Introduction TKF type How to Use Main spindle 1) When using main spindle only Maximum cutting diameter is CUTDIA (Fig.1). 1 CUTDIA Even if the cutting edge runs beyond the center line, the insert does not contact the workpiece, since the workpiece falls off. ( The clearance between the insert and the workpiece is 0.2 mm) Fig.1 Fig.2 (When the edge is at the center) (When the edge is 1mm beyond the center) 2) When using both main and sub spindles Main spindle Sub spindle In this case, when the cutting edge runs beyond the center line, the insert will contact the workpiece, since the workpiece does not fall off. CUTDIA2 e.g.) When the cutting edge is programmed to run 1mm beyond the center. 1 Workpiece maximum, CUTDIA2 (Fig.4) = [CUTDIA −1 mm×2] (mm) (The clearance between the insert and the workpiece is 0.2 mm) H Fig.3 Fig.4 (When the edge is at the center) (When the edge is 1mm beyond the center) Cut-Off How to select edge preparation Troubleshooting Countermeasures Lead angle (PSIRR) Edge width Name of chipbreaker Neutral (0°) Yes Narrower Wider S T NB Problems Countermeasures Insert fracture Insert fracture prevention Effective Effective Effective Effective Long cutting time Cutting time reduction Effective Effective Effective Effective Prevention of chip Entangled chips Effective Effective Effective entanglement Large boss remain Small boss remain Effective Effective Effective Ring remain Prevention of Effective Effective Effective (Hollow workpiece) ring remain Deformation of hollow Preventing deformation Effective Effective Effective workpiece (pipe) H12
