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
