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.

Faster surface finishes with stream technology

A new generation of stream-finishing machines built by OTEC Präzisionsfinish is now available in the UK from Fintek. The SF1-Automation with chain loader is typical of the range. The ability to load and unload without stopping ensures the best return on capital investment.

In stream finishing, components are clamped in a holder and lowered into a rotating container filled with grinding or polishing media. The finishing effect is generated by the media flowing around the parts, as well as independent rotation of the components. The process offers very short finishing times.
Smoothing, polishing, edge rounding, deburring and removing coating droplets are all tasks at which the OTEC SF1 is said to excel. A combination of these is usually performed in a single operation, producing surface finish values as low as Ra 0.01 µm.
The SF1-Automation chain loader has 64 positions which can change in diameter according to the workpiece or tool to be processed. Parts ranging from 3 to 32 mm in diameter can be finished in a single batch.
Cycle times depend on the complexity of geometry and standard of finish required, but typically range from 30 to 300 seconds. The SF1 is suitable for both dry and wet finishing.
OTEC stream finishing units are available in different drum sizes and with different media/compounds. Fintek is able to supply all supporting services, including installation, training and support.

Software and robots from Anca

Visitors to the stand of Anca at EMO (Hanover, Germany) this week will find out how the company’s latest software product launch, Management Suite, aids customers keen on adopting Industry 4.0 strategies (Hall 6, Stand K59). Also in action on the stand will be company’s first Dual Robot technology.

Anca’s Management Suite provides customers with the technology to monitor the performance of their machines no matter where they are in the world. The software also enables companies to run smart factories by providing live production information that enables staff to make data-based decisions about operational improvements.
CNC grinders from Anca now have the capacity to integrate several manufacturing operations into a single production line using the company’s first multi-robot production cell solution. Using a single robot, TXcell can automatically load both the grinding wheel packs and the workpiece. However, with the addition of a second robot in the TXcell, the solution can also complete secondary operations unmanned.
A further innovation in the EMO spotlight will be the new TX Linear, which will be on show for the first time in Europe. Among the stand-out features are Anca’s LinX linear motors on the X, Y and Z axes, an updated Anca AM5X CNC and servo drive system, and a new user-friendly front panel with touch-screen and ergonomic tilt adjustment to suit different operator heights.

Delivering speed and accuracy to polishing firm

Prompted by increasing demand, Oldham-based North West Polishing Ltd is currently involved in further expanding its production facility and investing in new, highly efficient plant. As a major element in its latest expansion phase, the company recently purchased a VG T-300-3K polishing machine from Ellesco.

Managing director Andrew Marston says: “Having previously purchased polishing machines from other suppliers with somewhat mixed results, we turned to Ellesco. Together, we came to the conclusion that the T-300-3K polishing machine would satisfy our requirements. Following a trouble-free installation and operator training, our new polisher is now enabling us to process much greater quantities of products in a range of high-quality finishes. Furthermore, the speed of the machine ensures that we are able to deliver within the strict timeframes required by our customers.”

The VG T-300-3K uses three abrasive belt heads fitted with 300 mm belts, each driven by individual 7.5 kW motors. According to Ellesco, swapping from one abrasive belt grade to another is both quick and easy. The machine boasts pneumatic floating linishing heads that automatically compensate to ensure consistent pressure is applied to long, non-uniform workpieces. In addition, the T-300-3K provides powered adjustment for different thicknesses of bar and box-section products, while automatic belt tension removes unwanted oscillations.

With a through-feed conveyor, speed adjustment allows slow throughput for demanding applications such as heavy scale removal and pronounced extruder draw lines, through to fast throughput speeds for fine finishing and jobs where minimal heat generation is a requirement.
