Precision automatic lathes can be divided into walking type and cutting type

1. Heart to heart machining process: It involves clamping the machining material with a simple clamp, moving the material forward while the tool remains stationary, and machining the part through the linear or swinging motion of the tool.

2. The machining process of walking tool: It is to clamp the workpiece with a simple clamp and machine the workpiece by moving the cutting tool back and forth, left and right.

3. The walking cam automatic lathe is equipped with 5 knives, and the tool holder is arranged in sequence as No.1, No.2, No.3, No.4, and No.5 knives. Each set of tool holders can hold 1-2 knives. No.1 and No.5 are for turning the outer diameter, while No.2, No.3, and No.4 are mainly for cutting grooves, chamfering, cutting, and other processes. Two tail shafts, two drill bits, one tap, and one die can be cut simultaneously, and can also be used for tapping, milling, die pressing, embossing, and other processing. No manual operation is required, and complex parts can be processed synchronously for external circle, spherical surface, conical surface, circular arc surface, step, groove cutting, embossing, drilling, tapping, plate teeth, cutting and other processes. The entire process can be completed in one processing step.

4. High dimensional control accuracy: The spindle accuracy of the machine tool can reach 0.003mm, the slider fine adjustment is controlled by a micrometer, the dimensional control accuracy can reach 0.005mm, and the spindle speed is within 2000-8000RPM. The minimum cutting feed can be controlled to 0.005, and the minimum roughness of the parts (copper parts) can reach Ra0.04-0.08.

5. Automatic feeding: The feeding mechanism automatically feeds the spindle, and when the material is finished, it automatically stops and alarms. The processing process does not require manual inspection, achieving a fully automated production and manufacturing process. One operator can operate multiple machines simultaneously.

6. High production efficiency: This machine tool controls the machining process through a cam, and each rotation of the cam completes one machining process. The cam speed is 1.0-36 revolutions per minute, which can be adjusted according to different machining parts. It can process about 30 parts per minute. Due to the ability of 5 knives to cut at the same time, the machining efficiency is very high, which is incomparable to general CNC computer lathes and instrument lathes.

7. The feeding automation and cutting tool automatic walking are both controlled by cams. The cam type automatic lathe uses two types of cams: one is cylindrical in shape. After processing its end face into various shapes, the cam rotates and is connected to the rocker arm through a transmission link, converting the cam's rotational motion into the tool holder's linear motion. This cam is called a bowl shaped cam, mainly used for cutting the axial cutting direction of machined parts. Another form is a circular plate shape, which is machined into the desired shape on its outer periphery, and then the cam's rotational motion is converted into the tool's linear motion through a transmission rod connected to the tool holder; This cam is mainly used for the radial cutting direction of machined parts. By combining the left and right, as well as the forward and backward movements of these two types of cams, the tool can move in a tilted or curved direction.
