Themac grinders are unique in both their feature set as well as their construction. These features have made Themac the most trusted brand of tool post grinders.
ECCENTRIC SPINDLE TUBE (an exclusive Themac feature)
The eccentric spindle tube provides for positive manual belt adjustment, ensuring proper belt tension at all times. The motor and spindle assembly remain parallel under all conditions. The belt tension will not cause misalignment of grinding spindle because the motor and spindle assembly are securely locked in position. There are no springs or hinges to permit side movement when the grinder is in operation; thus the possibility of setting up vibration is reduced to a minimum.
Pulley alignment can be set so that belts will always remain on pulleys and transmit full power.
SECURE TOOL POST CLAMP BRACKET
Themac grinders attach directly to the top compound rest. An easy-to-get-at locking device securely locks the clamping nut in T-slot - providing one of the most secure mounts on the market. No overhanging weight to cause vibration.
MOUNT ON ANY MACHINE TOOL
Although used principally on lathes, exclusive features make Themac grinders a natural for mounting on shapers, planers, millers, boring mills, surface grinders or special units. Units can be operated in vertical or horizontal positions.
All Themac grinders are equipped with grease sealed-for-life ball bearings - no lubrication required.
The circumferentially adjustable grinding spindle can be locked and operated in any position within the range of adjustment. The locking arrangement is simple and positive.
QUICKLY ADJUSTABLE TO ANY LATHE CENTER
It is possible to mount Themac grinders on the smallest bench lathes with the grinding spindle center to lathe center. Through the adjustment of the compound rest or by swinging the grinder, any angle can be obtained. Grinding wheel can be used on right or left side... front or rear of the motor. The circumferential and horizontal swing features allow the operator to place the grinding wheel in front of the motor for external and internal grinding, or the grinding wheel can be swung to the rear of the motor for large diameter external grinding. By swinging the grinder around, the wheel can be operated on either side.

- Diamond Dresser
