P10 A P20 A P30 K01 A K10 A K20 Reduce feed rates. Select a negative-positive cutter configuration with a large approach angle. Reinforce the cutting edge (Honing). Select a strong edge insert (G g H). - Recommended insert grades Steel Cast Iron Finishing ACP200 (Coated Carbide) ACK200 (Coated Carbide) Roughing ACP300 (Coated Carbide) ACK300 (Coated Carbide) Recommended cutter: WaveMill WGX type Cutting conditions: Refer to recommended conditions listed in the general catalogue Partial Fracture of Cutting Edges ool Material Cutting Conditions ool Design If it is due to excessive low speeds or very low feed rates, select an adhesion resistant grade. If it is due to thermal cracking, select a thermal impact resistant grade. Select appropriate conditions with regards to the particular application. Select a negative-positive (or negative) cutter configuration with a large approach angle. Reinforce the cutting edge (Honing). Select a strong edge insert (G g H). Increase insert size -( hickness in particular). Recommended insert grades Steel Cast Iron Roughing ACP300 (Coated Carbide) ACK300 (Coated Carbide) Recommended cutter: WaveMill WGX type Insert thickness: 3,18 g 4,76mm Insert type: Standard g Strong edge type Cutting conditions: Refer to recommended conditions listed in the general catalogue Unsatisfactory Machined Surface Finish ool Material Cutting Conditions ool Design - Select an adhesion resistant grade. Carbide g Cermet - Increase cutting speeds. - Improve axial run-out of cutting edges. (Use a cutter with less run-out) (Attach correct inserts) - Use wiper inserts. - Use special purpose cutters designed for finishing. - Recommended insert grades Steel Cast Iron Non-Ferrous Alloy Roughing Cutter Insert WGX type ACP200 (Coated Carbide) DGC type ACK200 (Coated Carbide) FF type H1 (Carbide) DL1000 (Coated Carbide) 1 Finishing Cutter Insert WGC type T250A (Cermet) FMU type BN700 (SUMIBORON) RF type DA1000 (SUMIDIA) marked cutters can be fitted with wiper inserts. Chattering s r e Cutting Conditions Tool Design Others - Reduce feed rates. - Select a high rake cutter with sharp cutting edges - Use an irregular pitched cutter. - Improve workpiece and cutter clamp rigidity. Recommended cutters: For steel: WaveMill WGX type For cast iron: DNX type For Non-ferrous alloy: High speed cutter for aluminium RF type Unsatisfactory Chip Control Tool Design Select cutter with good chip removal features. Reduce number of teeth. Enlarge chip pocket. Recommended cutter: WaveMill WGX type Edge Chipping on Workpiece Tool Design Cutting Conditions Select a large approach angle. Select a sharp cutting edge insert (G g L). Reduce feed rates. - Recommended cutter: WaveMill WGX type Burr on Workpiece Tool Design Cutting Conditions Select a cutter with sharp cutting edges. Increase feed rates. Recommended cutter: WaveMill WGX type + FG breaker DGC type + FG breaker N9 Technical Guidance
