Mini CNC Turning Machine

When it comes to mini CNC turning machines, the term is referred to as the CNC lathes which are used to remove the materials to form the desired shapes of sophisticated parts. The turning action activated by mini CNC turning machines constantly spins the pieces in mini CNC turning machines, allowing a variety of tooling operations to be performed to produce the products.

What is a Mini CNC Turning Machine?

When it comes to mini CNC turning machines, the term is referred to as the CNC mini lathes which are used to remove the materials to form the desired shapes of sophisticated parts. The turning action activated by mini CNC turning machines constantly spins the pieces in mini CNC turning machines, allowing a variety of tooling operations to be performed to produce the products. The mechanism in mini CNC turning machines is closely associated with the term “tooling”, which is performed by various cutting tools to form the unique profiles in the tooling area, such as cutting, milling, deformation, knurling, drilling, and facing.

With the advancements in machining manufacturing and machine tools developments, there are more and more specified CNC machine tools utilized in different industries. Mini CNC turning machines, which are also called mini CNC lathe machines, have obviously small size of the external machine body. They excel at producing and machining small parts, which can meet the processing requirement of tiny hardware components. 

Mini CNC turning machines are widely used for drilling, milling, tapping applications, they are also greatly suitable for processing complex copper and aluminum parts, which might be difficult in other lathes. One feature of the mini CNC turning machine is the utilization of spring chuck clip for positioning the workpiece. The style is greatly ideal for tiny pieces of the work piece clamping. The operation of this small CNC lathe is simple, one skilled operator can manipulate two or more lathes at the same time. With automatic control, they are suitable for inner and outer ring production as well as end face, cylinders, threads, and other conical surfaces.

Basic Structure of Mini CNC Turning Machine

Most of the mini CNC turning machines have horizontal lathe structure and are equipped with an effective CNC system.


● CNC System:

The computer numerical controlled commands are programmed instructions to communicate with the CNC lathes. CAD software, which refers to Computer Aided Design software, is designed to convey sequential commands to activate the operation. CNC provides a reliable and accurate machining process.


● Lubrication and Cooling:

Metal cutting, turning and drilling operations in mini CNC turning machines generate heat inevitably. To optimize the operation, product quality and consistency and also the tool longevity, automatic lubrication system and cooling system can help.


● Chuck:

The chuck or headstock is the gripping elements in mini CNC turning machines. It supports and holds the work piece while the spindle rotates both the chuck and the work piece at commanded speed. Many mini CNC turning machines are equipped with main and sub spindles, in this arrangement, the work pieces can be conveyed to different points (from main to sub spindle) in order to add additional features. As a result, mini CNC turning machines are preferred for adding unique features like drilling holes, slots or slight milling in mass production. Compared with traditional lathes, mini CNC turning machines are often more efficient and flexible in producing products with a variety of shapes, materials types, and dimensions.


● Stationary Tool Holder:

Different from some CNC milling machines which have movable holder and spindle for cutting tools that rotates during the machining process, the cutting tools held by the carriage in mini CNC turning machines are stationary. The tool holder is responsible for accurately guiding the tools to work onto the surface of the work pieces, applying forces toward the bar stock and removing the materials. With the designs of the tool holders and the devices that rotate the bar stock, mini CNC turning machines provide stability, high precision, and rigidity for various industrial applications.


How Small Can a Mini CNC Turning Machine Cut

A CNC machine with standard cutting tools can cut holes and cavities as tiny as 2.5mm or one-tenth of an inch on stock material. However, this is usually the limit since anything lower would require a different kind of machining, known as micro-machining, to perform accurately. That said, this method should only be performed on an as-needed basis.


Machining Materials

The materials of the work pieces and the physical properties can define the cutting speed, feed rate, and depth of cut in the operation. A large range of materials are available in mini CNC turning machines, such as metals, thermoplastics, wood, foam, composites, glass, and so on. The proper materials to apply to a mini CNC turning machine is highly dependent on the particular processing application and the specifications. The materials should be capable to withstand the tooling process, which means they should have sufficient shear strength, hardness, tensile strength and even resistance to chemical and heat
