CNC machines employ software applications to ensure the precision, accuracy, and optimization of custom-designed products and parts. CNC machining is familiar in the past times for manufacturing useful components. But the increased development has also made CNC machining more complex, reliable, and efficient.
CNC controls and operates multiple tools. It can accommodate workpieces that produce components with higher accuracy, durability, and functioning. We are here discussing the CNC lathe machines that help you to understand these machines better.
What is CNC Lathe Machine?
CNC lathe machines are those machines that give a definite shape to the components through accurate cutting by lathe tools. It mainly operates with computer numerical control systems that provide the instructions for a definite component design.
These machines manufacture precise round shapes with an inner diameter and outer diameter. These machines are used in medical, paper mills, aerospace, oil and gas, power plant, and automotive industries.
The cutting is done according to the given instructions. It is mainly used in spinning, glass, metal, wood turning, etc. Turning refers to the rotating action of the workpiece and certain types of machines called CNC turning machines. A simple lathe can operate on two axes using a cutting tool in a fixed position.
It can perform the operations such as tool deformation, knurling, cutting, sanding, etc. A lathe having computer numerical control is called a turning center.
Various components of the lathe machine provide the demanded design through their functioning. The main components of the CNC machine are described below.
How Do CNC Lathes Work?
CNC lathe machines work by mounting and moving the cutting tool on different axis for the precise cutting of the workpiece that rotates by the main spindle. It results in the production of precision components with cylindrical or circular shapes with the desired diameter.

The programming directs the controller to function with the drive motor and helps work different components along with moving the shaft to complete a particular design.
Before starting the operation, carefully check the machine to eliminate any troubleshooting. The next step involves uploading the G-code computer file to the CNC lathe and installing a cylindrical material block. The operational capabilities of the Lathe are facing, grooving, thread cutting, and boring.
This cylindrical material block is then kept safe in the chuck. After that, rotate the workpiece and chuck by setting the speed of the spindle.
Make sure the absence of any discrepancy checks the spindle speed and the rotating workpiece. After checking them, locate the cutting tool and move both the carriage and the tool turret.
In the end, perform the cutting operation by moving the carriage. It also involves the removal of extra material to attain a smooth, accurate machined part.
What is CNC Lathe Machine Types?
Different CNC milling machines are available for machining operations, such as a 3-axis lathe that can perform 3-planes, tapping, and helical milling operations, and a 3-axis lathe to the basic X and Z axis, life tool, and C axis is added.
A 2-axis CNC lathe can perform the cutting of the diameter of the workpiece but is not good for milling operations. Now we will look into the classification of CNC lathe machines based on lathe spindle position, several tool holders, and the functions of CNC lathe machines. Some main components are described below.
Certain types of CNC machines, also called CNC turning centres, produce a versatile range and more complex parts through rotating and cutting components using an outer and inner diameter. The 2-axis CNC lathe has a Z-axis and X-axis to cut round parts. Some types are:
Classification by Lathe Spindle Position
A CNC lathe machine is classified into two types based on its spindle position.
(a) Vertical CNC Lathe
The vertical CNC machine is commonly used for workpieces that have large sizes and are heavier. The vertical CNC lathe machine uses gravity to stabilize the workpiece. The spindle is oriented in a vertical plane in vertical CNC lathe machines. Vertical machines are also referred to as vertical boring machines sometimes. The major components of Vertical machines include:
Vertical machines are quite capable of producing chucked parts. In vertical CNC machining, the parts stay in place because of gravity, unlike other conventional processes. The vertical CNC lathes can meet the increasing demands of the present industry.
One of the reasons for using such machines is their benefits over a standard milling machine. Vertical CNC lathes can perform milling and drilling operations like siding, rocking, crosscutting, or perching. Vertical CNC lathes allow clockwise and anticlockwise rotational operations.
(b) Horizontal CNC Lathe
Horizontal CNC lathes are those machines in which the spindles are oriented in a horizontal position. Horizontal CNC machining is known to be the first machine tool in the world.
The horizontal CNC machine is commonly used to cut cylindrical parts and shapes, and the horizontal CNC turning machines ensure faster cutting while maintaining good accuracy in production. The horizontal modern CNC lathes are strong and sturdy and can promise good performance.
The horizontal CNC lathe machines are quite common in manufacturing industries all over the world due to higher precision in their cutting.
The two major horizontal CNC machines are wooden lathes and steel lathes.
Classification of CNC Lathe Machining Process by the Number of Tool Holders
The Turret Lathe only takes seconds to perform a job. The Turret machine consists of the parts like bed, headstock, clutch, legs, chuck, spindle, seed rod, and cross slide. There are many advantages of the Turret machine, some of which are as follows:
(a)Single-Turret CNC lathe
In case of massive parts or bulk production, the automatic Lathe is quite useful. This Single Turret Lathe is a good choice when we are planning for the production of identical or duplicate parts.
While machining materials like steel, aluminum, and plastic, we will require a turret Lathe to fill our needs fully. A single turret Lathe is beneficial because it is easy to use and promises accuracy, precision, and reliability.
Nowadays, automatic turret Lathes have replaced the Manual turret tool. The automatic turret lathe has become very useful in the manufacturing industry because it has increased productivity and reduced the machining time. Hence the need for a highly skillful operator is not required anymore.
(b) Double Turret CNC lathes
Unlike the single turret CNC machine, a double turret CNC lathe uses a four-axis during a machining operation. The double turret allows simultaneous cutting by the CNC machine tools on the upper and lower turrets.
A second turret is added to a 3-axis CNC machine and has an upper and lower turret to pick up the part. They have two linear axes. One Y-axis is at the upper turret, and the second spindle moves towards the main and rotating spindle. To complete the cutting operations, the second spindle is separate from the main spindle.
One turret's lagging does the workpiece cut to the other as they move down. It results in the production of double the amount of chips during machining as compared to the single Lathe.
Moreover, they may have a slanted machine bed. This design allows the collection of more hot coolants and hot chips in the lower turrets. It directly affects its accuracy, making it more accurate than a single turret CNC lathe.
