Precision automatic turning or CNC Swiss Turning can be divided into material-walking and tool-walking these two styles.
1.The material-walking turning: Through the simple folder clamping processing materials, materials move forward, and the tool does not move, through the tool of the linear motion or swing movement to process parts.
2.The tool-walking turning : the folder is caught with a simple folder, moving around before and after the tool to move the workpiece.
3.Take the knife-type cam automatic lathe with 5 knives, knife in order for the 1st, 2, 3, 4, 5 knife knife set each knife can be installed 1-2 knife, 1 and 5 No. is the turning diameter, 2,3,4 is mainly slotting, chamfering, cutting and other processes. 2 tail shaft, 2 drill and a tap, a die at the same time cutting, and at the same time tapping, milling, die, embossing and other processing. No manual operation, complex parts can be synchronized to the car cylindrical, spherical, conical surface, circular surface, steps, cutting groove, embossing, drilling, tapping, die, cutting and other processes, the whole process can be completed once automatic turned.
4.The size control accuracy: machine spindle accuracy up to 0.003mm, slider fine-tuning by the micrometer control, size control accuracy of up to 0.005mm, spindle speed within 2000-8000RPM. Cutting the minimum amount of control can be controlled to 0.005, parts of the roughness (copper pieces) minimum up to Ra0.04-0.08.
5.Automatic feeding: feeding body automatically feed to the spindle, finished automatic parking alarm, the process without artificial look at the material, to a comprehensive automated manufacturing process. The operator can operate multiple machines at the same time.
6.High production efficiency: the machine through the cam control process, the cam every turn of a turn to complete a processing process. Cam speed 1.0-36 r / min, can be adjusted according to different processing parts, processing of 30 parts per minute, due to 5 knives at the same time cutting, processing efficiency is very high, is the general CNC computer lathe and instrument lathe incomparable.
7.Feeding automation and cutting tool automatic walking are used to control the cam. Cam-type automatic lathe using two kinds of cam: one for the cylindrical shape, the end of its processing into a variety of forms, so that the knife-type automatic lathe cam (bowl / board) eg:
The cam rotates and is connected by a drive link and rocker arm to change the rotary motion of the cam into a linear motion of the tool holder. This cam is called a bowl-shaped cam, mainly used for cutting the axial direction of the workpiece. The other is a circular plate shape, the outer circumference of the shape into the required processing, and then connected with the knife drive rod, the cam rotation movement into a straight motion of the tool; the cam is mainly used for the diameter of the workpiece To the cutting direction. The left and right of the two cams, before and after the motion synthesis, can make the tool walk in tilt or curve.
