General information about CNC milling machines
1. What is a CNC milling machine?
The peculiarity of a CNC milling machine over a conventional milling cutter can be derived from the name suffix CNC. This is an abbreviation for "computerized numerical control", which means "computer-aided numerical control" - an electronic method for controlling machine tools.
2. What advantages does a CNC milling machine have?
Compared to conventional milling machines, the key advantage of a CNC machine is clearly its computerized control. This makes it possible to make high-precision and delicate shapes and profiles from numerous starting materials such as wood, metal or stone. Thanks to modern control technology, all work steps are carried out automatically and error-free with special software, and at the same time high volumes are achieved.
3. In which areas are CNC milling used?
Due to their versatility, CNC machines are used in a wide variety of industries and applications and are an indispensable part of industrial production in particular. Moldmaking and model making also benefit from precise CNC production since the machines are ideal for milling different materials such as aluminum, wood, brass, bronze, plastics or steel.
4. What is the difference between CNC milling machines?
Depending on the application, CNC milling machines differ, for example, in their size and the type of construction. Thus, the "travel range" of the machine depends on the size of the system and can be between 300 x 200 mm up to 3000 x 6000 mm. The number of possible axes also depends on the structure of the machine. Depending on which material is to be processed, different main spindle drives with a power range from 300 W up to 12 KW can be used. The main spindle drives also differ in the tool change modes. There are main spindle drives where the tool must be changed manually and those that are designed for automatic tool change. The tool changers are also available in different sizes and designs. The span ranges from 3-fold to 50-fold tool changers. When selecting the correct tool changer, the interface of the main spindle drive must be observed. Another significant difference is the drive type of the axles. The simplest type of drive is a linear drive that is driven by a stepper motor. The next higher technology level is a linear drive driven by a servomotor. The high-end solution consists of linear axes with linear motors that have digital measuring systems (glass scales). If you are unsure which CNC mill is right for your application, please do not hesitate to contact us. Together we will find the optimal solution for you.
5. What distinguishes a good CNC milling machine?
Since CNC milling is so versatile, a good one is characterized by its attractive price-performance ratio. Finally, CNC systems can be produced according to their requirements in completely different stages of development. It is therefore not always necessary to use high-precision systems that mill in the tolerance range of 8μm. Nevertheless, there are some features that every good CNC mill should bring. These include process reliability as well as high geometric accuracy and dynamics. Intuitive operation, a high process speed as well as the modifiability and open interfaces round off the requirement profile of a good CNC milling machine.
6. What are portal milling machines?
A portal milling machine is a mill, whose milling head is attached to a crossbeam, which is guided between two uprights. Due to the construction, this CNC mill acts like a portal, from which the name results. The material to be processed is set up on a fixed clamping table or in a clamping field with fixed uprights on a movable clamping table. In the industrial sector, a portal milling machine is suitable for the effective processing of large areas and is often used for face milling of large panels. A corresponding portal milling machine from imes-icore is the large format MMF CNC milling machine.
7. Can you build a CNC milling machine yourself?
Since our CNC milling machines have a modular structure and are therefore adaptable to application, they can be assembled by a technically skilled person. As long as you do not want to use a CNC mill as a hobby, we strongly advise against it. The quality and effectiveness of a self-made solution does not come close to an industrially manufactured system, for reasons of quality assurance.
8. What do I need to know about the CNC control and drive technology?
8.1. What's the difference between stepper and servo motor technology?
The servo drive is a regulated (closed) system and has a rotary encoder (encoder) for the distance measurement, or detection of the current position. Thus, a constant comparison between the target and actual position takes place, whereby the servo drive moves exactly in accordance with the predetermined path profile. In addition, the servo motor has a high torque over the entire speed range. In contrast, the stepper motor drive is a controlled (open) system in which the positioning is done by presetting the number of control pulses (steps). The torque decreases over the speed range. If exceeded, there is a risk of "step loss".
Advantages of servomotors over stepper motors
- Capture the current position
- Constant target / actual comparison
- Homogeneous railway operation or homogeneous track behavior (look ahead)
- Higher dynamics result in much higher feeds and speeds
8.2. What is the difference between DC and AC servomotor technology?
DC servomotors are brushed (brushed) motors. AC servomotors are brushless and thus maintenance-free milling motors. Furthermore, the AC servos have very quiet running characteristics, much greater dynamics and very good control behavior.
8.3. What is a linear motor drive for CNC milling machines and what are its advantages?
A linear motor is an electric motor in the "extended state". While the feed forces are normally generated by a rotating electric motor (DC / AC servo motor) and converted into a translatory movement - the movement thus "indirectly" brought about - allow linear motors directly to represent a translational movement. For this reason, they are called "direct drives".
Advantages of the linear motor in CNC milling
- Very high dynamics and high acceleration
- No mechanical friction
- No backlash
- No axis or positioning problem
- No mechanical transmission links
9. What does HSC milling (HSC milling technology) mean?
HSC milling stands for high-speed cutting - high-speed cutting. Requirements for HSC milling are:
- Highly dynamic CNC mills with very fast control technology (control cycle time <1ms), in order to be able to keep the high feed rates and the true tracking even with complex geometry shapes
- a stable mechanical design of the CNC milling machine with good damping properties
- High-frequency spindles, which provide the required speeds especially for the very common small tools
- highest concentricity (about 3 to 4 μm)
- CAD / CAM milling systems with HSC milling strategies
Our CNC milling machines in the product group HSC-Premium fulfill all these criteria.
10. Main spindle drives (milling spindles) for CNC milling machines
10.1. What is the difference between a pneumatic direct changer and an automatic tool changer with steep taper mountings?
In the pneumatic direct change system, the milling tools are inserted directly into the tool station of the CNC mill. The position (position) of the tool is limited by special fixing rings, which are pulled over the milling tools.
11. Which spindle power is suitable for which application?
The required spindle power is matched to the respective milling application. Engraving, for example, uses motors with lower power but very high speeds. Depending on which cutters are to be used, you need a spindle with the appropriate interface, such as HSK E25, HSK E32, SK20, SK30, SK40, etc. If you have any questions about the spindle power for your application, please contact us directly.
12. What are the requirements for setting up a CNC milling machine?
The CNC mill requires a suitable power connection in accordance with the main spindle drive and the equipment of the system. If required, both dry and oil-free compressed air as well as a connection for vacuum pump, exhaust system, etc. are required.

13. How long is the delivery time of a CNC milling machine?
The delivery time of a CNC mill depends on the respective machine system and the milling tools. For example, ICP milling machines have a delivery time of 4 to 6 weeks. For standard milling machines with servomotors, the delivery time is about 8 to 10 weeks, while the delivery time of special CNC mills that are "tailored" to the customer varies between 12 to 26 weeks. This variance arises due to the individual complexity of the system and the controller. A CNC mill for demonstration purposes is of course immediately available.
14. How much does a CNC mill cost?
The cost of a CNC milling machine depends on the system of your choice and the size of the accessories selected. For example, a small table-top machine is available from as little as 4,000 euros, while high-end systems with Heidenhain control have a correspondingly higher subscription price.
15. Does imes-icore GmbH also sell used CNC milling machines?
From time to time, customers may want to pay an old mill to purchase a new CNC mill. This makes it possible for us to have a used CNC mill available. We sell these on, if you want to buy a used CNC milling machine.
16. What configuration options are available for a CNC milling machine?
The possibilities of equipping a CNC mill are manifold. Main spindle drives, length measuring systems, tool changers, cooling systems, extraction systems and various other components can be freely selected by the customer. The large number of options in the selection of individual components allows a very high degree of customization and specialization.
17. What warranty do we give on our CNC milling machines?
Each customer receives a 12-month warranty on every CNC milling machine. On main spindle drives (rotating parts), we grant a six-month warranty as required by law. This can be extended on fair terms.
18. Which service intervals does a CNC milling machine have?
Depending on the capacity of the CNC system, we recommend different maintenance intervals. In single-shift operation we recommend at least one maintenance per year. In multi-shift operation, however, maintenance should be carried out every six months. The cleaning and cleaning, however, can be carried out by the customer himself. The same applies to minor maintenance work on the CNC mill.
19. What are the service hours of our technicians for CNC milling systems?
Our service is available from Monday to Thursday 08.00 - 16.30 and Friday 08.00 - 14.30.
20. Which conversion expansion options are available for CNC milling machines?
Our CNC mills can be retrofitted with optional CNC accessories. For example, a stronger main spindle drive and a tool changer can be installed. Or you can add a minimum quantity of cooling lubrication or an additional rotation axis to the CNC mill. There are almost countless CNC variants available.
