Grinding Wheel Speed Calculator | Norton Abrasives

Grinding Wheel Speed Calculator. All Norton grinding wheels are marked with a maximum operating speed in RPM. Most machines, and especially CNC machines, use Surface Feet Per Minute (SFPM) as an input, which requires operators to do the conversion. This calculator will do this by inputting the wheel diameter in either English units or metric, then inputting the RPM to calculate SFPM or MPS.进一步探索GRINDING FEEDS AND SPEEDS - ABRASIVE ENGINEERINGwww.abrasiveengineering.comGrinding Wheel Safety: Respect The Maximum Speed | Modern ...www.mmsonline.comSpeeds and Feeds Calculator - Good Calculatorsgoodcalculators.comGRINDING PARAMETERS CONVERSION CALCULATORwww.abrasiveengineering.comCalculating RPM | Mach-B Grinding Wheel Shaping & Resizingwww.mach-b.com根据热度为您推荐•反馈

GRINDING FEEDS AND SPEEDS - ABRASIVE ENGINEERING

The wheel speed, in terms of peripheral speed, is commonly in the range of 5,500 to 6,500 fpm (about 30 to 35 m/sec). High-speed grinding, operating at about twice that speed, is used on specially built surface grinding machines only, which are designed generally for abrasive machining and require appropriately manufactured grinding wheels.
