深入探究1985年数控车床的更多细节More detective work on the 1985 cnc lathe
➀ 文章深入分析了1985年Denford Starturn数控车床的安全联锁系统，揭示了继电器、逻辑IC等组件的电压规格问题及工厂接线错误；
➁ 意外发现包括RS Components仍提供40年前原装连接器，以及因工厂装配错误导致速度控制电位器反向工作的设计缺陷；
➂ 解析了该设备的迭代设计（如外置步进驱动器改造），并指出PCB上强电与逻辑电压线路混杂带来的安全隐患。
➀ The article details an investigation into the safety interlock system of a 1985 Denford Starturn CNC lathe, revealing factory wiring errors and voltage rating issues in components like relays and logic ICs;
➀ Unexpected discoveries include the availability of original 40-year-old connectors from RS Components and a reversed speed control potentiometer due to incorrect factory assembly;
➂ The machine's design evolution is analyzed, highlighting ad-hoc modifications (e.g., external stepper drivers) and safety concerns with mixed mains/logic voltage traces on the PCB.
