Krebs & Riedel
Krebs & Riedel who were founded in 1895 have been manufacturing high quality conventional, diamond and CBN abrasives for well over 100 years and we are able to count leading UK engineering companies such as Perkins Engines, Grundfos and Delphi Diesel Systems amongst our ever growing customer base. Krebs who employs approx 220 people is constantly introducing new types of wheels with improved grain structures and novel bonding systems that enhance grinding wheel quality and optimise performance.
One area where Krebs & Riedel excels in is the supply of very special wheels for gear and thread grinding applications and special wheels are available to suit machines manufactured by Gleason-Pfauter, Oerlikon, Kapp- Niles, Hofler, Maag, Samputensili and Reishauer etc. Krebs are also a member of the “Gear Research Circle” at Aachen University and are heavily involved in developing advanced wheels for the latest production technologies employed by leaders in the field of gear manufacture. So successful have the Krebs & Riedel gear grinding wheels been they have become the major supplier to leading machine companies such as Kapp. For specially profiled wheels for gear production Krebs keeps customers blank wheels in stock and upon order will profile these to suit and then supply within just 2 days. We supply several major UK gear manufacturers with Krebs wheels.
Another area where we have more and more references is within the aerospace industry for Krebs wheels that are grinding parts such as aero-engine turbine blades and segments. Here Krebs have developed specially bonded wheels that have an open structure to ensure coolant has as much access as possible to the grinding point to avoid the risk of burning parts and damaging the surface structure of parts that can otherwise result in very expensive scrap.
Diamond and CBN wheels that have been manufactured by Krebs & Riedel for more than 20 years are available from 3mm to over 900mm in diameter with peripheral grinding speeds of up to 160 m/s.
We have over £100,000 worth of wheels in-stock at our works in Coventry that are held under Kan-Ban arrangements for our UK customers who can draw from that stock for instant supply. We also supply free of charge stock wheels for immediate drawdown by our customers that hold stock wheels at their works and pay upon their use; not upon supply.
Another of Krebs & Riedel’s specialities is wheels for the grinding of Camshafts and Crankshafts. Krebs have developed very special tri-zone large diameter CBN wheels that generate perfect geometry combined with very fine finishes on Crankshaft journals. These special wheels that are the result of long-term wheel development projects with major machine tool manufacturers such as Junker employ 3 different CBN grades on the same wheel without glue and avoid the problems of burning on the surfaces of Crankshafts that can sometimes occur when grinding at very high speeds.
