13. Start the wheel head.

16.Start the coolant pump, using only a “trickle” of coolant for spin grinding.

17.Begin the spin grinding operation. Grind the reel until the leading edge has a square and sharp edge. For best results, infeed the wheel at 0.001” (one tooth per stroke). See the following instructions to set the auto infeed indexing ratchet wheel.

Indexing The Ratchet Wheel

The ratchet wheel, located just behind the hand wheel, is used to automatically index the amount of “in-feed” of the wheel head. Figure 3-12

CAUTION

PROLONGED CONTACT BETWEEN THE STONE AND REEL MAY CAUSE THE STONE TO CHIP OR BREAK APART, CAUSING SERIOUS INJURY TO THE OPERATOR. DAMAGE TO THE REEL MAY ALSO RESULT.

14.With the carriage in the center of the reel, care- fully adjust wheel head “in” toward reel until slight contact is made. Manually move grinding car- riage left and right. If excessive vibrations or loud grinding sounds occur, quickly adjust wheel head “out,” away from the reel or press the “master kill” button. Check mounting brackets, reel bearings, etc., to make sure all are secure.

NOTE

Sometimes reels wear in either a concave or convex fashion. If the grinding wheel makes contact with the reel only in the center it indicates convex wear. Set limit stops so wheel head travels just beyond points of contact. Read through the following steps, then grind reel until contact is make throughout wheel head’s range of travel. Repeat step 15. If no contact is made beyond points just ground, move limit stops out slightly and regrind. Continue this procedure until contact is make throughout entire length of reel. If wear is concave, reel will have to be ground at each end. Set limit stops as indicated by step 6 and grind until contact is make throughout entire length of reel.

15.If the results of step 14 are satisfactory, engage and start traverse.

Engaging Traverse

5100 Series—Traverse engage lever is located on the left side of the carriage plate. Move it to the cen- ter position.

Ratchet Wheel

Figure 3-12

The amount of “in-feed” per traverse cycle is set by adjusting the screw on the center limit stop. One, two or three teeth can be indexed, infeeding the grinding wheel 0.001, 0.002 or 0.003 inch per traverse cycle respectively.

IMPORTANT

For reels, only 0.001 inch per traverse cycle is recommended by the manufacturer.

NOTE

The distance of travel will vary slightly with the speed of travel. The carriage will “overrun” the return stop if the speed is in- creased without readjusting the screw.
