As a high-performance material, quartz glass is widely used in many fields such as optics, electronics, semiconductors, and chemical industries because of its high light transmittance, high temperature resistance, chemical stability, and low coefficient of expansion. The cold processing process of quartz glass refers to the process of physically changing the appearance and surface shape of quartz glass products without melting at high temperature.

Cold working process overview

The cold processing process of quartz glass mainly includes a series of machining steps such as cutting, grinding, polishing, punching, and grooving. These process steps process quartz glass raw materials into products of various shapes and sizes through high-precision mechanical equipment and professional processing technology to meet the needs of different fields.

Cutting process

Cutting is the first step in cold processing of quartz glass, and commonly used cutting methods include diamond wheel cutting, laser cutting, and high-pressure hydraulic cutting.

Diamond grinding wheel cutting: using a diamond grinding wheel cutting machine to cut quartz glass, suitable for thicker quartz glass materials.

Laser cutting: Using the high temperature of a laser beam to melt and cut quartz glass materials, it is suitable for cutting with high precision and complex shapes.

High-pressure hydraulic cutting: cutting quartz glass by carrying abrasive particles through high-pressure water flow, suitable for large-sized and thick quartz glass materials.

Grinding process

Grinding is the process of leveling the surface of cut quartz glass, which is divided into three stages: rough grinding, fine grinding and fine grinding.

Coarse grinding: Using coarse-grained abrasives and grinding equipment to remove burrs and uneven parts on the surface of quartz glass to achieve a certain geometric shape and roughness.

Fine grinding: use fine grain abrasives and grinding equipment to further smooth the surface, reduce surface defects and improve surface finish.

Fine grinding: the use of finer abrasives and precision grinding equipment to make final corrections to the surface of quartz glass to achieve extremely high finish and accuracy.

Polishing process

Polishing is the last step in cold processing of quartz glass, the purpose is to make the surface free of microscopic irregularities and achieve ideal optical properties. The polishing process usually uses a polishing machine and polishing paste to achieve extremely high smoothness and gloss on the surface of quartz glass through mechanical friction and chemical action.

Punching and slotting process

Punching: Use ultrasonic drilling machines, drilling machines and other equipment to punch the required holes in quartz glass. The punching process requires strict control of the position, diameter and depth of the holes to ensure the accuracy and quality of the product.

Grooving: Quartz glass is grooved using a slotting machine to meet the needs of a specific application. The grooving process requires precise control of the width, depth, and spacing of the grooves to ensure that the size and shape of the product meet the requirements.

Special processes and equipment

In the cold processing of quartz glass, some special processes and equipment are also involved, such as laser drilling, wire cutting, ultrasonic processing, etc. The application of these special processes and equipment further improves the accuracy and efficiency of quartz glass processing.

Laser drilling: using the high temperature of the laser beam to melt and punch quartz glass materials, suitable for high-precision and micro-hole drilling.

Wire cutting: Quartz glass is cut by the high frequency vibration of fine metal wires (such as molybdenum wires) under the action of electric field and the initialization of abrasive particles. Wire cutting is suitable for cutting with high precision and complex shapes.

Ultrasonic processing: Using the mechanical and chemical energy generated by ultrasonic vibration to process quartz glass. Ultrasonic processing is suitable for the processing of quartz glass products of small size and complex shape.

Precautions during processing

Quartz glass is a brittle material that is prone to edge collapse, bursting and breaking during cold processing. Therefore, the following points need to be paid attention to during processing:

Select the appropriate processing methods and equipment: According to the characteristics and processing requirements of quartz glass, choose the appropriate processing methods and equipment.

Control processing parameters: Strictly control the parameters during processing, such as cutting speed, grinding pressure, polishing time, etc., to ensure processing quality and efficiency.

Strengthening safety protection: During the cold processing of quartz glass, harmful factors such as dust and noise are generated, and safety protection measures need to be strengthened to ensure the safety and health of operators.

Application field

Quartz glass cold processing technology is widely used in many fields such as optics, electronics, semiconductors, and chemical industries. For example, in the field of optics, quartz glass is used to make optical components such as lenses and prisms; in the field of electronics, quartz glass is used to make integrated circuit substrates, packaging materials, etc.; in the field of semiconductors, quartz glass is used to make devices such as diffusion tubes and cleaning tanks; in the chemical industry, quartz glass is used to make equipment such as reaction kettles and distillation towers.

The cold processing process of quartz glass is a high-precision and high-efficiency processing method. Through a series of steps such as cutting, grinding, polishing, punching and grooving, quartz glass raw materials are processed into products of various shapes and sizes. These products are widely used in many fields such as optics, electronics, semiconductors and chemical industries, providing important support for the development of modern science and technology.
