CoolSpeed Mini | Cutting Tool Engineering [Video]

Many manufacturing companies and machine shops are striving to increase productivity of one area in particular: Micromachining. 

WTO is offering a new and affordable solution for micromachining applications. 

CoolSpeed® mini is a revolutionary patented ultra-high-speed spindle that can reach rotation speeds of up to 75,000 RPM. The spindle turbine is driven by coolant, cutting oil, or air mist. It is affordable, fits in standard tool holders for cylindrical tools, and is compatible with Milling Centers, Turning Centers, and Swiss Type lathes.

The patented spindle technology ensures continuous high precision. By its design, the cutting tool shank serves as the spindle shaft. As the result, the dynamic run-out is 4 microns or better. Bearings can easily be replaced by the customer with each cutting tool change. The CoolSpeed® spindle does not require any service.

The challenge in micromachining is how to achieve the required high rotation speeds. The majority of driven …
