CNC turning tool holders are classified according to their design configuration, which determines their specific applications in turning operations. Let's delve into the intricacies of different types of tool holders and their unique features.
Before we proceed further, it is worth noting that the proper selection of a CNC turning tool holder is crucial in CNC turning operations. It directly impacts the quality of finished products and the lifespan of the tool.
Static Tool Holders
In the world of CNC turning, static tool holders are often regarded as the workhorses due to their versatility. They hold the tool in a fixed location and are commonly used in operations like drilling, reaming, and boring. The two main types of static tool holders are:
Covered Wrench Tool Holder
Covered wrench tool holders have an adjustable clamping system that securely holds the cutting tool. Depending on the specific design, the tool holder may have clamping levers, bolts, or screws that make it possible to adjust the tool's position.
Bolt-on Tool Holder
As the name implies, bolt-on tool holders are mounted onto the machine using bolts. They are designed to hold a variety of cutting tools, which makes them versatile and useful for a wide range of applications.
Dynamic Tool Holders
Unlike static tool holders, dynamic tool holders can rotate or move during operations. This unique feature allows these types of tool holders to handle more complex machining tasks. There are two main types of dynamic tool holders:
Rotary Tool Holder
The rotary tool holder rotates at high speeds much like a drill. It is designed for applications that require rotation like drilling or milling. The rotary tool holder enables the machining center to perform turning and milling operations concurrently.
Live Tool Holder
Live tool holders are driven by the CNC machine's spindle motor, allowing the tool to rotate during the process. This distinctive feature makes it possible to perform turning and milling operations simultaneously, reducing the need for secondary operations and increasing efficiency.
Choosing the Right Tool Holder
There are several factors to consider when choosing a CNC turning tool holder: the tooling size, the toolholder's mounting style, and the compatibility with the machine tool. It's also essential to consider the type of operation, the material being machined, and the desired finish and accuracy levels.
While the different types of tool holders have their advantages and challenges, the key is to select the most suitable one for the operation. A slight mismatch could cause inefficiency and compromise the operation's quality. It's essential to consult with machine tool experts or read manufacturer's documentation to make a well-informed decision.
Use this guide to familiarize yourself with the different types of CNC turning tool holders. Remember, selecting the correct tool holder is a critical step towards achieving precision and enhancing the longevity of your cutting tools in CNC operations. Happy machining!
