Main structure and functions
M1432/HZ universal cylindrical grinding
machine is designed for grinding rotary parts of cylinder and cone with
diameter less than 320mm.
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 four 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, manual micro-feed
function and grinding wheel auto-cycle feed 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 150kg. The workhead motor adopts
variable frequency and stepless speed regulation motor.
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.
