What should we pay attention to in the process of processing optical blank glass?

The core of processing optical blank glass is to avoid defects, ensure accuracy and protect glass properties.

Core considerations

Environmental control: keep the processing environment clean and dry. Dust and humidity will affect the surface quality of glass, and the temperature fluctuation should be controlled within 1℃.

Material protection: avoid direct collision between glass and hard objects, and wear powder-free gloves when taking them to prevent fingerprints and oil residue.

Processing parameters: control the pressure evenly during cutting to avoid microcracks; In the grinding and polishing stage, the matching abrasive particle size is selected, and the machining allowance is controlled to gradually decrease.

Cleaning treatment: after processing, clean with special cleaning agent to avoid residual abrasives or impurities. After cleaning, air dry naturally or blow dry with clean gas.

Safety and quality control

Equipment maintenance: regularly calibrate the accuracy of processing equipment to ensure that tools and abrasives are not worn or deformed.

Inspection and follow-up: visual inspection and size measurement are carried out after the key process, and defects such as cracks and scratches are found in time.

Personnel operation: Operators should be trained professionally and be familiar with equipment operation procedures to avoid glass damage caused by illegal operation.
