原动机及工作机的影响：
原动机和工作机属于影响减速机承载能力的外部因素，由于载荷的不均匀性，它们会给减速机带来外部附加载荷。
影响摆线针轮减速机原动机的工作特性：
均匀平稳：电动机（如直流电动机）、平稳运行的蒸汽机或燃气机、启动力矩小、启动次数很少。
轻微冲击：蒸汽机、燃气轮机、液压马达或电动机（具有较大的、频繁的启起动转矩）
中等冲击：多缸内燃机
严重冲击：单缸内燃机

转手柄好龙头在转动把手时，龙头与开关之间没有过度的间隙，而且关开轻松无阻，不打滑。可劣质水龙头不仅间隙大，受阻感也大。看检测水龙头主体一般都是黄铜。用黄铜制作的产品电镀质量最能保证，黄铜纯度越高电镀质量越好，表面的电镀层越不易被腐蚀。有些厂家为了降低成本，选用锌合金代替黄铜，虽然国家允许使用锌合金材料代替黄铜，但锌合金电镀质量差，耐腐性不强。一般来说，消费者在选购时可采用估计重量的方法进行鉴别，黄铜较重较硬，锌合金较轻较软。

其次在电极加工过程中，石墨电极加工速度明显快于铜电极。比如采用铣削工艺加工石墨，其加工速度较其它金属加工快2～3倍且不需要额外的人工处理，而铜电极则需要人手挫磨。同样，如果采用高速石墨加工中心制造电极，速度会更快，效率也更高，还不会产生粉尘问题。如果具体比较石墨电极与铜电极石墨电极的铣削时间，石墨较铜电极快67%，在一般情况下的放电加工中，采用石墨电极的加工要比采用铜电极快58%。这样一来，加工时间大幅减少，同时也减少了制造成本。
