TOS Parallel Lathe Technical Data Sheet

Brand and Model: TOS

General Description:
The TOS parallel lathe with 70 mm bar passage is a robust machine tool, designed for turning operations on large pieces. It is equipped with a bench length of 7200 mm and an effective turning capacity of 6300 mm. This lathe is ideal for heavy and precision machining, such as the production of cylindrical and threaded components, thanks to its high capacity and precision.

Technical Features:

• Bar passage: 70 mm
• Bench length: 7200 mm
• Turning length: 6300 mm
• Spindle:
  • 4-jaw chuck: Diameter 580 mm
  • 3-jaw chuck: Diameter 270 mm
• Height of tips on the bench: 420 mm
• Spindle speed: Variable, typically in the range of 25 to 1800 rpm (RPM)
• Pallet material: High resistance cast iron, with ground and hardened guides
• Components Included: Guards, bezel, half moon, and tailstock

Main Components:

• Pallet: Built in cast iron to ensure stability and reduce vibrations during operation. The guides are ground to ensure precision in the movement of the carriage.
• Driving head: Contains the spindle transmission system and the gearbox, allowing the rotation speeds to be varied.
• Spindle: Mounted on roller bearings, guarantees precise and reliable rotation. It is equipped with jaws for locking the pieces.
• Counterhead: Mobile, it can be fixed on the pallet guide and used to support the piece being processed or for drilling and threading operations.

Workable Materials:

• Steel
• Cast iron
• Aluminum
• Metallic alloys
• Hard plastic

Maintenance: To keep your lathe in optimal condition, it is essential to follow regular maintenance:

• Lubrication: Ensure that all lubrication points, such as guides and screws, are regularly greased.
• Cleaning: Regularly remove chips and metal dust from the guides and moving parts to avoid premature wear.
• Alignment check: Periodically check the alignment of the chuck and tailstock to ensure precision in machining.
• Inspection of the jaws: Check the wear of the chuck jaws and replace them if necessary.

How to Evaluate a Good Used Car:

• Pallet condition: Check for signs of excessive wear or deformation.
• Headstock accuracy: Test the spindle for any play or vibration during rotation.
• Original components: Make sure that all parts, especially the rests and tailstock, are present and in good condition.
• Documented maintenance: Request maintenance history to evaluate how the machine has been treated over time.

Sectors of Use:

• Mechanical workshops
• Production of large industrial components
• Repair and maintenance of machinery
• Processing of unique pieces or small batches

Why It's Better to Buy Used: Buying a used TOS parallel lathe can be a convenient option for several reasons:

• Reduced Cost: A used lathe can cost significantly less than a new one, while maintaining high quality and functionality.
• Immediate availability: Used lathes are often available immediately, reducing waiting times compared to ordering new machines.
• Tested reliability: A used model with a good maintenance history demonstrates its durability and reliability over time.

In summary, the TOS parallel lathe represents a solid choice for precise and heavy-duty machining, and purchasing it used can offer excellent value for money, especially if carefully evaluated for its mechanical and historical condition.
