MORE CASE STUDIES
When RSM SA was formed in 1998 to produce high value components for the watchmaking industry, nobody at the company could foresee the astronomic growth and success the business would achieve in such a short duration.
Based in La Chaux-de-Fonds, the company is positioned in the heartlands of the Swiss watchmaking and precision industry region. It has developed from a small machine shop with one machine in 1998, to a 20 employee business working out of a 1000m/sq building with over 40 machine tools.
Discussing the conception of the business, RSM SA company director, and Mr M Magistrini comments: “When we decided to start the business producing high value parts for watches and watch bracelets we were looking for a machine that could fulfil our requirements in terms of creating links and attachments. The Almac FB1005 met our technical requirements although I didn’t have a particularly high opinion of the cnc machines. However, during the company start-up Almac supported us both technically and financially and I don’t regret making this choice – as we now have 14 of these machines plus 3 Almac machining centres.”
RSM wanted a machine with 4 to 5 axes that enabled the company to produce complex high value parts with great autonomy and the Almac FB1005, fitted the company’s needs. With a feed of up to 5m/min in X, Y, Z and W stroke and rapid advance of 12m/min with a spindle speed of up to 12,000rpm, the FB1005 has a clamping diameter of 1 to 13mm making it ideal for machining simplistic as well as complex components in this diameter range.
Now part of the Tornos Group, Almac machine tools have a multitude of benefits, as Mr Magistrini says: “When I chose the first FB1005 I was won over by its set-up. The machine is sound, accessible and pleasant to work with. In addition, it is quick and easy to set-up and of course reliable with good repeatability and quality. On some of the machines the counters are hitting 70,000 hours of operation with more than a million parts produced with cycle times from 3 to 10 minutes per part. The machines work to tight tolerances at full capacity with all axes and tools mobilised, so the Almac machines are perfectly qualified for machining our parts.”
Operating in such a high volume production environment, the reliability and servicing of the Almac machines is key to the success of RSM, as Mr Magistrini continues: “We always expect the best in terms of service as we simply cannot tolerate machines that are not running. And on this front the Almac machines have proven very reliable. If there has ever been an issue that needs a resolution, the service staff are on-site almost immediately attending to the issue.”
Looking to the current position of RSM and its outlook for the future, Mr Magistrini continues: “Our vocation is and always has been to produce high value added parts whilst increasing our expertise. The competition is global and only staying ahead at this level will enable us to remain competitive. The parts we produce are increasingly technologically advanced whether for the watchmaking, medical or other industries.”
With respect to the Almac FB1005 fulfilling this need, the machine has been designed to guarantee precision with an X-axis slide guided on pre-stressed rails working with a ballscrew. The slide supports the vertical Y-axis that is formed of a rigid cast iron prism on which a rectangular sleeve moves. Guided on four pre-stressed rails, this is also moved by a ballscrew and allows a unit equipped with frontal lateral or vertical spindles to be fitted.
However, Mr Magistrini is keen to stress that the machine tool alone cannot achieve such success by concluding: “Added value is very dependent on the qualification of personnel. Expertise in the use of tools, feeds, machines and processes all combine to strengthen the competitiveness of our company.”
