The KMG was intentionally designed so that the motor was not an integral part of the machine which allows for unlimited choices in how the grinder is powered. This allows you the use just about any type of motor and it also allows to set the grinder up with different speeds by changing the pulley ratio between the motor and grinder. We prefer drive the KMG with pulleys and a a belt to maximize the versatility, however you can also direct drive with a motor coupling of your choice. Typical motor sizes for the KMG can be from 1-1/2 to 5 hp.
We always recommend a grinder package such as the KMG-8 or KMG-10 that includes both, a contact wheel, and the platen attachment. These 2 attachments will be used constantly in your shop. The 8" and 10" wheel are equally popular and purchased on personal preference. A work rest is included.
With the standard 4" drive wheel, the abrasive belt speed is easily calculated as follows:
Belt speed (ft/min) = RPM (example: 100rpm= 100ft/min, 3500 rpm= 3500ft/min)
