CNC Machining

cnc machining is the process by which material is removed from a work piece with Computer Numerical Control (CNC) equipment that cuts away unwanted material. Parts are machined from 3D CAD models, processed by the computer and manufactured using the cnc machine. Metal, plastic, wood and aluminum are all good candidates for CNC machining.Speed – CNC machines can quickly produce parts that would normally take multiple steps to manufactureEfficiency – most CNC machines have an internal quality assurance detector that instantly notifies the operator and pauses production the minute an error occursCost Savings – waste is decreased because the operator can optimize raw material usageFlexibility – once a program has been verified and executed for one production, it can be easily recalled for the next run, as well as provide fast change-oversAutomation – many CNC machines can run unattended during the entire machining cycle, freeing the operator to do other tasksIn the inch mode, the smallest increment is usually 0.0001 inch. In the metric mode, the smallest increment is 0.001 millimeterCNC machining is best used when there is a tight tolerance (+/- 0.005")There are multiple secondary options for finishing, including Nitrided,heat treatment, Chrome plated, Passivation,polishing, powder coating, anodizing and many more.Previous: Sheet Metal FarbricationNext: EDM processing in Lemo
