Abrasives and lapping agents

EFCO consumables

EFCO consumables are matched to the EFCO equipment through intensive testing. In our abrasives and lapping materials overview you will find all the consumables you need for use with EFCO machines.

Grinding and Lapping Compound Overview

GSS Series

EFCO GSS grinding tools are coated with cubic crystalline boron nitride (CBN) in an electroplated bond.

CBN is ideally suited for grinding hard sealing surfaces with a minimum hardness of 35 HRC such as cobalt and nickel-based steels, high-alloy steels, chrome steel etc.

Only the good heat resistance of CBN in combination with its great hardness enables economical grinding in the range of higher machining temperatures of these steels (long tool life).

EFCO abrasives

EFCO abrasives have been adapted to EFCO technology through intensive trials.

We supply coated abrasives in various grit sizes and designs which are optimised for the respective application.

Abrasive backing: paper, fabric, foil

Abrasive grit: aluminium oxide (Al2O3), silicon carbide (SiC), zirconia alumina (ZrO2+ Al2O3)

Grit size: Standard grit size: P80-P1800 (other grit sizes on request)

EFCOBOR lapping agent

According to DIN 8589, lapping is an ultra-fine machining process with loose grain (lapping mixture) distributed in a liquid or paste, which is guided on a usually form-bearing counterpart (lapping tool).

EFCOBOR lapping agents are oil-soluble lapping pastes made of boron carbide.

EFCO lapping agents can be used to achieve high
