Medical Machining Made Easy



There is no need to deal with multiple set-ups and manual repositioning of the workpiece, with the resultant degradation of part accuracy, when 5-axis machining allows you to approach the workpiece from all directions in just a single set-up, said an Expand Machinery spokesperson.

GenMill 5X-4

Expand Machinery offers the GenMill 5X-4, which features a 4" diameter tilting and rotating worktable with zero-backlash roller gear cam operation for repeatability. "It machines materials ranging from titanium and stainless steel to Kovar and Inconel to produce body implants, surgical instruments or a myriad of other medical components. The GenMill 5X-4 making 5-axis machining more affordable than ever," said the spokesperson.

The 5X-4 features a 12,000 RPM 7.5 HP dual-ground, dual-contact BIG-PLUS SPINDLE and offers 6,000 RPM tapping capability. The drum-style tool turret provides for 21 tools in BT#30 holders and changes tools in 1.6 seconds. The quick tool change time coupled with rapid traverse rates of 2,362 IPM make for enhanced production efficiency. "The preloaded cross-roller bearing guideways provide greater stiffness, rigidity and load carrying capability than other guideway systems offer, resulting in better surface finishes and improved tool life," said the spokesperson.

The spokesperson continued, "To obtain high productivity in 5-axis machining, paramount consideration has to be given to a CNC control and drive system that has the speed and responsiveness necessary to optimize machine performance. The GenMill 5X-4 is paired with the Mitsubishi M80 high-performance CNC controller featuring a 64-bit RISC processor. It offers a 135,000 block-per-minute processing speed, a 1,350 block look-ahead capability and a massive 32 GB solid-state data server, making it one of the fastest controls in the industry."

20 mm GENTURN Hybrid Swiss CNC Lathe

Expand Machinery offers production efficiency by completing complex parts in one seamless operation. The GENTURN CNC Swiss lathe series, which includes the twin-spindle GENTURN SL-20Y2 8-axis 20 mm Swiss lathe, addresses the need of getting work up to O3/4" done efficiently in one operation, with all of the axial and radial milling features accurately timed and deburred. "The only way to be really competitive in the modern machining world is to get the work completed without building accuracy-compromising fixtures for follow-on operations and tying up multiple machines and operators," said the spokesperson.

Dental and precision medical parts for screws, shafts, standoffs, inserts and other components are suitable candidates for the SL-20Y2 machine. The GENTURN SL-20Y2 can be operated with or without a guide bushing so operators can make the best choice of operating modes. The 10,000 RPM main spindle is powered by a 5 HP spindle motor. The 5 HP sub-spindle turns at 8,000 RPM. A total of 30 toolholders are standard with the basic machine, of which eight tools are driven, and feature ER-16 collet spindles. The main spindle can bring 17 tools to work on the part, and the sub-spindle can utilize 13 tools in the basic machine configuration.

Many tooling options are available to address the specific tooling needs of each workpiece and to increase the overall tool count. Standard features include a high-performance C-axis with 0.001° resolution on the main and sub-spindle for accurately timed axial and radial milling features. A parts catcher and parts conveyor are provided to facilitate the mark-free removal of valuable parts from the machine. A cut-off confirmation sweep-arm switch is provided to ensure that the part is properly separated from the barstock curing cutoff. Cutting oil flow-confirmation monitoring is provided to confirm that the cutting oil is properly lubricating the cutting tools. A cutting oil chiller system is included to maintain thermal control of the cutting oil for consistent machine accuracy. All Expand Machinery machines are built in a modern ISO certified factory in Taiwan.

Expand Machinery also provides a 5-axis milling machine with a 12" platter, as well as an extensive line of 3-axis milling centers from 24" x 16" up to 100" x 39" and drill/tap centers. The turning roster consists of CNC Swiss multi-axis CNC turning centers from 20 mm to 52 mm, and the Ganesh lineup of manual and CNC toolroom machines.
