PRG6DX・PRG8DX

CONCEPT

Original controller achieved 0.1µｍ infeed and is easy to operate.

Feature

・By adopting bridge (double column) structure, stable infeed and high precision is realized. Eazy loading/unloading due to lower position and wide open chuck area, because spindle unit traversing on double column slideway. Table designed lower position for easy loading/unloading; widen and open area for easy operation.

・Own developed controller is control Vertical infeed and Cross infeed by AC servo motor. Min. Vertical infeed setting is 0.1μm.

・Automatic cycle is Coarse grinding ⇒ Fine grinding ⇒ Spark-out ⇒ Step at workpiece peripheral end.Possible to chenge the settings of downfeed by step amount, table rotation speed, total remaining grinding allowance and variable speed even during automatic cycle, table step less speed.
