A grinding machine, often shortened to grinder, is any of various power tools or machine tools used for grinding, which is a type of machining using an abrasive wheel as the cutting tool. Each grain of abrasive on the wheel's surface cuts a small chip from the workpiece via shear deformation.
They can be used to help quickly remove excess materials from a workpiece, smooth metal joints after welding or remove paint and primer. Models are available for heavy grinding, chamfering, deburring, cutting and sanding applications, as well as cleaning tire molding, porting, and general high-speed polishing and grinding in confined areas.
That seemed quite low to me, and it let me to wonder what is the "typical" speed at which these grinders run. These were 6" wheels and my grinder spins at 4000 rpm. I have a VFD on that machine and it would be a 30 second process to simply adjust the speed down if I wanted to use those wheels, but instead I let them go.

Dec 15, 2016· 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.
In the case of variable speed machines the number of revolutions per minute (RPM) may be increased as the diameter of a wheel is reduced through wear, provided the original surface feet per minute (SFPM) is never exceeded (the speed table in section 10, table 35, will be helpful in converting RPM to SFPM, also see section 1.2.88, page10).
