問題一：如何實現設備的小型化與快速集成？

Question 1: How to achieve miniaturization and rapid integration of devices?

爭議點：傳統傳動系統占用空間大且組裝復雜

Controversy point: Traditional transmission systems take up a large amount of space and are complex to assemble

解決方案：

Solution:

模塊化設計：

Modular design:

BNK系列采用標準化絲杠軸（直徑范圍6-80mm）

The BNK series adopts standardized screw shafts (diameter range 6-80mm)

預加工軸端接口（支持伺服/步進電機直連）

Pre processed shaft end interface (supporting direct connection of servo/stepper motor)

配套安裝組件（螺母座公差±0.01mm）

Supporting installation components (nut seat tolerance ± 0.01mm)

空間優化：

Space optimization:

比傳統滑動絲杠節省40%安裝空間

Save 40% installation space compared to traditional sliding screws

典型應用案例：

Typical application cases:

CNC工作臺Z軸驅動

CNC worktable Z-axis drive

醫療CT掃描床升降機構

Medical CT scanning bed lifting mechanism

問題二：如何降低系統能耗？

Question 2: How to reduce system energy consumption?

爭議點：傳統絲杠傳動效率低下（＜50%）

Controversy point: Traditional screw drive has low efficiency (<50%)

解決方案：

Solution:

滾動摩擦技術：

Rolling friction technology:

精密鋼球（G10級）循環系統

Precision steel ball (G10 grade) circulation system

摩擦系數降0.003-0.005

The friction coefficient drops to 0.003-0.005

能效數據：

Energy efficiency data:

驅動扭矩僅為滑動絲杠1/3

The driving torque is only one-third of that of the sliding screw

實測功率損耗降低67%

Tested power loss reduced by 67%

問題三：如何實現亞微米級定位？

Question 3: How to achieve sub micron positioning?

爭議點：傳統傳動存在爬行現象

Controversy point: Traditional transmission suffers from crawling phenomenon

解決方案：

Solution:

精密進給技術：

Precision feed technology:

脈沖分辨率0.1μm/step

Pulse resolution 0.1 μ m/step

起動扭矩＜0.05N·m

Starting torque ＜ 0.05N · m

配套方案：

Supporting plan:

建議搭配THK LM導軌（重復定位精度±1μm）

Suggest pairing with THK LM guide rail (repeat positioning accuracy ± 1 μ m)
