CNC Milling Machine
We offer CNC milling machines from Röders and Trimill — from compact 5-axis HSC machines for mold manufacturing to large gantry machines with working areas exceeding four meters. Whether you’re machining hardened mold tools with micrometer precision or large aluminum structures, we have a milling machine that meets your requirements.
Our milling machines
What is a CNC milling machine?
A CNC milling machine is a computer-controlled machine tool that removes material using a rotating cutting tool—a milling cutter. Unlike a CNC lathe, where the workpiece rotates, the part remains stationary while the milling cutter moves along multiple axes simultaneously. The CNC (Computer Numerical Control) system enables the machine to follow a preprogrammed path with repeatable accuracy, allowing for complex geometries, tight tolerances, and a high-quality surface finish. CNC milling machines are used in mold making, toolmaking, the aerospace industry, medical technology, and general contract manufacturing.
3-axis, 4-axis, and 5-axis CNC milling
The number of axes determines how many movements the machine can perform simultaneously—and thus how complex the parts it can handle in a single setup.
3-axis milling
Three linear axes (X, Y, Z) allow for machining from one direction at a time, typically from above. This is sufficient for flat surfaces, pockets, and simple 3D contours. 3-axis milling is the cost-effective choice for simpler parts and smaller production runs. Trimill’s VC series—with working ranges from 1,800 to 4,500 mm on the X-axis and feed rates up to 40,000 mm/min — is designed for large-scale 3-axis machining of aluminum, composite, and steel.
4-axis milling
A fourth axis (rotation around the X-axis) allows the workpiece to be indexed or rotated continuously during machining. This reduces the number of clamping operations for parts that need to be machined from multiple sides—such as camshafts, cylindrical fixtures, and tools with profiles around their entire circumference.
5-axis milling
Five simultaneously controlled axes (three linear + two rotary) allow the tool to access the workpiece from virtually any angle. Complex surfaces such as turbine blades, implants, and molds can be finished in a single setup, without repositioning. Röders’ RXP and RPT series are 5-axis HSC machines with linear motors and nanometer-precise guideway geometry—designed for mold making and finishing applications where surface finish and accuracy are critical. Trimill’s VF and VFC series offer 5-axis capability in larger formats, with working areas up to 4,500 × 4,500 × 1,500 mm.
Our Brands in CNC Milling
Röders — A German manufacturer with over 3,000 machines installed in 50 countries, specializing in 5-axis HSC (High Speed Cutting) milling machines with linear motors. Röder’s proprietary control system, temperature compensation, and geometry compensation provide accuracy down to the micrometer level. The machines (RXP and RPT series) are used in mold making, electrode production, and high-precision manufacturing.
Trimill — Czech manufacturer of large gantry machines and 5-axis machining centers. The VC Series (3-axis), VF Series (5-axis), and VFC Series (compact 5-axis with fixed table) cover working ranges from 1,800 mm up to 5,000 mm in the X-axis. Trimill machines are designed for heavy-duty machining of large-format steel, aluminum, and composites.
Frequently Asked Questions About CNC Milling Machines
What is the difference between 3-axis and 5-axis milling?
A 3-axis milling machine machines from one direction at a time (X, Y, Z) and requires repositioning to access multiple sides of the workpiece. A 5-axis machine has two additional rotating axes that allow the tool to access the workpiece from any angle without repositioning. The advantages of 5-axis machining include fewer setups, shorter cycle times, better surface finish, and the ability to machine complex geometries that would otherwise require multiple machines.
What materials can a CNC milling machine machine?
CNC milling machines can machine most engineering materials: tool steel, stainless steel, aluminum, titanium, brass, copper, hardened steel (up to 65 HRC with the right machine and tools), composite materials such as carbon fiber and fiberglass, as well as various plastics. Röders’ HSC machines are specifically designed for hardened materials and shaped steel, while Trimill’s gantry machines handle large workpieces made of aluminum and steel.
Do I need a 5-axis milling machine?
It depends on your parts. If you regularly machine complex 3D surfaces, molds, electrodes, or parts with undercuts that require multiple setups on a 3-axis machine—then a 5-axis machine pays off through shorter cycle times and greater precision. For simpler parts with flat surfaces and pockets, a 3-axis machine is often sufficient. Contact us We'll help you determine what's right for your production.
