VDP – a unique product development offers higher performance in metal-cutting machining

System 3R is constantly working on improving the performance of its products, not least with a view to finding new fields of application. Resting on our laurels is not part of our corporate philosophy. The development of VDP - vibration-damped palletisation - is an example of advanced development which is going to set new standards in metal-cutting machining.
The typical machining system is a closed circle where the elastic structure broadly consists of three components - a machine tool, a cutting tool and a workpiece clamping system - which together dictate the stability of the system. The quality of the manufactured product and the capability of the machining process depend largely on the dynamic stability of every component of this structure.
Ever more stringent demands on metal-cutting machining - new materials, better surface finish, closer tolerances - have made the vibration problem more and more urgent. System 3R saw an opportunity here to improve the entire machining process by improving the dynamic properties of their pallet system.
"Our vibration-damping pallet systems are effective over a broad range of frequencies. Just as effective in conventional milling as in high-speed milling", says Dr. Amir Rashid, in charge of research and development. "During machining, the parameters change all the time as a function of the type and size of the workpiece, the material, the cutting data - and not least - on the way the mass of the workpiece changes as material is removed."
"System 3Rs pallet systems have always been ahead in terms of performance. The new, integral vibration damping has a marked positive effect on productivity, quality and profitability."
The VDP range includes both manual and automatic chucks - Macro, MacroMagnum and Dynafix - which:
- improve surface finish -reducing the need for finishing.
- reduce tool wear - lengthening tool life
- allow machining with a higher removal rate - giving shorter lead times.
- reduce wear on the machine spindle - cutting the maintenance costs of the machine.
- reduce noise level - improving the working environment.
"Several years' work have been invested in this project, including development and testing at the Department of Production Engineering at the Royal Institute of Technology, Stockholm (KTH ), and the Fraunhofer Institute for Production Technology in Aachen. Our aim is to lead - not follow - developments in machining technology and meet the demands of our customers all over the world. A sign of VDP's excellence is that several major machine manufacturers at the latest trade fairs have had VDP on their machine tables to show the superiority of their machines", Dr. Rashid concludes.
