- For external & internal threading.
- For metric, unified, pipe threads.
Product Advantages
High-Precision Thread Profile
Utilizes precision grinding technology to achieve a thread profile angle error of ≤ ±0.5°, ensuring dimensional stability of the thread pitch diameter and making it suitable for high-precision machining applications of grade P6 and above.
Diverse Coating Options
PVD coatings (TiAlN/AlCrN) are ideal for machining stainless steel and titanium alloys; CVD coatings are optimized for high-speed machining of steel components; and CBN/PCD inserts are designed to handle hardened steel and non-ferrous metals.
Optimized Chipbreaker Design
Features specialized chipbreaker geometries tailored to specific thread pitches, effectively controlling chip flow direction and preventing chips from tangling or scratching the finished thread surface.
Multi-Tooth Design
Full-profile multi-tooth inserts enable single-pass thread machining, boosting efficiency by 3 to 5 times and significantly reducing the frequency of tool changes.
Usage Precautions
Proper Tool Setting: The tool tip must be aligned with the workpiece centerline (tolerance ≤ 0.1 mm). The relief angle should be maintained between 0.5° and 1.5° to prevent asymmetrical thread profiles or chatter marks.
Control Cutting Parameters: Select an appropriate surface speed based on the workpiece material (80–150 m/min for steel; 50–90 m/min for stainless steel). The depth of cut should decrease with each pass; the initial depth should be 0.15–0.3 mm, while the final pass should be ≤ 0.05 mm.
Ensure Adequate Cooling: High-pressure internal cooling is recommended. The coolant must be directed precisely to the cutting zone to prevent the formation of built-up edges (BUE), which can compromise the surface quality of the thread profile.
Maintain Clamping Rigidity: The workpiece overhang length should not exceed three times its diameter, and the tool holder extension length should not exceed 1.5 times the tool shank height. This prevents vibration from causing the cutting insert to chip or fracture.
