Vertical Lathes
Vertical turning lathes stand apart in the performance of operations like hard turning and grinding. They provide a stable base for large workpieces, thanks to the cast iron body and large spindle diameter. A cross rail provides added support to the workpiece during operations.
Key features like ball end mills, vertical machining centers and automatic pallet changers facilitate versatility and productivity. Equipped with precision-positioning equipment, vertical lathes excel at handling intricate tasks.
Gantry & Portal Milling Machines
Our gantry and portal milling machines offer precision and quality for large-scale operations. They are equipped with large CNC controls for easy program control and remote diagnostics. With features like high rigidity, automatic tool changer and vertical bridge mill, these machines are redefining the norms of large-scale machine transfer, installation and operations.
Gantry milling machines utilize a moving crossbeam that spans the workzone on dual side supports, providing strength and versatility. The spindle head travels on the gantry to position tools anywhere on the X, Y and Z axes, allowing for efficient 5-sided machining. Our large CNC gantry mills from top brands like Hexram and Huron give you the flexibility and accuracy to machine extremely tall, heavy parts.
Portal milling machines have a stationary spindle head mounted to robust twin columns, while the worktable travels along the Y-axis between them. This rigid construction bears heavy loads while minimizing vibration. The inverted vertical milling design provides superior chip management over the workpiece. Our portal mills from Hexram feature optional rotary tables for simultaneous 5-axis cutting suitable for aerospace components or impellers.
Horizontal Mills
Horizontal milling machines are perfect for tasks demanding high precision and power. They are equipped with a robust spindle unit and ball screws for perfect alignment and accuracy.
The automatic tool changer feature enhances the productivity of these machines while ensuring accuracy at all times. With a large working enclosure, horizontal mills can handle larger workpieces.
Multiprocess Machines
Multiprocess machines fuse various functions into one to deliver efficient and precise results. Equipped with an automatic pallet changer and automatic tool changer, they offer high productivity. The availability of spindle rebuild and spare parts repair services ensures the long-term reliability and durability of these machines.
For example, heavy-duty boring machines feature a movable column design ideal for highly productive large part machining. Their range covers dedicated solutions for wind turbine and hydroelectric components, with maximum productivity for the aerospace industry’s oversized parts. MTE offers a variety of multi-axis universal machining centers with rotary tables and infinitely positioning heads for precision machining complex components in a single setup.
5-Axis Traveling Column
Built for high rigidity and precision, our 5-axis traveling column machine can handle large-volume machining tasks efficiently. The high-speed spindle with variable speed control makes this machine more versatile. This machine comes with advanced features such as end-mill compatibility, OEM retrofit capability and remote diagnostics.
Rotary Tables
With high precision, efficiency and flexibility, our rotary tables add value to the CNC machining process. Built for longevity, these tables transform a 3-axis machining center into a 5-axis machine for complex machining tasks.
They feature superior indexing capabilities with advanced CNC control, which boosts productivity and reduces machining time.

Press Brakes
Press brakes, built for bending sheet and plate material, are indispensable for metal fabricating tasks. With large work enclosures, our press brakes can handle large workpieces and deliver precise results.
Press brakes utilize tremendous force to transform flat sheet metal into precise angles and forms. As the punch presses down, the sheet metal is squeezed between it and the shaped die below causing the material to plastically bend along the predetermined form. With capacities up to thousands of tons, today’s large CNC press brakes employ hydraulic, servo electric or eccentric drive systems to supply the needed pressures for bending thick plates with tight tolerances.
