Normac CL20


Automatic loading system for retrofit on centerless grinders and other machines.

The CL20 is basically Normac's patented box hopper loading system with electrical and hydraulic
controls necessary for automatic operation.

Specifications:

Diameter Range:
.040 to 1/2" (1 mm -13 mm).

Overall Length: 1.6" to 8" (40 mm - 200 mm).
Straight cylindrical parts only.

Cycle Time: Average 2 to 4 seconds.

Normac CG20



Intended for retrofit applications on through feed
centerless grinders. This device is used for grinding back taper on drill blanks. After the shank end of the
blank has been pushed past the outside of the grinding wheel, the CG20 tips the blank up and out of the grinding
area, leaving the cutting end of the blank with the back taper dressed into the grinding / regulating wheels.
The CG20 is mounted to the exit end of the blade rest area of the centerless grinder.

Specifications:

Diameter Range:
.040" to 1/2" (1 mm - 13 mm).

Overall Length: Up to 8" (200 mm).

Automatic loader assembly is basically the same as Model CL20 but has extended length
capability up to 12" (300 mm) overall length.

Very similar to Model CL20, but instead of a box hopper, the CL40 features a
magazine style loading arrangement.

Normac TCW-75E


Automatic center type relieving workhead assembly is for retrofit on existing external or surface grinders,
and can be used for relief grinding of router bits and other tools, cam grinding, and other cylindrical relief
grinding applications. TheTCW-75E features a permanent master cam with a micrometer adjustment for rate
of relief. Change gear blocks are used to enable grinding 1, 2, 3, 4, or 5 lobes. The TCW-75E is
designed for dead center grinding with a hydraulically operated quill for opening the centers, and drive
dog concentric with the quill for part or arbor rotation.

Automatic radial/axial relieving workhead is very similar to Model TCW- SRX but has a unique clutching
mechanism to orient the relief cams after radial location of a flute or other part feature. This workhead is
particularly well suited to full automation projects for relief grinding.

Very similar to Model TCW-75E but has an additional axial relief motion. Axial relief is provided by an interchangeable
cam with relief rates up to .072" (2 mm).
