MFR Series Carbide Boring Tool - 0.8-10mm Precision CNC Anti-Vibration Design for Hardened Steel/Titanium/Stainless Steel
1. Core technology highlights
Material and process
Using high-quality tungsten steel alloy or cemented carbide material, the hardness can reach HRA92 or above, and the wear resistance and impact resistance are significantly better than ordinary high-speed steel.
Special surface coating treatment (such as nano blue coating) further reduces the friction coefficient and extends the tool life to 3-5 times that of ordinary tools.
Structural design
Axial groove chip removal design: effectively reduces cutting resistance and improves processing efficiency, especially suitable for deep hole processing.
Anti-vibration tool bar technology: The built-in shock-absorbing structure can reduce the vibration amplitude by 50%, ensuring that the aperture tolerance is controlled within ±0.005mm.
Modular tool head: supports rapid replacement of 1-10mm diameter range, adapting to different working conditions.
2. Typical application scenarios
Precision machinery field
Aerospace: Processing fuel nozzle micropores (minimum aperture 0.8mm).
Medical equipment: Finishing of titanium alloy artificial joint inner holes (surface roughness Ra≤0.4μm).
Complex working conditions challenge
Machining of stainless steel 304 material: cutting speed can reach 120m/min, and chip breaking effect is excellent.
45° blind hole expansion: the taper design of the tool body ensures processing stability and avoids tool tip damage.
3. Market verification data
User feedback
An automotive parts manufacturer uses the MFR3.5 model to process connecting rod oil holes, with a tool life of 1,200 pieces/blade and a cost reduction of 37%.
When processing the M1.6 threaded holes of the mobile phone middle frame in the 3C industry, the yield rate increased from 85% to 99.2%.
Industrial-grade tools designed for 0.8-10mm micro-hole precision machining, made of carbide tungsten steel and modular anti-vibration structure, suitable for high-precision machining scenarios such as aerospace, medical equipment, etc.
