China Factory M2120A Internal Grinder Grinding Machines

Product Description

PRODUCT DESCRIPTION There are many different of finishing processes that are valuable in the production of small metal parts. Typically deployed at the end of manufacturing, these processes include methods of high precision internal grinding.

Convenient grinding operation
All the grinding motions, "from rough grinding, dressing, finish grinding to spark out", are fully automatically operated. This provides high accuracy, convenient operation and greatly upgrades productivity. Also, it is excellent for mass production as well as small quantity, flexible workplace grinding.
The precision workhead spindleThe workhead spindle runs on a high precision roller bearing featuring high accuracy, high rigidity and silent running. The workhead can be swiveled at clockwise 7° ~anticlockwise 8°, allowing for grinding tapered workpleces.

The slide tableThe slide reciprocating movement is driven by a hydraulic system, providing variable speed change and superior stability.
NC controlled auto. dressing with compensationIn case a diamond or CBN grinding wheel is applied, a selection of no dressing compensation is available. For hard-to-grind parts, a multiple dressing compensation mode can be selected to ensure the desired grinding quality.
