Hyper Spindles Allow Increased Tooling Revolutions and Reduced Cycle Times

Originally titled 'Spindles Allow Increased Tooling Revolutions and Reduced Cycle Times'

These holders are designed to allow increased tooling revolutions and reduced cycle times with a company’s current equipment, without the need to invest in new machines.

NT Tool’s Hyper Spindles use a 1:5 ratio internal gear system to multiply the rpm of existing machines up to five times at the cutting edge, with a maximum of 30,000 min-1, according to the company. These holders are designed to allow increased tooling revolutions and reduced cycle times with a company’s current equipment, without the need to invest in new machines. Since the Hyper Spindle does not use a pneumatic system requiring an air hose, it is fully compatible with ATC arms.

The Hyper Spindles are made with precisely ground steel gears to ensure minimal noise and vibration. A built-in cooling fan prevents overheating, allowing long, interrupted machining cycles without fear of breakdowns. Every Hyper Spindle holder is manufactured with an electromagnetic, rustproof coating that prevents the spindle from wearing abnormally and allows the holder to maintain its accuracy throughout its tool life. According to the company, it is the only toolholder manufacturer to provide rustproof coating, and it comes standard with most items in its catalog.

Like many of NT Tool’s collet holders, the Hyper Spindles use the company’s 12-degree taper FDC collets. By using a more gradual taper than 16-degree ER collets, FDC collets grip the cutting tool more evenly, increasing gripping force and reducing slippage, the company says. The even grip also keeps runout below 5 microns, whereas ER collets can only guarantee 10 microns.

Hyper Spindles are available in CAT and BT shanks, with other shanks readily accommodated as custom orders. Collet sizes accommodate tool shanks as small as 0.5 mm (0.020”), all the way up to 12 mm (0.472”).
