ETG gets a grip on clamping

ETG Workholding has been appointed the exclusive UK supplier for the German Spreitzer range of precision tools, nike air max specialising in the development and manufacture of standard and bespoke solutions in the field of clamping and measuring. Nike Air Max 2016 Dames wit A product range that ETG Workholding will be particularly promoting is the MZR range of mechanical centre vices, which offer the ability to securely clamp raw material workpieces without the need for pre-stamping. Asics Gel Lyte 3 “There are many options for raw material clamping but the vice is only part of the solution,” states ETG Workholding’s product manager Rob Beckett. Oregon Ducks “Raw materials mostly need pre-stamping, St. Johns Jerseys which adds further cost over and above the purchase cost of the vice, air max 1 pas cher and adds time to what is essentially a very straightforward operation. “MZR vices are ideal for working on multi-axis machining centres,” he adds “as they are compact in design with a small trunnion footprint yet still offer maximum access and the ability to enlarge the clamping width with reversible jaws.” Raw part machining uses the grip jaw option with the second set up for finish machining using the smooth jaw option – all without pre-stamping. Air Jordan 6 For Kids Depending on the jaw clamping width selected (four options between 70 and 195 mm), Jordan Hydro Retro a maximum clamping force of 40,000 N is achievable. This grip contributes further to reduced cycle times, enabling raw workpiece materials to be rapidly positioned, nike air huarache hombre clamped and positioned ready for machining. “Our agreement with Spreitzer is exciting as it brings a whole new range of high-quality, German manufactured equipment to the UK at very competitive prices,” concludes Beckett.

10-second changeovers with combi-collet chucks

When Parker Precision set itself on a course to improve productivity, precision and output, the Bilston-based business acquired a Mazak QuickTurn 200MSY turning centre equipped with a Hainbuch collet chuck. New Balance 574 mujer The impact of the new investment soon snowballed into a raft of new machine purchases. Canotte Los Angeles Clippers Installed in 2012, the Mazak was purchased for its sub-spindle turning capability with the aim of reducing second operations, part handling and the potential for error, as well as improving throughput. ADIDAS VALCLEAN2 CMF The impact of the QuickTurn rapidly noted the arrival of a second 200MSY, a 250MSY and a Hyper Quadrex – all fitted with collet chucks from workholding specialist Hainbuch. Arizona State Sun Devils Jerseys Commenting upon the delivery of HainbuchSpanntop Combi collet chucks with the Mazak machine tools, director at the 28-employee subcontract company, Marc Corns, says: “When we set about replacing machine tools with new technology, our concern was transferring complex parts from the main to the sub-spindle and maintaining our average ±0.01 mm tolerances on dimension and concentricity precision. Air Jordan 7 Uomo To this end, Mazak recommended a Hainbuch 65 mm diameter Spanntop Combi collet chuck for the sub-spindle. Andrew Luck – Stanford Cardinal This worked so well on the first machine, we specified the Hainbuch collet chucks on the sub-spindle of every subsequent machine installation. nike air max goedkoop “One thing we can quantify with the Hainbuch system is the savings in regards to collet changeovers,” he adds. adidas shoes uk “Our previous 5C collet system on the old machines used to take up to 30 to 45 minutes to change over.

Small hydraulic tool-holders from Big Kaiser

Big Kaiser says it has launched the world’s smallest hydraulic tool-holding chuck for HSK-E25 machine spindles. Offered in the UK market by Industrial Tooling Corporation Ltd (ITC), the new HDC line completes the range of Big Kaiser Super Slim hydraulic chucks.
Super Slim HDC chucks are designed for precision finishing processes in confined areas with drills, reamers, ball mills, end mills, diamond reamers and grinding tools. Only a single wrench is required for clamping and unclamping. Furthermore, the chucks can clamp tools down to 3 mm in diameter without needing a reduction sleeve.
When clamping 3 mm diameters, the external diameter of the chuck nose is just 14 mm. Moreover, at a length of 90 mm, the diameter is only 25 mm. This slender design means that interference contours should no longer pose a problem.
Super Slim HDC chucks are available for HSK-E 32/40/63 and BBT 30/40/50 spindle variants.

Hydraulic chuck suits EasyFix boring bars

Gewefa has developed a hydraulic chuck for holding SandvikCoromantEasyFix boring bars that removes the need for reduction sleeves while eliminating run-out and guaranteeing centre height at the insert cutting tip.
Setting time is reduced by as much as 75%, says the company, with the Gewefa design featuring a spring plunger mounted in the toolholder body. This locates into a fine groove machined into all SandvikEasyFix boring-bar shanks and aligns the bar position precisely for the correct centre height. Along with the hydraulic chuck operation, a secure grip is guaranteed with integral anti-vibration damping to optimise the machining process.
By eliminating the previously accepted method of securing boring bars into a toolholder with reduction sleeves, the opportunities for inaccuracy and bar deflection during boring operations are now reduced.
Gewefa also offers a solution for other proprietary systems with the ground angle on the back end (of the bar) locating against a stop pin at the base of the toolholder. This ensures precise central positioning and orientation with the bar then locked into the hydraulic chuck.
The advantages of all systems is said to be a 50% increase in cutter life due to the more secure, vibration-free grip, guaranteed repeatability when changing like-for-like bars and a simple, fool-proof fitting process.

Inoflex chuck aids Micron Precision

Brixworth-based Micron Precision Engineering has matched a recently installed DMG Mori DMU75 Monoblock machine tool with an InoFlex concentric and compensating four-jaw chuck from Thame Workholding.
“As standard chucks are somewhat limited, we searched for a secure, fast and flexible workholding method to help ensure the new machine’s efficient operation,” explains general manager Stuart Denton-Beaumont. “A visit to an exhibition provided the answer we were seeking. Thame Workholding recommended and demonstrated the capabilities of the Inoflex four-jaw self-centring chuck. As the Inoflexis able to securely hold a range of odd shapes and is extremely versatile, we were happy to place an order.”
Now fitted, the VD050 closed-centre 4-20” capacity Inoflex chuck has proven to be easy to use, fast to set-up and repeatable.
“Most of all, we have been impressed by its adaptability and ability to securely hold any shape of component,” says Denton-Beaumont. “Now, our new machine tool and Inoflex chuck have enabled us to take on a range of additional work.”
Gareth Barnett, Thame Workholding’s sales manager, adds: “In the past, companies have used rigid, concentric three-jaw chucks for clamping round parts and worked with two-jaw vices for rectangular and geometrically irregular components. Now, the trend is towards combined turning and milling machines for the production of round, rectangular and geometrically irregular parts. Thame Workholding has reacted to these developments by offering the first universal clamping
tool for holding circular, rectangular and asymmetrical shaped parts.”
