Feel Good Friday is back! Yesterday, Forkardt Hardinge attended the first annual career fair at Broadway Academy here is Elmira, NY. It was great to see these young minds learning about all local industries and businesses. There were a lot of questions and even more "oh... that's how it's made" moments. American made is still in full effect and making a difference!

How Collet Systems Are Actuated
Different applications require different methods for opening and closing a collet. Over the years, several closing systems have been developed to meet specific machining needs:

Mechanical Closers
Common on manual machines, these systems require operator input to actuate the collet. While rarely used on automated equipment today, cam-operated machines still utilize a mechanical closing mechanism driven by a cam.

Air-Operated Mechanical Closers
An early step toward automation, these systems combined traditional mechanical closers with an air cylinder for actuation. They were widely used on early Hardinge automatic machines before being replaced by fully pneumatic systems.

Pneumatic Closers
Ideal for precision machining and gripping thin-walled parts or tubing, pneumatic systems provide controlled, consistent chucking pressure. However, extremely heavy stock removal operations may require greater gripping force.

Hydraulic Closers
Hydraulic and pneumatic systems look similar, but their performance differs significantly. Pneumatic systems typically operate at 90–100 PSI using compressed air, while hydraulic systems can reach pressures up to 1,000 PSI. Because hydraulic oil is incompressible, hydraulic closers deliver substantially greater gripping force and resistance to collet opening under load.

TECH Tuesday – Did you know that there are three different types of collet systems.

Draw-In Collet
The Draw-In collet is the most common and also the most accurate for holding concentricity. To close the collet, it is drawn into the spindle angle. The only moving part (other than the collet) is the draw tube. Concentricity depends on the accuracy of the spindle and the collet. The order hole of the collet must run concentric with its head angle and back bearing which also must be concentric with each other. There are no other factors involved.

Push-Out Collet
The Push-Out collet is becoming obsolete. In the past, it was used in many manual turret lathes. To close the collet, it is pushed against a cap which is threaded or bolted to the spindle. The cap has an internal angle which mates with the front angle of the collet. The collet is closed by a forward force from the push tube. There are several items that affect concentricity: the collet, the spindle and the cap, along with its locating shoulder. All of these items require a tolerance when being manufactured. It is the build up of these tolerances which affects the total concentricity and accuracy of this system. Other items that affect concentricity are worn caps and caps that are not square with the face of the spindle.

Push Sleeve—Stationary Collet
The Push Sleeve system is the only system that allows length control of the workpiece. This is possible because the face of the collet is located against the back face of the hardened spindle cap. The collet is closed with a sleeve which pushes against the angle on the collet causing the collet to close, but not move longitudinally. Note: There are collets designed for part length control that are available for other collet systems. There are even more parts in this system to affect concentricity: the collet; the cap and how it aligns with its locating shoulder and thread; the sleeve with its allowance; as well as the clearance between the spindle back bearing and the collet’s back bearing. This system is the least accurate when trying to hold concentricity because of the large number of parts involved.

Today the Forkardt Hardinge team came together for our first All Hands with new CEO Ramy Shatoot.

A few hours to take stock of where we are, talk openly about what’s working and what isn’t, and walk through priorities for the first 90 days. What stood out was the team’s pride in this business and our customers, and a shared appetite to get better.

Forkardt Hardinge has built workholding solutions customers have trusted for over a century. Our job now is to honor that by serving them better every day. Closer customer connection. Sharper ex*****on. Continuous improvement, applied with discipline.

Thanks to the team for the warm welcome to Ramy and for an open and transparent discussion.

More to come from the Gemba.

Built for Speed. Designed for Flexibility.
When changeovers increase, your workholding must keep up.
The Forkardt Hardinge FlexC Quick Change Collet System delivers three critical advantages:
1. Speed
Change collets in less than 10 seconds using a compression wrench.
More uptime. Less interruption.

2. Flexible Gripping Range
One collet handles ±.020" stock variation.
That means:
Fewer collets to purchase
Reduced inventory
Faster setup adjustments

3. Parallel Grip Design
Reduces pushback and slippage — helping improve part consistency and surface finish.
FlexC accommodates:
✔ Round
✔ Hex
✔ Square
✔ Smooth or serrated bar material
It’s ideal for shops running small lot sizes or frequent changeovers.
