The latest high-performance MIKRON HPM 450U milling solution from GF AgieCharmilles boasts a new torque rotary/tilt table for unencumbered, interference-free five-axis machining and offers highly efficient spindle options well suited for all machining applications from micro to macro.
According to Gisbert Ledvon, business development manager for GF AgieCharmilles, the MIKRON HPM 450U is also a powerful solution for universal, automated production as it perfectly combines dynamics and stability. It easily adapts to suit a variety of customer requirements, offering impressive machining from simple drilling to complex five-sided and simultaneous five-axis machining processes.
The MIKRON HPM 450U features a sturdy and compact design with a large work envelope. Maximum X-Y traverse paths measure 23.62" and 17.2" respectively, with a Z-axis that provides 17.72" clearance between the table surface and spindle nose. Furthermore, the machine has a fast rotary table speed of 140 rpm and an ample tilting range of -120/+45.
The machine's high-performance Step-Tec spindle is available in a 12,000-rpm version with an ISO 40 taper for conventional tooling technologies and programs or in a 20,000- rpm version with an HSK-A63 taper for machining a wide variety of materials. Both versions offer a vector control for full torque in lower speed ranges, a highly stable ceramic hybrid spindle bearing and spindle casing cooling using a controlled internal coolant system that maintains consistent temperatures throughout the entire work process.
Thanks to its various tool magazine sizes, the MIKRON HPM 450U accommodates everything from single-piece production to the mass production of complex workpieces. An internal tool changer, which integrates into the machine's base, has a storage capacity of up to 60 tools. An external circular magazine increases that capacity to 220 tools. Coupling the external magazine with an optional automatic pallet-changing magazine creates a flexible manufacturing cell capable of unmanned, lights-out production.

- clearance
clearance
Space provided behind a tool’s land or relief to prevent rubbing and subsequent premature deterioration of the tool. See land; relief.
- coolant
coolant
Fluid that reduces temperature buildup at the tool/workpiece interface during machining. Normally takes the form of a liquid such as soluble or chemical mixtures (semisynthetic, synthetic) but can be pressurized air or other gas. Because of water’s ability to absorb great quantities of heat, it is widely used as a coolant and vehicle for various cutting compounds, with the water-to-compound ratio varying with the machining task. See cutting fluid; semisynthetic cutting fluid; soluble-oil cutting fluid; synthetic cutting fluid.
- gang cutting ( milling)
gang cutting ( milling)
Machining with several cutters mounted on a single arbor, generally for simultaneous cutting.
- milling
milling
Machining operation in which metal or other material is removed by applying power to a rotating cutter. In vertical milling, the cutting tool is mounted vertically on the spindle. In horizontal milling, the cutting tool is mounted horizontally, either directly on the spindle or on an arbor. Horizontal milling is further broken down into conventional milling, where the cutter rotates opposite the direction of feed, or “up” into the workpiece; and climb milling, where the cutter rotates in the direction of feed, or “down” into the workpiece. Milling operations include plane or surface milling, endmilling, facemilling, angle milling, form milling and profiling.
- work envelope
work envelope
Cube, sphere, cylinder or other physical space within which the cutting tool is capable of reaching.
