MIDSIZE DIAMOND TURNING LATHE
Our mid-size lathe option. If your application fits within a 450mm diameter swing capacity (larger available upon request), this machine may be the ideal solution for your ultra precision needs. The larger slides make this system suitable for both diamond turning and grinding while enabling larger multi-tool production setups. Applications include the manufacture of components used in a wide variety of markets such as electro-optics, aerospace, defense, consumer electronics, bearing, and computer industries.
Optional C Rotary with Linear Y
or Rotary B Axis
Expansion of the basic 2-axis system is simple. One can have up to 4 axes of continuous path motion via the addition of C & B or C & Y. The C-axis motion control of the work spindle enables toric, biconic, and other freeform surfaces to be machined “on-axis” via our Slow Slide Servo (S3) process. Our Oil Hydrostatic Rotary B-axis or removable Vertical Linear Oil Hydrostatic Y- axis can be configured independently on the Z-axis carriage for future added flexibility.
