The processing of quartz glass tubes is a complex and delicate process involving multiple steps and processes. The following is a detailed analysis of the quartz glass tubes processing:

I. Processing Flow

The manufacture of quartz glass tubes is mainly completed through the following process steps:

Raw material selection: select high purity quartz sand or other quartz raw materials as raw materials to ensure the purity and quality of the product.

Pre-processing: pre-treatment of raw materials, such as washing, drying and other pre-treatment work, in order to remove impurities and moisture, in order to prepare for the subsequent processing.

Melting: The pre-treated quartz raw materials are put into the melting furnace and melted at high temperature to form fused quartz. This process requires precise temperature control to ensure the uniformity and quality of the molten quartz.

Tube and Bar Preparation: Through specific processes and equipment, the fused quartz is formed into tubes or bars. This step requires control of melt distribution, drawing speed, and other factors to ensure the quality of the tubes and rods.

Drawing or molding: Depending on the needs, the tubes and rods are further drawn into finer quartz glass tubes, or molded into specific shapes.

Annealing: The processed quartz glass tubes are annealed to eliminate internal stresses and improve product stability and service life.

Surface treatment: Polishing, etching and other surface treatments are carried out on the quartz glass tubes to achieve the required surface finish and precision.

II, the processing method

In the processing of quartz glass tubes, commonly used processing methods include:

Laser processing: laser processing is currently the most commonly used processing method in the processing of quartz glass tubes. The laser beam scans or cuts the surface of the quartz glass tubes, which can realize fine processing, and has the advantages of high efficiency and controllability.

Mechanical Processing: It is processed by universal grinder, CNC lathe, CNC milling machine and other equipment, which is suitable for simple shape and small batch production.

Chemical processing: mainly using etching, polishing and other technologies to deal with the surface of the quartz glass tubes, able to achieve high precision and high finish and other requirements of the processing.

III, quality control

Quartz glass tubes processing quality control needs to be carried out from a variety of aspects:

Raw material control: strict control of the purity of raw materials and selection to ensure the basic quality of the product.

Manufacturing process control: in the manufacturing process, the need to control the temperature, melt distribution, drawing speed and other factors to ensure the quality of the rod.

Process control: Pay attention to the control of process parameters, such as processing speed, laser power, etc., to ensure processing accuracy and efficiency.

Surface treatment control: control the etching time, the use of polishing materials, etc., in order to obtain the required surface finish and precision.

Quality inspection: Appearance inspection, dimensional accuracy testing, transmittance testing, etc., to ensure that the product meets the quality requirements.

IV, special processing methods

For quartz glass tubes of specific shapes or requirements, the following special processing methods may also be used:

Cold Processing: Use quartz tube, quartz rod, etc. as raw materials for slicing, grooving, punching, grinding, polishing and other mechanical processing into products.

Thermal processing: quartz tubes and rods are heated to a soft state with a hydroxide flame, and then blown, pulled, jointed, welded, and other manual operations are used to manufacture products. This method is commonly used in the manufacture of complex shapes of quartz glass instruments and utensils.

The processing of quartz glass tubes is a complex and delicate process, which requires all-round consideration and control from raw materials, manufacturing process, processing methods, quality control and other aspects.
