Widia Rotaflex upgrades boost performance

The upgrades offer up to 20 per cent higher feed rates in rough machining applications, due to less vibration, resulting in increased machine tool productivity and longer intervals between scheduled maintenance. With the RFX coupling system - an addition to the existing KM-TS coupling - there is no longer the requirement for torque flats to disassemble the system. Instead, the RFX coupling system features a bayonet-style coupling 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 industry-leading Widia carbide grades for higher running speeds. The micro-adjustable cartridges possess a proprietary radial adjustment mechanism that permits radial adjustment without affecting axial insert position. Higher hole-finishing accuracy and easier adjustment are the results. With both roughing and precision finishing heads available, Rotaflex is a single Widia system for both roughing and fine-finishing operations over a broad diameter range — 6 mm to 520 mm (.236 in. to 20.4 in).
