Aluminium Alloy Milling Cutter SRF Type ■ General Features The small diameter milling cutter SRF type for Aluminum alloy is most suited to high-efficiency machining of aluminum alloys on small machines. ■ Characteristics D Best Suited For Small Machines Especially reliable on BT30 class small machines. D From Roughing To Finishing Processes Utilising SUMIDIA DA1000 Insert with a side edge of 5mm. D Economical NF-type Inserts NF-type SUMIDIA DA1000 inserts lower tooling costs. D High Speed Cutting With SUMIDIA Maximum spindle speeds of up to n = 20,000min-1 (Actual spindle speeds must be set within the rotational limits of your machine and arbor. ) D Simple design for insert run-out Simple insert mounting design for easy yet precise tool adjustments. ■ Application Examples Work Cutter Cutting Conditions Insert n = Spindle Speed (min-1) Results (Work Material) (Grade) vf = Feed Rate (mm/min) ap = Depth of Cut (mm) Cam Case SRF50R n =6,000 12,000 pcs produced with no (ADC12) NF-SNEW09T3ADTR vf =2,400 problems.
