Tough centring points expand the range of applications

The Komet Group is continually working to further develop its range of tools, which will afford the user even greater gains in terms of productivity. The results of the latest efforts are a choice of two new centring points for the Komet Kub Centron Powerline core bit drill which, with its multiple cutting edges, enables high feed rates and, as a result, short production times.

blogB01_KOMET_KUB-Centron-Powerline_Explosion
The centring point of the Komet Kub Centron Powerline is available for various materials and machining situations. It sits in a core bit, which has two four-edges indexable inserts.

The points that have been available until now are standard carbide points, which can be used universally. However, for machining certain materials that require, for example, low cutting speeds, or for unstable situations such as working on lathes, where there is a certain degree of axial misalignment, tougher cutting tool materials offer a number of advantages.
This is why drilling specialists at Komet have come up with a second centring point which, with its special ground section and coating, is optimised for use with stainless steels. The substrate consists of a carbide that has predominantly been used for the purpose of wear protection in the past, and is much tougher than the carbide grade originally used. This makes the new centring point suitable for working situations in which vibrations and minor impacts are likely to occur, as well as for materials that are difficult to machine and require cutting speeds of between 30 and 80 m/min. For large tool diameters where the centring point is subjected to even lower cutting speeds (between 10 and 30 m/min), the Komet Group offers a third centring point, which is made from HSS. It too has the special ground section for stainless steels and the corresponding coating.
The centring point is a crucial element of the Komet Kub Centron Powerline. It guides the tool precisely along the drilling axis, ensuring dimensional accuracy, straightness and outstanding process reliability at drilling depths of up to 9xD. The core bit has two or, depending on the diameter, more than two Quatron indexable inserts, which provide a high level of stability and optimal chip evacuation. The cutting distribution on each side allows short chips to be produced even when using materials that are extremely difficult to machine. The four cutting edges per indexable insert, various substrates and coatings and tailored topographies for excellent chip control, soft cutting action, etc. allow for a long tool life and help make machining cost effective.

GrindTec 2016: Growing interest from Asian companies

The interest shown by Asian suppliers of grinding technology is growing visibly. More and more companies from China, Korea, Japan and Taiwan see the GrindTec as the perfect platform for the presentation of their products. And the amount of space they need for their stands is also growing. The large manufacturers from Germany, Italy and Switzerland also require more space for their stands, which are becoming more and more elaborate.

blog0227_grt_02

At present the project management has received about 470 registrations, and expects to soon reach the 520 exhibitors of the last, so far biggest GrindTec in 2014. At any rate it is certain that the GrindTec will grow overall: The organisers AFAG Messen und Ausstellungen GmbH have planned 42,000 m² for the GrindTec 2016.

All the leading grinding technology companies will be there in Augsburg

The most important companies from this sector have registered long ago, and many of them have considerably enlarged the space booked. For a large number of them the GrindTec is the most important trade fair – this is where they achieve top results, as most recently during the GrindTec 2014: 75 % of the exhibitors assessed their participation as “very good” or “good”, and a further 17 % were “satisfied”.

Hall planning mainly concluded

Weeks ago the planning of the exhibition halls began: The largest stands have been allocated their positions, and smaller stands are available in parts of the halls, although these, too, are slowly filling up too. All companies, which are interested in exhibiting, should contact the project management without delay, in particular if they have any special requests with regard to their positions. The documentation for participants can also be downloaded from the homepage of the GrindTec at www.grindtec.de. The project manager reminds all participants that it is very important to name all products, which are to be exhibited, in your application form. Without this information it will not be possible for you to participate in the GrindTec 2016.

Interplastica 2016: Arburg demonstrates automated production

At the Interplastica, to be held in Moscow from 26 to 29 January 2016, Arburg will be presenting a practical example of production-efficient, cost-effective automated production. Visitors will see a Golden Edition series hydraulic Allrounder and an integrated Multilift Select robotic system produce a toy buggy and assemble it ready for use in a single process step.

An Allrounder 420 C Golden Edition will use a family mould to produce all components in a single step at the Interplastica 2016. A Multilift Select robotic system will assemble the individual parts to produce the finished buggy.
An Allrounder 420 C Golden Edition will use a family mould to produce all components in a single step at the Interplastica 2016. A Multilift Select robotic system will assemble the individual parts to produce the finished buggy.

This system is an excellent example of how injection moulding companies can increase their efficiency in a targeted way, competitively producing plastic parts at minimal unit costs. The technical features of the exhibit are precisely tailored to the market needs of Russian plastics processing companies.

Toy buggy produced in a single injection moulding cycle
Arburg will demonstrate the high quality, automated and cost-efficient manufacturing of standard products based on the example of a toy buggy. In addition, the exhibit will provide proof of the performance capability of the proven Golden Edition series. An Allrounder 420 C Golden Edition with a clamping force of 1,000 kN and a size 290 injection unit will use a 1+1+2-cavity family mould to produce all parts in a single step. The cycle time is around 30 seconds.
Following the injection moulding process, a Multilift Select robotic system removes the sprue and the four individual parts – the roof, chassis and two axles with overmoulded wheels – and assembles these on an assembly table to produce the finished buggy.

Energy-optimised Allrounder
The Allrounder is equipped with the Arburg productivity package. This comprises the Arburg energy saving system (AES) with variable speed pump drive and water-cooled drive motor. This makes operation with two control pumps even more economical, allowing two simultaneous movements to be realised. The benefits of the productivity package are the reduction of the energy requirement by up to 20 percent, the shortening of the dry cycle times by around five percent and the minimising of emissions.

Cost-efficient entry-level automated production
The Multilift Select is the entry-level model among the linear robotic systems from Arburg. It has servo-electric drives and is fully integrated in the Selogica machine control system. For the operator this means: only one data set, a familiar approach during programming and perfect synchronisation of robotic system and machine. In addition, the teach-in function means that the Multilift Select is extremely easy to program.
This configuration allows companies to take their first steps in automated injection moulding production thanks to the proven technology and the ease with which the system can be programmed and operated, as well as the optimum price/performance ratio.

XL-80 laser functionality extended to perform diagonal tests

Renishaw launched a Linear diagonal measurement kit at EMO 2015. Laser diagonal tests can be used to measure diagonal positioning and reversal errors in accordance with B5.54 and ISO 230-6 standards. The ISO 230-6 standard states that diagonal displacement tests allow the estimation of the volumetric performance of a machine tool. The new kit is quick and easy to set-up, is easy to align and allows fast data analysis to international standards.

The Renishaw Linear diagonal measurement kit provides everything needed to perform laser diagonal tests with an XL-80 laser interferometer system. The kit is designed for quick and easy set-up, with purpose-built fixturing that’s magnetically mounted to the machine tool bed and holds the XL-80 and optical accessories. A beam steerer and swivel mirror (attached to the plate) then provide a very controllable way to align the laser beam with the machine diagonals.

A key advantage of using the new kit to mount the XL-80 and optical accessories on the machine bed is that after measuring one machine diagonal, the plate can be moved to the other body and face diagonals with easy realignment.

As well as the hardware system, Renishaw also provides software to easily carry out laser diagonal tests. XCal-View provides convenient data analysis for laser diagonal tests, in accordance with ISO 230-6 and B5.54 standards. The application can take the data from laser diagonal tests and provide a report that shows the key errors and gives a graphical display of the results.

600 UK fully committed to Engineering in Education at MACH 2016

As part of their ever increasing support to engineering training, 600 UK are investing heavily in MACH 2016 to profile their class leading products. These world famous brands, primarily manufactured in the UK, are supplied to education worldwide.

"Engineering in Education", - training
“Engineering in Education”, – training

Not only will 600 UK exhibit benchmark Colchester and Harrison lathes in Hall 5 and Pratt Burnerd Chucks in Hall 4, but they have also invested heavily in the MACH Learning and Development: Apprentices at Work Zone.

Within this zone, 600 UK will exhibit the world’s number one manual education lathe, the Colchester Student, alongside the exciting new Harrison EziTurn electronic lathe. The EziTurn has been designed specifically for education and training, effectively bridging the gap between manual and CNC turning, which for some students, can be a daunting leap.

Further increasing their presence, 600 UK will also promote the Clausing range of milling, drilling, sawing and grinding machines. This, new to the UK, range of machine tools has already enjoyed huge success in North America, the Middle East and Australasia. The Clausing brand of non-turning machines means that 600 UK can further meet the ever increasing turnkey requirements demanded by colleges and universities for the highest quality machine tools required to meet the needs of the engineering curriculum.

“Colchester and Harrison have always focussed on education and training when developing their lathe ranges, where they have always been considered the benchmark. However, it is imperative that they are manufactured robustly to also meet the demanding standards required within an industrial setting.” says 600 UK Managing Director, Mike Berry.

“MACH has always had a great worldwide reputation for industrial and educational oriented products which continues to grow apace. We firmly believe that 600 UK, as manufacturers of some of the best educational engineering products in the world, should be there to support the MTA and the MACH exhibition”.

MTA CEO James Selka DL, said “We are grateful to 600 UK for throwing their support behind MACH 2016. Education and training is integral to the continued growth of our industry and having high quality equipment that is specifically designed as teaching aids working on site will further demonstrate that advanced engineering is an accessible career choice.”

Delcam’s FeatureCAM used to produce 815 mm steel part on Hermle mill-turn

A new video from Delcam demonstrates the improved metal-cutting possibilities on a Hermle machining centre with integrated turning capability when the machine is fitted with the latest TNC 640 contouring control system from Heidenhain and programmed with Delcam’s FeatureCAM feature-based CAM software.

Almost 1 tonne of steel was machined away to produce this part on the Hermle machine at the NAMRC
Almost 1 tonne of steel was machined away to produce this part on the Hermle machine at the NAMRC

The process starts with a 1.6-tonne EN8 steel billet measuring 815 mm in diameter and includes a complex series of machining operations that, in total, removed 935 kgs of material. It demonstrates clearly the improved productivity possible with the latest equipment and machining methods, through increased speed and accuracy, reduced idle times and longer tool life.

The filming was undertaken during two seminars at the NAMRC (Nuclear Advanced Manufacturing Research Centre) during May. Jointly sponsored and organised by Heidenhain (GB) and Geo Kingsbury, sole agent for Hermle machines in the UK and Ireland, the event was also supported by tooling supplier Seco and workholding firm, Schunk as well as Delcam.

Many features of the machine and control combination are shown in the video, including ‘A-axis Turning’, which allows the trunnion to be continuously positioned at any angle while the component on the table is rotated for turning using a fixed tool in the spindle. This simultaneous interpolation gives improve cutter access and allows shorter turning tools to be used for more stable machining.

Another attribute demonstrated was programmable ‘Adaptive Feed Control’ within the TNC 640 control, which continuously adjusts the feed rate to keep the spindle load constant as the milling cutter moves into different parts of a cycle. When used together with Delcam’s Vortex high-efficiency area-clearance strategy, AFC can significantly shorten cycle times as the full depth of the cutter flutes can be used rather than just the bottom few millimetres, leading to faster metal removal and longer tool life.

Finally, a series of five-axis finishing operations are shown, including swarf machining and deburring by edge profiling. All these strategies can be checked on the computer using FeatureCAM’s full-machine simulation to ensure that they will run safely on the machine.
