🔍 Definition of ISO CNC Machine Toolholders

ISO CNC Machine Toolholders are machine tool components that conform to international standards (primarily DIN 69871) and are designed specifically to connect the CNC machine spindle to the tool. Their core function is to act as a "precision link." A pull stud at the top of the shank automatically pulls the tool into the machine spindle's internal taper (the taper matches the toolholder), while the lower portion secures the tool in place via a toolholder. A typical structure consists of four parts:

Pull stud: Provides automatic spindle tensioning;
Tapered shank: Mate with the spindle's internal taper (common taper 7:24);
Flange and V-groove: Provides gripping by a robot for automatic tool changes;
Toolholder: Holds the tool (such as an ER collet).

⚙️ Core Selling Points

High-Speed Stability and Precision

• Dynamic Balance: Up to G2.5, supports ultra-high speeds of 30,000 rpm, reduces centrifugal vibration, and ensures a smooth engraving surface finish.

• Repeatable Clamping Accuracy: ≤ 0.001mm, ensuring consistent machining even after multiple tool changes.

• Low Air Resistance Design: A nut-free design (like the pull-out ISO-VP404) reduces air resistance and the risk of interference during high-speed rotation.

Materials and Durability

• Titanium Alloy: Made of 20CrMnTi alloy with a hardness of 58-60 HRC, it offers both wear resistance and elasticity, extending its service life.

• Anti-Rust Processing: Special surface treatment ensures compatibility with coolant environments and corrosion resistance.

Versatile Adaptability

• Wide Range of Specifications: Available in ISO20/25/30/40 series (the number indicates the taper diameter), with ISO40 being the most widely used.

• Cooling Compatibility: Supports a variety of cooling solutions (such as DIN 69871 AD type with center coolant holes and B type with side flange coolant holes), meeting the heat dissipation requirements of deep-cavity machining.

• Tool Clamping Range: Compatible with ER collet systems (such as ISO25-ER20), with clamping diameters ranging from 3.0mm to 16.0mm.

Automated and Efficient Production

• V-Groove Design: Facilitates robot gripping, enabling unmanned automatic tool changing and improving efficiency.

• Pull-Back Lock: Enhances clamping force (such as ISO-VP404) to prevent tool loosening during high-speed cutting.

Standardization and Compatibility

• International Certification: Certified with the ISO9001 quality management system, it complies with leading global standards such as DIN, ANSI, and JIS/BT.

• Wide Machine Tool Compatibility: Compatible with high-speed precision equipment such as milling machines, small CNC machining centers, and woodworking engraving machines.

💎 Summary

ISO engraving machine toolholders, with their ultra-high speed stability, micron-level precision, and adaptability to multiple scenarios, have become core components for precision machining. They are particularly suitable for applications requiring stringent efficiency and surface quality, such as mold engraving and precision parts machining. Their modular design and compatibility with international standards further reduce equipment maintenance and upgrade costs.
