Lapping is a machining technique that is used to produce precision finishes on machined parts. Lapping can be used to produce a very flat surface, flat lapping, or to produce good fitment between two mating components, i.e. gear teeth, shaft and bushing, shaft and bearing, piston and cylinder, etc.. Timesaver Lapping Compounds are typically used in precision fitment between mating components as it breaks down too quickly to be an effective medium in flat lapping procedures. The abrasives in Timesaver Lapping Compounds are designed to produce a precision finish and fitment between two components without charging into the metal or continuing to cut.

The abrasives in Timesaver Lapping Compounds are designed to produce a precision finish and fitment between two components without charging into the metal or continuing to cut.

Timesaver Lapping Compounds come in two different grades;

  • Green Label Grades for ferrous metals (steel, cast iron, hard bronze and stainless steel)
  • Yellow Label Grades for non ferrous metals (Babbitt, brass, bronze and aluminum)

Types of Lapping:

The decision of which lapping compound to use is determined by the base material to be lapped. Timesaver works opposite of most lapping compounds. Lapping compounds containing aluminum oxide, silicon carbide and similar charging abrasives use a lap that is softer than the pieces requiring lapping. With Timesaver, the softer of the two mating pieces will see most of the lapping/cutting action. However, Timesaver Lapping Compounds will not charge into the metal, reducing or eliminating the need to disassemble the work pieces, eliminating the need to clean the parts prior to changing grit size, and reducing the time required to remove the lapping compound once the procedure is complete. Simply flush out the lapping compound with solvent or clean oil.

Benefits of Timesaver Lapping Compounds:

  • Produce precision finish.
  • Reduce disassembly and reassembly time because Timesaver comes in powder form, use only the amount needed with your own inexpensive carrier.
  • Timesaver Lapping Compounds will not charge into any metal surface or continue to cut, they first act as a quick cutting abrasive, diminish to a polish and finally to an inert material.
