1. High-strength tungsten steel material, outstanding wear resistance and life
Made of alloy CNC tungsten steel, with a hardness of more than HRC90, high temperature resistance and impact resistance, especially suitable for processing hard materials such as stainless steel and titanium alloy156.
Surface coating treatment further extends the service life, which is 30%-50% higher than the life of ordinary tools79.
2. Anti-seismic design ensures processing stability
The tool bar has a built-in anti-seismic damping structure to effectively reduce processing vibration and achieve a high precision of ±0.005mm, which is particularly suitable for deep holes and parts with large aspect ratio68.
In an actual case, after a certain automotive parts company used it, the processing error of the engine cylinder was reduced by 60%6.
3. Precision processing capabilities cover micro-apertures
Supports 0.5mm-6mm micro-aperture processing, with a minimum processing diameter of 0.5mm, meeting the ultra-fine needs of precision instruments, electronic components, etc.13. Provide customized specifications (such as adjustable length of 100mm-300mm), adapt to different depths and complex structure processing scenarios39.
4. Multi-field adaptability and efficient heat dissipation
Widely used in aerospace, medical equipment, automobile manufacturing and other fields, especially suitable for sterile environments and high-precision scenarios369.
Built-in coolant channel quickly dissipates heat to avoid tool overheating and deformation, ensuring continuous processing stability69.
