specific Embodiment approach 1

[0034] Specific embodiment 1: a method for finely dressing a bronze diamond grinding wheel disc with a full runout of an end surface better than 2 μm, the steps of the method are as follows:

[0035] Step 1: Coarse grinding of the surface of the bronze diamond grinding wheel; on the flat grinding machine, the bottom surface of the bronze diamond grinding wheel is positioned, and the ceramic or resin diamond grinding wheel is used to grind the top surface of the bronze diamond grinding wheel. The cutting depth is set to 10-15 μm, and the grinding can be stopped until the surface of the bronze diamond grinding wheel is ground flat, such as figure 1 shown;

[0036] Step 2: Preliminary dynamic balancing of the bronze diamond grinding wheel; install the bronze diamond grinding wheel on the figure 2 shown in the special jig, and then mount it on the image 3 The mass eccentricity and eccentric position of the bronze diamond grinding wheel disc are detected on the dynamic balancing ...

specific Embodiment approach 2

[0048] Specific embodiment 2: This embodiment is a further description of specific embodiment 1. In the step 3, use the optical monitoring system that comes with the diamond tool grinder to observe the single-point trimming pen tip of the large-grain natural diamond before trimming. and adjust the position of the pendulum axis to ensure that the sharp part of the diamond particles on the head of the single-point dressing pen with an average particle size of 1mm irregular natural diamond particles is welded to the head to participate in the trimming. After each trimming for 30 minutes, the laser displacement sensor is installed on the On-site inspection of the dressing accuracy of the bronze diamond grinding wheel surface on the diamond tool grinder, if the total runout value of the end face of the bronze diamond grinding wheel is less than 5 μm, then proceed to step 4, otherwise repeat step 3 to reach the full runout value of the end face of the bronze diamond grinding wheel up...

specific Embodiment approach 3

[0049] Specific implementation mode three: this implementation mode is a further description of specific implementation mode one or two, and the specific steps of the described step four are as follows:

[0050] Bronze diamond wheel disc from Figure 4 Remove the grinder spindle shown and install the bronze diamond disc on the image 3 Detect the mass eccentricity and eccentric position of the bronze diamond grinding wheel disc on the dynamic balancing machine shown, mark the position indicated by the dynamic balancing machine on the bottom of the bronze diamond grinding wheel disc, remove the bronze diamond grinding wheel disc, according to the detected eccentricity, bronze diamond grinding disc The material density on the bottom surface of the grinding wheel disc and the diameter of the drill bit are used to calculate the required drilling depth at the mark, and then the drilling operation is carried out on the drilling machine. If the mass eccentricity of the diamond grind...

Abstract

The invention relates to a precise dressing method for a bronze diamond abrasive disc with end surface total run-out superior to 2[mu]m and belongs to the technical field of manufacturing of high precision diamond cutters. The method provided by the invention comprises the primary steps of: rough grinding of a surface of the bronze diamond abrasive disc, initial dynamic balancing of the bronze diamond abrasive disc, rough dressing of the surface of the bronze diamond abrasive disc, precise dynamic balancing of the bronze diamond abrasive disc and fine dressing of the surface of the bronze diamond abrasive disc. By means of the bronze diamond abrasive disc fine dressing process, the rules of the influence of fine dressing process parameters such as the spindle rotating speed, the dressing pressure, single feed dressing depth and spindle reciprocating frequency on end surface total run-out of the bronze diamond abrasive disc is analyzed in detail, and the fine dressing process parameters are optimized. The surface of the bronze diamond abrasive disc obtained by means of the method is very high in precision, and the end surface total run-out is superior to 2[mu]m, so that development on precise dressing technology of the bronze diamond abrasive disc is promoted.

Description

technical field [0001] The invention relates to a method for precisely trimming a bronze diamond grinding wheel disc, and belongs to the technical field of high-precision diamond cutter manufacturing. Background technique [0002] With the development of cutting-edge technologies such as nuclear energy, lasers, and astronomical telescopes, the role of ultra-precision processing technology is becoming more and more important, and it has become a symbol of the highest level of a country's manufacturing industry. In ultra-precision machining, precision high-performance machine tools and an extremely stable machining environment are essential, and high-precision tools are also crucial. At present, the traditional mechanical sharpening method is still the main method for manufacturing high-precision diamond tools. In the mechanical sharpening process of diamond tools, the grinding wheel directly interacts with the diamond tools. The surface roughness of the high-speed rotating ...
