A Look into the Innovative and Precise Process of Fine Grinding
11-05-2017

Fine grinding is a finishing process performed by removing a well-defined amount of stock from two parallel flat surfaces of components. This requires extremely precise geometric accuracy and good surface finish. It is typically the last grinding step of a mechanical production chain installed to improve and correct the geometry of parts coming from sintering, sawing, molding or similar operations.

 

A fine grind represents the latest innovation in precision finishing technology, offering several advantages over the traditional lapping process yet still yielding similar flatness, parallelism, surface finish, and size tolerances. The fine grinding process is much cleaner than lapping, and eliminates swarf disposal and work piece cleaning issues. Swarf is material such as metallic particles and abrasive fragments removed by a cutting or grinding tool. A fine grind is also typically 3-20 times faster than lapping, blurring the lines between traditional lapping and grinding technologies.

 

Effective component processing using fine grinding technology requires heavy-duty equipment with sophisticated control systems capable of high plate rotation speeds and down-pressure generation. At Classifier Milling Systems, we offer several new fine grinding machine models available in both single sided and dual faced configurations. This line of equipment has been designed using the latest machine construction and control system technology, capable of executing complex grinding routines while producing precise and repeatable results.

 

Classifier Milling System’s development of fine grinding equipment and processes are bridging the gap between traditional flat lapping and grinding machines, utilizing the best technologies of both. Significant growth is expected in the metal, ceramics, and composites finishing industries where fine grinding offers increased productivity, reduced manufacturing costs, and a positive impact on the work environment.

 

Applications

 

Typical applications of a fine grind are:

- hydraulic pump components (rotors, stators, covers, blades)
- automotive (injectors, piston rings, fuel & diesel pumps components, valve plates)
- bearings
- technical ceramics
- hard metal inserts, knives, sawing blades
- horologer components
- compressors
