The Jupiter ATI series 6 is a fully automatic grinder which combines the accuracy of full relief grinding, full spin grinding and relief and spin grinding with the ability to grind bottom blades, in one machine.
It is fully programmable, with automatic traverse, indexing and infeed, returning cylinders and bottom blades back to manufacturers specification. It will grind up to 42" cylinders and bottom blades out of situ and converts to a bottom blade grinder in under a minute.

The Amazon is a dedicated bottom blade grinder which grinds top and front of the blade at the same time, saving time without compromising performance. Once set up it can be left running, allowing the operator to complete other tasks.
