Micro turning

Types of micro turnings

The micro turning process applies to metals, but it can work on thermoplastic polymers and ceramic materials. Various materials used for micro turning include titanium alloys, brass, inox, hardened steel, and aluminum. These micro turning parts will suit the automotive, medical, and aviation industries that need specific components.

Micro turning equipment can work on different shapes, like hexagons, round shapes, ornaments, and custom designs. The machinery can be a CNC or Swiss-type lathe. CNC is computer-controlled, while Swiss-type relies on a sliding headstock that moves continuously.

Since the definition of micro turning parts can differ, it's best to clarify that micro turning means parts with a diameter below 0.8 millimeters. These ultra-precise turned components are also known as precision machining. The types of micro turnings include;

• Solid screws: These turned parts are typically cylindrical with threads along the shaft. They are solid in the sense that they do not have a vacant or hollow center. Despite their small size, the solid screws have a significant role in machinery and electronic devices.
• Micro brackets: These turned parts are L-shaped brackets that provide support and are instrumental in guiding and securing connections between other components. They are mainly used in the aerospace and automotive industries for micro brackets jobs.
• Micro-spacers: These turned components are small cylindrical parts that fill the space between two objects. They ensure proper alignment and gaps in mechanical assemblies, mainly in the aerospace and automotive sectors.
• Housings: The micro housing is a shell that can protect and house essential parts in the lathe machine. These components can include sensors and other electronic devices. Since they are very small, they can also be used to house and keep circuit boards safe.
• Rotary shafts: These turned parts are long with a small diameter. They are important in connecting components that need to rotate together.
• Pins: These micro parts can come in different shapes; some have a head, while others are tapered. They play a significant role in locating, aligning, and fastening components together.
• Valve parts: These micro parts control the flow of fluids in machines. They ensure that other machines operate smoothly; without them, there could be leaks and more fluid than necessary.

Functions and Features of Micro Turning

• Micro-Spindle Precision Control:

  The micro turning process involves a precise spindle that can rotate really fast and hold the small part tightly. This spindle's speed and grips allow for accurate turning to create small features or shapes on the parts.

• Embedded Digital Automation Systems:

  Micro turning machines often have automated systems that use computer programs to control all the detailed movements and actions of the machine. These automated systems ensure that the micro-sized features are produced consistently, and accurately, and in an efficient manner.

• Cutting Tool Miniaturization:

  The size of the tools used for turning are really small so that they can precisely shape and trim small parts. These mini tools allow for effective material removal and the creation of fine details on the parts.

• Microscale Surface Finishing:

  After a part is shaped, there may be additional processes to smooth out surfaces or improve finish quality at the micro-level. This ensures that all tested properties meet the necessary standards.

• Microwave Materials Processing:

  Some turning machines use microwaves to heat and treat small materials during production. This helps improve the characteristics, qualities, or properties of the micro-sized parts being made. The heating enhances the durability and performance of turned parts.

• Environmental Chamber Compatibility:

  Micro turning requires a controlled work environment with precise temperature and atmospheric control, enabling accurate and consistent micro-manufacturing. This facilitates the successful production of micro-turned parts.

• Lubrication Technology Integration:

  An effective lubrication system reduces friction during the turning process, improving tool life and surface finish of the turned parts.

Applications of micro turning

The impressive precision and micro machining capabilities of micro turning make it an ideal choice for industries and applications that need small parts or components. The following list shows some industries where micro turning is useful:

• Medical industry: The micro turning process is instrumental in manufacturing tiny screws, valves, and other minute components for pacemakers, orthopedic implants, and various other medical devices.
• Aerospace: Aerospace manufacturers use micro turning to produce small parts that help with sealing, valves, and actuators in drones and airplanes.
• Automotive: When making parts for fuel injection systems, transmission, and electronic controls, the automotive industry also makes use of micro turning.
• Electronic:/consumer electronics: Micro-turning is widely used for producing small connectors,响应器 o 6 dL 7h r a tiresels and housing components for smartphones, glasse sheets, etc.
• Jewelry/Cosmetology: Jewelery manufacturers use micro turning to create detailed designs and intricate patterns. Micro turning is also used to make small shells for beauty products.

From the list, it is clear that micro turning is useful for several industries and applications. As technology and techniques improve, the demand for micro-turned parts will increase. This is because precision manufacturing is required in more applications, especially those in the medical sector. Other sectors with growing demand are aerospace and automotive. Micro-turning will continue to be relevant in industries that require detailed work, especially in hard-to-handle materials. As global markets grow, business buyers can source micro-turned components from Alibaba.com at a good rate. They can also find equipment to do the micro-turning in-house.

How to choose micro turning machines

• Target industry:

  The turning machine serves many industries. These include manufacturing, medical devices, electronics, and the defense. A peek into the buyers' market can reveal the industry that demands turned parts. This can help one choose a turning machine that specifically serves this industry.

• Machine complexity:

  A simple lathe machine can handle basic micro machining turning tasks. CNC turning machines are more complex than manual lathes. They can do more tasks than a simple lathe turning machine. The CNC turning machine features a computer-controlled system. So, it engraves, cuts, and finishes with precision. Beginners or small workshops can start with simpler machines. As the business grows, one can invest in more complex turning machines.

• Production volume:

  Low production volumes need less robust machines. These machines can handle turning tasks. High production volumes call for precision, speed, and reliability. So, manufacturers producing in large volumes may need more advanced turning machines.

• Material compatibility:

  A wide range of materials need micro-machining to get the final part. These materials may include metals, plastics, and composites. Each material requires a specific micro turning machine . For instance, a CNC lathe machine can cut metals like steel, aluminum, and titanium. A CNC turning and milling machine can do more tasks on plastics and composites.

• Machine precision:

  Precision is vital for micro parts. So, manufacturers need to pay attention to the machine's tolerance level. A simple lathe machine works well for parts that don't need high precision. For high accuracy, the turning machine must have a tight tolerance level.

• Available features:

  Extra features increase the flexibility of turning machines. These features include live tooling, sub-spindle, bar feeding, and automated loading. Manufacturers should assess their needs and choose a machine with the required features.

• Budget and cost-effectiveness:

  Advanced turning machines cost more than basic models. But, they offer more value. A used lathe in good condition is a more affordable alternative. One can also cut costs by buying turning machines without extra features. Choosing a machine with lower running costs is also a reasonable option.
