Insert that have larger lead angles reduce burrs but will also decreases tool life In the case where burrs are acceptable, we recommend using a neutral type insert Parting off on small diameter and hollow bar type Reduce the burr and center stub when parting off on small diameter solid bar type 0 Setting of holders The cutting position should be exactly mounted on machined axis in order to create a perpendicular direction or 90 to minimize vibration O Setting of parting off The edge height of an insert should be set within ±0.1mm based on the center line Parting off should be done as close to the chuck as possible to minimize vibration O Notice Keep a consistent cutting speed and feed Use proper amounts of coolant for better performance Properly clean the insert pocket before mounting insert O 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 O Selection of chip breaker Our chip breakers are designed to narrow chips during grooving operations. Narrow chips usually offer the following advantages Decreases 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 A 5
