INTRODUCTION

This manual is a guide to your Cutter Grindeer. With diagrams and description it shows how to grind most types of single point cutters. Details of general maintenance are also given so that by correct maintenance you can ensure maximum service from the equipment.

The 2CGD will take cutters up to 11/16 inch (17.5mm) diameter and cutters can be ground accurately and quickly to the best clearance and cutting angles for the material being machined. Dividing scales marked in degrees allow the work head to be rotated horizontally and vertically to give universal movement to the slide. A third cross slide fitted with a vernier scale graduated in 0.001 inch or 0.01 mm divisions will offset the cutter for grinding off centre radii.

Read the instructions in this manual carefully, they will help to ensure that your Cutter Grinder is used correctly and gives good service in shaping and sharpening cutters.
