High-speed machining

Dynamic balancing is crucial! Hydraulic or heat-shrink toolholders are preferred. Both effectively address the pain points of traditional toolholders under high-speed rotation, such as poor concentricity, reduced clamping force, and chatter: Hydraulic toolholders achieve uniform clamping through hydraulic oil expansion, offering high rigidity and excellent vibration resistance; heat-shrink toolholders achieve tight tool locking through thermal expansion and contraction, resulting in high clamping accuracy, lightweight structure, and excellent dynamic balancing performance. Both types of toolholders prevent tool displacement, workpiece deviation, and tool chipping, extending tool life and ensuring machining accuracy and efficiency under high-speed cutting. They are widely applicable to high-end machining scenarios such as precision molds, aerospace, and automotive parts.

Heavy cutting

Side-locking toolholders or heavy-duty end mill holders are the most suitable! For heavy cutting loads, high cutting forces, and strong torque, side-locking toolholders use side screws to clamp the tool, providing strong clamping force and torsional resistance, making them suitable for large-diameter tools and high-torque scenarios. Heavy-duty end mill holders have thickened inner walls and a special clamping structure, offering high rigidity, stable clamping, and vibration reduction. Both types prevent tool loosening and deformation, ensuring machining accuracy and meeting the demanding requirements of heavy cutting.

Small diameter cutting tools (<3mm)

Worried about tool breakage? Spring collet tool holders offer even clamping and fine-tuning! For machining small-diameter tools, where flexibility, precision, and damage prevention are crucial, spring collet tool holders are the optimal choice. They use an elastic collet to evenly clamp the tool, adapting to various sizes of small-diameter straight shanks, making clamping convenient and tool changing efficient; concentricity can reach within 0.005mm, meeting the needs of precision machining; the clamping force is gentle and does not damage the tool's thin shank, and the lightweight structure reduces tool chatter, ensuring stability and precision in fine machining such as engraving and precision milling.

Five-axis linkage

Five-axis machining requires handling complex angular cutting, high-frequency tool changes, and ultra-high precision. High-precision hydraulic toolholders paired with HSK toolholders are the core choice. HSK toolholders feature dual positioning via a conical surface and end face, offering high rigidity and positioning accuracy, suitable for high-speed, high-load applications. The hydraulic toolholders have a concentricity of ≤0.003mm, excellent vibration resistance, and stable clamping without displacement. This combination can offset angular errors in five-axis machining, suppress chatter, and ensure dimensional accuracy and surface quality for machining complex curved surfaces, making it suitable for high-end manufacturing scenarios such as aerospace and precision mold making.
