Problem Possible Cause Solution
Workhead base
does not float
Insufficient air pressure Set air pressure of supplied line should be
minimum 85 PSI ( 6 Bars)
Clamping plate does not drop
when unclamped due to less
clearance between upper
floating base and ball bearings
mounted on clamping plate
Take the workhead to one end of the of the
upper floating surfaces (Left or Right side)
float the workhead and pull it against the front
on the T Slatted guide surfaces, then loose
the set screws of the eccentric pin to increase
clearance by using a feeler gage of 0.008” to
0.010” (0.20mm to 0.25mm) in between the T
slotted guide surfaces of the upper base and the
eccentric ball bearing; (see fig. below)
Lock the setscrews, remove the feeler gage
and inspect if is with the tolerance across the all
surfaces.
Repeat if it is necessary.
Clamping plate does not drop
when unclamped due to the
improper adjustment of the
four clamping bolts
Adjust nylock nuts to set he correct clearance
between the bottom side face of the locking
T-Slot of the floating base (Riser) and the top
part of the clamping plate. They are two on the
SG7. The dropping clearance when is on the
floating mode should be 0.015” (0.38mm)on all
the four corners of the workhead clamping plate
