Machine Tools

The grinding machine includes a power driven grinding wheel(abrasive wheel) spinning at the required speed (decided by the wheel’s diameter and manufacturer’s rating, usually by a formula) and a bed(without bed for centerless grinding machine) with a fixture to guide and hold the workpiece. The grinding head can be controlled to travel across a fixed workpiece or the workpiece can be moved while the grinding head stays in a fixed position. Very fine control of the grinding head or table’s position is possible using a vernier calibrated hand wheel, or using the features of numerical controls.

Headstock: The headstock is the powered end and is always at the operator's left. This contains the speed changing gears and the revolving, driving spindle, to which any one of several types of work holders is attached. The center of the spindle is hollow so that long bars may be put through it for machining.

Pay attention to below items:

1)       Feed drilling bit towards face, the power can’t be too big, in case to break drilling bit and hole misregistration.

The choice of diameter of milling tools is decided by milling machine itself and milling dimension of workpiece.

1)     Face milling tools

The most important factor when choose face milling tools is the power should be within the power of milling machine, and it also can be determined by the diameter of spindle. Diameter of milling tools D=1.5d(d is diameter of spindle). For large quantity producing, the diameter of milling tools could be 1.6d.

CNC machine tools offer precision machining to all works. No matter what kind of CNC machine tools being used, it can pretty much guarantee that it will offer precision machining that is absolutely unbelievable.

CNC servo motors must be able to provide the customers with the highest possible performance standards and with the best quality while still being reliable. Because of the type of machining that CNC machines can perform it is essential that the motors can stand up to the performance standards that are required.
