SG90MTS the most versatile machine in the Rottler Seat and Guide machine lineup. The Rottler SG90MTS represents a pinnacle of innovation in modern seat cutting technology. New to this type of machine is the Rottler patented Uni-Pilot tooling technology which allows the operator to move hole-to-hole while cutting seats without the need of re-positioning the pilot or using multiple pilots to process a cylinder head.

Insert Sharpener Operation The Rottler sharpening can re-condition inserts to a finish almost identical to new. The grinding wheel is designed to provide a very fine lapped finish across the entire face of the insert. It should be noted that the grinding holder is deigned to accept RCA/RCB inserts on one side and the larger formant RCC inserts on the other.
Section 4: Operating Instructions SG90MTS Operations Manual Check the insert as you grind it to make sure that it is cleaning up uniformly, also make sure that the set screw does not contact the grinding wheel. When done properly the insert face should look like the image...
Section 4: Operating Instructions SG90MTS Operations Manual Mounting Cylinder Heads 360 Degree Rollover Fixtures The 360 Degree Rollover fixture is a "clamp-up" design which allows for precise deck height location that results in the ability to achieve equal seat depth when cutting valve seats. The design also allows for easy loading and unloading by rotating the fixture 180 degrees to load the cylinder head deck side down.
Section 4: Operating Instructions SG90MTS Operations Manual Alignment and Setup Alignment and setup applies to both the cylinder head and the machine’s floating head. The goal is to align the centerline of the spindle with the centerline of the valve guide. This is achieved by using Rottlers uni pilot tooling system in conjunction with floating the work head, to position the valve seat cutter directly above the seat and centered on the guide geometry.
Section 4: Operating Instructions SG90MTS Operations Manual Canted Valve Cylinder heads (Automotive Application) An optional alignment bar is available that helps establish the front to back alignment on canted valve cylinder heads. The bar is held against two pilots in two adjacent guides. Use the alignment post to adjust the front to back angle of the work head.
Multi angle valve jobs can be completed with ease by utilizing Rottler carbide inserts with desired geometry to create the seat profile. Consult the Rottler Insert Profile Catalog for more information on available seat geometry. Custom seat profiles may also be ordered by request through Rottler manufacturing.
Section 4: Operating Instructions SG90MTS Operations Manual Grasp brass frame in middle of gauge and move upward approximately 1/8”. The dial pointer should move as this is done. Center the pointer of the indicator pointing upward and lock the gauge to the pilot using the brass locking screw.
Section 4: Operating Instructions SG90MTS Operations Manual Fine Feed Engagement To engage the fine feed mechanism it is necessary to push inward on the spindle handwheel while rotating the fine feed knob until engagement is achieved. To disengage the fine feed simply pull outward on the spindle hand wheel.

The unique straight to tapered section shank design, allows for a precise interference fit within the guide to created chatter-free cutting with accurate CONCEN results. Furthermore by using the UPT tool-holder and active spindle system. Rottler machines are able to provide these accurate results while offering hole-to-hole machining all with one pilot.
SG90MTS Operations Manual Shank Diameter The part of the pilot that fits inside the tool holder is referred to as the shank. Rottler offers three different shank sizes (6.00mm, 9.52mm, and 20.00mm). For longest tool life and best seat cutting results, the shank needs to go as far as possible inside the tool holder when cutting valve seats or boring out valve seat housings.
Section 4: Operating Instructions 4-16 SG90MTS Operations Manual For high volume applications, it is recommended to have multiple UPT holders assembled and setup with cutting tools to allow for quick changeover between cylinder heads and different seats. How to Use UPT Series Uipilot Toolholders 1.
