NBJ16 MICRO BORING SYSTEM

Boring Bar(extension type)

Core advantages of the product

1. Small hole dedicated: The minimum allowable diameter for boring is 6mm, and ordinary large boring heads cannot process small and precise inner holes

2. Ultra high fine-tuning accuracy: 0.01mm diameter adjustment, easy control of hole size tolerance ± 0.005mm

3. Seismic stability: Positioning of the tool holder cone handle and locking of the boring head on all sides, resulting in fewer vibration patterns during deep hole machining

4. Strong universality: universal for machining centers, CNC milling machines, and vertical milling machines, with a set covering the vast majority of precision holes

5. Convenient replacement: Directly replace different tool holders with the same boring head, quickly switch machining aperture

Applicable processing scenarios

1. Precision bearing seat, hydraulic valve hole, mold guide hole

2. Automated fixtures, precision machining of small holes in aluminum alloy/steel parts

3. High tolerance requirements for internal holes of batch parts and processes with a smoothness within Ra0.8

4. Replace floating reamers to solve the problem of difficult adjustment of reamer size

Precautions for use

1. It is recommended to use low speed and small cutting depth (0.03-0.1mm on one side) for precision machining cutting parameters to avoid tool shaking

2. The boring head scale rotates clockwise → the aperture increases, counterclockwise → the aperture decreases

3. When processing deep holes, it is preferred to use an extended tool holder to avoid excessive overhang and insufficient rigidity

4. Regularly clean the internal screw and locking groove of the boring head, and apply a small amount of anti rust lubricating oil
