The portable Rocklinizer allows you to easily boost wear prevention, gripping, and maintenance in your plant.

The Rocklinizer Applicator is automatically triggered when the electrode is placed in contact with the workpiece, or manually triggered by the operator. Deposits are available from .0001" to .010" and higher in a single application, controllable within .0001" by machine setting. Typical deposits are obtained from Rocklinizing hardened tool steel.

The Rocklinizer electronically applies electrode material by a proven spark deposition process. Material is impregnated both underneath and on top of the workpiece surface. Because no appreciable heat is generated, the temper of the workpiece is retained. Rocklinizing is applied to new or reground and resharpened surfaces.

Drills

METHOD #1: Apply to sharp drill. Deposit between .0003" and .0005" inside flute, on end at cutting edge from land to point, and on land from corner up 1/4". Apply between .0005" and .001" behhind edge where chip load occurs. For drilling abrasive materials, apply deposit the entire length of the drill.

METHOD #2: Apply to dull drill. Deposit between .0005" and .002" inside flute only, for 1/2" to 1" of length. Then sharpen. Re-apply after several resharpenings.

Taps

METHOD: Apply to sharp tool. Deposit .0002" to .002" in flute from point to first or second full thread as shown. Apply carefully with side of electrode to avoid striking cutting edges. Re-apply after re-sharpening. Deposit between .0003" and .0005" directly behind cutting edge. For tapping abrasive materials, apply the deposit all the way up the flutes of the tap.

Chasers

METHOD: Top edge, similar method for Taps.

End Mills

METHOD: If tool is sharp, deposit .0003" to .0008" inside flute at bottom edge and side edge for length of tool, being careful not to strike edges. If tool is dull, use same procedure, except deposit can be between .0005" and .001" and tool is then ground.

Reamers

METHOD: IF sharp, apply inside flute only with deposit of .0001" to .0008". Apply carefully to avoid striking or rubbing edge. It is then best to hone any of the outside land slightly wherever size is not affected. Occasionally a .0003" deposit on the outside land before honing is also beneficial. If dull, use similar procedure, except grind tool after deposit is applied in flute.

Milling Cutters & Thread Cutters

METHOD #1: Apply to sharp tool. Deposit .0003" to .0004" on face of each tooth along edge being careful not to strike edge as tool is used without further regrinding untill dull. Deposit between .0004" and .0008" (.002" for severe jobs) at edge.

METHOD #2: Apply to dull tool. Deposit .0005" to .001" on face of each tooth along edge as shown. Wide deposit will be suitable for several regrinds. Then grind land to sharpen edge same as Method #2 for Drills.

Hobs

METHOD: Use Method #1 for Milling Cutters. One or two very light stone passes on outside tooth from edge will remove any buff.

Punches, Dies & Shears

METHOD: Apply to the area which is getting the wear. This can be at the sides or on the face, or it can be at both positions. Usually, for most types, the deposit is made on the sides, and then the face is ground. In this manner, worn areas can be built back to size without cutting away the entire worn portion of the punch or die. Deposit can be from .0003" to .001" for wear resistance only, or .0001" to maximum for build-up. Sometimes, deposit is made on face. For best results, experiment with deposit location and amount.

Tools Bits

METHOD #1: Apply to sharp tool. Deposit between .0003" and .0005" along top edge, and along front and side, for protection of both sides of cutting edge. Apply between .0003" and .001" directly behind the light deposit.

METHOD #2: Apply to dull tool after back rake is ground and before front and side are ground. Deposit .0005" to .002" along front top at edge. Then grind front and side. If back rake is not re-ground at every re-sharpening, one wide deposit may last through several re-sharpenings.

Cutoffs

METHOD: Use Method #2 for Tool Bits, with deposit between .0003" and .0006". Do most of the top area at first application, adn each re-grind will renew edge.

Carbide Inserts

METHOD: Follow carefully techniques for applying Titanium Carbide with Super Titan Electrode. Use methods set out for application to each type of tool set out herein.

Form Tools

METHOD: Apply to sharpened tool. Deposit only .0001" or .0005" on top along edge. Apply carefully with side of electrode to avoid striking or rubbing the cutting edge or corners. Deposit between .0004" and .0006" at edge. Then hold a fine stone on front face of tool and make two light and short passes to remove any burr left by deposit at cutting edge.

Broaches

METHOD: Apply to sharp tool, deposit .0003" to .001" on face of cutting side of each tooth. Be careful not to strike edge. Alternate methods: Use Method #1 or Method #2 for Milling Cutters.

Saws

METHOD: Apply to sharp saw. Deposit between .0002" and .0006". Apply to front and top edges of tooth. On some saws, especially thin ones, deposits on sides of tooth are also helpful. On saws with very small teeth, the side deposit is the only method, and teeth are sharpened after deposit, not before.

Knives

METHOD: Apply to sharp knives. Deposit .0002" or .0005" on both sides of edge, being careful not to strike or rub edge. In some cases, knives can have deposit applied at one side of edge only, and other side can be honed.

Collets, Chucks

METHOD: Apply sufficient deposit to maintain desired dimensional tolerance and to provide appropriate gripping surface. Collets, pads and leed fingers may be protected from wear.

Seaming Chucks and Rolls

METHOD: Apply minimum deposit to new seaming chucks and rolls without exceeding tolerances. On worn seaming chucks and rolls apply sufficient deposit to build up and restore tolerance and prevent "spinners" in the production line.

Bearings

METHOD: For bearings loose on a shaft or outside housing, apply electrode material on holding surfaces sufficiently oversize so that when bearing is pressed back on shaft or in housing a firm bond to mating surface is achieved.

Machine Surfaces

METHOD: Apply over entire area. Deposit range is from .0003" to maximum, with heavy deposit on areas of greatest wear. Experimenting is required to determine best amount. For greater smoothness, use fast side-to-side motion, apply heavy coat, then go over with a lighter coat. (Example: if .002" is heavy coat, .0003" would be the light coat) For more smoothness, stone or tap lightly, after the light coat. It is not necessary to remove remainder of previous deposit when applying re-coat.

Die Casting Dies & Cores

METHOD: Apply to metal surfaces which come in contact with hot metals. Be sure and coat gates with heavier Rocklinizer electrode deposit of .002". On cores apply .0003" to .0005" on areas where draw is made. Sometimes Rocklinized cores draw better than highly polished cores. Rocklinize heavier coatings on areas which tend to solder to dies.
