The Coolspeed spindle from WTO turns legacy machines into high speed machining centres.Click image to enlargeWTO’s CoolSpeed mini is an ultra high speed spindle that reaches up to 75,000 RPM for micromachining applications.

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 centres, turning centres and Swiss Type lathes.

By its design, the cutting tool shank serves as the spindle shaft. As a result, the dynamic run-out is 4 microns or better. Bearings can easily be replaced by the customer with each cutting tool change and 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 tools or spindles are mechanically-driven, which have difficulty reaching the speeds required in micromachining.

It can be driven by through coolant, oil or air mist, with coolant pressure ranges from 145-870 psi with a max. rotation speed of 75,000 rpm. When operating with air mist, the pressure range is from 58-73 psi with a max. rotation speed of 55,000 rpm. There are models that support a supply line for point-to-point coolant, oil, or air mist supply line connected directly to the high-speed spindle unit.  Compressed air is commonly available in machine shops and can be easily utilized to convert an older piece of equipment into a high-speed machining center.

The ins and outs of thread milling

There are many elements to consider when threading a workpiece. When is a solid carbide thread mill better than an indexable? How does the workpiece material behavior impact thread milling? Understanding your program as well as diagnosing issues that arise are just as important. Luckily, thread milling can be better understood by asking five specific questions.
