Traub lathe machine stands out as a reliable, efficient, and versatile solution for manufacturing small to medium-sized parts.
Known for its automatic single spindle operation and cam-based mechanism, the Traub machine is widely used in industries requiring high-volume production with tight tolerances.
This blog will explain the working principle of the Traub lathe machine, its key components, operation process, and industrial applications — helping you understand why it remains a popular choice in modern machining.
What is a Traub Lathe Machine?
A Traub lathe machine is a type of automatic lathe designed primarily for turning operations. Unlike traditional manual lathes, Traub machines use a cam system to control tool movement and part feeding automatically, enabling continuous and precise machining of cylindrical components.
It is often referred to as a single spindle automatic lathe because it holds one workpiece at a time but can perform multiple machining tasks automatically without manual intervention.
To understand its role better, it helps to first grasp lathe machine fundamentals, which explain how rotating the workpiece against cutting tools shapes the material.
Working Principle of a Traub Machine
The core of the Traub lathe’s operation is its cam-driven mechanism. Here’s how it works:
- The machine has three main shafts powered by an electric motor.
- Each shaft rotates at a specific speed, and cams mounted on these shafts control the movement of cutting tools and workpiece feeding.
- The cams are precision-machined to create specific motion patterns, which translate into the linear or rotary movements of tools.
- As the spindle rotates the workpiece, the cam mechanism automatically moves the tools to perform turning, facing, threading, or other operations.
- Once a machining cycle is complete, the finished part is ejected, and a new raw workpiece is loaded to repeat the process.
This cam-based automation allows the Traub machine to produce high volumes of identical parts with great accuracy and minimal human supervision.

Components of a Traub Lathe Machine
Understanding the key parts will help you grasp its working better:
- Spindle: Holds and rotates the workpiece at variable speeds. You can find precision spindles for Traub machines that ensure smooth rotation.
- Camshaft: Contains cams that guide the tool movements.
- Tool Post/Tool Holders: Position cutting tools for operations like turning, threading, and drilling.
- Chuck: Secures the workpiece firmly. High-quality collet chucks are essential for firm gripping.
- Feed Mechanism: Moves the tool or workpiece based on cam instructions, often supported by feed fingers for efficient loading.
- Gearbox and Motor: Provide power and control speeds of spindle and camshafts.
- Control Panel: Used for starting, stopping, and setting machine parameters.

Step-by-Step Working Process
- Loading the Workpiece: The operator or automated feeder loads the raw material into the chuck, often using collet sleeves or split sleeves for secure fitting.
- Spindle Rotation: The spindle begins rotating the workpiece at a pre-set speed.
- Cam-Controlled Tool Movement: As the spindle turns, the camshaft rotates, moving tools in programmed paths to perform machining tasks.
- Machining Operations: Tools execute operations such as turning, facing, threading, or boring in sequence, sometimes utilizing external thread collets for threading tasks.
- Part Ejection: Upon completion, the finished part is removed, making way for the next cycle.
- Cycle Repeat: The process continues automatically for mass production efficiency.
Applications of Traub Lathe Machine in Industry
The Traub lathe is widely used for mass production of small to medium precision parts in sectors such as:
- Automotive components (shafts, pins, bushings)
- Electrical and electronic parts (connectors, terminals)
- Medical devices
- Aerospace parts
- General engineering components
Its ability to consistently produce high-quality, uniform parts at high speeds makes it valuable in both small shops and large manufacturing plants. For more details on these applications, check this resource on single spindle automatic lathe applications.
Traub Lathe vs CNC Lathe – What’s the Difference?
While both machines automate lathe operations, the Traub lathe relies on mechanical cams for tool control, whereas CNC (Computer Numerical Control) lathes use computer programming to direct movements.
| Feature | Traub Lathe | CNC Lathe |
| Tool Control | Mechanical cams | Computer programs |
| Flexibility | Limited to cam design | Highly flexible & programmable |
| Setup Time | Longer due to cam changes | Short, can switch programs easily |
| Suitable For | Mass production of fixed parts | Prototype & variable production |
| Cost | Lower initial investment | Higher upfront cost |
For CNC lathes, accessories such as ER collets DIN 6499 and CNC collet chucks are often used to achieve precise gripping.
Role of a Traub Machine Operator
Operating a Traub lathe requires skill and understanding of the machine’s mechanical functions. A typical operator:
- Loads/unloads workpieces
- Sets machine parameters and cams (if adjustable)
- Monitors machining for quality and safety
- Performs routine maintenance
- Troubleshoots mechanical issues
Good knowledge of the cam system and machining processes is essential for efficient operation.
