Lapping machines
Lapping with EFCO lapping machines
EFCO lapping machines are designed for the precision machining of safety valves, ball valves, compressor valve disks etc. We are manufacturers of portable and stationary lapping machines.
Lapping is one of the fine or ultra-fine machining processes with which high surface qualities, extreme shape accuracy and tight dimensional tolerances can be achieved.
Lapping is defined according to DIN 8589 and means machining with loose grain distributed in a liquid or paste. This lapping mixture is located between the workpiece and a lapping wheel. As lapping does not usually involve heating the lapping piece, deformation is ruled out. Many of the EFCO sanding machines can be used with lapping accessories for the precise finishing of surfaces. They are complemented by a range of special machines for lapping.

Questions and answers about lapping machines and lapping
What are lapping machines?
Lapping machines are special tools for processing sealing surfaces. They ensure extremely smooth and precise surfaces by removing material with an abrasive paste. This is particularly important for valves, flanges and other components that need to be absolutely leak-proof.
A lapping machine is mainly used in industry when maximum precision is required. For spherical sealing surfaces, there is the rotago ball lapping machine, which produces an exact grinding pattern. With this technology, even the smallest unevenness can be evened out.
Companies that need a solution at short notice can also use modern lapping machines via our rental service. This gives you access to precise technology without having to invest directly. Whether you buy or rent, our machines stand for top quality and reliable results.

What is lapping?
Lapping machines are used to produce extremely smooth and precise surfaces. During lapping, the workpiece is treated with an abrasive paste. The material is removed in small quantities so that minimal unevenness is evened out.
A lapping machine can be used to perfectly match sealing surfaces on valves, flanges or gate valves. An exact surface is particularly important in high-pressure technology. The rotago ball lapping machine is specially designed for spherical sealing surfaces. It ensures absolutely even material removal and maximum precision.
Lapping technology is used in industry wherever maximum tightness is required. Customers who purchase our durable lapping machines benefit from precise technology and easy handling. This allows components to be reliably reconditioned and optimized for demanding applications.

What lapping tools are available?
Lapping machines require high-quality lapping tools in order to achieve precise results. There are different variants depending on the application. Classic lapping wheels are made of metal or ceramic and are combined with abrasive pastes. These ensure even material removal and a smooth surface.
The rotago ball lapping machine, which was specially developed for these requirements, is suitable for spherical sealing surfaces. It enables particularly even processing. There are also manual and machine tools that can be adapted to suit the component and material.
If you need a solution at short notice, you can use the latest lapping machines flexibly via our rental service. This allows demanding work to be carried out precisely without having to invest directly in a new lapping machine. The focus is always on quality, efficiency and precision.

What is a lapping table used for?
Lapping machines ensure precise surfaces, but a lapping table is the ideal solution for smaller components. It is used to make the sealing surfaces of valves, flanges or other metal parts flat and smooth. The use of abrasive pastes and rotating lapping wheels results in even material removal.
A lapping table can be used both independently and in combination with a lapping machine. It enables precise guidance and facilitates the processing of small workpieces. If you want to remain flexible, you can test various systems via our rental service before making a long-term decision.

Which materials are processed with a lap machine?
Lapping machines are used to process various materials with the highest precision. They are particularly suitable for metal, ceramics and special plastics. These materials must have extremely smooth surfaces in order to function reliably in valves, sealing systems or machine parts.
High-alloy steels and stainless steel can be processed with particular precision using a lapping machine. Hardened surfaces also benefit from this technology, as the smallest irregularities are evened out. Ceramic components used in high-pressure applications are given their optimum shape by lapping.
Different abrasive pastes and lapping wheels are used depending on the material. If you need to process different materials, our lapping machines can be flexibly adapted. We also offerrental for short-term projects. This allows you to use the latest technology without having to invest directly. Precision and efficiency always come first.
