FAQ

Q: Q1: Why do ordinary small-hole boring tools easily have dimensional drift and poor batch consistency during batch processing?

A: A1: Old boring heads have structural gaps and play, with insufficient adjustment accuracy for tiny apertures. After long-term cutting, tool body wear leads to increased dimensional deviation, resulting in poor batch consistency and high scrap loss. INBH2084 adopts gap-free fine adjustment structure and high-rigidity tool body, which can effectively avoid dimensional drift, ensure batch processing consistency and reduce scrap rate.

Q: Q2: Why do chatter marks frequently occur and surface finish fail to meet standards during small-diameter deep hole processing? How to solve it?

A: A2: The core reason is insufficient rigidity of small boring bars and loose locking structure, which leads to severe resonance during high-speed cutting and inability to suppress cutting vibration. INBH2084 is equipped with high-rigidity anti-vibration tool body and tight locking structure, which can effectively suppress high-speed cutting resonance, eliminate tool bar vibration, completely solve the problem of chatter marks and ensure that the surface finish of the inner hole meets the standard.

Q: Q3: Ordinary boring tools have a narrow aperture range, and frequent tool changes seriously delay production efficiency. How to optimize?

A: A3: Conventional small-hole boring tools have an extremely narrow single aperture range. Small holes and micro holes need separate tool matching, and repeated disassembly and tool setting take a lot of effective machine tool time. INBH2084 supports a wide aperture range of φ6-φ51mm, no frequent tool change is required, and with a convenient tool adjustment structure, it greatly saves tool change and tool setting time and improves production efficiency.

Q: Q4: Traditional fine boring tools have complicated adjustment, large manual errors, and it is difficult for novices to control precision. What should I do?

A: A4: Old boring heads have no convenient rough adjustment structure, the micro-level fine adjustment steps are complicated, the manual operation error is high, the tool adjustment takes a long time, and it is difficult to stably control the precision tolerance of small and micro apertures. INBH2084 is equipped with dual modes of rough adjustment and fine adjustment, rough adjustment for quick positioning, fine adjustment for precise and smooth operation, even novices can easily control precision, reducing manual errors and tool adjustment time.

Q: Q5: During the processing of slender small deep holes, ordinary boring tools are prone to tool deviation and breakage, and the precision cannot be guaranteed?

A: A5: Ordinary boring tools do not support extended thin tungsten steel boring bars. During long-distance processing, the tool body has insufficient rigidity, which is prone to tool deviation and breakage, and the coaxiality and precision of the inner wall of deep small holes cannot be guaranteed. INBH2084 can be flexibly matched with extended tungsten steel boring bars to enhance the rigidity of long-distance processing, avoid tool deviation and breakage, and ensure the processing precision of deep small holes.

Q: Q6: Ordinary boring tools have incompatible interfaces and cannot adapt to the precision processing of slender small deep holes?

A: A6: Traditional boring tools have messy interface specifications, do not support LBK standard interfaces, and cannot be matched with extended thin tungsten steel boring bars, making it difficult to adapt to slender small deep hole processing scenarios. INBH2084 adopts LBK standard universal interface, which can be flexibly matched with BST series anti-vibration boring bars and extended boring bars, perfectly adapting to the precision processing needs of slender small deep holes.
