GF Machining Solutions continues to provide value and efficiency with its MIKRON HEM 500U milling machine as part of an automated multi-machine manufacturing cell capable of full lights-out operation. The machine’s special rotary tilting table makes it possible for manufacturers focused on accurate and reliable parts production to cost effectively achieve high-performance 5-axis machining for single-setup part processing.
According to Gisbert Ledvon, director of business development for GF Machining Solutions in North America, the company successfully achieved its price/performance goals with the HEM 500U thanks to its highly experienced and forward-thinking design and engineering teams. “This machine proves it’s possible to maintain our deeply rooted expertise in 5-axis machining at a new lower pricing level.”
Ideal for cutting parts from aluminum alloys and steel, the HEM 500U features a highly dynamic 12,000-rpm ISO-B40 spindle and 30-tool magazine that provides a 2-second chip-to-chip time for high-speed continuous milling operations and increased spindle uptime. Additionally, a 20,000-rpm spindle and 60-tool changer are available.
A trunnion table measuring 19.7″ in diameter and accommodating workpiece weights up to 440 lb, tilts -65/+110 degrees in the B-axis and rotates 360 degrees in C for 3 + 2 machining as well as 5-side positioning. Axis travels in X, Y and Z measure 19.7″, 17.7″ and 15.7″, respectively, while a distance of 5.9″ between the machine spindle nose and rotary table surface allows for ample maneuverability around workpieces.
The highly robust HEM 500U works well under a variety of working conditions. Its C-frame structure supports a cross-sledge for the transversal X- and Y- movements. All three linear axes are located on a sturdy block that houses the B-axis. The vertical Z-movement, which contains the inline spindle, mounts to the rigid Y-axis column.
The HEM 500U relies on a Heidenhain iTNC 530 control for quick and reliable machining. This versatile, workshop-oriented control for 5 (3+2)-axis machining features an integrated digital drive control with integrated inverter, enabling it to produce a highly accurate workpiece contour while machining at high velocity. The HEM 500U also comes equipped with Smart machining modules that provide advanced levels of monitoring critical to the production of aerospace and defense parts.
Featuring a small footprint, the HEM 500U is ideal for tight setup areas in small job shops and large production plants. The attention to the ergonomics of the machine’s design allows for easy access to workpieces. Its highly accessible structure makes it possible to load and unload workpieces using a forklift as opposed to a crane.
In developing the MIKRON HEM 500U and the entire High Efficiency Machining (HEM) Series, which also includes the HEM 800, HEM 1000 and the HEM 1200, GF Machining Solutions sought to redefine the performance and quality standards in the vertical machining center category by creating cost-effective solutions that place the company’s best technologies into modern, reliable and ergonomic designs.
