Sharp Industries 220V 87” Heavy Duty Vertical & Horizontal Bed Type Mill KMA-3H

Description

This model has both vertical and horizontal heads. Bed type vertical mills are ideal for milling large work pieces or heavy cutting on hard metals. The quill is fixed so it can withstand strong lateral forces. For this model, the entire vertical head moves up to 28” that enables deep drilling and boring operations. The large spindle with #50 taper can remove large amounts of metals in one pass. The horizontal head with 7.5 HP motor and #50 taper spindle driven by AC servo motor on ballscrew performs horizontal milling operations with high accuracy.  This arrangement allows the performing of different types of milling operations on one set up, thus maintaining accuracy, and increase productivity.
