Ville Swiss, established in 1985, is a manufacturer of proprietary machined metal
products for corporations.
We utilize a block of "Sliding Headstock" machinery that is comprised of Citizen and
Tsugami CNC's, Tornos Swiss cam machines and Escomatic coil fed cam machines.
The key to understanding our identity lies in the term "Sliding Headstock." This type
of automatic equipment is ideal for holding tight tolerances on our products due to the
tooling being mounted close to a very accurately bored, adjustable bushing. The machinery
then uses a headstock to "Slide" the material through the bushing into the tooling.
Because the bushing keeps the material very rigid at the point of machining, the machinery
is capable of holding tolerances as close as +/-.0002 on diameters, under ideal conditions.
The concept makes the sliding headstock machinery ideal for the manufacture of long slender
parts, typically where the length of the part exceeds three times it's diameter.
There are other advantages to the sliding headstock machinery. On the cam type machinery
we are able to stop the spindles and on the CNC type machinery, we enjoy complete, 360
degree, control of the spindle rotation. On the cam type machines we are able to stop the
spindle to machine operations such as cross-drilled holes, mills and slots, and broached
forms. On the CNC controlled machines, we are usually limited only by imagination as to
what we can accomplish in part configuration.
There are weaknesses in the sliding headstock machines that make them non-competitive in
certain part configurations. The bushings tend to generate friction under heavy load,
thereby limiting the speed at which the tooling can remove material from the barstock.
The machines also do not typically possess the horsepower that conventional type machinery
may have. Therefore, if you can sacrifice some dimensional accuracy and repeatability for
high production rates, the sliding headstock machines may not be able to compete with
certain types of conventional machinery as related to pricing, but if you want close
tolerance, repetitive dimensioning and the elimination of "Secondary operations" sliding
headstock machines are the perfect candidates.
