We specialize in the repair of Benz right angle drills, Benz right angle milling heads, Benz variable angle head, Benz aggregates, and various Benz tooling units. Our repairs will typically cost 1/2, or less than 1/2 the price of a new live tool. Plus, we can upgrade the original non-sealed bearing design, to a sealed / shielded bearing design at all bearing locations. We keep bearings in stock for these live tools to allow us to keep pace with our repair volume. Lead-time can be as short as 2-3 days.[/threecol_two_last] [hr]

- The spindle journal diameters show no appreciable wear and are acceptable for proper bearing fits.
- The housing is worn where the bearing sits on the drive shaft. We recommend boring and bushing the housing.
- The taper runout is acceptable. Our proposal provides no repair to the spindle taper.
- The bearings show some wear on the inner and outer diameters.
- The gears are in good shape and show little wear.
- The unit will be assembled and tested.

- Most live tools exceeding 0.001″ runout are due, or almost due, for a repair. 0.0008″ or less is the target runout for a live tool.
- Live tools like to rest as long as they cycle at full speed or maximum load. 5 minutes is a typical maximum run time followed by a 5 minute rest.
- 150 to 160F temperatures are common when running at full load.
Why should you have your multi-spindle boring head, high speed right angle head, or other aggregate head, repaired by Ekstrom-Carlson?
- Lead-time: 1-2 Week average for multi-spindle heads, including tear down, inspection, quotation, and repair. 3-5 days for right angle heads and live tooling repairs.
- Price: Much lower price than the OEM, or the OEM distributor.
- USA repair: We repair the unit in Rockford, Illinois. It is not shipped overseas, as is often the case for various machines.
- Parts repair: Where possible, we will save money by repairing motor spindles and gear spindle shafts. Some manufacturer’s representatives will always quote a brand new unit if the unit drive shaft is damaged, or if the bearings require replacement. 75% of the time, we can save the original unit at less than 50% the cost of new.
- Sealed bearings when available and possible conversion to ceramic bearings.
- Free inspections.
