AG40 CNC EDM Blade Grinder

Description
AG40 CNC EDM grinding machine is mainly used for manufacturing and grinding PCD cutters in wood processing industry (Like composite floor and bamboo floor), Aluminium, printed circuit board, nonmetal material cutters and other PCD cutters.

Structure Characteristics of CNC Cutter Grinder
1. The mainframe uses C-type pedestal with cross feeds units structure.
2. The work piece dividing spindle adopts high precision harmonic reduction drive.
3. The high precision touch trigger probe is used to measure the cutters.
4. High precision variable speed electrode of R axis can auto-adapt electrode to turning cut and grinding cut.
5. Light sensation protection and temperature sensitive fire extinguisher ensure safety.

Technical Features of CNC Cutter Grinder
1. Configuring high efficiency and high finish-degree power for processing PCD. The wave of discharging is auto-adjusted during processing. Cutting efficiency is high and the quality of PCD cutter’s edge is excellent.
2. The special software of the cutters can process automatically as the parameters you set. Reduce the manual operation and can ensure good consitency.
3. Tooth pitch of disc-type cutter can be measured automatically, automatic indexing, self-compensation and automatic processing.
