What Makes Ekstrom Carlson Better?
Live Tool Repairs
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 Ekstrom Carlson perform your repair?
Lead-time: 1–2 Week average turnaround for multi-spindle heads, including teardown, inspection, quotation, and repair. Right angle heads and live tooling repair are typically completed within 3–5 business days.
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.
