Get A (Tight) Grip
High toolholder gripping torque reduces the likelihood that a tool will slip within a toolholder during a cutting operation. A mechanical toolholder design provides a very high gripping torque via a worm gear that compresses a shallow-taper collet t...

Boosting Machine Spindle Speed For Micromachining Applications
Small-diameter micromachining tools require very high rpm for sufficient cutting speed and material removal rates. This air spindle provides 80,000 rpm and an untethered compressed air interface to allow automatic changeovers using the machine's ATC...

Engineering The Toolholder Assembly Process
This assembly and mounting device for V-flange toolholders is designed to make it easier and safer to put toolholders, collets and cutting tools together. The device allows the toolholder to be clamped securely and rotated so that both ends of the a...

Toward More Seamless MQL
One of the small perils of a new technology is that it often involves new steps or new considerations that present special opportunities for error. Minimum quantity lubrication (MQL) is a technology that exemplifies this point.

The Real Cost Of Runout
A seemingly small amount of runout can still be too large for the tool. Reduce this runout, and tool life or productivity may dramatically increase.

Don’t Forget The Drawbar
The force that holds the toolholder in the machining center's spindle can weaken over time. If you haven't checked drawbar force in a while, this may be the weak link in your process.

Coolant-Through Turning Toolholders Deliver Increased Performance And Tool Life
It should be obvious to anyone who has ever washed a driveway or patio with a garden hose: For the best results, you must keep the stream of water precisely where it's needed. The same principle applies to delivering coolant to the cutting zone.

Up To 12 Tools In One Holder
Imagine a single cutting toolholder that can be used to perform 12 distinct metalcutting operations without a tool change. That's the concept behind a new cutting tool innovation designed and built by Mazak.
