Trouble-free groove milling

The new CoroMill QD groove milling concept from Sandvik Coromant features internal coolant and dedicated insert geometries for milling with high process security.

The main challenge in groove milling is often chip evacuation. Chip issues often harm production efficiency, lower component quality or cause tool breakage, especially when machining narrow and deep grooves. Dedicated for groove milling and parting off operations, CoroMill QD takes care of chip issues with optimized geometries and the unique internal coolant solution. The chips are deformed by the insert geometry to a more narrow shape than the groove and then flushed out by the coolant. Combined with long and predictable tool life, this makes CoroMill QD a reliable solution for secure and trouble-free production processes.

Complementing the new cutters is a wide range of new adaptors. These adaptors enable use of CoroMill QD cutters regardless of whether the preferred machines are small- to medium-sized machining centres, large machining centres or multi-task machines. Silent Tools™ adaptors are available for long overhang machining.

The internal coolant is based on a four-channel delivery solution from the adaptors to the cutter. By implementing this solution on the new adaptors for CoroMill QD, coolant delivery into the groove is achieved.

A tremendous declaration of loyalty to AMB, which will take place over five days, from 13 to 17 September 2016, in Stuttgart. “The overwhelming demand stresses the character of AMB as the leading trade fair, which in even-numbered years takes pole position in Germany,” says Gunnar Mey, Manager of the Industry department. “With our new hall, which will be completed by 2018, we have set a clear signal for the further expansion of AMB.”

The focus in 2016 will be on novelties and innovations

Current themes, such as improved efficiency, Industry 4.0, increasing intelligence in the machine periphery and possibilities with regard to simulating the machining processes, will be the centre of interest. An attractive accompanying programme with awards for the “Lathe operator of the year”, the “Special show for young people” and the “European MINT Convention” will be additional crowd pullers. The integrated concept of AMB, which takes place in the heart of Germany’s top region for the machine tool and precision tool industry, last year broke new records: With 1,357 exhibitors in nine booked-up halls covering a total area of 109,000 square meters, and over 90,000 visitors, of whom 15% came from abroad,

AMB has clearly established itself as the leading trade fair in Europe and the number one in Germany in each even-numbered year. Registration has begun. “Everyone submitting their documents by 30 June 2015 can expect to take part in AMB 2016,” says Gunnar Mey. The allocation of floor space will start in September.

With AMB China, Messe Stuttgart is further emphasising its international character. AMB China will be taking place for the fifth time from 19 to 22 October 2015 in Nanjing. Last year, AMB China had over 250 exhibitors, of whom 76 came from
abroad, and over 11,000 visitors.

PTG heavy industries achieves new heights in friction stir welding exotic alloys

Ever since the launch of its Crawford Swift ‘Powerstir’ CNC Friction Stir Welding (FSW) machines in 2000, PTG Heavy Industries has been acknowledged as a global leader in this innovative means of jointing metals.

Crawford Swift Powerstir Friction Stir Welding, from PTG Heavy Industries.

Exotic steel and titanium for aerospace
Recent research and development activities at PTG Heavy Industries’ UK-based HQ, however, have taken the capabilities of the welding specialist’s FSW machines further than ever before – to include the successful jointing of exotic steel and titanium alloys that are particularly suited to the uncompromising requirements of space and aerospace applications.

Aerospace-grade titanium of 3mm – 8mm in thickness
“We have successfully welded both aerospace-grade steel alloy and aerospace-grade titanium in thicknesses of 3mm and 8mm, using our proprietary PTG fixed pin tooling techniques,” comments PTG Heavy Industries’ Sales Manager, Chris Cheetham.

“Although each presented distinct challenges, including the potential for workpiece distortion and ensuring sufficient heat transfer when blending thicker materials, these issues were overcome.”
Comprehensive research programme
As part of its research activities, PTG Heavy Industries also achieved excellent results when working with various exotic aluminium alloys ranging from 2mm to 35mm in a number of challenging configurations.

Impressive results with exotic alloys of 40mm in depth
Our successes have been such that we now look forward to applying our findings, approach and technologies to robust testing on other bespoke alloys that are used across the avionics sector,” adds Chris Cheetham. “For example, we have also achieved good results working with exotic alloys of as much as 40mm in depth.

Superior welding for planes and high-speed trains
Since their launch, Powerstir Friction Stir Welding (FSW) machines have attracted considerable interest from organisations seeking an innovative way of creating superior high-strength welded joints, without the detrimental and visible effects typically associated with conventional welding.

From small, intricate components to automotive products, aircraft manufacturing, railway carriage panels and shipbuilding, Powerstir Friction Stir Welding provides a clean, highly aesthetic alternative to traditional welding. A method that delivers proven weld quality, FSW offers excellent mechanical properties and virtually no porosity.
Patented by TWI (The Welding Institute), Friction Stir Welding is a unique and innovative means of jointing metals. The process combines frictional heat with precisely controlled forging pressure to produce extremely high-strength joints that are virtually defect free. Friction Stir Welding transforms the parent metal from a solid to a plasticised state. This occurs during a process that involves mechanically stirring the materials together to form a high-integrity, full-penetration welded joint.

Incorporating the brands of Binns & Berry, Crawford Swift, Holroyd and Holroyd Precision Components, PTG has established itself at the forefront of high precision machine tool design, build and supply. The PTG range includes heavy duty lathes, deep hole drilling machines, Friction Stir Welding (FSW) machines, ultra precision grinding machines for rotor, thread and gear operations; rotor milling machines and special purpose machine tools for the manufacture of precision components. Industrial sectors served range from aerospace, medical and mould tool & die to marine, power generation, mining, oil & gas, steel, high end and heavy automotive.

Successful projects
The award for Sandvik Coromant arrives after the completion of several successful projects to reduce cycle times and boost both productivity and profitability. In 2014 a total of seven projects with projected savings for Volvo were identified and documented. Overall these projects have not only improved quality and reduced downtime, but extended tool life to deliver a 39.8% saving in tooling costs.

By way of example, Sandvik Coromant recently proposed the testing and implementation of CoroMill® 5B90 to machine the combustion face of cylinder heads and overcome excessive burr. The solution delivered three times greater tool life, far fewer burrs and much quicker tool set-up.

Close co-operation
Working in close co-operation with the Volvo Cars engineering team, other tooling projects completed in the past 12 months include the implementation of the CoroTurn® SL system of modular adaptors and exchangeable heads to facilitate quicker tool change; new insert geometry for grooving camshafts that increased tool life from 125 to 500 pieces; new inserts for crankshaft machining that led to longer tool life and shorter cycles; and a new grade and geometry for a boring tool that increased tool life and reduced downtime due to fewer tool changes.

Moving forward, current projects involving new tooling concepts include cost reduction and process security for cylinder boring, and an increase in quality and tool life for wheel hub spline milling. Sandvik Coromant is also delivering support in upgrading tool holders that will allow the next generation of crankshafts to be accommodated.

20-year partnership
Sandvik Coromant has been a committed partner to Volvo Cars for more than 20 years, striving continuously to identify ways to optimize tools, machining methods and thereby, end results. The company has established a long partnership with the engine manufacturing plant in Skövde and the component manufacturing plant in Floby, although support also extends beyond Sweden. For instance, Sandvik Coromant recently helped with the transfer of knowledge on tooling for machines at a brand new facility in China.
