High Efficiency Cutter for Aluminum Alloy Expansion HF Type ■ General Features The HF type high efficiency cutter for aluminum alloy achieves machining without burrs using a unique insert shape. New HFFH types with oil holes and BBT30 (BIG-PLUS™BT30) integrated arbor types are available. Work Material ・Aluminum and aluminum alloys （ ） Not suitable for ・Other non-ferrous metal cast iron or steel. ■ Characteristics ● Achieves high-efficiency milling with Vf of over 20,000mm/min thanks to more teeth (3 edges per inch). High Feed, High-efficiency Milling with more teeth Conventional Tool 2,880mm/min fz=0.08mm/t 3.4 Times Machining Efficiency HFF12080R 9,800mm/min fz=0.16mm/t 0 2,500 5,000 7,500 10,000 vf (mm/min) ●Maximum Allowable Spindle Speed and Feed Rate Cutter n max vc fz Max.

Drastically reduces burrs by Conv. Edge Double-Chamfe Edge preventing the plastic deformation Main Chamfer that causes burrs. 25° 25° Sub Chamfer Work Material：A6061 Blanks  0.416mm Burrs are formed. No Burrs Cutting Conditions：vc=3,142m/min, fz=0.10mm/t, ap=0.5mm, Dry ● The wedge clamp with anti-scattering mechanism ensures safety and simple operation. Clamping U Unclamping Anti-scattering Anti-scattering Stopper Stopper N m 6.0 Enables Easy Run-Out Correction HFJ Do not exceed the maximum allowable spindle speed (n max) specified for each cutter diameter. (*See the table on the upper right.) ● Reduces running costs by significantly increased number of regrinding (to 1.8mm). Assuming the amount of regrinding to be 0.2mm, an edge can be used Max. Regrinding Amount up to 10 times. 1.8mm M （* Given the condition of normal wear with ap of 1.4mm or less） SUMIDIA Regrinding Portion The regrinding amount has been significantly increased compared to conventional screw-lock types. ● Improved chip evacuation with internal coolant (HFFH type and HFFH-BBT30 type) SUMIDIA The effect of internal coolant controls chip blockages and packing in the work SUMIDIA Binderless SUMICRYSTAL material and improves tool life. (Use an arbor that supports internal coolant.) BIG-PLUS™ is a trademark of BIG DAISHOWA SEIKI CO., LTD. Can also be used with BT30 spindle machines. M30
