The treatment mode of small-sized CNC Milling is small-sized CNC Milling is high spirit, efficient treatment facilities, its treatment form and process capability had had substaintial distinction with common treatment facilities. Above all, its treatment facilities that machines a process to resemble a tradition no longer in that way, employee of operation of need a gleam of is held uninterruptedly accuse a machine tool to come true, the whole workpiece treatment of small-sized CNC Milling is the control in system of CNC numerical control falls to be finished automatically, the machine program that craft reachs to ask the work out is reasonable according to blueprint before the member that machine a person as a gleam of needs to be being machined only and choice machine cutting tool reasonably, corresponding treatment cutting tool changes after completing a process in workpiece next can, can say, the member that the person need not be machined in the whole treatment process of workpiece is held actually charge a machine tool, the treatment process that says it so and traditional treatment pattern had substaintial distinction. More traditional treatment facilities can not compare the treatment precision of small-sized CNC Milling, the reason depends on, its main transfer machinery uses traditional gear gearshift orgnaization to cooperate T guide screw to comprise no longer, however the form of guide screw of ball of high speed of drive of system of instead servo control, do not look down upon this kind of little change, it can bring workpiece to machine the change with simple precision. The fixed position precision of small-sized CNC Milling and repeat fixed position precision to be able to be achieved 0. 01mm less than, can complete the treatment of workpiece high accuracy finally. Nevertheless, the treatment precision of the machine tool and process capability are the one part of hardware only, the treatment precision with final work still is affected by the numerous element such as reason of cutting tool, oneself and treatment craft, we besides oneself of treatment machine tool, the cause that causes workpiece to machine out of tolerance is unified return for objective element, simple for, the oneself that causes workpiece to machine the objective element of out of tolerance to basically craft of error of workpiece internal stress, treatment is caused is out of shape and heat is out of shape the error.
