XINXIANG SUNRISE 's center hole grinding machine, is developed by utilizing XINXIANG SUNRISE 's designing philosophy and essences of the manufacturing technique.

2M8015 is a precise center hole grinding machine capable of grinding both center holes accurately without turning the work pieces. Delivery of 2M8015 into the market made a step forward to the future potential of extra precision cylindrical grinding machines. 

    Main structure and transmission requirements of machine

1，The machine guide way needs many times of aging treatment, good abrasion resistance.

2，The grinding shaft components are composed of extremely precise spindle and bearing components. And through a number of aging, flaw detection, processing, assembly and adjustment, and stable work. Spindle box can feed grinding and return.

3，The workpiece clamping mechanism has automatic centering function

4，Wheel dressing mechanism is moving along grinding wheel semiangle generatrix, accurately dressing the wheel cone.

5，The oil mist lubrication is used in the lubrication system, and the oil mist is carry to the workpiece box by the compressed air, to achieve the lubrication of workpiece spindle and bearings.

6，The machine is equipped with a vacuum cleaner, which can realize the synchronization of grinding and dust cleaning.
