The principle of the CNC machine tool is that the machine tool automatically runs after the input processing program.
The machining program of the part includes the path of the tool and the workpiece movement, the start and stop of the spindle, the adjustment of the speed, the cutting amount, the automatic replacement of the tool, and the switch of the coolant, etc., which are very powerful.
Economical CNC lathes are developed from ordinary lathes. There is no difference between drilling on a number lathe and drilling on a normal lathe. The drill is installed on the tailstock of the lathe according to orders, and the holes are drilled by pushing and rotating the tailstock handwheel.
Because the tailstock does not have an automatic feed function, it relies on manual longitudinal feed, which causes the operator's labor intensity and low production efficiency. The depth of the drilled hole is not easy to control.
Using CNC lathes to process this type of batch products. If a lot of manual labor is still required, then it will not show the high degree of automation characteristics of the machine tool to be controlled. Now it is researched to install the drill bit on the tool holder and use the tool holder's automatic indexing and the function of the carriage to automatically drive the tool holder to realize automatic drilling.
