Vertical 3-Axis CNC Optical Polishing Machine for Spherical and Aspherical Surface Finishing

YCG-85 is a grinder with three CNC axis for spherical and aspherical lenses. The working range is Dia. 10mm to 120mm with less than 1μm for SAG depth. Easy input all the data with the Interface, easy to run the machine. 500 workpiece data can be memory for picking up in future.

The machines use linear scale from FAGOR Spanish for X-axis, and Z-axis. The resolution of this linear scale is 0.1μm. An angle scale from Renishaw UK used on B-axis, and resolution is 1 arc second. All these keep the machine in high accuracy and reliable.

1. The machine base on natural granite, low deformation with the temperature.
2. All the driving parts such as linear guide and ball screw are from HIWIN Taiwan. Meet all the accuracy which designed, and keep the machine in high accuracy and reliable.
3. All the bearings for rotating parts are from FAG Germany, keep the rotate accuracy less than 3μm.

The chiller is used for coolant system, to keep the spindle and coolant working in the certain temperature. Filtering centrifuge keeps coolant clean and constant temperature.

It is mainly used for spherical surface polishing, aspherical surface finishing, optical lens polishing, mirror polishing, mold polishing, curved surface finishing, and precision optical surface processing.

A vertical structure provides convenient operation, stable workpiece positioning, compact layout, and reliable processing stability for precision surface finishing.

The 3-axis CNC system controls polishing tool movement, polishing path, feed rate, polishing speed, processing time, and other parameters to improve repeatability and surface consistency.

It can polish optical glass, K9 glass, quartz, crystal materials, ceramics, mold steel, non-ferrous metals, and other precision materials depending on polishing tools, abrasives, fixtures, and process conditions.

Yes. The 3-axis CNC control system can support controlled polishing paths for aspherical surfaces, spherical surfaces, curved surfaces, and precision optical components.

Yes. It is suitable for fine polishing after grinding, milling, or precision machining. It helps remove surface marks and improve final surface quality.

Please provide workpiece material, size, surface type, spherical or aspherical requirement, required surface quality, production quantity, polishing process, and preferred machine configuration.
