The Jinling lathe model CW 62143 C 4500 is a machine used mainly for mechanical processing of metals, in particular for turning long and heavy pieces. Below is a complete overview of its operation, use, types of existing lathes, workable materials, alternative machinery, calculations to optimize operation, and reasons why it might be convenient to buy a used model.

How it works and how to use a lathe

A lathe works by clamping a piece of material onto a rotating chuck, while a cutting tool (such as a turning tool) is brought closer to the piece to remove material in a controlled manner, creating the desired shape. The Jinling CW 62143 C 4500 is designed to machine workpieces up to 4500 mm long, and is particularly suitable for turning shafts, cylinders and other long components.

Phases of use:

1. Fixing the workpiece: The workpiece is mounted on the lathe chuck and fixed in place.
2. Tool Setup: You place the cutting tool in the tool holder and adjust it to get it closer to the workpiece.
3. Starting the machine: The spindle begins to rotate and the tool is gradually advanced against the workpiece to remove material.
4. Process Control: The operator monitors the process to ensure the part is machined accurately.
5. Finishing: Once the desired shape has been obtained, any finishing is carried out to improve the surface of the piece.

Existing Types of Lathes

There are different types of lathes, each designed for specific processes:

1. Parallel lathe: Used for machining cylindrical pieces, it is the most common type.
2. Numerically controlled lathe (CNC): Programmable automated machine to perform complex machining operations with high precision.
3. Front lathe: Suitable for working on pieces that are large in diameter but short in length.
4. Vertical lathe: Ideal for working large discs or rings.
5. Revolver lathe: Used for mass production of small parts.

Workable Materials

The Jinling CW 62143 C 4500 can process a wide range of materials, including:

• Steel (carbon, alloy, stainless)
• Cast iron
• Aluminum
• Brass
• Copper
• Industrial plastic

The choice of cutting tool depends on the material being worked on, with some tools specific to hard or abrasive materials.

Reciprocating Machinery

While versatile, a lathe is not always the only option for machining. Some alternative machinery includes:

• Milling machines: Used for processes such as drilling, milling and shaping flat surfaces.
• Grinding machines: Used to obtain very smooth and precise finishes.
• Boring machines: Used to enlarge and finish cylindrical holes.
• Numerically controlled (CNC) machines: Multi-function, these machines can perform turning, milling, drilling and other complex processing.

Calculations to Optimize Operation

Optimizing the operation of a lathe like the Jinling CW 62143 C 4500 requires precise calculations, including:

• Cutting speed (V): Depends on the material of the piece and the cutting edge, and is calculated with the formula V=π⋅D⋅n1000V = \frac{π \cdot D \cdot n}{1000} $V$ $=$ 1000 π ⋅ D ⋅ n ​, D is the diameter of the workpiece and n is the spindle speed in revolutions per minute (RPM).
• Feed (f): The speed at which the tool advances along the workpiece, usually expressed in mm/rev.
• Depth of Cut (ap): The amount of material removed in one pass, important in determining the power needed and tool wear.
• Cutting power (Pc): It can be calculated to check if the lathe has the necessary power to perform the desired cut without overloads.

Why it is better to buy a used lathe (Jinling Model CW 62143 C 4500)

Buying a used lathe like the Jinling CW 62143 C 4500 can be advantageous for several reasons:

1. Economic savings: A used machinery costs significantly less than a new one, allowing you to reduce the initial investment.
2. Reliability and robustness: Lathes like the Jinling CW 62143 C are known for their durability. A well-maintained model can function effectively for many years.
3. Adaptability to needs: This model, with a maximum length of 4500 mm, is ideal for processing long pieces, offering flexibility for different types of processing.
4. Availability of spare parts: Even if the model is used, spare parts are likely to still be easily available, especially for machines from established brands.
5. Time-tested: A used lathe has already proven its capabilities, reducing the risks of manufacturing defects or teething problems that might emerge on a new machine.

In summary, purchasing a Jinling CW 62143 C 4500 can represent an economical and practical solution, especially if you need a robust and reliable machine for processing long and complex pieces.
