Automatic Screw Machines And Tooling
This is representative of a series of automatic screw machine tool
holder designs created for the Brown & Sharpe PTC and Ultramatics.. Indexable
insert technology was integrated into the newer designs. There also are several
interesting cross-slide designs for cutoff, circular form and dovetail form tool
holders. Designs range from some interesting cross-slide actuated profile and relief
boring turret tool holders to the mundane stock stop.
The bed casting for the Brown & Sharpe #2 Ultramatic was redesigned to
accommodate more recent advancements in sand casting.
|Grinding Machine Spindles
These are antifriction bearing grinding machine spindles designed for the Brown
& Sharpe 618 surface grinder. They are kingpost designs using preloaded class 7
angular contact bearings. Each design features a labyrinth seal at the wheel end and
is dynamically balanced as an assembly. The motorized version features a rotor fit
on a taper on the tailshaft.
Several generations of process tooling have been designed for assemblies
and details. Tooling has been designed for the Disk Drive, Medical Instrument,
Semiconductor Process Equipment, Machine Tool and Linear Motor industries.
Propeller Blade Surface Measuring Machine
This was designed for a west coast shipyard for installation by a valley
firm that has now been literally reduced to rubble. It is included to show the
richness of the industrial landscape we once enjoyed.
The design is a scaled up Portage-style measuring machine with two
arms. Each counterweighted arm is actuated by a recirculating ballscrew driven by a
DC servomotor with feedback provided by an inductive (Ferrand) linear encoder. The
horizontal axis was likewise actuated via a ballscrew drive with feedback provided by an
inductive linear encoder.. Measurement heads composed of LVDT probes were mounted at
the end of each spar.
While the designs on
this page represent functioning products, several details in each case have been deleted
or altered to protect the client.
