CAMPBELL MODEL AS4860-16D 8 AXIS PRECISION UNIVERSAL GRINDER

Worktable
Worktable will be 48" precision table with 8 tee-slots for "full circle"
rotational grinding.
Above unit will provide maximum 60" swing clearance
Rotational model will provide variable speed from 0 to 40 RPM
Grinding Spindles
Reversible precision Pope spindles will be interchangeable for ease of m
aintenance.
The spindle will be precision balanced, and arranged for mounting heavy-
duty wheel
dresser.
Grinding wheel spindle run-out and camming shall not exceed .0002" T.I.R
. with
wheel in place wither perpendicular to the base or set off at any angle.
Spindle design will enable the use of 12" diameter grinding wheels, with
wheel life
to 5" diameter.
Drive motors are 10 HP, 1755 RPM. Optional variable speed was provided.
Grinding Wheel Dresser
Latest diamond roll dresser is of rigid and provides error proof infeed
control
through precision servo motors.
Precise infeed adjustment variable from .0001 to .005"/dress with "pause
" cycle
between feed pulses for optimum dressing performance.
Units will facilitate 1-1/4" stack of 4" diameter diamond rolls.
Dresser will incorporate wheel guard to enclose 180 degrees of grinding
wheel for operator safety.
Positive hydraulic drive for diamond roll spindle.
Horizontal Slides
Electronic servo motor provides positioning control Jog direction is re
versible.
Traverse rate is 40" per minute.

tion)
Preloaded ball crew will be used for accuracy.
Vertical Slides
The vertical slide movement shall be 21"
Traverse rate is 40" per minute
Vertical position controlled by electronic servo motor.
Preloaded ball actuator screws will be used for accuracy.
Angle Slides
Grinding spindle will e mounted to angle slide.
Angle Slides (Cont'd)
Angle slide will have variable feed capability in pulse increments of .0
001"
to 020" per minute , by electronic motor
Automatic sequencing from coarse to fine feed by controller.
Traverse rate will be 10 IPM
Slide will swivel + or 90 Degrees from vertical
Total slide travel will be 6"
Attached dresser will dress wheel during the grind cycle to eliminate dr
essing time.
Automatic compensation will maintain correct zero position whenever dres
s occurs.
Control System (Angle Slide)
Modern programmable Fanuc CNC and electronic motor drives will provide
compact and trouble-free solid state control system.
System will provide precise zero stop function and retract to start posi
tion.
Auxillary positions can be programmed to change feed rate, initiate dres
s, or
whatever other control functions might be desired.
Visual displays will show wheel position from "zero", as well as, horizo
ntal
and vertical slide locations.
