GENERAL TECHNICAL INFORMATION PARTING AND GROOVING 90 MOUNTING The insert must be mounted 90 to the workpiece to obtain perpendicular surfaces to minimize vibration. SET-UP The center height of the insert should be maintained within 0.004"The parting operation should be as close to the chuck as possible SELECTING PREFERENCE PRIORITY Use insert with 0 lead angle. Use largest blade size as possible Use smallest appropriate width of cut MOUNTING OF INSERT MACHINING Consistency of speed and feed improves performance Apply coolant abundantly (excluding Ceramic AB30) Secure insert into clean pockets On a conventional lathe lock the carriage to prevent axial motion during parting-off USAGE Replace worn inserts immediately. The price of a new insert is much less than the risk of damage from continuing with a worn edge. Replace blades having worn or damaged pockets Never try to repair damaged pockets CHIPBREAKER The function of the chipbreaker is a controlled removal of the chips from the cutting range. Therefore the width of the chips are reduced by the chipbreaker. Chips with reduced width have the following advantages Eliminates friction with groove walls Prevents chip overload Permits higher feeds Produces unscratched surfaces eliminating additional facing Curling chips into compact spirals or breaking chips simplifies disposal. Curling is affected by the chipbreaker type and the machining conditions. 1349
