First of all, there is a need to understand what exactly precision turning is before diving deep into the details. Precision turning is the removal of extra material from a job to reduce its size and convert its size into desired dimensions so as to it can fit where we need it. So, basically, it involves cutting extra material to get desired material shape.

Precision Machining Processes before Invention of CNC

In the early days before the invention of CNC machines, workers still manage to get precision in machining processes like tapering, turning, cutting, drilling, etc. To achieve a high level of accuracy they also use different conventional tools like blades, see-saws, hammers, etc. but that process took more labor and more time as well. As the technology advances so as the techniques which also increase the degree of accuracy. Now, we can perform precision machining processes on many materials like wood, metal, plastic, etc.

Advanatges of Precision CNC Machining

CNC is a new innovation in the precision machining process because it can do various high precision processes at the same time i.e. precision turning. It has featured a small numerical computer which is programmed according to the requirements and then the machine do all the processes according to the program fed back to the computer. A special technician and operator are required to smoothly and safely run the machine. In our daily life, CNC almunium happens in most factories every day. As compared to conventional machining processes there are many advantages associated with CNC machines and a few of them are listed as below:

High Precision and Accuracy – Product extremely accurate and precise parts in less time.

Time-Saving – Very time-saving process as compared to conventional machining processes

Cost Saving – Low cast because of less labor and fewer resources.

Safety – As you don’t have to interact with machines so it’s very safe as compared to previous machining processes. And in the CNC machine you just have to feed the program in the computer and the rest of the work is for the machine.

High Precision Turning with CNC

First thing is to define what is CNC turning? CNC turning is a process of manufacturing detailed turned parts with the help of a lathe. CNC turning is a highly skilled engineering machine process to create and manufacturing more detailed parts for different purposes. The basic methodology is the same as used in a conventional lathe but in CNC lathe is controlled by computer everything is controlled i.e. speed of the motor, cutting tool speed and there is no chance of mistake.

Using modern CNC Turning lathe and CNC components very minute details can be crafted on the required job with very low tolerances. The lathe is all controlled by a computer program which keeps track of every machining process on the job.

Difference between CNC Turning and CNC Milling

CNC milling and CNC turning both allow the user to create high precision custom machined parts that involve very minute details and do work on that job with high precision.

In CNC milling user has to set and feed the program in the computer and then set it to run. The spindle then rotates along the axis and precisely cuts extra material by doing precision turning to create turned parts. With computer programming, you can make precise and sharp cuts.

While CNC Turning uses computer-controlled machines to form a special final product. The method uses a single-point cutting tool that is mounted parallel to the job to remove chips. The tool is revolved at dynamic speeds and also the tool cutting traverses to form cylindrical cuts with actual measurements. It’s do not produce circular or hollow shapes from larger material items. It is an automatic method and speeds will be changed for larger accuracy instead of turning a shaper by hand.

Which Parts Needs High Precision Turning?

There is no doubt that CNC turning and CNC milling are both different processes and in the end, both end up with different results. CNC centers are best for short volume production and mainly for those prototypes which are above 0.25D while turning centers can work for prototypes above 0.25 D. They all need to be checked individually according to part product and it will definitely impact the price of parts. If you need some parts to be manufactured and you don’t know which method is to be used CNC milling or CNC turning then you should go with a second opinion.

The High precision CNC turning parts or custom parts have high demand in almost all industries including the automotive industry, biomedical industry, aeronautics, instrumentation, robotics and many other industries.

Ultra Precision Machining: a new innovation

Ultra-precision machining is a new innovation in precision machining in which machines can do precise machining at the micro level. The ultra-precision CNC machine was originally developed to do precise machining of the metal optic with very low tolerance. During the last few years diamond cutting tools, machining processes and workpiece materials are reached to a higher degree of flexibility due to new advancements.

Finish hard turning

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

Cost-saving – It performs multiple tasks in one-setup that is done on other machines and ultimately saves cost.

Low Tolerances – This process produce parts with very low tolerance.

High Production – It creates parts in less time as compared to conventional methods so ultimately results in higher production.

Flexibility – In finish hard turning different parts of different contours and sizes can be produced. This provides more flexibility in production.

Environmental Friendly – Hard turning is a refined and dry process results in environmentally friendly process.
