Multi Functinal lathe Tools Korloy Parting off and Grooving Insert Lead angle applications Lead angle 0°(Neutral) Lead angle 4° 8° Lead angle 8° 15° Lead angle(°) 4°- Pipe (Tubing and hollow bar) 6°- Pipe and solid bar 8°- Solid bar 15°- Small diameter Solid bar Parting off on solid bar type Occurring the center stub when parting off Prevent to be deflected workpiece by cutting diretion during parting off Availble for use deep parting depth Available Inserts MGMR/L - - PS/PT, KGMR/L- - LP/RP (Lead angle) (Lead angle) Reduce the center stub when parting off on solid bar type Reduce the burr when parting off on tubing or hollow bar type Parting off on small diameter and hollow bar type Reduce the burr and center stub when parting off on small diameter solid bar type Selection of Insert To properly match the insert and cutting condition, the following factors should be considered Width of insert Chip breaker Grade and nose R The relationship between the cutting width and cutting depth Neutral type, inserts with a 0 degree lead angle are best when used an applications maximum depth of cut In general alloy steel, the maximum depth of cut = W x 0.8 Insert with lead angle To reduce burrs, we recommend using insert with a lead angle. Insert that have larger lead angles reduce burrs but will also deareases tool life. In the case where burrs are acceptable, we recommend using a neutral type insert Setting of Holders Setting of Parting off The cutting position should be exactly mounted on machined axis in order to create a perpendicular direction or 9O to minimize vibration The edge height of an insert should be set within ±O.1mm based on the center line Parting off should be done as close to the chuck as possible to minimize vibration Notice Keep a consistent cutting speed and feed Use proper amounts of coolant for better performance Properly clean the insert pocket before mounting insert Usage If insert is worn, immediately replace with a new insert. This is to prevent the damage on the workpiece If the holder seat is worn or damaged replace with a new one immediately for stable clamping Do not grind or regrind the holder seat Selection of Chip Breaker mm Our chip breakers are designed to narrow chips during grooving operations. Narrow chips usually offer the following advantages Deareases friction between chips and the workpiece. This usually gives a better surface roughness finish With better chip flow, a machinist is able to increase feed rates due to a reduced cutting load Multi functional Tools 6 Technical Information for Series
