- The Steiner KA Autofacer is a modular semi-standard front and back counterboring system that was designed for machining seat pockets and clearance bores in Gate Valves
- The KA Autofacer utilizes expandable bushings and modular dampeners to support the tool when cutting which eliminates the need to hold a tight diameter tolerance on your flow bore
- Our modular connection allows lengths to be built out in 6” and 12” increments.
- The KA Autofacer can be used on standard CNC machine tools- No “W” axis is required.
Technical Benefits
- Weld variation does not affect the manufacturing
process - Utilize same bushings as current contouring heads
- Rough in one pass
- Much stronger design
- More stable process
- W axis machine is not necessary for running KA Autofacer
- Significantly less expensive than contouring heads
- Does not require machine to have W axis
Machining on Vertical
Turning Lathe
- Utilizing a VTL to machine these valves can be
very cumbersome and often involves 3 or more
setups to machine all required features - The customer will need to purchase multiple
sizes of offset boring bars to reach out to the
required seat pocket and clearance bore
diameters - The unsupported tooling typically requires
slower speed and feeds - This will usually result in a rougher surface
finish
Modularity
- Utilizes high precision boring connections to
be able to build out lengths to suit part
needs - Modular components are standard
- Standard tool sizes from Ø2” Ø7” valves
- Spring loaded dampener reduces vibration in
tool body when cutting
