Quick Change for Screw Machines

New quick-change dovetail form toolholders bring lean operations at a lean price.


The Knob Problem

The retention knob is an unmistakably critical component of the machining process. However, the tightening of the knob itself can lead to the toolholder not seating securely in the machine. You may be losing tool life to knob tightness without even ...


Detecting and Correcting Unbalance in Toolholders for High Speed Machining

This white paper from American Hofmann Corporation examines the relationship between unbalance and toolholders used in high speed machining centers. The paper looks at sources of unbalance, effects of unbalance, correcting the unbalance and determin...


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.


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.


Why Use Hydraulic Toolholders

The book on hydraulic toolholders is that they are fussy to set, fragile to operate and expensive to buy. So why do many shops choose them over other holders that seem less demanding? This Chicago mold builder has good reasons for its choice.


The Fluid Transition

A watershed moment in spindle evolution? For the latest generation of high speed spindles used in milling, spindle makers look beyond traditional bearings.


What's Possible At 10,000 RPM

High-value work doesn’t have to demand a high-cost machine tool.


Widening Range Of Grooving Tools

Traditionally, a grooving tool grooves, a facing tool faces and, of course, special tools do special cuts. Improved insert manufacturing technology and toolholder design is changing this tradition, allowing specialized tooling to be used more generi...


Cool Shrink Fit System

One of the neat things about metalworking is the wide variety of solutions generated for specific challenges. Shrink fit tooling is one such challenge. Much has been written and demonstrated about the advantages in concentricity, balance and ultimat...
