Product Overview

Description

Product Description

Quartz glass is glass consisting of silica in amorphous (non-crystalline) form. It differs from traditional glasses in containing no other ingredients, which are typically added to glass to lower the melt temperature. Fused silica, therefore, has high working and melting temperatures. The optical and thermal properties of fused quartz are superior to those of other types of glass due to its purity. For these reasons, it finds use in situations such as semiconductor fabrication and laboratory equipment. It has betterultraviolet transmission than most other glasses, and so is used to make lenses and other optics for the ultraviolet spectrum. Its low coefficient of thermal expansion also makes it a useful material for precision mirror substrates

Product Processing

Mulititool Machining.

The quartz material will be stuck on the board and be absorbed by electromagnet on the workbench. In order to cut the material, the workbench rises slowly by electromotor and the blade revolves high-speed and repeated. According to the requirement of the customer, the machine can cut the whole material into 1-1000mm wafer. The advantage of this step is stable size and low defective percentage.

Milling.

The surface of the material can be processed into plane, vertical plane, inclined plane and different kinds of groove or formed surface by the rotary milling cutter of the machine. It also can be made into spiral groove, cam and the complex thread and spline shaft.

Cylindrical Cutting.

The parallel misalignment of the product can reach 0.01millimeters after cutting. The main reason to get accurate product is that the computer can control this machine.

Chamfering of edge

The quartz product’s edge or shape will be changed smooth and rounded. Because of this, it is not easy to broke and damage with eternal force for the quartz piece or other quartz product.

Grinding.

different kinds of lapping machines is chosen by producing different sizes, shapes, and accuracies products. In fact, it is not worry about the resistance of the grinding to damage the product. The reason is that the resistance is too small and it grides two sides evenly. The benefit of this step is high production efficiency.

Manual grinding.

The traditional manual grinding is took by the high accuracy quartz component from the customer. The technician of our factory own excellent workmanship and skillful technique. They can control the accuracy deviation under 0.07mm.

Polishing.

Workers is polishing the quartz material with polishing wheels. Polishing wheels are composed of canvases, felts and leather. The quartz piece is clamped by metal disks with polishing agent. The quartz piece become dazzling light after the speed of 20m/s..

Quality inspection

The high quality is reputation guaranteed of our factory. There is a set of scientific and rigorous quality control system in our factory no matter the raw material, semi-finish product and finished product. The final purpose is to satisfy the requirement of the customer.
