Collet stops are used for chucking applications to eliminate push-back of the collet during heavy drilling or other endworking applications. This assures accurate repeatability from part to part. Hardinge collet stops are adjustable and machinable for the desired part length. Ejector stops will automatically spring-eject the part when the collet opens.

Hardinge Inc. (Elmira, New York) has a talented group of workholding engineers with over 300 years of combined engineering experience. These hands (and intelligent minds) are ready to improve accuracies, reduce setup times, reduce costs, add flexibility to a machine, develop new workholding concepts and solve gripping problems.

There isn’t a shop worldwide that can say they’ve never had a problem gripping a part. “It’s an odd shape, it’s slipping, it’s too delicate, it’s getting scratched, there is not enough gripping surface, or it’s threaded.” The list goes on and on. Before sinking hours into experimenting and creating a pile of scrap metal, the logical, fail-safe move would be to put these frustrating gripping problems in the hands of experience, where the end result will be safe, accurate and reliable.

According to Hardinge, no job is too small or too big, whether you’re just starting up a job shop or you’re the senior engineer from Boeing Commercial Aircraft division — it’s people helping people. According to Matt Roberts, Engineering Manager at Hardinge Workholding, the 300 years of combined expertise revolves around manufacturing, mechanical, applications, programming, electrical and design engineering. Hardinge and their engineers hold several active patents for new and improved workholding products. As a company, Hardinge supports the Society of Manufacturing Engineer’s local chapter 24, with several of their engineers as members. SME Chapter 24 is active in promoting a skilled workforce in the Twin Tiers of New York and Pennsylvania. This chapter is a networking resource for the local members and other local manufacturing engineers and professionals. Joe LaRussa, SME Membership Director, states that SME members are exemplary individuals who are on the leading edge of manufacturing knowledge. “Our members of Elmira 24 are great examples of the 21st-century workforce, contributing daily to the success of their companies. Hardinge and SME both benefit from the synergies between our organizations,” says Joe.

Overgrip collets, also referred to as over-the-shoulder collets, are used on a pick-off spindle when it is required to clear a shoulder and grip on a smaller diameter beyond. A good example of this type of part would be a screw. Hardinge has developed and now manufactures standard TF-25 OG overgrip collets for Citizen M20 and L720 lathes. Extra spread is required to open the collet wide enough to go over the screw head or larger diameter. Hardinge’s collet design incorporates teardrop slots and reduced wall thickness for maximum flexibility for the overgrip pick-off process.

ShopHardinge.co.uk – 65,000 reasons to buy!

 ShopHardinge, the highly successful USA developed concept for online selection and purchasing of Hardinge workholding, rotary products, tool holders and machine tool accessories is now launched in the UK.

With 65,000 products in its online inventory, the ShopHardinge.co.uk e-commerce web site offers purchasers the opportunity to browse, select and purchase a vast range of products ranging from a simple collet to a sophisticated rotary table. 

“ShopHardinge has been up and running in the USA for the past 2 years so they have first hand operational knowledge of how it works in a live environment,” explains Rob Beckett, Hardinge UK’s Workholding Product Manager.“In adapting the idea for the UK we have had to make changes to the pricing structure and various aspects of the site behind the scenes, but in essence the model is identical and we are now live in the UK.”

 From the customer viewpoint ShopHardinge could not be easier.

 The simplicity of the concept is based on three easy steps – “Log in … Shop … Check out …”

 Customers can charge their purchases to their account in the normal way for monthly billing but there is also the opportunity to purchase via a debit or credit card.

 “There are other areas of the site that will prove particularly helpful to our distributors.” adds Rob Beckett. 

 “After we have allocated them a unique password, as with direct customers they can check stock on line and then purchase what they need without having to phone through.  This will greatly streamline the whole purchasing process and ensure we are in a position to provide exceptional levels of support to ensure customers get the products they want when they want them.

“Regularly purchased items or repeat orders are facilitated by a ‘Quick Shop’ feature that enables a re-order at the click of the mouse and there is an order history section,” he adds.
