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.
1 Team. 30 Hands. 300 Years of Workholding Engineering Experience.
January 24, 2012Hardinge 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.

Further Jones & Shipman purchases at FSG
November 3, 2011The first phase of a planned programme of capital equipment investment has seen the South Wales toolmaking design and manufacturer FSG Tool & Die invest in a further two new Jones & Shipman grinding machines.
With a heritage in precision grinding – the company started in 1961 as a specialist in the process – FSB has expanded its operations over the years to become firmly established as one of the UK’s leading die and mould manufacturers servicing a wide range of end users including metal, foil and plastic packaging, pharmaceutical, automotive and prototyping.
In its machine shops it operates a full spectrum of machine tools including 17 Jones & Shipman grinding machines of various models. Its top of the range cylindrical grinder is a J&S Ultramat CNC 4-axis external cylindrical grinding machine with a table mounted CNC diaform. As this machine is effectively dedicated to the requirements of one major automotive customer it has now been supplemented with a new J&S Ultramat 1000 Easy cylindrical grinder along with a new Techmaster Easy 634 profile and surface grinder.
“We undertook a detailed audit of available machines in these two categories and opted for the Jones & Shipman units on the basis of our favourable experience of existing machines and the proven levels of technical support and service backup we have come to expect from them,” explains Ian Slaughter, Business Improvement and Apprentice Training Manager at the Llantrisant plant. “Increasingly we are being asked for finished products in shorter and shorter lead times and we felt that investment in newer, faster and more adept machines was necessary.
The Ultramat 1000 cylindrical grinder offers us the best of both world’s having the dual automatic and manual capability – the manual option being very useful for what we call ‘nitty gritty’ work. This is very important in our environment and we estimate that when we have all of our programmes loaded the Ultramat 1000 will be able to accommodate some 90% of cylindrical grinding programmes we hold for our 300 plus customers.”
The dual capability aside, features of the Ultramat include ease of operation and set up – the latter using Jones & Shipman’s purpose developed Easy software that is touch screen controlled. Auto cycles include plunge, traverse, face, taper and thread grinding but if the operator requires running in manual mode, this is controlled by two electronic hand wheels. There are profile, dress and grind cycles and a re-grinding cycle is included for simple dimensional correction. For the most exacting tolerance work the minimum dimensional increment is 0.0001mm and the machining envelope can accommodate work pieces up to 300mm wide x 1000mm in length.
“The ease of set up and programming was an important feature for us. We have a long standing commitment to apprentice training at FSG (currently 12 apprentices) and they have found the ‘Easy’ control programme and its interactive features a very useful part of their training,” explains Ian Slaughter. “When in full production the Ultramat Easy will run 16½ hours a day and we are already appreciating the increased capacity and capability of the machine,” he adds.
The second new Jones & Shipman addition is a Techmaster Easy 634 heavy duty surface grinder, again equipped with an Easy touchscreen control. A feature of this machine is its ability to interpolate two axes simultaneously to enable precision grinding of complex shapes, profiles and surfaces. The operator is offered three modes of operation – manual, dress or grind – via a simple button control with automated compensated dressing on demand either in or out of the cycle. “Again, this purchase was born out of our need for additional capacity but also our ability to react quickly to customer.”
TF25-OG Overgrip Pick-off Collets for Citizen M20 and L720 Swiss Turning Centers
September 19, 2011Overgrip 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.

Who turned on the light switch?

Stop for a moment and take a deep breath… there, feels good right? It’s amazing to think where the industry was just a year ago and where it is now. A year ago we where preparing for IMTS 2010 and things appeared to be headed in the right direction. Today, it’s run as fast as you can because it is BUSY!
Now that we’re all running as fast as we can, the quest to do more with less is more important now than ever. That’s why in this article I’d like to review a piece of equipment we offer that’s a little hidden Gem. It’s called the GX480 APC. This is a 19″ X 16″ vertical machining center which includes an integrated pallet changer.
The American Machine Tool Distributors Association (AMTDA) states that the spindle utilization for a standard VM is around 30%. Obviously this is a very low percentage. This lack of production isn’t going to help when it comes to getting you ahead of getting your parts out the door. By adding the pallet changer spindle utilization increases as high as 70 percent! That’s a huge increase that will instantly make you more profitable with a very quick ROI.
The GX480 APC also brings a lot of capability with it as it can be equipped with various efficiency options such as High Pressure Coolant, Probing, Indexing tables, etc… All of these are options that can help increase your profits on top of what the machine already gives you in the APC
The base machine includes a 20 HP, 10,000 RPM Cat 40 spindle and has rapid traverse rates at 1,417 ipm. Add in the quick 2.2 Second tool change and 6 second pallet change with the machines compact size and you can see that this is a very fast machine.
As you can see, the machine really does bring the whole package and can truly help you do more with less.
