A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().

The specialist for highly precise roll machining designs, manufactures and delivers roll grinders, lathes and roll shops, including automation.

Centerless grinding machines are often classified according to the inclination of the machine bed. Horizontal-bed machines are the most common, as they provide easy accessibility during wheel dressing. Angular and even vertically inclined beds are used for grinding heavy workpieces because of the potential for a greater grinding force and less abrading of the workpiece by the work support.

Grinding, or abrasive machining, once performed on conventional milling machines, lathes and shapers, are now performed on various types of grinding machines. Grinding machines have advanced in design, construction, rigidity and application far more in the last decade than any other standard machine tool in the manufacturing industry.

Shoe grinding is a variation of centerless grinding. Using a magnetic plate to support the wokpiece axially while driving the blank along with a set of precision rollers (shoes) that support the wokpiece radially, shoe grinding enables both ID and OD surfaces to be ground in a single setup.

grinding machines perform the dressing task automatically. The application of coolants to the grinding process is important. Coolants reduce grinding machine power requirements, maintain work quality, stabilize part dimensions, and insure longer wheel life. Coolants are either emulsions, synthetic lubricants or special grinding oils. Coolants are applied by either flooding the work area or by ...
