Fast feed rates up to 17,000 mm per minute
Meanwhile, feed speeds of up to 17,000 mm/minute can be achieved (depending on the contour shape of the workpiece). Thus the machine is definitely in the speed range of much more expensive servo-driven CNC mills! This machine type can be used efficiently in trade and industry for milling and engraving work. The mill is equipped with closed energy chains on each axis.
CNC mill with HF spindle and tool changing system
Servo motors T-Rex servo with tool changer station
Our CNC mills T-Rex are available in different sizes and with individual configuration. You, therefore, have the choice between machine systems with air-cooled or water-cooled high-frequency spindles, with or without a tool changing system, as required. We offer tool changing stations with up to 12 tool places, whereby the number of tools varies according to the size of the CNC router.
If you choose a CNC machine with tool changer, please note that the machine length increases by 300 mm in X-direction. That allows you to use the whole working area without any restrictions due to the mounted tool changing system.
If a decision is only made subsequently for a tool changing system, this is possible, but with a loss of the travel range by 300 mm.
Selectable high-frequency spindles from HSD or other high-quality brand manufacturers
Depending on the application, different HF spindles can be optionally selected. You can choose between 1.5 kW ER20, 3.5 kW ER25, a high-frequency spindle with 6.0 KWor optionally also an HSD spindle with 7.5 kW and a SK30/ISO30 tool holder.
Including manual central lubrication / automatic optional
The manual central lubrication makes in the work process much more comfortable and is also equipped as a standard on T-Rex machines. The use of the manual central lubrication system is effortless and convenient via a lever on the bridge of the CNC router.
As an option, you can choose the automatic central lubrication for an extra charge, thus not only saving on personnel expenses but also having a more efficient use of lubricants. Here you can program in intervals so that you do not have to check this always personally.
Zone vacuum table as standard equipment
CNC router zone vacuum table t-slot rail
You can also arrange the work surface can according to your wishes in terms of application and conditions. Either you work comfortably on the zone vacuum table with T-slot rails, with which the machine is equipped ex works, or you decide on the option with T-slot clamping possibility.
Here you decide for yourself how large the area you want to be to use it with T-slot plates. Of course, it is also possible to equip half of the working area with T-slot plates and leave the other half as it is. Depending on the planned application, the appropriate clamping method should be used.
As an optional accessory, we recommend the purchase of an oil-free vacuum pump or a side-channel compressor to make optimum use of the zone vacuum table. The individual zones of the vacuum table can be switchedon and off independently of each other using levers on the long side of the milling machine. Depending on the size of the CNC portal milling machine, the vacuum table is divided into different numbers of zones.
Optional: pneumatic dust extraction
The optionally selectable dust extraction system operates pneumatically and keeps the work surface free of dust and chips during the work process. The suction shoe can be lowered and raised again by using the toggle switch on the control panel. An all-round brush strip surrounds the suction shoe and can therefore adapt to any shape of the workpiece.

CNC mill – Design and functions
On closer examination of the CNC sector and related milling machines, we find the CNC mill is very popular. This fact encouraged us to answer some questions regarding portal milling machines:
What is a CNC mill?
What is this machine type used for?
Which software is suitable for working with a milling machine?
Which points are important when buying a CNC controlled mill?
Construction of a CNC mill
A CNC mill describes as the name indicates, a particular building type of a milling machine. Here, the X-axis is arranged horizontal, the Y-axis vertical, and the Z-axis perpendicular on the two other axes, which together results in a so-called portal. Some portal milling machines have multiple milling heads on the Z-axis, in addition to the milling head on the Y-bridge, to allow simultaneous processing of all sides in one step.
The workpiece to be machined is either mounted on a movable clamping table which moves within the portal in accordance with the desired material to be removed, or on a stationary clamping table which is travelled by the sled of the milling machine.
Which software is suitable for working with a CNC controlled mill?
A CNC mill operates like all milling machines with a so-called control software. Things which were manually done in the past with drawing paper and pencil, happens today, with much less effort, using a PC. Thanks to modern CAD (Computer-aided design) / CAM (Computer-aided manufacturing) control software, it is possible to send data sets, usually called DIN ISO G-codes, of almost any shape, whether 2D or 3D, to the machine. The machine then works row by row, until the workpiece has been processed as desired. Ready is your customized workpiece. Because also here applies:
The better all components are matched to one another, the more efficient and accurate a CNC mill will work!
It is recommended to contact a milling machine manufacturer or vendor for the purchase of a portal milling machine, offering for example free support even after purchase. This ensures that any initial difficulties, during incorporation into a control software are technically supported by experienced staff, in order to avoid additional, high costs. This makes the start much easier and cheaper!
Which points are essential when buying a CNC mill?
You should ask yourself the following questions before buying a CNC mill:
What type of material do I want to process and how hard is it regarding the engine power of the milling motor? Hard or soft? Heat sensitive?
What are the maximum sizes of my workpieces concerning the size of my desired milling machine?
Which quantities do I want to manufacture in one operation?
How exactly do the features of my chosen portal milling machine match the needs of my workpiece to be processed?
Do I feel well-advised?
Do I get expert support even after purchasing, possibly even free?
The more precisely you can define the requirements of the desired machine before buying, the more accurate a competent seller can offer the right machine, and then the more precise the milling results will be achieved. In a professional, experienced company, you will always have a trained technician and/or seller.
