What is a Kessler spindle? | Broch'Express

Introduction

Modern industries face many challenges to remain competitive in the market, and their machines are one of the key elements of success. Spindles, as essential components in these industrial machines, are often subject to significant stresses. In this context, the Kessler brand offers high-performance spindles to meet the specific requirements of different industries. So, what is a Kessler spindle and how does it stand out from other models available on the market? This article provides the answers.

Understanding Kessler spindles

Spindles are mechanical devices used in many industrial applications, particularly in CNC (Computer Numerical Control) machine tools. They enable the rotation of cutting or forming tools at high speeds and forces, thus ensuring great precision and good performance during the production process. Among spindle manufacturers, the German company Kessler is recognised for its high-end products that offer exceptional durability and reliability. With several decades of experience and expertise, Kessler offers an extensive range of spindles adaptable to different machine configurations and specific customer needs.

Main characteristics of Kessler spindles

Here are some of the main attributes that make Kessler spindles so effective:

Quality: Kessler products are manufactured from high-quality materials, giving them outstanding longevity and durability. Each spindle undergoes rigorous checks during the manufacturing process to ensure optimal performance.
Flexibility: Kessler spindles are available in various configurations to meet specific customer needs and adapt to different industrial machines. These include models with air or liquid cooling, with different tooling types such as HSK (Hollow Shaft Taper) or ISO (International Organisation for Standardization) taper connections.
Power: Thanks to design and manufacturing quality, Kessler spindles deliver high power while maintaining low vibration and reduced noise levels, which helps optimise the productivity and performance of machine tools.
Maintenance: One of the main concerns encountered on industrial machines involves the servicing and maintenance of components. The Kessler brand has carefully developed its spindles to reduce routine maintenance operations and thus ensure better availability and longevity of the equipment.

The different types of Kessler spindles

Depending on the applications, Kessler develops and markets several types of spindles:

Built-in motor spindles

These spindles are specially designed for CNC machine tools and other applications requiring high performance. The motor is directly incorporated into the spindle, enabling better power transmission and reducing energy losses.

Vertical and horizontal spindles

Vertical: Kessler vertical spindles are used for machining centers equipped with a fixed or mobile table where the tool moves only in rotation around the Z axis.
Horizontal: These spindle models are suited for machines with a horizontal X axis. They are commonly used for machining operations on a wide variety of materials, including wood, plastic and non-ferrous metals.

Milling spindles

This category encompasses spindles designed for milling operations such as cutting, roughing or surface finishing. They are used on machines dedicated to drilling, tapping and contouring.

Grinding spindles

Kessler grinding spindles are designed to achieve very high speeds during surface preparation operations to obtain great geometric precision and excellent surface quality. They are often used in high-speed machining centers or specialised machines for part grinding.

Custom spindles

Finally, Kessler is also capable of designing and producing custom spindles to meet specific customer requirements, whether in terms of size, power, cooling or other particular specifications.

Conclusion

Ultimately, equipping with a Kessler spindle guarantees increased productivity, optimal reliability and extended service life for all mechanical equipment related to the production process. These superior quality products continue to be associated with a high level of performance and customer satisfaction.
