What is CNC Turning Service
In the production process known as CNC turning service, material bars are held in a chuck and rotated while feeding a tool to the piece to remove material until the required form is attained. Subtraction machining is another name for the process, which involves removing material to create the required form.

Advantages of CNC Turning Service
Accuracy
The capability of CNC turning to adhere to requirements for accuracy and tight tolerances makes the operation popular in industries such as military, medical, and aerospace. These industries often use precision machined parts in their manufacturing processes.
The conventional manufacturing industry also finds high precision useful, even when you consider an aspect such as the amount of raw material likely to be lost due to inaccuracies.
Even where the CNC lathe doesn't meet the extremely tight tolerance requirements in some of the industries, there is a chance to enhance the accuracy of these machines. Outsourcing your CNC turning jobs to specialists is also an excellent solution to accuracy requirements.
Flexibility
The flexibility that CNC turning offers is an advantage that a modern business can use. The lathe machine can work on a wide range of materials including metal, plastic, wood, and glass. It not only allows for the use of more tools but also different settings.
Because of this versatility, many businesses choose CNC turning for their part production needs. There is also the option of integrating the CNC lathe with other cutting tools to achieve even more diverse results.
Safety of CNC Turning Centers
The safety of the CNC machinist and any other personnel within the machine shop is much higher compared to where traditional machining options are used. Since the machine is largely computer-controlled, the level of manual labor requirement is minimal.
The role of the machinist is usually only to oversee everything as the CNC turning rotates. Since the rotating parts of the CNC lathe machine are typically well covered, the chances of pieces flying out and causing injury are minimal.
Versatility
Versatility is another advantage CNC machining businesses get from using the CNC horizontal turning center. These CNC lathe machines can create parts from plastic, glass, metals, and composites.
As a result, it is the go-to solution for various manufacturing needs. Additionally, you can integrate CNC machines with several tooling options, enabling them to execute multiple machining operations.
Faster Results
CNC turning machines are essential for active manufacturing businesses that aim to gain ground in a highly competitive market. When you use CNC turning centers to execute program-specified tasks, there are lower chances of errors. Consequently, these CNC turning services help to manufacture parts faster without compromising the final product's quality.
Th CNC turning machines help businesses to achieve business objectives and mass production irrespective of the requirements. More importantly, you can get the desired components faster and in larger volumes while satisfying your customers' needs.
Excellent Tolerance
Manufacturers and engineering experts often turn to CNC turning to produce machined parts with incredibly high tolerance. CNC turning offers an excellent surface finish and high tolerances than most techniques.
As a result, manufacturers commonly use this process to add precision rotational features to components whose basic structure has been formed using a different procedure.
Cost Effective
Cost-effectiveness is one benefit that attracts most machining businesses to this process. CNC turning operation helps machining businesses save a great deal of money while offering high-quality products. This is because the process improves scalability, the efficiency of production, and assembly without wasting material.
In addition, this process saves costs as it does not require purchasing new tools to create parts. Similarly, it prevents all expenses due to accidents or work hazards.
Safety
CNC machine shops purposely comply with strict safety rules and regulations to ensure complete safety. The CNC turning operation requires less labor since the turning machine is computer-controlled (automated).
As a result, the machinist is only there to supervise the operation of the machine. Also, the lathe body is semi-closed or fully covered with protective devices. This helps to prevent particles from flying from the processed workpiece, thereby safeguarding the crew from harm.
No High Skill Requirements
CNC turning operation does not require a highly skilled operator to manage the CNC machine. A machinist can complete a course and become certified to operate a CNC turning machine. Consequently, this helps to reduce further costs of production.
Types of CNC Turning Service
In horizontal turning centers, the spindle carrying the turning tool is mounted parallel to the floor. In other words, the spindle and sub spindle are in a horizontal position in this CNC turning center.
This CNC turning center has the spindle placed in the vertical position. The turning operation on the workpiece is performed from above. Typically, the table in advanced CNC turning centers will move on the Y and X axes (horizontally), so you can achieve tri-axial machining.
In place of a spindle, the horizontal lathe comes with a horizontal arbor. The arbor holds a range of heads. This way, the horizontal lathe can produce a wide range of part sizes and shapes. Also important is the force of gravity helps maintain the cleanliness of the workpiece during the CNC machining process.
The vertical lathe is less complicated than the horizontal lathe. It sets its spindle along the vertical plane and in a fixed position. The workpiece moves along the vertical plane – up and down movement.
Based on this setup, the vertical lathe is most suited for sizeable metal plates and other workpieces that need to be machined on only one side using special rotating tools. If there is a risk of workpiece sagging, the vertical lathe is preferable to the horizontal lathe.
How does CNC Turning Service work
Changing the CAD Design File to CNC Program
The first step to a CNC turning work involves preparing a CAD file for translation into machine language. However, this preparation does not include advanced programming. It only requires some completed engineering drawing of your design. As such, using software like SolidWorks or AutoCAD helps to capture the 2D drawings of your design electronically.
Moreover, you can convert an electronic design in the CAD file format to a CAM program. Also, you can export the drawing in the CAM format using the exact software tools mentioned earlier. The manufacturing engineer can then test the manufacturability of the component using the software.
Prepare the CNC Turning Machine
Setting up the CNC turning center comes after the CAD design file conversion. There is a need for a machinist or operating personnel even though the machining process is automated. However, to prepare the CNC turning lathe effectively, here are some steps to follow:
Ensure you put off the power, as the CNC machining can be dangerous. Hence, you must be very careful and check the power switches to ensure the power is off.
Mount the part onto the chuck. The chuck holds the machined part in place during the turning operation. So, not loading the workpiece properly can result in machining complications which could be dangerous.
Load the turret properly. The turning operation comprises several tools. As a result, you have to choose the right tool for desired finish. The turret holds as many tools as possible, allowing seamless turning operation.
Maintain proper calibration. You have to place the workpiece and the tool in the correct angles/ positions to ensure that all design requirements are met.
Uploading the CNC program is the last step before beginning the turning operation. You have to upload the CNC code into the turning machine.
At this stage, there are two variables you have to keep in mind. The turning speed is the first variable. It determines the speed at which the workpiece spins. On the other hand, you need to consider the feed rate, the speed at which the cutting tool moves along a revolving workpiece or bar material.
An expert machinist must be able to determine these values because wrong estimations often lead to bad results—additionally, inappropriate estimates in certain materials result in uneven finishes or fatal damage to the workpiece.
Moreover, it would help to sketch out the shape with a high feed rate and low turning speed. Similarly, you can use a high turning speed and a lower feed rate to achieve smooth finishes and create parts with precise tolerance needs.
Manufacture the CNC Turned Parts
The production of the desired part is the final step of the CNC turning operation. However, there are various turning operations depending on the desired results. In addition, the machined part's complexity often determines the number of cycles required. Calculating the time for these cycles helps to determine the overall time spent on the component, which is vital for CNC machining cost calculation.
Generally, the turning cycle often includes:
Loading Time – A cycle may need other alternatives to load the workpiece onto the machinery even though it is part of the machine setup.
Cutting Time – It covers the time used to cut the workpiece. Factors such as cutting depth and feed rate determine the cutting time.
Idle Time – Any machining operation that has nothing to do with cutting is an idle operation. For instance, time spent changing the tool's movement, setting the turning center, etc., is idle time.
More importantly, note that the raw material used in the turning operation often affects the manufacturing process result. A component formed from metal will vary in surface roughness and functionality from that obtained from plastic.
