Problems solved by technology

[0006] The purpose of the present invention is to solve the problems that the existing gradient grinding disc only has a single modulus of elasticity, the function of the grinding disc is single, the repair of the grinding disc is cumbersome, the replacement is inconvenient, and the problem that it cannot be adapted to a variety of different workpieces for grinding and polishing is provided. A combined grinding and polishing plate for columnar and rod-shaped materials with a gradient function is developed, which can realize the gradient distribution on the surface of the grinding and polishing plate and up and down, which is convenient for the processing and use of different workpieces; realize the high processing efficiency of the grinding and polishing plate, wide application range, and realize precision machining A major innovation in the field

Embodiment 1

[0025] For workpieces that need to be processed from rough grinding to fine grinding to fine grinding and then to polishing, four areas with continuously distributed elastic modulus are required. Abrasive rods can be stacked into four-level annular areas, and all abrasive rods in each annular area The elastic modulus is the same, and the elastic modulus of the four-stage annular area is distributed in a gradient manner, which meets the processing requirements from rough grinding to fine grinding to fine grinding and then to polishing. Straight-line feeding can pass through the four-stage annular area in turn, so that the processing from rough grinding to fine grinding to rough polishing and then to fine polishing can be realized on the polishing disc.

[0026] Three layered blocks are arranged on the grinding base, and the grinding base is divided into multiple annular areas, and rapid stratification of the abrasive rods can be realized by closely arranging a plurality of abras...

Embodiment 2

[0028] For workpieces that need to be processed from rough grinding to fine grinding to fine grinding and then to polishing, four areas with continuously distributed elastic moduli are required. Abrasive rods can be stacked into multi-stage fan-shaped areas, and the elastic modulus in each fan-shaped area The amount distribution in the radial direction presents a gradient distribution in line with the processing requirements of the workpiece. The workpiece is rotated while performing linear feed in each fan-shaped area, and can pass through the gradient distribution area of ​​each fan-shaped area in turn. The processing from rough grinding to fine grinding to fine grinding and then to polishing can be realized in any fan-shaped area on the polishing disc; since the abrasive rods are piled up into multi-stage fan-shaped areas, each workpiece can be processed in each fan-shaped area. Therefore, the prepared lapping and polishing disc can be simultaneously adapted to the processin...

Abstract

The invention discloses a combined cylindrical bar grinding and polishing disc with a gradient function. The combined cylindrical bar grinding and polishing disc comprises a grinding base and a series of manufactured thin and long cylindrical abrasive bars with different elasticity moduli. The cylindrical abrasive bars are completely consistent in size and shape and are arranged on the grinding base according to the requirements of machined workpieces so as to form the grinding and polishing disc with the densely distributed abrasive bars. The combined cylindrical bar grinding and polishing disc is simple in structure, convenient to manufacture and high in machining quality and machining efficiency. According to the manufactured grinding and polishing disc, gradient distribution on the surface of the grinding and polishing disc can be achieved, gradient elasticity modulus distribution in the axial direction of the grinding and polishing disc is also achieved, and machining of different workpieces is facilitated.

Description

technical field [0001] The invention relates to the technical field of ultra-precision machining, and more specifically relates to a columnar bar combined grinding and polishing plate with a gradient function. Background technique [0002] The traditional processing method of using a grinding disc or a polishing disc separates the grinding and polishing processes, so that the grinding and polishing disc needs to be replaced when the grinding is transitioned to polishing, and the processing efficiency is difficult to improve. At the same time, the current preparation of grinding discs or polishing discs is made into discs at one time, and the grinding properties of the disc surface are single, so it is difficult to achieve the required surface quality of materials during processing. [0003] Over the past few decades, the research and development of materials has mainly focused on homogeneous materials, that is, whose overall structure and properties do not vary with spatial ...
