Exploring the Different Types of Tool Holders for Swiss Lathe Machines
Introduction:
Swiss lathe machines are widely used in the manufacturing industry due to their precision and versatility. These machines are capable of producing small, intricate parts with high accuracy. One of the key components that contributes to the performance of a Swiss lathe machine is the tool holder. In this article, we will explore the different types of tool holders used in Swiss lathe machines and their respective advantages and applications.
1. ER Collet Holders:
ER collet holders are commonly used in Swiss lathe machines for their ease of use and wide range of gripping capabilities. These holders use a spring mechanism to securely hold the tool in place. The ER collet system allows for quick tool changing, minimizing downtime during production. ER collet holders are available in various sizes, accommodating different tool diameters. They provide excellent concentricity, ensuring precise cuts. These tool holders are widely used in industries such as aerospace, automotive, and medical, where accuracy is crucial.
2. Weldon Holders:
Weldon holders, also known as end mill holders, are primarily used for milling operations in Swiss lathe machines. These holders have a threaded portion that allows the end mill to be securely clamped. Weldon holders provide excellent stability and rigidity, enabling high-speed machining without compromising precision. They are available in different sizes, accommodating various end mill diameters. Weldon holders are commonly used in applications such as milling slots, pockets, and contours in various materials including steel, aluminum, and composites.
3. Turning Tool Holders:
Turning tool holders are essential for the turning operations performed in Swiss lathe machines. These holders come in different shapes and sizes to accommodate different types of turning tools. They are commonly used for external and internal turning, facing, grooving, and threading operations. Turning tool holders are designed to provide optimum tool performance and minimize tool deflection, resulting in accurate and efficient machining. These holders are often made from carbide, which offers excellent wear resistance and heat dissipation.
4. Boring Bar Holders:
Boring bar holders are used for precision boring operations in Swiss lathe machines. These holders provide stability and accuracy during the machining process. Boring bar holders are available in various designs, such as straight shank and indexable boring bars, allowing for flexibility in different machining scenarios. They are commonly used in industries such as automotive, oil and gas, and general engineering, where precise internal bores are required.
5. Threaded Insert Holders:
Threaded insert holders, also known as insert tool holders or insert holders, are used for threading operations in Swiss lathe machines. These holders allow for quick and efficient tool changes, as the threading insert can be easily replaced. Threaded insert holders come in different designs, such as external and internal threading holders. They are commonly used in industries where threading is a primary operation, such as automotive, aerospace, and plumbing.
Conclusion:
In conclusion, the tool holders used in Swiss lathe machines play a crucial role in achieving precise and efficient machining operations. The different types of tool holders discussed in this article, including ER collet holders, Weldon holders, turning tool holders, boring bar holders, and threaded insert holders, offer unique advantages and cater to various machining needs. Understanding the characteristics and applications of each tool holder type is essential for maximizing the performance of Swiss lathe machines and ensuring quality manufacturing output.

I. Functional role
Slideways are the “track” between the guide rail and the moving parts. They convert the rotary (or linear) thrust of the servo motor into precise linear motion of the machine table, spindle box or turret, while withstanding cutting reaction forces, shocks and vibrations. Once the slideway fails, the positioning accuracy and surface quality of the whole machine will drop directly.
II. Common structure family
Linear ball slideway
Steel balls are in point contact with the raceway, low friction and fast response, suitable for high-speed and light-load Swiss-type lathes or vertical machining centers.
Linear roller slideway
Cylindrical rollers are in line contact with the raceway, high rigidity and large load capacity, the first choice for heavy-cutting equipment such as turn-mill centers and gantry five-face machines.
Dovetail slideway
Triangular interlocking surface, extremely strong lateral force resistance, often used in grinders or ultra-precision machining units that require micro-feed.
Hydrostatic/hydraulic slideway
Oil film supports moving parts, almost zero wear, used for mirror grinding or heavy-duty boring machines, but demanding on the oil supply system.
On September 3, 2025, China solemnly commemorated the victory in the War of Resistance Against Japanese Aggression and the World Anti-Fascist War. Behind the pageantry that displayed national strength and a commitment to peace, countless Chinese manufacturers are injecting their craftsmanship and cooperative spirit into the global economy. JSWAY CNC COMPANY is one of them, answering the call for peace and development in its own way.
For two decades JSWAY has focused on high-configuration, high-precision, high-speed CNC lathes and Swiss-type lathes. Products now reach more than thirty countries and regions, illustrating the principle of “peace through development, excellence through quality.”
True high-end manufacturing is not only technological breakthrough but also stability of quality. JSWAY’s plant houses about forty thousand square metres of floor space, producing Swiss-type lathes, turn-mill centres, gang-tool lathes and turret lathes. Critical components are machined on horizontal machining centres, gantry-type five-face machining centres and precision grinders, ensuring consistent accuracy.
An engineering data centre and joint laboratory use laser interferometers, eddy-current displacement testers, wireless rotary axis calibrators, high-precision digital temperature sensors and real-time machine-error compensation systems to upgrade products continuously.
