Used FELLOWS Fellows 10-4 Recontroled & Recertified CNC | Gear Shapers

Fellows 10-4 Shaping Machine Re-Control & Recertification Program - 3 Axes of CNC Control. Specifications below are typical for type, but may differ slightly as a result of the condition & type of your model.

The following program is for a Re-Control of your existing Fanuc controlled machine, with the work to be done in Machesney Park, IL. MTB will address the mechanical issues with the machine via our recertification program as detailed below. Some mechanical issues may be encountered during this program that may preclude the completion of the recontrol work - and these issues will be addressed on a case by case basis when they are over & above what we have listed here as the scope of work.

As your machine is understood to be already CNC controlled, the program we are offering herein is a hybrid, between our full rebuild program whereby we start from an electromechanical machine originally produced by the Fellows Shaper Company and a standard recontrol. So this recertification program serves to address the mechanical shortcomings of your machine which will involve some decisions after the core machine is received and inspected by our team.
