Flat Honing and Lapping with Two-Wheel Machines
Application Areas and Future for Two- Wheel Machines
In the refinishing centers of the Stahli Group, the ratio of machining orders for single to two-wheel machines is still 2:1. However, there is a clear trend towards the more frequent use of two-wheel machines, specifically on the basis of diamond and CBN wheels.
The application areas for two-wheel lapping and flat honing machines are principally in the field of the mass machining of flat workpieces. If the machining method is coordinated perfectly, it can achieve an extremely high production rate.
New technologies, such as flat honing on fixed-grain wheels made of corundum, CBN and diamond, combined with a central and/or flood rinse and semi- or full automation have opened up a successful future for the two-wheel machine. With this method, individual work phases can be skipped, which makes the process extremely economical. “Clean lapping” or flat honing is also asserting itself for environmental reasons, and virtually all businesses are now demanding a conversion (cf. Chapter 6).
In conclusion, we would like to state that lapping/polishing and flat honing are sure of a bright future. Flat honing is being acknowledged more and more by the industry as an economical and high-quality procedure. University studies and seminars will also contribute to this acceptance.
The company A.W Stahli AG regularly offers its own, practical seminars. They are aimed both at beginners and operating staff at user companies. As a supplement to this document, a further document about “Lapping technology” and training and operational films in four languages are also available from the author.
