This is what your early 70s Harig Autostep 618 could look like after it's been reconditioned & updated. Grinder rebuilds are always available for approximately 1/3 the price of a new machine. Harig machines are American made and parts are always available. Reconditioned machines can be rescraped & rebuilt to new machine tolerances! Email me for more information.

Together we can help clean all lubrication systems, set up proper lubrication techniques and preventative maintenance schedules, and check all tolerances to ensure your machine functions properly for many years to come.

Did You Purchase a Used Grinder?

Once we know the machine you’ve purchased by asking a few simple questions, we can give you the year your machine was made, assist in it’s set-up, instruct you on it’s operations, email any manuals, and help to create a preventative maintenance schedule. JDS Tech Support can also email detailed pictures of the areas of the machine you are having technical difficulties with, pointing out where to look for problems. This will make it both easier to resolve the machines issues, and be more cost effective for you, our valued customer.
