Three Angle Seat Cutting:
Place the ball drive adapter in the spindle.
Align spindle to valve guide.
Place a valve in the setting fixture. Position the pointer on the
valve where you wish to place the top of the seat.
Remove the valve; replace it with the correct pilot.
Select the proper diameter tool holder. Place the carbide insert in
tool holder. Slide tool holder onto ball head.
Place ball head over the pilot in setting fixture. Use radial
adjusting screw to set diameter of cutter to correspond to position
of pointer on setting fixture.
Tighten hex socket screws on bottom of ball head. See figure 9
Remove ball head assembly from setting fixture. Place fixed
carbide pilot in cylinder head.
Center the spherical ball head toolholder over the pilot shank.
Required spindle rotation speed will vary, depending on seat
hardness. As seat hardness increases, so does the required
spindle speed. Some will require full speed.
Special care should be taken in centering the floating head
above the valve guide, to achieve a concentric seat.
Cut seat only enough to clean up surface.
Too much cutting will sink the valve too far in the head. Many
operators prefer to use the spindle fine feed when machining
seats as extreme control of spindle down feed can be
accomplished.
The capacity of the Rottler SG7 / SG8 / SG80AII / SG9
associated with a complete tooling range allow working on seats of diameters between 14 and 120
millimeters (0.55’’- 4.7’’).
Three tooling ranges are possible:
For seats diameters between 14 and 25 mm ( 0.55’’- 1’’): tool holder BH600R1 and Mini tip holder
TH1999 for seat range .551" - .984" (14mm-25mm) with pilots with 6.00mm shank diameter.
For seats diameters between 18 and 60 mm ( 0.71’’- 2.4’’): tool holder BH375R1 and tip holder
TH2000 for seat range .710" - 1.180" (18mm-30mm) or TH2001 for seat range 1.100" - 1.570" (28mm-
42mm) or TH2002 for seat range 1.570" - 2.360" (40mm-60mm), with 9,52 mm ( 3/8 ’’) pilots of shank
diameter
For seats diameters between 40 and 80 mm (1,570”- 3.150”): tool holder BH375WR1 and tip holder
S2003N for seat range . 1.570’’ - 2.360’’ (40mm - 60mm) or S2004N for seat range 2.280" - 3.150”
(58mm - 80mm), with pilots with 9,52 mm ( 3/8 ’’) shank diameter.
IMPORTANT: When the form tips, the square tips or the triangle inserts are fitted, check that their
reference faces are perfectly clean.
