The Lathe machine has been used by humans for centuries now; however, not everyone understands or knows what exactly this machine is, mainly due to ignorance. No doubt, we have come a long way in using technology for our benefit, and we humans always have to improve our technologies. For instance, music players such as boomboxes and radios are replaced with much smaller and efficient devices. Similarly, even though lathes have been around for centuries, we have managed to enhance the efficiency of these machines, and they are still used in the manufacturing industry today.
Today we are in the era of CNC lathe machines that can operate much efficiently and with minimal manual intervention. CNC lathes are quickly replacing the traditional manual lathes and semi-automated lathes such as the multi-spindle lathe. The flatbed design of CNC lathes enables them to operate and set up with ease. Used CNC machines for sale can be controlled by uploading the coded instructions to the CNC control. Nevertheless, CNC lathes have somehow managed to bring enhanced power and versatility to the primitive lathes used by the Romans and other ancient civilizations.

Types of CNC Lathe Machines
The fact that there are different types of CNC lathe machines often comes as a surprise to many people. Of course, there is no denying that all of these are more or less similar in terms of functions and operations, but there are still some differences that one must know before purchasing a Doosan lathe. There are four main types of CNC lathe machines:
- Engine lathes: This is the most commonly used CNC lathe machine as it is very well suited for both high power and low power operations. Moreover, this machine is available in various sizes, with some coming at a staggering size of 60 feet in length. Engine lathes may not be as sophisticated as the other variants, but still, most CNC shops are using this machine as it can be used to cut any material with ease.
- Tool Room Lathes: As one of the most versatile CNC lathe machines, the tool room lathes provide perfect finishing to the workpiece. Moreover, these machines are perfectly suited for manufacturing processes as it more speed and are equipped with different feeds.
- Speed Lathes: Speed lathes are known for having a simple design as these machines are equipped with a single tailstock, headstock, and tool post. Even though the spindle speed of these machines is relatively high, the overall operation can be carried out at just three to four speeds. Speed lathes are typically used for lightweight machineries such as woodturning, metal spinning, and metal polishing.
- Turret Lathes: Turret lathes are perfectly suitable for fast and quick operations as these machines are seated on a single structure with different tool posts. The singular setup of the machine enables it to get the job done as soon as possible. The operator does not have to worry about errors caused by misalignment as terret lathes do not move the workpiece.
Things to Consider Before Buying a Used CNC Lathe Machine
CNC lathe machines are great for enhancing the production capabilities of the business. However, these are often very expensive and may get difficult to manage the required finance to buy a CNC lathe machine.
But what if we had a more feasible way to purchase a CNC lathe machine without emptying the entire savings? Well, there is no need to panic as there is a way to get hold of a CNC lathe machine without spending the entire financial resources of the business in a single machine. The alternative here is to go for a used CNC machine as these machines are often just as good as new in terms of quality and efficiency.
However, some things must be considered before making the final decision to buy a used Doosan CNC lathe machine for sale. A few of these considerations are:
- Spindle and Bearings: It is best to run the machine at high speed once and evaluate the spindle and its bearings. One must refrain from buying a CNC lathe machine with overheating bearing and unusual sounds.
- Timing belt: CNC lathe machines equipped with gears are supposed to have a timing belt across the motor to the headstock. It is vital to run the machine and check any form of abrasions at the best timing to avoid any possible losses.
- Bed Ways: Often known as the most-centric component of the CNC lathe machine, the bed ways are located in the headstock. This component is supposed to go through the usual wear and tear with time, so it is best to test the machine beforehand to determine the degree of unevenness.
- Back Gears: The back gears can be found on the headstock, and it is a must to check these gears for any broken or worn-out teeth. However, the back gears are not easy to access, so it is best to run the machine and keep ears open for listening to any unusual sounds.
- Axes: The X, Y, and Z of the CNC lathe machine are crucial for the machine to function efficiently. Therefore, it is highly recommended to evaluate the condition of axes and see if any oscillation or abnormal noise is coming from the axes. Also, try listening to each of the servo motors to check for any high-pitched humming sound as it may indicate some sort of abnormality.
Conclusion:
The development of industrial manufacturing is driving the demand for more automated and efficient methods to manufacture products. CNC lathe machines are playing an important role in fulfilling the huge demand. More and more businesses are replacing the traditional manual procedure of manufacturing goods with faster automated processes. Furthermore, CNC lathe machines can be useful in making different products, but they are particularly best suited for developing products with a spherical or cylindrical shape.
Hoping that this information can be of help to someone looking forward to buying a CNC lathe machine. Many experts recommend going for a reliable brand when choosing a CNC lathe machine so kindly check out Doosan CNC lathe for sale.
