What is CNC Turning?

What Is CNC Turning?
Computer Numerical Control (CNC) is an intricate method for creating parts using a lathe. This method is used to create detailed patterns in metals that are difficult to do by hand. CNC turning is computer controlled to precisely cut materials into a final product. This process is able to create accurate cylindrical cuts to produce circular/tubular parts. The CNC machine cuts to ensure accuracy so the products are mass produced into precise, complexed designs.

How Does It Work?
The CNC Turning engineer decides on which cutting tools to use to set up the lathe. The engineer also chooses a clamping method to hold the material firmly in place. Next, the engineer works with the computer to tell the lathe machine to move and cut parts.
This is where the skills come in. The engineer pays attention to make sure the lathe is cutting the material properly. In order to successfully match the dimensions the engineer may use a blueprint to cut with precision.
After the material is cut, the part is sent to be assembled.

How Is CNC Turning Different From CNC Milling?
The main difference between the two procedures is the final product they create. CNC milling is computer controlled by a G-code that controls the speed and location of the movements. However, this procedure may also be performed by manual override in order to adjust the process if necessary. The machine can cut a variety of shapes moving along multiple axes. The main responsibility of CNC turning is to cut tubular parts using a single-point cutting tool inserted parallel into the material.

How Swiss Screw Machining Benefits Businesses

Businesses within aerospace, military, and automotive industries, often require high volume, precise parts to build planes, cars and radar systems. To function, these machines often need hundreds – at times – thousands of precise parts to work in harmony. 

On the surface, manufacturing a functioning machine with various parts can be costly. However, relying on an experienced Swiss screw machine shop can save your business money, time, and provide unmatched quality. Below we explain the benefits of businesses utilizing this technology. 

Swiss screw machining cost

The key to Swiss screw machines efficient, cost effective process can be attributed to how the machines work.

In preparation of manufacturing orders from 100 to 10 million parts, the Swiss screw machines are first calibrated to the dimensions of the specific part, and rarely altered until the project is complete.  More specifically, high-quality precise parts from materials such as steel, stainless steel, aluminum, brass and copper, and titanium, are produced with minimal adjustments throughout the manufacturing process – saving time and cutting production costs.

Additionally, utilizing a combination of CNC and cam driven Swiss screw machines will decrease manufacturing costs and maintain quality.
