Definition and function of milling machines

A milling machine is a machine tool that is used to machine workpieces using the milling process. This machining production process enables the manufacture of complex workpieces such as engine blocks and gears, as well as precise drilling and reaming. Milling machines are characterized by three or more axes of movement, which are assigned to either the tool or workpiece carrier. A multi-bladed milling tool moves through the material and removes material in a targeted manner.

Simpler milling machines have a horizontally and vertically movable machine table and a horizontally movable milling head. Sophisticated, modern machines have additional rotation and swivel options for the tool or workpiece holder in order to offer a wide range of processing options.

CNC (Computerized Numerical Control) milling machines in particular automate all movements using storable programs. These machines can be controlled directly via CAD data and offer high accuracy and flexible production options.

Use and advantages of CNC milling machines

CNC milling machines are used wherever high productivity and precise production quality are required. Advanced motion control and powerful drive concepts such as high-speed spindles, linear motors and torque motors ensure constant production times, which optimizes production planning. This means that consistent results can always be achieved, even with large quantities, which is particularly advantageous in mechanical engineering and series production.

CNC milling machines are suitable for processing a wide range of workpieces and offer comprehensive processing options such as drilling, reaming and cutting.

What types of milling machines are there?

Milling machines can be divided into several types according to spindle position, control and design. Important types are:

• Horizontal and vertical milling machines
• Universal milling machines that combine versatile functions and are suitable for numerous machining operations
• High-speed milling centers (HSC), which enable fast and precise work and are particularly popular in series production
• CNC machiningcenters that offer a high degree of flexibility through automation and can process complex workpieces efficiently

A universal milling machine enables the processing of heavy or large workpieces, while a CNC machine can also process particularly demanding workpieces thanks to its flexibility.

Why buy a used milling machine?

Buying a used milling machine can be a cost-effective alternative to purchasing a new one. Used milling machines often offer the same functions as new machines, but at a fraction of the cost. This is a particularly sensible option for beginners or companies with a limited budget.

Why buy a used milling machine?

Buying a used milling machine can be a cost-effective alternative to purchasing a new one. Used milling machines often offer the same functions as new machines, but at a fraction of the cost. This is a particularly sensible option for beginners or companies with a limited budget.

What are the advantages of buying a used milling machine?

1. Lower acquisition costs: Used milling machines are often up to 50% cheaper than new models, which is an attractive solution, especially for companies that want to save on their budget.
2. Ready for immediate use: Well-maintained, used machines are often ready for immediate use, saving time and costs for installation and running-in.
3. Stable value: Used machines have already lost most of their value and offer a more stable performance.
4. Lower financing costs: Used machines usually incur lower interest rates and fees as the amount to be financed is lower.
5. Reduced depreciation costs: From a tax perspective, a used machine often offers faster depreciation, which can be advantageous for companies.

These economic advantages make the purchase of used milling machines an attractive proposition.

Technical and functional advantages of used milling machines

In addition to the cost benefits, used milling machines also offer technical advantages:

• Increased productivity through integration into existing production systems
• Variety of processing options for individual tasks through to mass production
• Longevity: Good care and regular maintenance make milling machines particularly durable
• Less tool wear: Constant operating conditions reduce wear on the milling tools

Sustainability benefits of used milling machines

Used machines also contribute to sustainability. By reusing them, resources are conserved and the production of new machines is reduced. This fits in well with today's requirements for more sustainable production and resource conservation.

Maintenance and care

A well-maintained milling machine remains reliable for a long time. Regular maintenance plays a key role in ensuring reliability and longevity. Particularly with used machines, targeted care is often the key to keeping them in optimum condition and minimizing production downtime.

What to do if the used milling machine you are looking for is not available?
