CNC spark erosion
Our CNC die sink EDM's are incredibly flexible, fast and accurate. With automatic tool changing that can hold up 16 electrodes tool, rotating ‘C’axis and up to 1200x750mm in the work tank, CGP can tackle most projects. Our EDM's can provide consistent surface finishes and textures along with time and cost saving ‘lights out’ production.
We have two die sinks on site, the biggest having a movement of 750x500mm in the X and Y axis. Both machines are accurate to within 0.01mm or better! Your jobs will be completed with the capability to exactly repeat the job, you expect with new generation machines.
We have sparked jobs for mould makers, pattern makers, aerospace and precision engineering companies, enabling them to complete projects without having to invest in expensive machinery.
The newest of our CNC sparkers is fitted with frictionless linear drives which provide better repeatability over time. This enables us to obtain consistent, accurate finishes, faster and with less wear. The bulk of our electrodes are manufactured by graphite but they can change dependant on customer spec and part geometry.
Both machines have the function to rotate and control the C-axis whilst sparking - essential for helical forms such as threads that need to be added after a part has been hardened. Undercuts are also easily catered for as are sub gates.
All of our spark erosion machines are fitted with Erowa chucks. These enable accurate, reliable and swift electrode transfer.
