Machining a Stator

September 27, 2016  

FERMAT manufactures the most powerful and precise horizontal boring mills on the market.  They can handle any milling and machining tasks on workpieces small, large, or absolutely humongous.  They can mill, drill, bore, chamfer, and execute a myriad of complex machining techniques with a multitude of accessories from a robot tool changer, stepless universal automatic milling head, D’Andrea faceplate, to unusual and unique milling tools.

An example of the superb options available to any manufacturer or subcontractor to the heavy goods industry is the use of FERMAT’s best-selling table-type horizontal boring mill WFT 13 CNC to machine price-fetching products or components, such as molds, fracking pumps, valves, steering knuckles, hubs, foundations, bearing housings, and parts for heavy machinery, or even electric generator stators.

If machining valves, fracking pumps, and steering knuckles aren’t your cup of tea, how about the lucrative trade in supplying parts for electricity generation, how about those stators?  The indispensable, understated stator is the humble, unbudging stationary part of the rotary system in electric generators, among other devices, keeping the field aligned.  The stator remains static in relation to the rotating rotor at all times during operation; it is the stationary part in or about which a rotor revolves.

The video below demonstrates FERMAT’s WFT 13 CNC machining a stator, with smooth music and a description of the machining operation.

FERMAT’s WFT 13 CNC is a hard-slugging, powerful, deadly precise table-type horizontal boring mill made for medium-to-large or bulky workpieces weighing up to 20 metric tons.  With a spindle diameter of 130 mm, table travel along the X axis of 2 to 5 meters, headstock vertical travel of 2 to 3.5 meters, column travel along the Z axis of 1.5 meters to 2 meters, and spindle extension of 730 mm, there’s not much it can’t knockout in the middleweight division.  If punching even deeper into the center of the workpiece is what you need in your offensive moves, you can opt for FERMAT’s WFT 13 R CNC with ram stroke of 700 mm.

With its powerful headstock and high axial forces, WFT 13 CNC guarantees a solid, hard-hitting performance.  Its 80 mm Y-axis ball screw and sturdy column allows it to stand toe-to-toe without budging, making its milling and machining absolutely on target.  Other features such as its Heidenhain linear scales, thermal monitoring and stabilization system, and an extremely exact, no stick-slip CNC rotary table all combine to make FERMAT’s WFT 13 CNC superbly precise.

Another video shows one of the founding fathers of FERMAT, Mr. I. F. J. Ferenc himself, directly involved in mounting a stator.  He would’ve never guessed that years later his fledgling machine tool manufacturing company would grow into a world-renowned provider of high-quality horizontal boring mills needed to make such fantastic, albeit more modern, generators.
