An improved solid, one-piece cast
frame enables the Lempco Model TPG
to be attached so rigidly it prac
tically becomes an integral part of
the tool on which it is mounted. The
elimination of vibration thereby
accomplished materially aids in
producing a superior finish to re
quired tolerances.
T
aper
Both internal and external tapers
are ground fast and accurately. Cup
type and recess abrasive wheels for
all kinds of taper grinds are in
cluded in standard equipment.
BALANCED QUILLS
F
Quill assemblies are ground to ex
tremely close tolerances, balance
exactly, and undergo strict inspec
tion
both
statically and dynamically.
The quill is mounted in four pre-
loaded,matched sets of ball-bearings
kept constantly lubricated in a fog
oil bath.

Face grinding with a cup wheel is

The Lempco Model TPG meets this

mercially perfect finishes free from
chatter or pattern on all types of
