Face Milling Cutter’s Entering Angle Increases Productivity
Sandvik Coromant has unveiled a high-feed version of the CoroMill 745 face milling cutter, featuring a 25-degree entering angle for productivity gains when milling steel and cast-iron workpieces.
Sandvik Coromant has unveiled a high-feed version of the CoroMill 745 face milling cutter, featuring a 25-degree entering angle for productivity gains when milling steel and cast-iron workpieces. It facilitates high metal removal rates in applications with depths of cut ranging to 2.8 mm (0.110") without compromising surface finish, according to the company. The cutter is suited for industries including die/mold, pump and valve, oil and gas, automotive, power generation, and general engineering. Light cutting action from the insert’s position is said to provide good chip formation, a soft sound and low power consumption.
The double-sided, 14-edge insert design reduces cost per edge. The cutter also uses the same inserts as the company’s 42-degree angle cutter for further potential inventory cost reduction.
The cutter is aimed at roughing to semi-finishing face milling operations on machining centers and multitasking machines. The multi-edge concept suits it for large batch production and flexible transfer. A short (0.6 mm/0.024"), parallel land is designed to ensure good surface finish. The large screws ease handling, while the insert position and the heptagonal shape ensure secure clamping for reliability. Internal coolant is available for cutters ranging from 63 to 160 mm (2.5" to 6.0").
The right choices in tooling and technique can optimize the thread turning process.
Running rotary milling cutters at the proper speeds and feeds is critical to obtaining long tool life and superior results, and a good place to start is with the manufacturer's recommendations. These formulas and tips provide useful guidelines.
Reducing cutting fluid use offers the chance for considerable cost savings. Tool life may even improve.
