Collet Chuck Torque Comparison: Up to 230% More Clamping Force
The clamping force of HER25 collet chuck is larger than normal shrink fit chucks, 4° flat shoulder collet chucks and standard ER collet chucks. Taking HER25 as an example: with a 12mm tool, the clamping force of H.E.R. is 145% larger than the 4° collet chuck, 130% larger than normal shrink fit chuck, and 230% larger than standard ER collet chuck.
Un-Mistakeable H.E.R. Original Design
The special double-length guiding structure [1] with trapezoidal thread [2] delivers a strong torque transmitting power but reduces frictional force during tightening. It also ensures the perfect centering of the nut on the chuck. In addition to high concentricity, high repeatability, and strong clamping force, the short thread design significantly reduces tool holder assembly time.
Stability
Three-point and two-sided clamping: The clamping force is evenly distributed on the cutting tool shank. The clamping force of the collet chuck is evenly distributed on the A and B sides. Single-sided clamping: The clamping force is only distributed on the B side. It’s easy for the tool breaking inside the collet and damaging the entire set of tool holders and collets.
Durable
The steel balls are freely distributed and irregular. Imbalance will be the result under high speed. If either the steel balls or the nut body has higher hardness, prolonged use can cause deformation in either component, resulting in a loss of precision.
FAQ
Product FAQS
What is an HER collet chuck, and how does it differ from a standard ER collet?
Redesigned specifically for shop-floor technicians and unmanned automation, this next-generation collet chuck redefines tool holder standard. With an optimized, hassle-free assembly process, anyone regardless of physical strength or job role and even robotic arms can easily assemble a tool that delivers a powerful 200Nm of clamping torque and a high-precision runout of 5 μm.
The original design of H.E.R. technology features double-length guiding technology, a trapezoidal thread structure, an optimized collet-nut assembly method, and collet zero standoff design deliver significantly higher clamping force and stability than traditional ER collets.
What collets can be used with an HER collet chuck?
The best feature of the HER Collet Chuck is its compatibility with the internationally widely used standard ER collet system. We strongly recommend using our HP class ER collets with a torque wrench.
What types of application is best for H.E.R. collet chuck system?
The H.E.R. collet chuck system is best suited for semi-finishing and finishing operations, and it performs flawlessly in light high-efficiency rough milling strategies. Additionally, it excels in hole-making applications such as drilling and reaming.
