Alphacam accuracy helps swiss watches keep perfect time

Production engineering solutions required by many leading Swiss watch-makers are installed in their CNC machines when they buy them. Bumotec, based in the tiny Swiss village of Sâles just a few miles from the Prealp mountains, pride themselves on not simply producing standard machines.

Almost every one they supply has been trialled by manufacturing the customer’s parts on it, and comes complete with the Alphacam CNC programs for those parts. All Bumotec machines are adapted to provide specific solutions addressing the individual needs of each customer, ranging from 3-axes to 38-axes, using Fanuc controllers for machines with up to 25-axes and Num controllers for those above 25.

On demand solutions
A number of specialist macros for the watch-making industry have been developed by Alphacam’s Swiss reseller MW Programmation. They include machining perlage (aspects of decoration such as circles, spirals and linear patterns); sequential numbering to automatically generate serial numbers of pieces without needing to change the NC program manually; palpage, which defines exact placement of the piece before machining; and diamond settings, allowing parameters of the amount, size, and space between stones to be input. MW Programmation work closely with Bumotec on every aspect of their customers’ needs, including the macros, post processors, training and a technical support hotline. While Bumotec provide their customers with initial training on Alphacam if they need it, MW have two training rooms at their headquarters in Malleray, in northern Switzerland, where they can tailor both basic and advanced courses to individual customers’ requirements.

Partnership for the customer’s success
Director Marcel Weber gives an example of where they worked directly with a Bumotec customer to address their need for machining parts by following the profile with a specific tool to create a chamfer. “As the main spindle doesn’t have a rotation frequency it had to be angular controlled, so we developed a macro to control this all the way along the part.”

New waveform 3D roughing strategy
A recent addition to Alphacam’s functionality is a new Waveform 3D Roughing Strategy, which Marcel Weber says will be of particular benefit to the watch industry.  “The new high speed machining technique maintains a constant tool cutting load by ensuring consistent tool engagement into the material. The tool moves in a smooth path to avoid sharp changes in direction, maintaining its velocity, dramatically decreasing the machining cycle time.”

The missing link

Ehn & Land is one of the most successful sales organisation in Scandinavia in the field of microtechnology and high precision machining. Since 2012 the CEO, Ulf Karaker, wanted to broaden his horizon and has successfully created a new sister company, Ehn & Land Asia Pacific (and another one in 2006: Ehn & Land international based in Switzerland).

The 1950’s family owned company has built its success on their motto: “Our customers’ success is our success”. Mr. Karaker says: “We believe in establishing long-term relationships with our customers. Our goal is to be a natural part of their day-to-day business so that we can provide them with solutions that increase their competitiveness and profitability”.

Asia is growing… with or without us
“A lot of European companies are working in Asia now and they sometimes miss a global partner like us to help them finding and building the best manufacturing solution” says Ulf karaker. He adds: “Dietmar Kogler our CEO for Asia-Pacific has a good track record in Asia and many companies know that they can rely on him to help them”. Nowadays the company is officially representing about 10 Swiss and European companies providing high-end tooling and material and is involved in helping Swiss machine-tools manufacturers in doing business in south-east Asia. “The market is there and companies are more and more demanding of high quality solutions. We are building the Ehn & Land brand in these countries and we are convinced we can play a major role in the success of our customers there” says the CEO.

New business model
Ehn & Land International buys machines, overhauls them and sells them like new machines, with guarantee and even with training and service if needed. The result is clearly not a mere second-hand machine business but a completely new economic model, like a missing link between second-hand machines and new ones.

The machines proposed by Ehn & Land International are high-end machines only (automatic lathes and grinding machines only) and can be delivered worldwide. The CEO says: “Our business is to be with our customers day after day to help them solve their problems and for that we know we want to stick to our concept of high quality machines”. And the business starts to be successful; the company has already sold a few machines in Europe and overseas. Questioned about the relation with machine-tools builders and the competitive aspects on this business model on them, Mr. Karaker explains: “We are not in competition with them, we mainly aim to help people in our network to do business and our volumes are small. Therefore we can help machine-tools builder too”.

New versatile high performance drill

CoroDrill 460-XM is a multi-application, high-performance drill that can be used across a wide range of materials. This drill provides high capacity utilization, flexibility and versatility. With one drill for all materials, stock holding can be reduced and greater machine flexibility is offered leading to reduced set-up time.

Sandvik Coromant introduces the new CoroDrill 460-XM, a new multi-application, high performance drill for use across a wide range of materials.

The CoroDrill 460-XM is made from micro-grained carbide for an excellent combination of hardness and toughness, resulting in high wear resistance and longer tool life. The coating has a special finishing treatment to reduce coefficient of friction.  The strong web design provides excellent cross-sectional strength that, combined with increased flute volume, enhances chip evacuation. The point angle of 140º is ideally suited for multi-application drilling, with good centering capabilities and low thrust force design.

The drill comes in a standard diameter range of 3–20 mm (0.118–0.787 inch) in drill lengths; 2–5 × drill diameter (DIN 6537 K and DIN 6537 L). Achievable hole tolerance: IT8–IT9 and is available with internal and external coolant.

Easier multi-tool use for sheet metal

New developments in the 2013 release of the sheet metal CAD/CAM software, Radan, provide considerably improved support for multi-tools, meaning they are much easier to use.

Radan General Manager Chris Aston says the traditional way of setting up multi-tools in the machine system data file is cumbersome and time-consuming. However, a major concept change in Radan 2013 provides considerable support for multi-tools. “We take the principle that a multi-tool is a tool, not a turret, which has implications as to how multi-tools are deployed by Radan and configured and manipulated by users. In Radan 2013 multi-tool configurations are deployed by taking the ‘variable (to buy)’ for the machine tool in question”.

“For example, a configuration for a Trumpf machine will have the definitions – the shape and number of stations – of all multi-tools the customer may purchase for their machine tool, without allocating it to a tool station at that time. This is less work-intensive and more flexible than the traditional system of always allocating a multi-tool to a station.” The combination of all enhancements in Radan 2013 provides greater automation while still giving the user manual options if required. It contains key enhancements to the navigational tools, increasing accessibility to functions; along with improved integration of Radband; and the addition of colour making it easier to identify parts, both pre and post production.
Chris Aston says: “Extensive research and ongoing development ensures Radan constantly enables users to gain the absolute maximum performance from their CNC machines and the CAM process for sheet metal, maintaining a competitive edge.”
