Buying advice: How to find the right milling machine
The most important facts in brief
CNC milling machines are among the most precise machine tools in modern manufacturing. They work with multiple axes (X, Y, Z), are controlled via CAD data and process materials such as metal, wood or plastic efficiently.
<pUsed milling machines are an attractive alternative, especially on the used market, as they are significantly cheaper than new machines. However, these points should be checked before buying:
<p- Precision & efficiency: high repeat accuracy and reliable results .
- Cost savings: used models are significantly cheaper than new machines.
- Machine condition: Maintenance history and technical status are crucial.
Checklist: What you should look out for when buying a CNC router
Before you invest, you should check various points in detail. A clear checklist will help you make the right choice:
- Check condition: Is there any visible wear or technical defects?
- Ensure compatibility: Does the machine match your software and production environment?
- Arrange a test run: This is the only way to realistically assess precision and function.
- Consider additional costs: Don't forget transportation, installation and possible retrofits.
- Choose a reputable provider: Look out for guarantees and a reliable dealer.
This will help you avoid bad purchases and ensure that you get a machine that meets your requirements in the long term.
CNC milling machine explained simply: definition & meaning
A CNC milling machine is a computer-controlled machine tool that processes workpieces made of materials such as metal, plastic or wood with millimetre precision. The abbreviation CNC stands for Computerized Numerical Control - a control technology that automates processes and thus enables consistently high quality
.The use of CNC technology allows errors to be reduced, tolerances to be reliably maintained and product standards to be permanently secured. As a result, CNC machines have become indispensable in industries such as metalworking, mold making and woodworking.
<pHow does a CNC machine work? Structure & mode of operation
Main components of a CNC milling machine
- Spindle: holds the tool and ensures the right speed
- Milling table: fixes the workpiece during processing.
- Axes: move the tool and workpiece in the X, Y and Z directions.
Process steps of CNC machining
- Programming the machine: via CAM software.
- Material processing: using rotating milling tools.
- Automatic control: to ensure exact results.
The result is workpieces with consistently high accuracy - even in series production.
Where are CNC milling machines used? Typical applications
CNC milling machines are versatile and can be used in almost all areas of industry:
- Metal processing: Production of machine components, tools and prototypes .
- Woodworking: Production of furniture parts and decorative elements.
- Automotive industry: Production of engine components, body parts and tools.
- Medical technology: Development of implants, surgical instruments and devices.
- Aerospace: Machining of complex components with tight tolerances.
Types of CNC milling: 3-axis, 4-axis, 5-axis & more
3-axis milling machines
In 3-axis milling machines, the tool moves along the X, Y and Z axes. This design is particularly suitable for standard machining operations such as drilling holes, grooves or simple contours. It is often used with vertical milling machines.</p
4-axis milling machines
4-axis milling machines add an additional rotational axis, usually the A or B axis, to the classic 3-axis machining process. This means that workpieces can also be machined laterally - ideal for more complex geometries or cylindrical parts. They are available in both vertical and horizontal versions.
5-axis milling machines
5-axis milling machines offer maximum flexibility: In addition to the movements in X, Y and Z, two rotation axes can be controlled. This means that even complicated free-form surfaces and components with tight tolerances are possible. These machines are available as vertical machining centers and as horizontal milling machines, depending on the area of application.</p
Vertical milling machines
Vertical milling machines have a vertical spindle. They are particularly suitable for processing flat surfaces, pockets or contours. They are typically used as 3- or 4-axis models, and also as state-of-the-art 5-axis machining centers if required.</p
Horizontal milling machines
The spindle of horizontal milling machines is arranged horizontally. This means that even large and heavy workpieces can be processed efficiently. This design is often used as a 4- or 5-axis machine and is particularly suitable for deep cavities or complex components in series production.</p
Used milling machines - costs at a glance
The prices for used milling machines vary greatly. Several factors are decisive:
- Model: Standard machines are cheaper than specialized systems .
- Size: The larger the processing area, the higher the acquisition costs.
- Functionality: Extra features such as 5-axis machining increase the price.
- Manufacturers: Brands such as DMG, Doosan or Hermle are more expensive, but often offer a longer service life.
Entry-level models are available from around €500. Specialized high-end machines, on the other hand, can cost several hundred thousand euros.</p
Why a used CNC milling machine is worthwhile
Buying a used milling machine offers several advantages:</p
- Cost savings: significantly cheaper than new machines and lower depreciation
- Fast availability: immediately ready for use, no long delivery times.
- Tested quality: frequently serviced or retrofitted, ready for immediate use.
- Sustainability: Reuse reduces resource consumption and CO₂ emissions.
This makes a used CNC milling machine an attractive choice not only economically but also ecologically.
Tips for buying a used machine tool
If you want to buy a used milling machine, you should prepare well:
- Define your requirements in advance (materials, sizes, functions) .
- Only buy from reputable specialist retailers who offer advice and a guarantee
- Check the maintenance status, possible retrofits and existing documentation.</li
This will ensure that the machine works reliably in the long term.</p
