Recommendations for High Speed Machining at 8000 RPM or above • Check spindle condition:   • Before start up, note the maximum RPM engraved on the tool. - Runout The maximum RPM is linked to a precise balancing value.  - Clamping of the attachment in traction • Ensure that the field of application of the tool shown in - Marking and cleanliness our technical documents and technological parameters is observed:  • Check that the tool is suitable for the required use.  Ae (mm) Width of cut, lateral engagement • Inserts must be locked positively in the pocket and secured using the (radial) torx screw provided. The screw must be torqued to the correct value asindicated in the charts on the product pages. ap (mm)Axial depth of cut fz (mm/tooth) mm per tooth • Because of heavy force to the screw, it is important to change thescrew when changing the insert. n (RPM)Revolutions per minute • Check the balancing of the assembled tool: cutter body, inserts, and attachment.  WIDIA™ cannot accept responsibility for misuse of this product due to: • Non-observance of the above instructions  • Machine without casing  • Incorrect clamping of workpieces  • No safety device on the machine  • Any misuse or incorrect clamping  The optimum rotation must be determined by condition of the spindle. The spindle must be rigid to run at these higher RPMs. Under no circumstances must any attempt be made to repair this tool. The only permitted maintenance is the indexing or replacement of the inserts. When assembling the cutter to a Shrink Fit holder, the maximum protrusion cannot exceed 10% of the reach of tool. Balancing: • Cylindrical shank and HSK63A integral shanks are designed and balanced to G6.3 Tighten the bolt between the shell mill and toolholder; at 30000 RPM for diameters up to 50mm.  with lubricant, apply the torque value of: • Cylindrical shank tools mounted in a Shrink Fit holder or any other chuck mill holder + inserts + screws must be re-inspected for balance as an assembly by the end-user Thread sizes Cutter Bore Size Torque Values when at or exceeding 8000 RPM. End-user must balance the assembly at a G6.3 at30000 RPM maximum.  (mm) (mm) Nm • Shell mills are not balanced. These tools must be re-inspected for balance as an M6 13 10 assembly, cutter + inserts + screws by the end-user for high speed machining at M8 16 30 8000 RPM or above. End-user must balance the assembly at a G6.3 value minimum.  M10 22 50 • Balancing requires removing some material by drilling or milling operations.  • For each new shell mill installed on the same toolholder, re-balance the assembly.  M12 27 80 M16 32 110 M20 40 120 widia.com 63
