GENERAL TECHNICAL INFORMATION ■ Machining ■ Insertion and Extraction of Insert • Consistency of speed and feed improves performance. • Apply coolant abundantly (excluding Ceramic AB30). • Secure insert into clean pockets. T-Clamp Ultra Insert Clamping • Cutting forces on soft workpiece materials may be insufficient to push insert well into pocket. Tap insert into place using a plastic hammer. Insert mounting • On a conventional lathe, lock the carriage to prevent By hand or axial motion during cut off. with plastic hammer. ■ Usage • Replace worn inserts promptly. Insert Extraction The price of a new one is much less than the risk of damage from continuing with one that is worn out. With extractor key. • Replace blades having worn or damaged pockets. • Never try to repair damaged pockets. ■ Chipbreaker The chipbreaker’s function is to narrow the chip- it occurs near the cutting edge in the region of high temperature. Producing chips that are narrower than the groove gives the following advantages : Eliminates frictions with groove walls Prevents chip overload Permits higher feeds Produces unscratched surfaces, eliminating additional facing. Curling the chips into compact spirals or breaking them short is ideal for easy disposal. Curling is affected by the chipbreaker type and the machining conditions. Facilitate ease of cut by selection of an appropriate chipformer for the specific application. 1370
