An Introduction to CNC Turning

Whether you’re an executive looking to source parts for your products, or you’re interested in hardware and engineering, the chances are that you’ve heard about CNC turning. If not, fear not: you’ve come to the right place for a brief introduction! CNC turning involves a turning machine that uses digital codes to control and automatically process, according to a given working program, movement speed and trajectory. It’s a high-precision, high-efficiency automatic machine with digital information to control the displacement of parts and tools. The process involves rotating a workpiece to maintain a cutting movement, and different turning movements can be achieved relative to the workpiece, allowing companies like Weimi to offer clients affordable, high-quality CNC machined parts, expertly crafted and made to last.

 

What does a CNC turning processing look like?

 

  • Turning the outer circle

The most common and basic method involves turning the outer circle, using a variety of turning tools. The left side cutter is mainly used for the outer circle with a right-angled shoulder on the right side of the turning, although the outer circle cannot be turned.

 

  • Turning the inner circle

This method involves turning the inner circle or hole. This is done by using a turning machine to enlarge the hole of a workpiece or machining the inner surface of a hollow workpiece.

 

  • Plane turning

The turning plane refers to the turning end plane, including the stepped-end surface, machining the centre with a hole or the general stepped end surface using a right-biased turning plane. The cutter head is strong and suitable for turning larger planes, like casting large planes of forgings. It’s worth checking whether this is the right method for your needs.

 

  • Taper turning

The cone surface can be divided into inner and outer surfaces. At Weimi Hardware Technology, we can use it as a special form of the inner and outer circle.

 

  • Threads turning

On ordinary lathes, forming turning tools are generally used to process ordinary threads, trapezoidal threads, and modular threads.

 

Our company can help customers process lathe parts. We have various types of materials including 316, 304 stainless steel, carbon steel, alloy steel, alloy aluminium, zinc alloy, titanium alloy, copper, iron, plastic, acrylic, POM, UHWM and other raw materials. They can be processed as a complex structure with square and circle combinations.

 

Our commonly used materials in Weimi for lathe processing are aluminium alloy materials. The density of aluminium alloy materials is greatly reduced compared to the density of iron and steel materials. Therefore, the plasticity is high, the product weight is reduced, and the lathe processing is much shorter. Many customers in the field of aviation accessories are required to use aluminium materials for processing parts.

 

We can also use drills, reamers and reamers taps, dies and knurling tools on lathes for proper processing. See below a customized stainless steel shaft for one of our Korean customers.

 

 

Our company has 22 lathe machines. Each one can process products up to 150×220 mm. We typically choose this type of machine for brass parts, stainless steel parts, POM (polyoxymethylene) and other small-size parts. It helps shorten the processing cycle and increase the precision of the products. Thanks to that, we can quickly realise our customers’ sample orders, typically completing orders in as little as half an hour, for your convenience.

 

What are the machining advantages of CNC over ordinary machine tools?

There are a great number of advantages of using CNC over ordinary machine tools, such as high processing accuracy, the ability to perform and process multi-coordinate linkage and parts with complex shapes, increased productivity (typically 3-5 times more when compared with ordinary machine tools), and easy-to-control product quality. As there’s less employee involvement, CNC manufacturing can be more cost-effective and ensure consistent results.

 

At Weimi Hardware Technology, we work hard to keep our machines clean, using air to thoroughly clean machines and their electrical parts at regular intervals. We also clean the area where machines are placed every day to ensure the cleanliness of the factory and the safety of the workpiece – and to ensure that every product meets your exacting standards.
