High-Efficiency Cutter for Aluminum Alloys SRF Series
■ General Features The SRF small diameter aluminum alloy cutter is ideal for aluminum alloy machining on high-performance small machines.
H
■ Features ● Ideal for small machines
Especially reliable on BT30 class small machines. ● From roughing to finishing processes Utilizes SUMIDIA DA1000 inserts with effective cutting edge length of 5mm ● Economical NF-type Inserts: NF Type SUMIDIA inserts with tough DA1000 grade lower tooling costs. ● High-speed Cutting with PCD-SUMIDIA: Maximum spindle speeds of up to n = 20,000 RPM (Actual spindle speeds must be set within the rotational limits of your machine and holder) ● Simple Runout Adjustment Mechanism: Simple insert direct mounting design for runout precision with easy fine adjustment
