Push your grinder closer to perfection with our professional grinder alignment services. Our Grind Chamber Sanding service will modify your Ek43 or EK43s grinder by sanding down the grind chamber and burr carrier, and checking that the burrs are mounted within 0.01/0.02 mm of perfectly parallel. Carefully sanding the grinding chamber is a simple way to ensure proper alignment - but please note that this process is not reversible.

NOTE: Only the new style Ek43's with the Aluminum burr carrier can be sanded/faced. The older steel carriers cannot. Pictured below is the black colour burr carrier which is Aluminium. Most of the newer EK43s (Short) models are coming with an aligned mounting face but out of align burr carrier. If that is the case for your grinder we won't have to face the grinder side mounting... Therefore will be cheaper cost to you we will just charge for verifying is aligned with our dial indicator.
