Spindle Polishing Machines For Optical Lenses


Optical lenses are processed by high speed fine grinding buffing machines. The main objective of these polishing machine is to achieve the surface roughness of the lens with a certain radius. This kind of technology can be applied to optical lenses of different shapes. Depending on the requirement, the optics can be polished using the high-speed or the classic finishing method.

To increase the efficiency of production, the present invention combines the High-speed fine grinding finishing method and the classical finishing method. With the use of this technology, the labor intensity is reduced. Also, the process flow is shortened, which saves the cost. In addition, the production effect rate is improved.

The present invention has a compact and convenient design. It is very easy to operate. Additionally, the noise level is moderate. Compared to traditional polishing machines, it is simple to control the working speed. Moreover, each spindle has an amp-meter, which can regulate the degree of contact with the glass. Using this device, the operator can easily determine the degree of contact with the glass.

Another advantage of the present invention is that the surface roughness is improved. Since the diamond pellets are used in place of shot sand, it reduces the labor intensity and increases the production effect. Moreover, the urethane film is pre-polished. Hence, there is no risk of abrasion on the lens surface. Furthermore, the present invention enables the user to carry out the pre-polishing on the high-speed glazing machine.

Using this method, the workpiece is fixed in a clamping ring. Then, the urethane film is adhered to the mould at a high speed. After that, the urethane is polished to improve the quality.

The use of the diamond lap sheet is also applicable to various types of optical glass. Besides, the granules can be chosen according to the concentration and the type of the optical glass. The diamond lap sheet can be made of metal or resin as the bonding agent.

The first corase grind is the grind which controls the lens-shape profile. Once the lens-shape profile is refined, the table is removed. For medium-small diameter flint glass, a secondary mill is required. These methods can be combined with the high-speed fine grinding finishing method, and the finished product is standardized.

Optical spindle polishing is a process which requires a high school diploma. You may need to be familiar with measurement tools and written work instructions. However, a metal finishing technician must also follow verbal work instructions and safety regulations. Moreover, the technician must know the requirements of the ASML 5S and other requirements. Besides, the technicians are also exposed to laser energy. Therefore, the technician should take special measures to protect himself.

As with any other equipment, the safety measures must be followed. The technician is regularly exposed to moving mechanical parts, and therefore, must be careful. All of these precautions are necessary to ensure the safety of the users and the machine. In addition, the operation is controlled by the motor variator.
