Secondary Operation Machines
FORMING . SLOTTING . DRILLING . MILLING . FLATTENING . TAPPING
The machines described here represent advanced design in modern second operation machines based on principles developed in the first tonsils Townsend Machines in 1910 , and consistently refined ever since.
Today, we offer complete solutions to many machining problems . There are four basic machine sizes, each with many optional features in attachments . The high speed machine and number 2 Machine are preferred for most applications , since they have the capacity for the widest range of parts in the more common sizes.
Every Townsend machine features automatic feeder and parts injectors… a main drive including positive mechanical cams and linkages, so that all motions are interlocked and sequenced most sufficiently. Auxiliary controls in complex circuitry are not required . Other advantages are automatic chucking interchangeable spindles and easy tooling .
