Embodiment 1

[0019] The Archimedes spiral grinding disc of the present embodiment is characterized in that the upper surface of the grinding disc is provided with an Archimedes spiral 1, and the width of the spiral groove in the Archimedes spiral is 4 mm, and the depth is 5 mm, so that the grinding disc During the working process, the force-bearing area and contact surface with the workpiece are in an ideal state. The center of the upper surface of the grinding disc is also equipped with an abrasive and impurity collection tank 4 to collect abrasives and impurities in time to prevent abrasives and impurities from being excluded from causing damage to the surface of the workpiece. Scratches increase, affecting the precision of finished products. The collection tank has an inner diameter of 160.0mm and a depth of 30.0mm.

[0020] There is a positioning hole 2 on the back of the grinding disc. The location and size of the positioning hole match the size of the boss on the grinding machine. Th...

Embodiment 2

[0042] The Archimedes spiral grinding disc of the present embodiment is characterized in that the upper surface of the grinding disc is provided with the spiral groove in the Archimedes spiral.

Abstract

The invention relates to an Archimedes spiral stripe lapping disc for ultra-precision lapping processing, and belongs to the technical field of lapping disc structures. The Archimedes spiral stripe lapping disc for the ultra-precision lapping processing is characterized in that an Archimedes spiral stripe is arranged on the upper surface of the lapping disc, a positioning hole is formed in the reverse side of the lapping disc, a through hole is formed in the center of the lapping disc, a thread id formed on the inner wall of the through hole, the position of the through hole is consistent with the position of a through hole in a lapping machine, a fixing screw fixes the lapping disc and the lapping machine together through the through holes. The Archimedes spiral stripe lapping disc for the ultra-precision lapping processing can perform even and continuous scraping lapping on surfaces of work pieces based on Archimedes spiral pattern grains under the condition that linear speeds are equal, and thereby improves qualified rate of the work pieces, can simultaneously process a batch of the work pieces in the lapping processing, achieves good surface roughness for the work pieces, and is high in work efficiency, and low in requirement for accuracy of the lapping machine.

Description

technical field [0001] The invention relates to an Archimedes spiral pattern grinding disc used for ultra-precision grinding processing, and belongs to the technical field of grinding disc structures. Background technique [0002] With the continuous development of technology, there are more and more applications of precision machinery. In the field of precision machinery, the requirements for processing accuracy and surface quality are getting higher and higher. Grinding is an important processing method for precision machining. The surface roughness and The integrity of the surface is one of the key factors affecting the performance of the workpiece. Any tiny particles will damage the texture and roughness of the surface, cause the workpiece to be reworked, and affect the processing efficiency and product stability. The surface of the traditional grinding disc has several forms such as smooth surface, fishnet-like texture, micro-groove and concave-convex point, etc. Most o...
