Target the future market – Focus on domestic substitution of intelligent tool holders

An intelligent tool holder is a high-end cutting tool accessory integrated with sensors and real-time monitoring functions. It can capture processing status in real time and feed back relevant data synchronously, commonly known as inductive intelligent tool holder. Equipped with an equivalent "brain" compared with standard NC tool holders, it represents cutting-edge global technology. Featuring real-time monitoring & early warning, automatic process optimization and closed-loop data control, it improves machining quality and efficiency, reduces tool change frequency and extends tool service life. Our product is 20%–30% cheaper than similar products like SCHUNK iTENDO² intelligent hydraulic tool holder from Germany. The new inductive intelligent tool holder series launched by Dezhou Guochang Machinery serves as an optimal solution for domestic substitution of intelligent tool holders.

Precision Clamping | Core Features of Hydraulic CNC Tool Holders

Adopting hydraulic expansion clamping structure, hydraulic CNC tool holders deliver high precision and minimal runout, maintaining stable operation even at high speeds. The hydraulic damping effectively reduces vibration to optimize machining performance and cut tool wear. One-touch locking saves time and effort, with uniform clamping force and reliable torque transmission. It is ideal for finish machining of molds and precision parts. Its fixed clamping bore comes with a slightly higher price than standard collet holders.

Hydraulic CNC Tool Holder: High-efficiency Clamping Solution for Precision Machining

Hydraulic CNC tool holders serve as core clamping tools for high-end CNC machining. Based on Pascal's principle, the internal hydraulic oil exerts uniform pressure to deform the thin-walled expansion sleeve at the micron level, enabling gapless full-perimeter clamping of the cutter. It features a radial runout of ≤ 0.003 mm and micron-level repeat positioning accuracy, which is far superior to conventional ER collet holders.

Combining high precision and excellent vibration damping performance, the damping effect of hydraulic oil suppresses cutting vibration, improves workpiece surface finish, and extends tool service life by more than 30%. It is easy to operate. Tools can be replaced quickly with merely a hex wrench without any auxiliary equipment, and the holder is compatible with mainstream interfaces including BT and HSK.

Widely adopted in aerospace, precision mold making, automotive manufacturing and other industries, it is ideal for high-speed finishing, deep cavity machining and processing of difficult-to-cut materials. It is the preferred clamping solution for modern intelligent manufacturing.

Accurate Selection Empowers Machining: High-Precision CNC Tool Holder Selection Guide

With the rapid development of the precision manufacturing industry, high-precision CNC tool holders are key accessories for improving quality and reducing consumption in machine tool processing, making correct selection essential. First, match the spindle model of the machine tool and select standard specifications such as BT, HSK, SK and CAT to ensure accurate interface fitting. Secondly, focus on core precision, and prioritize products with low radial runout, precision grinding and dynamic balance treatment to ensure stable high-speed operation. Choose properly according to working conditions: high-rigidity holders for heavy cutting, and double-sided positioning types for high-speed finish machining. Pay attention to material craftsmanship and durability, and avoid inferior low-precision products. Proper use of premium high-precision tool holders improves workpiece surface finish and dimensional accuracy, cuts tool loss, boosts production efficiency, and consolidates the hardware foundation for high-quality development of intelligent manufacturing.

Analysis of Differences Between BT40 and CAT40 Tool Holder Standards

In CNC machining, both BT40 and CAT40 are No.40 tool holders with 7/24 taper, yet they follow different standards and are not interchangeable. Complying with Japanese MAS403 standard, BT40 features a symmetrical flange and shorter taper section, equipped with M16 metric pull stud. It delivers excellent dynamic balance and low vibration, compatible with Chinese and Asian machine tools, widely used in high-speed precision mold and component machining. CAT40 conforms to American ANSI standard, with asymmetrical flange, deeper key grooves and longer taper section, fitted with imperial pull stud. It ensures sufficient taper contact and superior torque transmission for heavy cutting, prevailing in the North American market and suitable for American machine tools and medium-low speed heavy-duty machining. The two are incompatible in dimensions and accessories. Selection must strictly match the spindle specification to ensure machining accuracy and equipment stable operation.

Detailed Explanation of Seven Common Usage Errors of BT Collet

Unclean installation: Iron filings, oil stains and dust remain on the taper surfaces of tool holder, collet and nut, directly affecting concentricity and machining accuracy.

Collet not fully seated: The collet is not completely locked into the tool holder groove, resulting in loose fitting; tool flying and vibration easily occur at high speed.

Excessive locking force: Tightening the nut with brute force causes collet deformation and out-of-roundness, permanently damaging clamping accuracy.

Excessive tool overhang: Too long tool extension leads to insufficient rigidity, severe machining vibration, poor surface finish and easy tool breakage.

Mixed use of specifications: Randomly mixing standard and non-standard collets of different accuracies causes mismatched bore and shank diameter, resulting in clamping slippage.

Over-speed and over-load operation: Long-term use beyond the rated speed accelerates wear and heat generation, shortening service life.

Continued use of defective collets: Continuing to use worn, rusted, cracked or fatigued collets brings hidden dangers to safety and machining precision.
