AI Technical Summary

Problems solved by technology

Now in the plane optics industry, the technical difficulty of the glass ring window lies in the processing of the concentricity of the product. The precise range of the concentricity of the glass ring window in the industry is about 0.1mm-0.2mm, and the processing yield of the product exceeds 80%. The cost will be high, and the concentricity of the existing ring windows has not met the customer's requirements

Embodiment 1

[0015] Inspect the incoming material to confirm whether the glass 1 is qualified; use the grinding head of the CNC equipment to grind and cut out a circle with an inner diameter of 3.3mm on the glass 1 at high speed, and the glass 1 has a round hole 2 at the center of the circle; The circular hole 2 is positioned, and the outer edge of the glass 1 is processed by a profiling edging machine to obtain a glass disc 3 with an outer diameter of 12.5 mm; the surface of the glass disc 3 is ground and polished to obtain a circular viewing window 4 ; After the ring window 4 is detected, it is packed and shipped.

Embodiment 2

[0017] Inspect the incoming material to confirm whether the glass 1 is qualified; use the grinding head of the numerical control equipment to grind and cut out a circle with an inner diameter of 14.2mm on the glass 1 at high speed, and the glass 1 has a round hole 2 at the center of the circle; The circular hole 2 is positioned, and the outer edge of the glass 1 is processed using a profiling edger to obtain a glass disc 3 with an outer diameter of 25 mm; the surface of the glass disc 3 is ground and polished to obtain a circular window 4; After the ring window 4 is detected, it is packaged and shipped.

Embodiment 3

[0019] Inspect the incoming materials to confirm whether the glass 1 is qualified; use the grinding head of the numerical control equipment to grind and cut out a circle with an inner diameter of 41mm on the glass 1 at high speed, and there is a round hole 2 on the glass 1, which is at the center of the circle; The round hole 2 is positioned, and the outer edge of the glass 1 is processed by a profiling edger to obtain a glass disc 3 with an outer diameter of 62 mm; the surface of the glass disc 3 is ground and polished to obtain a circular window 4; After the ring window 4 is tested, it is packaged and shipped.

[0020] The method for processing circular windows disclosed by the present invention saves raw material costs, reduces energy consumption, and reduces production costs. The concentricity of the prepared glass circular windows is increased from the original 0.1mm-0.2mm to 0.04mm, The good product rate has increased from 80% to over 97%.

Abstract

The invention discloses a method for machining a circle window tablet, which comprises the following steps of: cutting out a circle with a certain inside diameter on a glass by using a grinding head of numeric control equipment; positioning a round hole on the glass at a circle center position by using a core-taking jig; machining an outer edge of the glass by a profiling edge grinding machine to obtain a glass wafer with a certain outside diameter; grinding and polishing the surface of the glass wafer to prepare the circle window tablet; detecting the circle window tablet; and packaging and shipping. According to the method for machining the circle window tablet, the circle window tablet prepared by the method is more accurate in concentricity, high in yield of the product and low in production cost.

Description

technical field [0001] The invention relates to a processing method of a circular window, in particular to a processing method of a high-precision glass circular window. Background technique [0002] Ring windows are widely used in industries such as automobiles, cameras, and measuring instruments. With the improvement of people's production and living standards, customers have higher and higher requirements for the parameters of ring windows, especially in the automotive industry. Ring windows are used in automotive parts such as interiors, buttons, and electronic equipment. At the same time, the strict requirements of the automotive industry also require the high precision of ring windows, and glass ring windows are environmentally friendly, practical, and Aspects such as appearance are all greatly surpassed previous rubber ring window. Now in the plane optics industry, the technical difficulty of the glass ring window lies in the processing of the concentricity of the pr...
