Tungsten Carbide Anti-Vibration Boring Tool MPR
1. Material and process advantages
High-strength tungsten steel material
Made of high-quality tungsten steel (hard alloy), with a hardness of HRA92-94, wear resistance and corrosion resistance far exceeding ordinary high-speed steel, which can extend the tool life by 3-5 times.
The overall alloy shank design avoids the problem of easy fracture of the welding structure and improves the seismic performance by 25.
Precision machining process
After vacuum heat treatment and multi-layer nano-coating technology, the cutting resistance is reduced by 15%-20%, which is suitable for the processing of high-hardness materials such as stainless steel and titanium alloy.
2. Functional design advantages
Excellent seismic performance
The unique geometric tip design (such as R0.05-0.2mm edge radius) and damping structure reduce vibration by more than 30%, ensuring that the machining surface roughness is ≤Ra0.4μm.
Support high-speed cutting (recommended speed 8000-12000rpm), meeting the high-precision requirements of aerospace parts.
Flexible adaptability
Covering multiple specifications of head diameter 1.0-6.0mm, shank diameter D4-D8, supporting non-standard customization (such as double-head boring tool 2MTR series), and adapting to CNC lathes, Swiss-type machines and other equipment.
Provide 90 degree/45 degree tool head options to meet the needs of profiling and deep hole processing.
3. Application scenario advantages
Small aperture precision processing
The minimum processing aperture is 1.0mm, and the tolerance is controlled at ±0.005mm, which is particularly suitable for the mass production of micro parts (such as clock gears and medical catheters).
Optimize cutting parameters for materials such as stainless steel and aluminum alloy to reduce the burr rate by more than 90%.
Cross-industry applicability
It has been verified to be applied in high value-added fields such as aerospace (titanium alloy parts), automobile manufacturing (cylinder precision holes), and mold processing (micro insert holes).
4. Operation and maintenance advantages
Ready-to-use design
The blade has a debugging-free installation structure, supports quick tool change, and reduces downtime by 50%.
The toolholder has a standardized interface (such as BT30/40/50), which is compatible with mainstream machine tool brands.
Low maintenance cost
The blades can be replaced individually to avoid overall scrapping; refurbishment services are provided to reduce long-term use costs.
In the vast field of precision machining, the MNR series of small hole boring tools have become invisible craftsmen in the field of micro-aperture machining with their tungsten carbide material and innovative anti-vibration structure24. This tool, designed specifically for CNC machining centers, uses an integral alloy tool bar and optimized geometric blade shape, which can achieve a machining accuracy of ±0.005mm in the ultra-small aperture range of 1.0-6.0mm5. Its R0.05-R0.2mm tool tip arc radius can perfectly adapt to the mirror machining requirements of difficult-to-cut materials such as stainless steel and titanium alloy36. The unique anti-vibration design reduces cutting vibration to less than 30% of traditional tools through the synergy of the internal damping structure of the tool bar and the external coating24, and is available in multiple specifications such as MNR3R0.1L10, MNR5R0.2L22.
