and mineral filler thoroughly according to the formula, and then pour the mixture into the mold cavity 61. The good flow properties of the mineral casting ensure that it is fully filled and covers all the embedded parts.
[0066] Step 3: Allow the epoxy resin to cure fully in a controlled environment. After curing, remove the mold frame 62 and mold cavity 61 to obtain a complete bed blank integrating all functional components.
[0067] Step 4: Perform precision machining on the upper surface of the bed to ensure the required flatness and levelness, and finally install external parts such as guide rail assembly 2.
[0068] Based on the above structure, Embodiment 4 is provided, in which the "intelligence" of the bed is reflected in its integrated temperature and vibration control methods, as detailed below:
[0069] like Figure 4 The temperature control method shown is a typical closed-loop control system, and its workflow is as follows:
[0070] Signal acquisition: Temperature sensor 51 monitors the temperature T_meas at key points on the bed in real time;
[0071] Deviation calculation: The measured temperature T_meas is compared with the target temperature T_set set by the system to obtain the temperature deviation ΔT;
[0072] Control decision: The controller calculates the control signal based on the magnitude and trend of the deviation ΔT;
[0073] Execution regulation: The control signal drives the external cooling system, such as a proportional valve, variable frequency water pump, or chiller, to regulate the flow rate or temperature of the coolant flowing into the cooling water pipe 7;
[0074] Feedback closed loop: The adjusted cooling effect acts on the bed, changing its temperature T_meas. The new temperature signal is collected again, and so on, forming a closed loop to stabilize the bed temperature within the set range and effectively compensate for thermal deformation.
[0075] like Figure 5 The vibration control method flowchart shown is for an adaptive control system, and its workflow is as follows:
[0076] Signal acquisition and processing: Vibration sensor 52 acquires the original acceleration a(t) and angular velocity ω(t) signals in real time. The signal processing module filters these signals to remove noise and performs Fast Fourier Transform (FFT) to convert the time domain signal into a frequency domain signal to obtain the vibration spectrum.
[0077] Feature recognition and judgment: The feature recognition module analyzes the vibration spectrum and identifies the main vibration frequency components and their amplitudes. When the amplitude of a specific frequency (especially the resonance peak close to the system's natural frequency or the frequency that characterizes flutter) exceeds the preset safety threshold, the system determines it to be an abnormal or harmful vibration state.
[0078] Control Decision and Execution: Based on the identified vibration characteristics, the control algorithm module calculates the optimized machining parameter adjustment amount, such as the correction amount ΔS of the spindle speed or the correction amount ΔF of the feed rate. These instructions are sent to the CNC unit of the grinding system.
[0079] Adaptive adjustment and closed loop: The CNC unit performs parameter adjustment to change the state of the grinding process, thereby suppressing or avoiding vibration from the source. The adjusted vibration state is captured by the sensor again, forming a closed loop control, continuously optimizing the machining process, and ensuring stability and surface quality.
[0080] In summary, the intelligent mineral casting bed of this invention does not operate in isolation with temperature control and vibration control, but rather works in synergy. A stable temperature field helps maintain the geometric accuracy and dynamic characteristics of the machine tool, providing a better foundation for vibration control. Meanwhile, a stable vibration state reduces additional frictional heat generation. Together, they form the cornerstone for ensuring the high precision, high stability, and intelligence of the grinding machine. This invention successfully integrates high-performance structural materials, built-in functional components, specialized manufacturing processes, and intelligent control algorithms, creating an innovative machine tool bed solution that moves from "passive support" to "active intelligence."

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
