数控钻床和数控铣床是线路板加工中的一种重要设备，该设备价格昂贵，选用数控机床不但对于操作、工艺设定和维护包括对于生产产品的质量都有十分重要。
作为一个工艺人员出于纯的技术及操作方面的考虑，数控机床的选用指标一般从以下方面着手：
1.机床台面的刚性和稳定性：
为了使机床有足够的稳定性、刚性避免振动许多厂商都采用大理石作为床身的材料，某些日本的厂商采用钢材做床身，由于钢材在不同的温度下的变形比大理石大，不稳定，厂商会在软件中采用补偿来消除变形造成的精度损失。目前大多数厂商采用都是天然大理石或人造大理石作为床身，建议采用大理石床身的设备，大理石在平时维护使用洗洁精和水擦洗，不可用酒精。擦完以后用干布擦干，等水分完全挥发后才可以工作。
2.转轴的转速和稳定度：
目前采用的转轴有两种一种为滚动轴承转速***高8万转，另一种为空气轴承转速***高可达12万转。如果是铣床应采用滚动轴承，因其纵向的承载较空气轴承好，其钻夹头也是采购是***的考察范围，有些钻夹头不容易更换维护困难，有些钻夹头磨损很快成了耗材且更换费用很贵，有些则需每日维护浪费时间。转轴的压脚也是另一个，其寿命和设计不合理也会造成很大的麻烦，如轴和压脚之间没有密封造成吸尘器要很大的功率造成吸尘器采购的资金浪费或***吸尘的功率浪费，并有可能产生线路板孔内排屑不良的情况。
