PALMARY technical breakthroughs - the NC series internal grinding machines - are designed and engineered according to the highest standards. Great attention is paid to every detail of the entire machine. This fully reflects PALMARY's state-of-the-art manufacturing techniques. In addition, the NC series are equipped with a conversational operation interfacing control that makes your internal grinding easier and more accurate.
Convenient grinding operationAll 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.
