Rottler SG10XY
The Centerline of all valve guides in one cylinder head are not always in perfect alignment. The
SG10XY has the latest design ACTIV Spindle which has a sphere built inside the spindle which
compensates for any misalignment and allows the UNIPILOT tooling system to automatically
center with reference to the valve guide centerline while the workhead is floating on air
cushions. Once the floating stops and the workhead clamps, the UNIPILOT and valve guide
centerline are maintained while the valve seat is cut giving excellent CONCEN. When doing
machining operations other than valve seat cutting such as valve seat housing counterboring
and valve guide reaming, the spindle is required to be locked vertically. The ACTIV spindle has
a pneumatic locking system that locks the spindle sphere rigidly vertically for other types of
machining requirements.
Light Weight Workhead floats on Base Plate
The new design SG10XY has a very light workhead that floats independently on a base plate
allowing precise centering of the pilot in the valve guide. The base plate moves the workhead
from guide-to-guide by a precision ball screw and servo motor. The complete assembly clamps
with air pressure for rigid machining.
Quick X Axis Alignment System
This feature is the secret to productive guide-to-guide
automatic machining! After the cylinder head is clamped
in the fixture, 2 pilots are installed in the outer valve
guides and 2 the alignments arms are moved on linear
slideways inline with the 2 pilots, at this stage, the
complete fixture assembly floats on air and the 2 pilots
contact the 2 alignment arms which aligns the valve
guides with the X axis movement of the workhead. At this stage, the fixture clamps on the machine table, the 2 pilots are removed and the cylinder head is ready for automatic guide-to-guide machining
