Center Less Grinding Machine PMT-MG C100
Machine Bed:
The Machine bed is
of one piece, close grained, graded cast iron. Box structure design,
heavily reinforced with ribs, provides high rigidity and stability.
Grinding Wheel Head:
Grinding wheel head
of sturdy design is fixed to the machine bed. Wheel head spindle is
made of special alloy steel special heat treated ground and lapped to
achieve high dimensional stability and long life. Spindle runs in
precision white metal bush bearings confirming to SAE 15 which give
very high accuracy and excellent surface finish to the work piece.
Regulating Wheel Head:
Regulating wheel
head is mounted on double slide and swivel plate arrangement (Model
PMT-MG C 100 and PMT-MG-C150). Spindle specially heat treated, ground
and lapped runs in oil immersed precision Anti-Friction bearings to
give high accuracy and true running D.C. Thyristor drive (Optional - AC
variable drive) Provided to get infinitely variable sped of regulating
wheel work piece. Optimum RPM of work piece can be set to achieve hight
production and good accuracies. Regulating wheel head can be tilted in
vertical plane to facilitate through feed grinding.
Infeed System:
In feed is imparted
to the regulating wheel slide through a hardened and ground feed screw,
which ensures high positioning accuracy and repeatability. Specially
designed nut having backlash adjustment is provided. The upper slide
moves the regulating wheel in relation to the work rest for easy bob
set up and lower feed slide is used for feeding work to the grinding
wheel. Work rest base is firmly screwed to the lower feed slide. Work
blades can be adjusted in height on work base for different size of
components.
Taper Correction:
Regulating wheel
can be swiveled in horizontal plane by the swivel plate, for fast and
accurate taper correction and taper grinding.
Automatic Plung Grinding Cycle
(optional):
single lever
operated automatic plunge grinding cycle. Cycle operates as rapid
approach Auto feed spark off rapid retraction and In feed slide moves
to starting position. Amount of in feed, in feed rate and spark of time
are adjustable.
Dressing Unit:
Separate hydraulic
dressing units with infinitely variable dressing speeds provided for
both grinding and regulating wheel (Model PMT-MG C100 and PMT-MG C150)
Profile dressing of grinding and regulating wheel is possible with
special attachment. (Optional)
Hydraulic/Electrical Unit
Hydraulic power
pack unit housed outside the machine for easy maintenance. All
electrical mounted in a concise panel box. Centralized controls for
operator's convenience.
Lubrication:
Centralized
lubrication system provided for efficient and positive lubrication of
moving parts.
