Milling grinding wheel for optical glass is mainly used for spherical processing, end face milling and side grinding of optical glass, crystal, and ceramic. It is suitable for spherical glass such as cameras, microscopes, sights, telescopes, etc. Diamond milling grinding wheel is used in the previous process of diamond pellet grinding. The milling quality affects the finish grinding quality of optical glass.

Advantages of Diamond Milling Grinding Wheel for Optical Glass:

Cylindrical diamond milling wheel which is made by special process for manufacturing diamond pellets (内链) features high cutting force, high cutting efficiency, long life, uniform wear, and good machining surface quality.

Metal bond and resin bond diamond milling grinding wheels are available.

Our company’s cylindrical diamond milling wheels have complete specifications and a wide range of applications, which can perform high precision milling on various glass materials.

Parameters of diamond milling grinding wheel for optical glass

When customizing milling grinding wheels for optic glass, the following notes should be taken:

According to the processed lens, milling wheel diameter is usually about two-thirds of the processed lens diameter. As the grinding wheel diameter increases, the linear speed increases, and the grinding rate increases accordingly. Typically, if milling the optical components with larger diameters and higher hardness, the diamond grain size of milling wheel is coarser. If milling the optical components with smaller diameters or higher surface quality requirements, it can choose milling wheel with finer diamond powder.

Match with the connecting shaft of the equipment.

The radial and axial runout of diamond milling grinding wheel for optic glass should meet the processing requirements, otherwise it will damage the optical lenses or even explode, causing harm to the operator.

When customizing milling grinding wheels, an increase of milling wheel wall thickness can lead to a decrease in processing efficiency due to an increase in contact area. Usually, the wall thickness of milling wheel should not over 2mm for the wheel with a diameter of less than 20mm. The wall thickness of diamond milling wheel should no more than 3mm for the diameter of 20-50mm.

The increase in the effective grinding layer height of the diamond milling wheel can easily cause looseness in the middle section of the milling grinding wheel and affect the consistency of the machining.

For diamond milling grinding wheels with a diameter of less than 6mm, the effective grinding layer should not over 5mm in height, and for milling wheels with a diameter more than 6mm, it is better not to over 7-10mm.
