1 No: MGMN-G Features - Unique W shape strong clamping system ensures stability of machining - M.G.T Insert can be used at Internal operations as well as External operations - M.G.T Insert s M chip breaker covers a wide range of application from finishing to roughing - M.G.T has wide application range because a M.G.T Holder can adopt various inserts MGMN-M MRMN-M MRGN-A

2 Application Range of MGMN Inserts Recommended Grade M.G.T for External Machining Application Range of MGMN Inserts Depth of cut (mm) Cutting Speed : 120~180(m/min) Workpiece : 42CrMo4 - (DIN) MGMN1 MGMN MGMN0 MGMN0-M MGMN0-M MGMN0-M Feed (mm/rev) Depth of cut, feed and Width of Cutting edge If the depth of cut and feed are too bigger than the width of cutting edge, it may bring to breakage due to increasing of cutting resistance of insert. If the depth of cut and feed are too smaller than the width of cutting edge, it may lead to a vibration or unstable machining due to no formation of the sub cutting edge relief angle against no direct influence of tool deflection.
