Main structure and functions
M1320/HZ external cylindrical grinding machine is designed for
grinding rotary parts of cylinder and cone with diameter less than
200mm.
The wheelhead adopts integral structure to improve the rigidity,
the design of wheel spindle ensures the processing accuracy and
realizes high strength and rigidity, thus to achieve
high-efficiency grinding requirements. The wheelhead spindle
bearing adopts two sets of sliding bearings which composed of three
bearing bushes, featuring high rotary precision, high rigidity,
good resistance to vibration as well as heavy-load and heavy
plunge-cut. The spindle bearing lubrication oil is supplied
directly by the oil sump, with self-lubrication protection function
and easy for maintenance.
The cross movement of the wheelhead is provided with hydraulic
rapid advance and retract function.
The taper of workhead and tailstock adopts Morse 4#, which greatly
improves the bearing rigidity of the workpieces, the max. weight of
the workpiece can be up to 50kg.
The table consists of swiveling table and table saddle which can be
used to adjust the taper of the workpiece, it is positioned through
locating pillar and pressing plates at both ends. When the
swiveling table needs to swivel for a certain angle, the angle
&#118alue can be measured by the scale. Micro-adjustment can be
measured by the dial gauge. The table guideways use flat-V and
plastic sliding guideways. The guideway surface adopts hand
scraping. The longitudinal movement of the machine table can be
hydraulic-driven and manual-driven, lubrication adopts small-hole
throttle unloading type.
All movement components of the machine adopts electrical, hydraulic
and mechanical interlock mechanism, the rapid advance and retract
movements adopt independent handle, thus to make the machine easy
to control and safe to operate.
