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
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.
