Technical Field

[0001] This application relates to the field of milling and grinding, and in particular to an equipment for manufacturing ultra-thin cutting discs and a method for measuring wear ratio. Background Technology

[0002] Cutting discs are widely used in various material processing fields (electronic components, optical parts, various semiconductor packaging elements, ceramics, single crystals, etc.) in the electronics and electronic information industries.

[0003] After the cutting disc is processed, it needs to be ground to meet the cutting requirements of relevant materials, thus forming an ultra-thin cutting disc. After the ultra-thin cutting disc processing is completed, the wear ratio needs to be calculated to determine the relevant performance of the ultra-thin cutting disc. In the current technology, grinding is generally done manually, which is time-consuming, labor-intensive, and inefficient, and needs to be improved. Summary of the Invention

[0004] To improve the grinding efficiency of cutting discs, this application provides an ultra-thin cutting disc manufacturing equipment and a method for measuring wear ratio.

A drive mechanism for driving the milling frame to rotate along the support column is provided on the support platform.

[0007] By adopting the above technical solution, when grinding the cutting disc, the cutting disc and grinding wheel are simply installed sequentially on the support table and the milling frame. Then, the milling frame is driven by a drive mechanism to rotate along the support column. During the rotation of the milling frame, the grinding wheel grinds the cutting disc, achieving efficient grinding.

The support column passes through the support column and the support platform in sequence and is rotatably connected to both. The first pulley is disposed on the top of the support column. The drive motor is disposed on the support platform. The second pulley is disposed on the drive motor. The drive belt is sleeved on the first pulley and the second pulley.

[0018] Optionally, the workbench is provided with an auxiliary sleeve fitted onto the column, and the top of the auxiliary sleeve is provided with a support spring fitted onto the column. The support spring is used to drive the support platform to slide upward, and the support spring is used to counteract the gravity of the support platform.

[0019] By adopting the above technical solution and setting support springs, the weight of the support plate is offset, effectively avoiding machine collisions during milling and grinding, and ensuring the uniformity of the cutting disc grinding process.
