SpinJet – Pump Casing


High productive machining
- Groove milling on the flange of pump casings requires a small-diameter tool. The machine’s max RPM is not enough for the desirable Vc, which reduces the tool life and deteriorates the machined surface quality.Short cycle time is also required. Tungaloy’s Spinjet, the coolant-driven holder for highspeed rotation, improves productivity, tool life, and surface quality.
