KEKEISEN PFW-T 4000/12 portal milling machine in a heavy, rigid design for machining large and heavy workpieces.
Travel paths of 4,000 x 2,700 x 1,200 mm and a large worktable of approximately 4,000 x 1,800 mm with a table load capacity of 10,000 kg enable the machining of large-volume components.
The machine is equipped with a universal milling head with 2 swivel axes and 5 - 1 degree steps NC controlled - adjustable positions (manually or optionally NC-controlled). Hirth gearing ensures precise angle settings.
Powerful main spindle drive with approximately 30 kW. Speed range 20 – 7,000 rpm, maximum torque of approximately 1050 Nm.
Additional equipment includes a 60-tool changer (KWE60), chip conveyor, KNOLL filtration system, Hydac cooling units, and central lubrication.
Feed rate up to 4 m/min, rapid traverse up to 18 m/min, and feed forces of approximately 30,000 N per axis underscore the robust design of the machine.

Transportation costs are not included in the used milling machine price; terms of delivery and payment are stated under "Additional information" in each listing. You should also budget for installation and commissioning at the new site. In most cases, the buyer is responsible for organizing the transport; upon request, ReMach can check whether transport can be arranged or supported. ReMach also helps with dismantling, loading and export paperwork.
Choose the control your operators already know and that is compatible with your existing programs and CAM post-processors. On European machines the most common controls are Heidenhain (TNC, conversational Klartext programming), Siemens SINUMERIK and FANUC. The control version determines the available functions, such as 5-axis cycles, and the availability of spare parts.
The five axes are three linear axes, X, Y and Z, plus two rotary axes, usually two of A, B or C depending on the machine design. In 3+2 machining the rotary axes tilt the part to the required angle before the linear axes cut; in simultaneous 5-axis machining all five move together for complex freeform surfaces. A swivel head suits large, heavy parts, while a swivel-rotary table limits part size and weight to the table.
Choose by the size, weight and shape of your parts. A vertical machining centre suits small and medium parts in series; a portal milling machine handles large, heavy parts such as moulds and machine beds; a bed-type milling machine, with its table on a fixed bed, offers the rigidity for long parts and heavy cutting. A 5-axis machine is for complex parts machined on several sides with few set-ups, while a horizontal boring mill suits large prismatic parts with precise bores on several faces.
A machining centre is a CNC milling machine with a tool magazine and an automatic tool changer. This lets it perform milling, drilling, tapping and boring in one set-up without manual tool changes. The number of magazine positions in the listing shows how many tools a part can use.

1. Portal Milling Machines: Design, Uses & Capabilities
A portal milling machine is a cornerstone of industrial manufacturing, designed for the precise machining of large workpieces across a wide range of materials. Its defining feature is a crossbar of adjustable height mounted between two vertical supports – a rigid portal structure that determines the maximum workpiece width and ensures exceptional stability throughout the machining process.
Height-adjustable crossbar limits maximum workpiece dimensions, accommodating a variety of large components
Effective face milling of large surfaces in a single setup
Widely used in mechanical engineering and heavy industry
The supports can be either fixed or movable, and most designs incorporate an adjustable clamping table for greater flexibility. Two additional milling heads mounted on the supports allow all sides of a workpiece to be machined in a single clamping operation, significantly reducing setup times and improving throughput.
The inherently rigid construction of portal milling machines enables very high dimensional accuracy – down to approximately 0.005 mm – with minimal vibration during operation. This results in excellent surface finishes and consistent quality across large workpieces. The robust design also allows for high cutting capacities, making portal milling machines the preferred choice for demanding applications in machine construction and heavy industry.

2. Portal Milling Machines: History and Development
Machine construction in Germany has deep roots, beginning with the founding of the first machine factory in Chemnitz in 1848, where early machine tools were designed and produced. One of the machine types to emerge from this tradition is the portal milling machine – a design that has continually evolved while retaining its core working principles.
The introduction of computer technology marked a turning point, bringing NC-controlled and later CNC-controlled portal milling machines to market. Today, the range of available machines spans compact models through to large-format systems capable of accommodating multi-ton workpieces on their machining tables.
3. Portal Milling Machines: Applications & Industry Uses
Portal milling machines are widely used in mechanical engineering and heavy industry. A typical application is the machining of cast steel and cast iron housings for transmissions, where precise face surfaces are essential to allow the housing to be flanged directly onto a motor. These machines are also well suited to heavy-duty machining of tool steel and titanium.
4. Portal Milling Machine Manufacturers & Brands
Several manufacturers have specialised in portal milling machines. Among the most reputable brands are FOREST-LINE, ZIMMERMANN, WALDRICH-COBURG, SNK, SCHIESS ASCHERSLEBEN, MAZAK, BOEHRINGER, MIKROMAT, TOS, and KOLB – each with a strong track record in producing high-quality, precision gantry milling equipment.
Used portal milling machines in good condition are widely available on the second-hand market, making it possible to acquire reliable, high-performance machinery at a fraction of the cost of new equipment.
