Milling spindles are key components in milling machines used in the metalworking industry. They play a crucial role in milling, a machining process where material is removed from a workpiece to achieve the desired shape or surface.

Here are some key aspects of milling spindles:

  1. Function:

    • Milling spindles are motorized components that generate a rotating motion to drive milling tools.
    • They transfer the necessary energy to the milling tool, allowing it to cut, shape, or process the workpiece.
  2. Applications:

    • Milling spindles are used in various applications, from simple milling machines to high-precision CNC (Computer Numerical Control) machines.
    • Typical applications include the manufacturing of precision components in aerospace, automotive, medical technology, and other industries.
  3. Operating Principles:

    • Milling spindles operate based on the rotation of the motor integrated into the spindle.
    • The spindle can provide different speeds and torques to meet the requirements of various milling tasks.
  4. Speed Control:

    • Precise speed control is crucial to ensure the quality and accuracy of machining.
    • Modern milling spindles often feature speed control systems to adjust the speed according to specific requirements.
  5. Tool Holder:

    • Milling spindles have a tool holder that allows secure attachment of various milling tools.
    • Common tool holders include SK (Steep Taper), HSK (Hollow and Shank Taper), or BT (Machine Taper).
  6. Cooling:

    • Heat is generated during the milling process, so many milling spindles are equipped with a cooling system to prevent overheating and extend the lifespan.
  7. Accuracy and Rigidity:

    • High-quality milling spindles exhibit high rigidity and precision to achieve accurate machining results.
    • These characteristics are particularly important when manufacturing complex parts with tight tolerances.

In summary, milling spindles are crucial components in the metalworking industry, used for the precise machining of workpieces in various sectors. Their performance and precision directly influence the quality of the manufactured parts.

About Rocketronics

Rocketronics was founded in 1999 as a family business by Louis Schreyer. As an engineer for microelectronics, I design hardware and also develop the software for it. We manufacture our products in-house on our own machines, and this for over 20 years now - made in Germany. In addition to the development and production, the testing of the products is also carried out here. We also manufacture the prototype construction and the test fixtures ourselves. We use lathes and milling machines for this, but we also use our 3D printers a lot. The CNC milling machines we build ourselves produce many small parts, e.g. for the housings of our controllers.

In addition to manufacturing controllers, we also trade in the necessary components. As a dealer we have a large stock of components for machine building and automation, which we offer in this store. Our suppliers are the original manufacturers, with us you buy tested branded goods. 

We also consult you when it comes to choosing the right components. We have a lot of experience in building and operating CNC milling machines and lathes. We can help you if you have questions, be it about the control system, the choice of drives or in general about the construction of CNC milling machines and the conversion of lathes. 

Our online store shows you all items available for immediate delivery, and allows you to shop securely with many payment methods and fast shipping. Data traffic is of course encrypted, payment is processed and secured by reputable service providers, and we offer a 30-day return policy
