Types of Hydraulic Tool Holders
When it comes to high-precision and stable tool holders, hydraulic tool holders are often the first choice. They are known for their ease of use, requiring only a T-handle wrench to securely lock them. Due to their high precision, convenient operation, and versatile options, hydraulic tool holders are increasingly used across various machining applications. Below are the main types of hydraulic tool holders:
1. Ultra-Slim Type (Fine Tapered Tool Holder)
This type of hydraulic tool holder is ideal for five-axis machining centers, composite machines, and mold processing. Its small external diameter at the end is specifically designed to avoid interference with the workpiece. Given the demands of high-speed machining, it incorporates a high dynamic balance hydraulic structure, enabling a maximum speed of 35,000 RPM. As a result, the ultra-slim hydraulic tool holder is a great option for high-speed machining operations, providing excellent performance and precision.
2. End Face Coolant Delivery Type
This type of hydraulic tool holder can deliver coolant directly from the front end face of the tool holder, making it suitable for machines with internal cooling. The internal structure of hydraulic tool holders, which typically includes oil chambers and other mechanisms, makes it very difficult to create internal coolant holes. However, the end-face coolant delivery hydraulic tool holder overcomes this by featuring a coolant or mist outlet near the cutting edge. This setup enhances tool life by providing effective cooling right where it’s needed, increasing tool longevity during machining.
3. Straight Type (Straight Shank)
Straight type hydraulic tool holders are versatile and can be used in various applications. They allow for longer tool extensions and can be utilized on other tool holders, providing the same convenient operation as a hydraulic tool holder. This type improves the versatility of high-precision hydraulic tool holders and is an optimal solution for preventing interference in tight machining spaces.
4. Micro Machining Specialized Hydraulic Tool Holder
This specialized hydraulic tool holder is designed to meet the requirements of high-precision and stable repeatability for micro machining applications. It ensures both high-speed rotation and fine machining while maintaining the precision needed for delicate workpieces. These hydraulic tool holders are crucial for industries that require intricate and detailed machining, providing exceptional stability and performance in micro-scale operations.
Conclusion
Hydraulic tool holders are an essential component in modern machining. Offering a variety of options suited for different operational needs, from high-speed machining to micro machining. Their ability to provide high precision, stable clamping. And improved tool longevity makes them a preferred choice in industries that demand top-notch performance. Whether it’s for mold processing, high-speed rotations, or ensuring interference-free operations, hydraulic tool holders deliver superior functionality and versatility.
