The ROTAFLEX high-performance hole-finishing system from WIDIA offers both roughing and precision finishing heads, however, it is a single system through a diameter range of 6 mm to 520 mm (0.236” to 20.4”). The KM-TS coupling and the newly developed RFX coupling are applicable to almost every machine spindle, provide easy assembly and disassembly and is an extremely stable operation, the company says. Because of the system upgrades, as much as 20 percent higher feed rates are possible in rough machining applications because of less vibration, resulting in increased machine tool productivity and longer intervals between scheduled maintenance.
The RFX coupling system is one major feature that is improved with the new Rotaflex. It no longer requires torque flats to disassemble. Instead, the coupling system features a bayonet-style coupling system that ensures cylinder face contact and better transmits torque forces. Two radial screws for clamping permit preloading the coupling and allow rotation in both directions. Standard insert pocket seats allow use of the carbide grades for higher running speeds.
Micro-adjustable cartridges for the Rotaflex system possess a radial adjustment mechanism that permits radial adjustment without affecting axial insert position.
