EDM builder enters high speed milling market

Having pioneered the use of linear motors in tooling machines, and experience with more than 6,000 linear EDMs, Sodick has developed a high speed milling machine for mould and die work.

Having pioneered the use of highly dynamic linear motors in tooling machines, and on the basis of its experience with more than 6,000 linear EDM machines, Sodick presented a new generation of high-speed processing centres with linear motors on all axes at EMO.

Precision in the micron range, high-speed milling with up to 1G acceleration, extremely fast travel speeds, as well as maximum stability and precision - these are the primary characteristics of these innovative machines, with which Sodick is heralding a new era in the milling industry.

Whenever mould and die production calls for milling with maximum precision and surface quality, Sodick recommends the new high-speed MC430L and MC630L processing centres.

These form the perfect alternative to existing machine concepts for applications ranging from hard-cutting of complex work-pieces to high-speed milling of filigree electrode geometries.

Linear drives on all axes, direct measuring systems, acceleration up to 1G, (virtual) precision in the nano-realm as well as spindle speeds of up to 40,000 rev/min are the key performance data.

To ensure this high level of dynamics and precision can be applied optimally to the work-piece, the machine bed features a cast construction for rigidity and stability.

This is evidenced by machine weights ranging from 5,800kg for the MC430L to 7,000kg for the MC630L.

These high-speed centres also feature state-of-the-art control technology based on Windows and the Sodick Motion Control closed regulating system.

Impulses from the direct measuring system are sent via the CNC core in real time, without detours, directly to the drive regulator.

No compromises were made when designing the tool holder either; Sodick consistently relies on the HSK E holder, with proven stability under high-speed conditions.

Tools are replaced from a magazine with 16 slots (optionally 45), which is just as easy to access as the compact workspace in this thoroughly impressive innovation in the milling field.
