I work for a linear motion company that sells 12 foot lengths of linear motion track. The track is aprox 1/8" to 3/8" thick depending on the size 1018, 1045 and stainless material. We have the drilling of the mounting holes outsourced to a machine ship but would like to transition to "in house" drilling. The machine shop will generally drill 30 holes at a time and then index, and drill 30 more. Any ideas of what the most economical machine would be for this task as it's primarily going to be used for just holes?
