or work surfaces.

Air Filter

Device for removing contamination

from air supply lines. Typically refers to

removal of particulates.

Burr

Any unwanted, raised protrusion on

the workpiece.

Chuck

Gripping device used to hold tools and

media to the spindle.

Compliance

The ability of the spindle to passively

move in response to protrusions on or

deviations of the work piece.

Forward Sensor

The forward sensor is an inductive prox-

imity switch which is ON when the spin-

dle is in the fully extended position indi-

cating there is no contact with the tool.

Gearhead

A gearbox responsible for reducing the

spindle speed of the air motor.

Main Housing

The main cylindrical body of the unit

which includes the mounting features.

Media

Term referring to tools and/or abra-

sives held by the tool during the com-

pletion of a manufacturing process.

Rear Housing

Rear cover to the main housing. This

body includes a connection port for the

compliance air supply and feed-through

seals for optional electrical sensors.

Regulator

Device used to set and control the sup-

plied air pressure to lower acceptable

levels.

Retract Sensor

The retract sensor is an optional induc-

tive proximity switch which is ON when

the spindle is in the fully retracted po-

sition indicating there is no further mo-

tion possible.

Solenoid Valve

Electrically controlled device for

switching air supplies on and off.

Spindle

The rotating portion of the tool assembly.

Tachometer Sensor

The tachometer sensor is an optional in-

ductive proximity switch which monitors

tion. It is recommended that the tacho-

meter sensor be utilized for process de-

velopment but removed from the unit

when in a production environment.
