Magnetic clamping balls simplify work holding

Manufacturing companies, engineers and machinists can now freely position and hold workpieces on large surfaces thanks to Norelem’s newly developed magnetic clamping balls.

Quick and flexible holding of parts is particularly essential in tool and die making. Tool makers must be able to laser weld, polish, assemble and adjust parts so they fit together properly, with maximum flexibility and efficiency. Using Norelem’s magnetic clamping balls, rapid clamping and releasing is now possible.
Released in four different sizes with magnetic faces of 80 to 160 mm diameter, the workpieces are clamped through a permanent magnet. The magnet has a nominal magnetic force of up to 100 N/cm², which can be switched on and off using a hexagonal key. When the key is rotated 120°, the magnet’s force is fully realised, while partial clamping force is also possible so that parts can be positioned easily.
CEO of Norelem Marcus Schneck says: “Efficiency and increased productivity are the name of the game in engineering, and with our magnetic clamping balls, engineers can accelerate their processes when machining and tooling up for jobs. Using a simple turn of a key, workpieces can be adjusted quickly, providing an unobstructed surface for the engineering task in hand.”
Norelem’s magnetic clamping balls can swivel up to 90°, depending on workpiece geometry and weight. To ensure a high-quality finish, the magnetic face has fine, 1.5 mm poling and is mounted in an anodised aluminium globe. The globe is held in position by a stick/glide effect and lays in a leather lined, nickel-plated steel ring.

Gleason to buy gear-honing business

Gleason Corp has signed a definitive agreement with Daetwyler Industries AG and MDC Max Daetwyler AG to acquire all assets of Daetwyler’s Faessler gear-honing business.

Under the Faessler brand, Daetwyler has been producing gear-honing machines, related work holding and tools for the high-precision, hard finishing of gears. The business operations of the Faessler division, which has approximately 70 employees, will be acquired by a new Gleason subsidiary, Gleason Switzerland AG, and will continue to operate at its current locations in Bleienbach and Dietikon, both in Switzerland.

SiG success

Family-owned precision engineering firm JJ Churchill of Leicestershire has secured more than £100m in contracts, increased its headcount by 35% and its export forward order book from under £1m to more than £37m after five years on the Sharing in Growth productivity and competitiveness programme.

The Market Bosworth-based company was one of the first aerospace suppliers selected for Sharing in Growth in 2013 when its ambitions were to overcome risks caused by the oil crisis. JJ Churchill now has plans to hit more than £38m and add around 20 new jobs by 2020.

Okuma five-axis machine released by NCMT

Okuma is now offering an entry-level five-axis machining centre that is capable of handling workpieces up to 600 mm in diameter and 400 mm in height, with a maximum weight of 300 kg. The Genos M460V-5AX, which is available in the UK from NCMT, features a 48-station tool magazine.

Featuring a spindle that offers 15,000 rpm, the machine can achieve high productivity for a range of applications. Providing a maximum power output of 22 kW and up to 199 Nm of torque, the spindle is said to process demanding materials with ease. The spindle’s five sets of bearings are lubricated with oil mist and do not therefore require maintenance. By providing through-spindle coolant, the spindle adds to the shower coolant function. Manufacturers benefit from a three-year spindle warranty that is not limited by number of shifts or operating hours.
For efficient and accurate measuring, the machining centre is equipped with a Renishaw RMP60 touch probe, while the X, Y and Z axes possess an absolute scale. In addition to the hardware, intelligent technology apps like ‘Machining Navi’ for reducing chatter or ‘5-Axis Auto Tuning System’ for compensating geometrical errors, further enhance the machine’s accuracy. As a result of these measures, Genos M460V-5AX achieves a positioning accuracy of 2 micron in X, Y and Z.
For highest precision, the 5-axis machining centre is equipped with Okuma’s Thermo-Friendly Concept. This technology includes a symmetric, box-build, double-column construction made of cast iron. To eliminate any negative influence from the coolant and hot chips, the machine possesses a thermo-shield design. In addition, five sensors in the machine and three sensors in the spindle measure temperature changes and allow for active compensation of thermal deformation.

Five-axis Quaser at Wilson Manufacturing

Machining specialist Wilson Manufacturing has purchased a Quaser MF400UH five-axis machining centre from the Engineering Technology Group (ETG) to complete a £310,000 investment drive. The acquisition, which complements the earlier addition of a mill-turn centre, will help the company improve lead times and drive efficiencies.

Based in Hampshire, Wilson Manufacturing, which supplies precision parts into the aerospace, marine, medial and oil and gas sectors, will use its Quaser MF400UH to increase capacity, boost quality and reduce set-up times. The move marks a successful year for the Ringwood-based company, which has seen it create two new jobs and increase sales by 25%, putting the business on course for a turnover of £1.35m.
“Customers are spread across a number of demanding sectors and there is an increasing need for more complex components, a trend that we’ve met head-on with the purchase of the five-axis CNC machine,” explains director Andy Wilson. “We discussed our requirements with ETG and they spent a lot of time getting to understand our processes and the parts we make. This was crucial in providing a complete picture of where we wanted to go, and led to them suggesting the Quaser MF400UH.
“Although it has only been up and running for a few months, we have already been really impressed with the performance,” he continues. “The control, spindle speed and ability to machine multiple faces of complex parts have been game changers – in some instances we have improved cycle time by 30%. This makes us a lot more competitive and, at a time when speed-to-market is crucial, gives us another USP when exploring new business opportunities. We could well make a return on our investment within the first two years.”
