Precision Turning Feature

First, you need to understand what precision turning exactly is before delving into the details. Precision turning involves removing excess material from a workpiece to reduce its size and bring it to the desired dimensions to fit where needed. So basically it's a matter of cutting off the excess material to get the desired shape of the material.

Precision machining processes before the invention of CNC

In the early days before the invention of CNC machines, workers were still able to achieve precision in machining processes like tapering, turning, cutting, drilling, etc. To achieve a high level of precision, they also used various traditional tools such as blades, rockers, hammers, etc., but this process required more work and more time. As technology advances, so do techniques that increase the level of precision. We can now perform precision machining processes on many materials such as wood, metal, plastic, etc.

Advantages of Precision CNC Machining

CNC is an innovation in the precision machining process because it can perform multiple high-precision processes at the same time, such as: B. Precision turning. It has a small numerical computer that is programmed according to the needs and then the machine executes all the processes according to the program sent back to the computer. A special technician and operator are required to operate the machine smoothly and safely. In our daily lives, aluminum is CNC machined daily in most factories. Compared to traditional machining processes, CNC machines offer many advantages, some of which are listed below:

High Precision and Accuracy – Produce highly accurate and accurate parts in less time.

Time saving – Very fast process compared to conventional machining processes

cost cutting – Short staff due to less work and fewer resources.

Safety – As there is no need to interact with machines, it is very safe compared to previous machining processes. And with the CNC machine, you just enter the program into the computer and the machine will do the rest of the work.

High precision CNC turning

Firstly, it is necessary to define what CNC turning is. CNC turning is a process of producing detailed turned parts using a lathe. CNC turning is a sophisticated engineering machine process used to create and produce more detailed parts for a variety of purposes. The basic methodology is the same as on a traditional lathe, but on a CNC lathe everything is computer controlled, i.e. the motor speed, the cutting tool speed, and there is no risk of error.

With the help of modern CNC lathes and CNC components, the smallest details can be manufactured to very tight tolerances into the desired job. The lathe is fully controlled by a computer program that tracks all machining processes in operation.

Difference Between CNC Turning and CNC Milling

Both CNC milling and CNC turning allow the user to produce high-precision custom parts with minute details and perform these jobs with high precision.

CNC milling requires the user to enter the program into the computer and then run it. The spindle then rotates along the axis and uses precision turning to precisely cut off excess material to produce turned parts. With computer programming you can make precise and sharp cuts.

Precision Turning-7

CNC turning uses computer-controlled machines to shape a specific end product. This method uses a single-bladed cutting tool mounted parallel to the workpiece to remove chips. The tool rotates at dynamic speed and the tool cut moves to form cylindrical cuts with true dimensions. No circular or hollow shapes are made from larger pieces of material. It is an automatic method and speeds are changed for greater accuracy rather than rotating the shape manually.

Which parts need to be turned with high precision?

There is no doubt that CNC turning and CNC milling are different processes and produce different results in the end. CNC centers are more suitable for small volume production and especially for prototypes larger than 0.25D, while turning centers are suitable for prototypes larger than 0.25D. All of them must be checked individually depending on the part product and definitely have an impact on the price of the part. If you need to make parts and don't know which process to use, CNC milling or CNC turning, you should seek a second opinion.

High precision CNC turned parts or specialty parts are highly sought after in almost all industries including automotive, biomedical, aviation, instrumentation, robotics and many other industries.

Ultra-precision machining: a new innovation

Ultra-precision machining is an innovation in precision machining that allows machines to perform precise machining on a micro level. The ultra-precise CNC machine was originally developed to precisely machine metal optics with very tight tolerances. In recent years, diamond cutting tools, machining processes and part materials have achieved a greater degree of flexibility due to new advances.

Finish difficult turning

Finish hard turning involves single point cutting of hardened materials whose hardness is in the 2 micron range between 54 and 67 HRC. It is a simple, very good and reliable technology in grinding technology. Finish hard turning offers very significant advantages over conventional cylindrical grinding.

Cost cutting – It performs multiple tasks in one configuration that are performed on other machines and ultimately saves costs.

Low Tolerances – This process produces parts with very low tolerances.

High production – Compared to traditional methods, parts are created in less time, resulting in greater production.

flexibility – Hard turning with finishing can produce parts with different contours and sizes. This guarantees more flexibility in production.

Environmentally friendly – ​​Hard turning is a refined, dry process that results in an environmentally friendly process.
