This series machine is suitable for finely and roughly turning cylinder and inner hole, inner and outer taper, surfacing, grooving, threading and curving of the ferrous, nonferrous metal and some kinds of non-metal materials with hard-alloyed and porcelain tools.
This series machine is divided into universal type and CNC type, while CNC machines have standard and heavy-duty types.
The main drive is provided by DC motor by two-step vertical axle speed-changing device to engage in table speed-change.
The table spindle is centered by high-precision double-row short roller bearing whose radial clearance can be adjusted. With constant flow hydrostatic guideway and oil temperature device applied in axial direction, the table has features of higher swivel precision, larger load ability and smaller thermal deformation.
AC servomotors, which drive the ball-screw via rated gear-set to control the heads to feed or rapid move composes machine's feed system.
CNC machine's vertical head adopts constant flow hydrostatic guideway in horizontal direction while the RAM adopts rolling and sliding compound guideway.
On customer's requirement, digital display unit, grinding head of electric spindle can be provided.
The left column and right one are fixed directly on foundation separately instead of connecting with table. This kind construction eliminates the mutual influence of spindle transmission, feed and thermal deformation, which also improve the whole precision and is convenient for precision regulation.
