Main structure and functions
M1420/HZ universal 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 motor power of the wheelhead is 4kw. 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 workpiece,
the max. weight of the workpiece can be up to 50kg. The workhead motor adopts
variable frequency and stepless speed regulation motor with power of 0.75Kw.
The table consists of swiveling table
and table saddle which can be used to adjust the taper of the workpieces, 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.
