《GB/T 5900.4-2022机床主轴端部与卡盘连接尺寸第4部分：圆柱连接》由TC22（全国金属切削机床标准化技术委员会）归口，TC22SC9（全国金属切削机床标准化技术委员会机床附件分会）执行，主管部门为中国机械工业联合会。

Introduction

Analysis of Standard Core Parameters

Marking Range	Number of Threaded Holes	Distribution Circle Diameter(d3)	Tolerance Range(µm)
No. 3	6 Holes	70.6 mm	0/-140
No. 4-28	12 Holes	82.6~647.6 mm	0/-380~0/-2500

Tolerance matching system

Table 2 reveals the key matching indicators: the tolerance band of "positioning diameter d2" gradually expands from 113µm (label 8) to 463.6µm (label 28), and the out-of-tolerance control point lies in the machining accuracy of M series threaded holes.

Comparison of technological evolution

Comparison of multi-connection adaptation index:

▸ Stability performance: Conical connection > Column type > Bayonet type
▸ Disassembly and assembly efficiency: Cam locking > Column type > Bayonet type
▸ Manufacturing difficulty: Column type 60 recycled < Conical connection 95 elite manufacturing

Implementation of recommended plans

When the RSK value of the spindle end is ≥800N·m, it is mandatory to select: Column connection system with number 18+
The periodic clamping force decline does not exceed 0.3% of the process design value
Three typical failure modes: [loosening warning] [thread leakage] [final loosening warning], supporting precision compensation kit standardized adoption process
