FAT PONAR Parallel Lathe: What it is and How it works

The parallel lathe is a machine tool used for mechanical processing on cylindrical or conical shaped pieces. FAT PONAR is a brand known for the production of robust and reliable lathes, suitable for industrial processing. This type of lathe is used for turning, threading, boring, and grooving operations, among others.

Construction and Components of the Parallel Lathe

A parallel lathe is made up of various main components:

1. Bed : The main structure of the lathe, on which all other parts are mounted. The bench of the model in question is 2100 mm long.
2. Bar Passage : This is the maximum diameter of the bar that can pass through the chuck. For this model, the bar passage is 80 mm.
3. Chuck : The component that grips and rotates the workpiece. The diameter of the chuck is 400 mm.
4. Tailstock : A tip mounted on the movable carriage that supports the free end of the workpiece, essential for long workpieces.
5. Rest : An additional support used to support the workpiece, especially when it is long or thin.
6. Carriage : The moving part of the lathe that carries the tool along the longitudinal axis of the piece.
7. Tool turret : Where cutting tools are mounted, allowing the operator to change tools quickly.
8. Motor and transmission : Provide the power needed to rotate the spindle and move the carriage.

Workable Materials

The parallel lathe can process a wide range of materials, including:

• Steel : For the production of strong and durable components.
• Aluminium : Ideal for light workpieces and high-speed machining.
• Brass and Copper : For applications requiring high conductivity or corrosion resistance.
• Plastic : Plastic materials for lightweight or insulating components.

Mechanical Formulas for Calculating the Number of Revolutions

The number of revolutions (n) of the spindle is essential to obtain correct machining and is calculated using the following formula:

Where:

• V = Cutting speed (m/min), depends on the material and the tool.
• D = Diameter of the workpiece (mm).

Types of Tools and Processes

1. Turning tools : For reducing the external diameter of a workpiece.
2. Threading Tools : For creating internal or external threads.
3. Reamers : For finishing pre-drilled holes.
4. Groovers : To create grooves or notches in the piece.

Common processes include:

• Cylindrical turning : Reduction of the diameter of a cylindrical workpiece.
• Threading : Creating internal or external threads.
• Reaming : Refinement of existing holes.
• Cutting and separation : Cutting a section of the machined piece.

Maintenance of the Parallel Lathe

Correct maintenance is essential to keep the lathe in good condition and prolong its useful life:

1. Lubrication : Regularly lubricate all moving parts, such as the table guides and spindle.
2. Cleaning : Remove chips and debris from guides and gears to avoid wear and blockages.
3. Checking alignments : Periodically check the alignment of the chuck and tailstock.
4. Checking Oil Levels : Monitor and change the oil in the spindle and drive lubrication system.
5. Inspection of belts and gears : Check that they are not worn or damaged.

Why it is better to buy a used FAT PONAR parallel lathe

1. Economic savings : Used lathes cost less than new ones, reducing the initial investment.
2. Quality and robustness : FAT PONAR lathes are known for their durability; a well-maintained used model can offer almost like-new performance.
3. Reduced depreciation : A used lathe has already suffered the most depreciation, making the investment safer.
4. Immediate availability : Purchasing a used lathe eliminates waiting times for the production or delivery of a new model.
5. Proven Reliability : A used lathe that has a documented history of maintenance is often a reliable choice.

In conclusion, a FAT PONAR , like the one described, represents an excellent opportunity for those looking for a reliable and robust machine without having to face the costs of a new model.
