Hard Metal Lapping Compound for LAPPING CAST IRON, STEEL and BRONZE

MSDS Data Sheet

Please see Precision Finish Booklet (PDF) or contact us for complete directions for use.

Mix TIMESAVER with oil as you use it and only the amount needed for the particular job to be done. Keep well mixed.

GEAR UNITS - Mix TIMESAVER with heavy oil or grease in proportions of one part TIMESAVER to three parts of oil by volume. It is preferred to protect ball or roller bearings by the use of shields or by covering with grease. It is customary to leave the cover off of the gear case for convenient inspection and application of the lapping compound. Bearing races should be held in place by bolting down with blocks. Relatively heavy brake loads should be applied to insure fi

CAST IRON BEARINGS - mix our Hard Metal Compound with light engine or cutting oil to the consistency of a thin paste. Mixture should be thick enough to stick to the bearings surface. Just before placing the shaft in the bearing, add oil to surfaces in order to thin compound to proper lapping consistency. Bolt up cap - not too tightly, just so shaft can be turned by hand - and proceed to lap. At intervals add compound if necessary. When a full bearing surface has been

CAUTION - Do not use Hard Metal Compound (GREEN Labeled Can) on babbitt, brass, aluminum or bronze. For this work, use our soft metal compound (YELLOW label can). TIMESAVER can be used on any hard metal friction surfaces where accurate fits are required, such as valve seats, machine tool ways, tool room applications, etc.

TIMESAVER COMPOUNDS ABSOLUTELY DO NOT IMBED OR CHARGE INTO ANY METAL SURFACES. Therefore, do not attempt to make a lead, copper or other soft metal lap to lap hard metals, as is done with emery, ground glass, silicon carbide or other similar charging abrasives. The lapping plate should be at least as hard as the surface to be lapped and harder if possible. The softer of the two metals will get the most wear.

We also make SOFT METAL LAPPING COMPOUNDS
for lapping babbitt, brass, bronze, and aluminum.
