What are milled parts?

Milled parts are mechanically machined workpieces that are produced by milling. Analogously, one speaks of welded parts in welding, laser parts in laser cutting or turned parts in turning.

Milled parts are mechanically machined workpieces that are produced by milling. Analogously, one speaks of welded parts in welding, laser parts in laser cutting or turned parts in turning.
The milled part is milled by a milling machine according to a geometrically precisely defined production drawing. Milled parts are available in a wide variety of materials. These include metals (such as aluminium), wood or plastic. The milled CNC parts are important functional parts in machine and plant construction. Other typical areas of application for us as a supplier are CNC milled parts for the aerospace industry or, for example, CNC milled parts for medical technology. Characteristic for CNC milled parts are the cleanly defined shapes as well as smooth surfaces, which are manufactured with the help of modern CNC milling centres or combined turning and milling machines.

CNC-Milling and machining by SPALECK

Precision milled parts accurate to the millimetre

We deliver precision. Since 1869.

In order to meet your requirements, our state-of-the-art machinery allows us to maintain tolerances of less than 0.02 mm. As a subcontractor for machining , we produce these very precisely or accurately manufactured production parts using the milling manufacturing process. You can find more information about precision parts here.

Where are milled parts used?

Areas of application for milled parts

illed parts are typically components that are used in mechanical engineering, among other things. Because they belong to the precision parts , they have a high quality, accuracy and mechanical resilience. Areas of application are, for example, general mechanical engineering, railway technology or the medical sector. Thanks to state-of-the-art milling and machining equipment, we are able to offer you leading quality at an absolutely competitive price. Test us now andsend us your enquiry for milled parts!

Which milling processes are available?

Our milling processes according to DIN 8589

Face milling is used to make flat surfaces. It is the most commonly used milling process. Sub-processes of face milling are essentially end milling, roller milling and disc milling. Examples of products for face milling are flange sealing surfaces, gearbox and motor housings and all types of face surfaces.

With circular milling, we produce circular-cylindrical external and internal surfaces. The circular feed motion is generated either by the tool or by a workpiece, depending on the type of CNC machine.

In screw milling, screw-like shapes are produced. Examples of production are threads, cylindrical worms and spindles.

Gear hobbing is used for the production of rolling surfaces. This mainly includes gear teeth on gear wheels and gear racks. As a rule, hobs are used as tools. Their profile corresponds to the teeth which are to be produced. For an optimal production quality, the cutting machinist coordinates the rotation of the cutter, the feed and the rotation of the gear. Finally, the gears are mostly machined by gear grinding.

Profile milling cutters are used for profile milling. These contain the workpiece to be produced as a quasi-negative form. Examples are slot grooves, T-slots or dovetail grooves. Circular grooves can be produced by workpieces rotating around their own axis. The feed motion determines whether round, straight or other shapes are produced.

The tools used in form milling do not carry the form they are going to produce. Individual three-dimensional shapes can be created by programming the feed movement.

How are milled parts manufactured?

CNC machining of milled parts

We manufacture your CNC milled parts on high-performance and state-of-the-art CNC machining centres to guarantee you optimum quality. CNC stands for “Computerized Numerical Control”.Your requirements for the finished milled part are the basis of our contract manufacturing and contract machining of the blanks.

During milling in production, the excess material of the workpiece is removed by rotating the milling tools. For this purpose, the blank or the prefabricated component is clamped in the milling machine. The milling tools then remove the blank at high speed in precisely defined milling paths. Depending on the material and shape of the milled part, a distinction is made between up-cut and climb milling processes with regard to the running direction.

What is a milling machine?

Briefly explained!

Milling machines are fully or partially automated machine tools that mill workpieces with fast rotating cutting tools in a mechanical machining process and convert them into the desired milled parts. Milling machines are characterised by multiple moving axes (three- or five-axis systems), each of them can be individually controlled and equipped with tools or workpiece carriers. Machine sensors and our highly trained cutting mechanics monitor the production process to ensure that the component is manufactured to your specifications and in high quality. Milling machines can be divided into the following machine types:

  • Console milling machines
  • Bed milling machines
  • Special milling machines
  • manual or CNC-operated
  • Machining centres
  • Travelling column milling machines

In general, milling machines are divided into vertical and horizontal milling machines according to the position of their milling spindles.
