Broaching Tools TRIZ Cases

A rotating quill maintains a consistent broach tooth rake angle and forms a chip-deflecting trench for better surface finish and precision.

A hard-metal precise sizing section extends internal helical broach life while preserving defined machining performance and accuracy.

A rotating, self-stable broaching tool cuts helical bore grooves in one pass, improving rifling precision and speed on standard CNC machines.

A mixed fcc-hcp Al-Ti nitride coating with low droplet defects improves wear, heat resistance, and adhesion in stainless steel cutting.

Lateral coolant exits beside the insert support let a broaching holder cool and lubricate internal slot cutting edges more reliably.

A staged high-feed broach layout cuts body length and weight while limiting chip interference to preserve accurate gullet tooth profiles.

Sensor-based compensation enables dry fine machining of crankshaft bearing seats with high surface accuracy and varied bearing geometries.

Mechanical dovetail fastening replaces glue in hard-metal broaches, enabling PVD/CVD coating and segment replacement to extend tool life.

Staggered profile groove machining keeps turbomachine disks stable, preventing deformation while meeting high D/W ratios and tight tolerances.

A pivotable cutting element lets rotary broaching vary crankshaft bearing seat geometry during machining without changing tools.

A movable broaching tool inside the lathe spindle enables continuous hole forming and inner-surface broaching without reclamping, cutting time and dimension errors.

A staged high-feed and low-feed broach layout limits chip interference, improves tooth profile accuracy, and shortens broach length.

Linearly stepped cutting teeth remove weld face allowance in one pass, improving surface finish while avoiding grinding faults and dust.

Sequential pendulum-driven drill segments cut skin and bone with lower axial force, controlled motion, and less local heating.

A sputtered Al-Ti nitride coating limits droplet defects and wear in stainless steel cutting while preserving adhesion and heat resistance.

Alternating first and second groove positions stabilize rotor disk machining, limiting deformation, extending tool life, and holding tight tolerances.

Calculating tool pitch based on part thickness and inclination angle reduces cell deformation in small turbine rotor disks.

A plate-based structure with centering and clamping jaws for precise tool positioning in elongated rotor grooves.

Rounded leading edge on broach teeth prevents lateral displacement, extending service life while maintaining surface finish quality.

Segmented clamping distributes shear stress on fasteners, preventing screw breakage during high-force machining operations.
