Automatic Traub Machine PAT-25

PENTAGON Single Spindle Automat Machine Traub Model PAT-25 with all standard accessories listed

About the Machine: (Also known as Single Spindle Automatic Lathe / Traub Type Automatic Machine)

A Traub machine is a type of single-spindle automatic lathe renowned for its precision and efficiency in high-volume machining operations. Originally developed in Germany, these machines have evolved into versatile platforms used across various industries, including automotive, medical, and electronics manufacturing.

Features:

1. Automatic Operation: Fully cam-controlled operation for continuous production without manual tool movement.
2. High Productivity: Capable of producing hundreds to thousands of components per shift due to automatic cycle repetition.
3. Precision Machining: Produces parts with close dimensional accuracy and excellent surface finish.
4. Multi-Operation Capability: Turning, facing, threading, drilling, boring, grooving, and knurling can be performed in a single setup.
5. Compact & Rigid Design: Heavy-duty cast iron bed ensures vibration-free operation and long machine life.
6. Bar Feed Mechanism: Automatic feeding of bar stock ensures uninterrupted production.
7. Adjustable Cams: Quick changeover for different job settings; easy to modify cutting cycles by changing cam profiles.
8. Coolant System: Integrated coolant circulation ensures better tool life and smooth surface finish.
9. Safety Features: Protective guards, automatic stop on bar end, and overload protection.
10. Low Operating Cost: Requires only one semi-skilled operator to supervise multiple machines.

Applications: Traub machines are widely used for mass production of precision turned parts where high accuracy and repeatability are essential.

Components Produced:

1. Hex bolts & studs
2. Spacers & sleeves
3. Threaded pins and bushes
4. Grease nipples
5. Small shafts
6. Brass components
7. Special turned parts for CNC or assembly use

Advantages

1. High production rate for small turned parts.
2. Excellent dimensional repeatability and surface finish.
3. Low skill requirement once cam setup is done.
4. Long tool life due to proper coolant and feed control.
5. Compact size and low maintenance.
6. Reliable, rugged, and cost-effective for batch production.

Limitations

1. Not suitable for complex contouring or variable machining (better handled by CNC lathes).
2. Cam setup time can be lengthy for new jobs.
3. Primarily for round bar stock.
4. Manual cam change required for different part designs.

Summary

The Traub Automatic Lathe Machine remains one of the most reliable and efficient solutions for mass production of precision turned parts.

Its robust design, automatic operation, and adaptability make it ideal for industries where speed, accuracy, and cost-efficiency are crucial. Even in the CNC era, Traub-type automats continue to be the backbone of small-component manufacturing worldwide.
