The Mikron MILL S 200U designed for medical device manufacturing.

The MILL S 200 machining centre series from GF Machining Solutions is available in three- and five-axis (full simultaneous) versions for machining small, complex medical components such as stainless steel denture bars and orthopaedic implants.

The machines’ compact size allows them to be installed in facilities such as dental laboratories and other environments where floor space is at a premium.

The machines deliver excellent part surface finishes, as fine as Ra 0.05µm, thanks to linear motor technology (on the machines’ main axes) and direct-drive motors (on the 5-axis machines’ B- and C-axes). A high-speed 50,000rpm (HSK E32) Step-Tec spindle also ensures fast processing speeds as well as enabling precise part details and super fine surface finishes to be achieved. (A 20,000rpm high-torque spindle option is also available as an option).

To increase the machines’ productivity, MILL S 200 machines can be supplied with high-productivity APC systems (12/14/20magazines) with either System 3R or Erowa interfaces which enable the machines to run unattended 24/7.

The machines also feature the last Heidenhain Control iTNC 640), and are equipped with a range of advanced SMART technology modules improve process efficiency, precision and reliability. The SMART machine modules automatically monitor spindle vibration, calibrate machine geometry and can transmit process status messages to the operator’s mobile phone via its RNS (Remote Notification System).

With all GF Machining Solutions’ high-speed milling machines careful attention is devoted to damping and thermal stability – both pre-requites for high precision and surface finishes.

The Mikron MILL S 200 machines have a polymer concrete base, linear (recirculating) roller guides (35mm) on the machines’ X-,Y-and Z-axes, and rigid linear direct drives. All the machines’ direct drives (X- Y-and Z-) for 3-axis models and X-, Y-, Z-, B- and C-axes for 5-axis models) are water-cooled to ensure thermal stability.

For increased flexibility the machines are equipped with a 30, 60 or 150 position ATC (disk magazine) that features a reliable and quick double-gripper change system and a C-T-C tool changeover time of 4 seconds.

To increase the application potential of the machines, high-efficiency dust extraction systems (i.e. when machining graphite) can be specified.
