Preface
Intended Use Statement
The PCNC 770 is intended for use as a general purpose CNC milling machine. The intended use includes
cung convenonal (non-abrasive) materials such as unhardened mild or alloy steels, aluminum,
plascs, wood, and similar materials (or any other material that can be cut with a rotang cuer).
Outside Scope of Intended Use
Applicaons for the equipment or modicaons of the equipment outside of the Intended Use
Statement are supported through consulng engineering and excluded from Tormach’s no-cost
technical support.
All of the technical informaon and insight required to support variaons from the intended use
cannot possibly be foreseen. If the extensive documentaon provided is insucient, Tormach can
provide addional informaon and engineering support on a consulng-engineering basis. If you
have your quesons well organized, we can normally provide all the informaon you need in short
order. Consulng engineering is done by electrical and mechanical engineers and billed at current
hourly rates.
All warranes for Tormach equipment are voided through modicaon to the equipment or use
outside of the intended use. Individuals or companies involved with modifying the equipment or
applying the products assume all consequent liability.

For standard R8 spindle
PCNC mills are capable of cung any material that can be cut with a rotang cuer at or near their
recommended feeds and speeds. As with any mill, care should be exercised so that programmed
cuts do not exceed the maximum available spindle horsepower. Small diameter cuers may perform
beer with use of a companion spindle or RPM mulplier such as the Tormach Speeder™ (for more
informaon, refer to chapter 8, Accessories).
