ACRA MODEL MN-2 UNIVERSAL TOOL & CUTTER GRINDER WITH BALL SCREW

• Capability for multiple grinding operations at single chucking of work piece saves setup time, assures excellent concentrically.
• Versatility for generating straight or tapered, right or left hand, infinitely variable leads from a simple built-in lead mechanism.
• Turntables mounting of entire work head slide assembly, adjustable through 235 plus degrees in the horizontal plane has proved to be a real asset when grinding radius.
• Adjustable is work head on separated slide with dual hand wheel control has proved to be a boost for setups.
