Multi purpose cnc lathe machine

Types of Multi-Purpose CNC Lathe Machines

A multi-purpose CNC (Computer Numerical Control) lathe machine allows the automated execution of various machining processes on a workpiece. These machines commonly have multiple heads or attachments to enable different machining tasks without needing workpiece transfers or setups. Here are some types:

• Multipurpose CNC Lathe with Attachments:

Various attachments expand the capabilities of a standard CNC lathe machine. Some standard attachments include a CNC lathe milling machine attachment, a CNC lathe metal cutting band saw attachment, a CNC cutting torch attachment, and many more. These attachments transform a standard CNC lathe into a multipurpose machining center that can carry out various machining processes on a workpiece.

• Multipurpose CNC Combined Machines:

Combined multipurpose CNC machines integrate two or more standard machining processes into a single workstation. For example, a CNC turn-mill machine combines CNC milling and lathe machining capabilities in one machine. The integrated design eliminates the need for multiple machines or workstations, reducing setup times and improving production efficiency. Some other typical combined multipurpose CNC machines include the CNC lathe with a plasma cutter, the CNC router with a milling head, and more.

• Multipurpose CNC Machines with Rotating Heads:

CNC machines with rotating heads feature an interchangeable or programmable head that can rotate. The rotating head can be transformed to perform several machining tasks, such as drilling, tapping, threading, countersinking, etc. These machines have high efficiency, precision, and flexibility in processing workpieces with different materials and shapes.

Overall, the main benefit of a multi-purpose CNC machine tool is to streamline machining processes, reduce setup times, and improve precision and efficiency in production. These machines are ideal for high-production manufacturing environments that require rapid turnaround and tight tolerances.

Specification and maintenance of multi-purpose CNC lathe machines

Specifications

• Size and capacity: Multi-purpose CNC lathes generally include standard models and small bench-top models. Standard models' typical size may be 1,500mm to 4,000mm in length and 200mm to 600mm in diameter. Their work capacity is high; however, the size is also relatively large, making them more suitable for industrial applications. The bench-top models are convenient for both home workshops and small-scale production. Their size and work capacity are smaller, which makes them more suitable for education and experimentation. For example, a small lathe may have a length of 500mm and a diameter of 200mm.
• Control system: A CNC lathes control system is similar to a computer. It plans the movement by changing G-code, which is a machine language code, to control the actions of the machine. Different control systems may use different forms of language to express the same command. Common control systems include FANUC, Siemens, and Haas. Taking the FANUC system as an example, it may be equipped with an operator panel such as "FANUC 0iT" and "FANUC 31i." These panels have screens and buttons. They are user-friendly interfaces that allow operators to easily input and change commands, as well as monitor the machine's status and activities.
• Tools and holders: Multi-purpose CNC lathe machines are equipped with various tool holders and cutting tools to complete different types of machining. Cutting tools include turning tools, drilling tools, tapping tools, etc. Turning tool holders can adapt to car knives, grooving knives, and other tool types. The CNC tool holder is capable of automatically changing tools, which makes it possible to complete more machining operations with fewer manual interventions.
• Workpiece clamping device: The workpiece fixing device of multi-purpose CNC lathes is flexible and can hold a variety of workpiece shapes and sizes. For example, it can fix round objects such as shafts and pipes by means of a chuck. It can also clamp fixed plates and other shapes through fixtures and clamps.

Maintenance

• Lubricate moving parts: Lubricate the fixed support points and the slider of the lathe by applying grease to ensure its stable operation, thus achieving smooth movement and protecting the machine from wear.
• Clean the machine tool: Wipe the lathe with clean water and a cotton cloth to remove dirt, dust, and chips in a timely manner, which can prevent foreign objects from affecting the machine's operation and the quality of the processed workpieces.
• Check electrical and air circuits: Check the electrical connections and the circuit controllers to ensure proper functioning of the machine. In addition, air compressors can provide a cooling system. A check on the air circuit can prevent failures caused by improper air pressure transmission.
• Repair and replace tooling: Multi-purpose CNC lathes are equipped with changing tools and tool holders. Regular inspection and maintenance can guarantee machining accuracy and efficiency.

Scenarios of multi-purpose CNC lathe machines

These components require small size, intricate shapes, and tight tolerances that are difficult to achieve through traditional machining methods.

• Medical device manufacturing

  Multi-purpose CNC lathes are also widely used in the medical device manufacturing industry, such as medical instruments and implants. This includes precision machining of complex shapes and tight tolerances required for medical devices, ensuring compliance with strict industry standards.

How to choose multi purpose CNC lathe machines

When choosing a CNC lathe machine for sale, it is important to create a comprehensive checklist of things that will influence the purchasing decision. This checklist helps to define the use cases and specifications for the ideal machine to buy.

When creating the list, it helps to bring in the intended audience for the CNC machine. Will it be used for custom projects or in an industrial workshop? If it is meant for an industrial workshop, a large centerpiece with automatic features will be perfect. If it is used for custom projects, small portable devices will suffice.

Next, determine the type of material the lathe will work on. The devices work on different types of materials, so buyers need to be clear about the material they will use the machine to shape. Knowing the type of material will help buyers choose a device compatible with the substance in question. This applies to the device’s construction features, such as the clamping mechanism and cutting tools.

Another important part of the checklist is the required workpiece size and weight capacity. The lathe device has different sizes and weights. The size and weight capacity of the intended machine will determine its size and weight capacity. Most full-sized CNC lathe machines can take up to 400 mm of diameter.

Be clear about the desired level of automation of the CNC machine in question. Some devices have automatic feeding, while others have it manually fed. Determine the level of automation before buying, as it will determine the cut’s accuracy and repeatability of the devices with higher automation functions.

Finally, determine the budget before purchasing a device. CNC machines with more advanced and automated features cost a lot more than those with less advanced features. Know what needs to be spent and the type of device that has to be bought to serve its purpose.
