AI Technical Summary

Benefits of technology

The invention relates an equipment used during manufacturing processes that uses abrasive materials such as glass or plastic material to make optical components like lenses. These tools require precise control over their surface quality before they work properly with them. To ensure proper performance it requires accurate positioning of these parts relative to each other accurately without any misalignment issues. This integration makes movement easier because both gratings have support means attached thereto.

Problems solved by technology

This patented technical problem addressed during this patents text describes how to improve the quality control process used to manufacture optical elements like prisms while minimizing any damage done to their edges.

Embodiment Construction

[0077] The device for grinding a prismatic member ("the device") in the embodiment can grind the four side surfaces and edges extending in the vertical direction of a member having a shape whose section is 125-155 mm in length on each side square with a length of 200 mm.

[0078] For the following examples, the prismatic members processed with this device were produced by cutting an ingot made of glass longitudinally and transversely with a band saw.

[0079] as table 1 and Figure 14 As shown, after cutting the ingot with a band saw to form a prismatic member, the maximum roughness Ry of the side surface of the member is Ry=9-11 μm, and the depth of microcracks on the surface of the member is 70-80 μm.

[0080] The device of the embodiment of the present invention will be explained below in conjunction with the accompanying drawings. The device includes a first grinding device and a second grinding device. They all come with a brush tool. The brush tool has brushes made of re

Abstract

An object of the invention is to provide a device for polishing a prismatic member (W) which can improve roughness of the member surface, reduce a failure rate in generating a wafer by using he member by minimizing the depth of micro cracks of the member surface. The device (M) has a carrying line (1) composed of a carry-in line (2) for carrying an unpolished prismatic member (W) and a carry-out line (3) for carrying out a polished prismatic member (W) and a polishing line (10) having a pair of plane polishing devices (11) and a pair of corner polishing devices (12) disposed at positions respectively opposed to each other. Each plane polishing device (11) has a rough polishing device (11A), a first fine polishing device (11B) and a second fine polishing device (11C) which are arranged successively. The corner polishing device (12) includes a rough polishing device (12A) and a fine polishing device (12B) which are arranged successively. The member (W) is arranged on a traveling device (5) which travels between the pair of the plane polishing devices (11) and the pair of the corner polishing devices (12), and then the member is polished.
