- Extra Heavy Duty Spindle - designed for CBN and PCD tooling. Large diameter, hard chromed tool steel spindle utilizes high precision triple angular contact bearings resulting in many years of super fine surface finishes.
- Reduced Floor Space - Compact, one piece castings and multi layer slideway guards give the most compact surfacing machines available today.
- Super Fine Surface Finish - Belt driven precision ball screw and infinitely variable speeds and feeds allows surface finished as low as 2Ra to 6Ra for today's MLS (Multi Layer Steel) head gaskets.
- Dry Cutting System - Eliminates coolant disposal and makes clean up a breeze! Cutterhead shroud directs dust and chips into optional vacuum system.
- Return to Vertical Zero - The cutterhead always stays at vertical zero - ready for the next pass.
- Latest Control Technology - State of the art closed loop electronic controls make the most advanced surfacing machines available today.
- Protection and Long Life - Multi Layer Steel Guards cover and protect the slideways for extra long service life.
- Fast Floor to Floor Time - Heads can be surfaced in less than 2 minutes and a pair of V8 heads in less than 8 minutes.
