Troubleshooting
Eccentricity Problems when Cutting Three Angle Seats
:
Spindle floated to improper center location.
Excessive pressure when forming seat.
Incorrect spindle speed.
Worn or improperly selected pilot.
Worn Valve Guide.
Workhead base
does not float
Concentricity is
not with in the
tolerance
1- Insufficient air pressure
2- Clamping plate does not
drop when unclamped due to
less clearance between
upper floating base and ball
bearings mounted on
clamping plate
3- Clamping plate does not
drop when unclamped due to
the improper adjustment of
the four clamping bolts.
1- Set air pressure of supplied line should be minimum 85
PSI ( 6 Bars)
2- 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.
3- 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 [art of the clamping plate. They
are four clamping bolts on the SG8 and 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
