Introduction to the heart-type and knife-type automatic lathe

1. The heart-shaped processing process: the workpiece is clamped by the clamp, the material moves forward, and the tool does not move, and the part is processed by the linear motion or the rocking motion of the cutter.

2. The cutting process: the workpiece is clamped by a simple clamp, and the workpiece is machined by moving the front and rear of the turning tool.

3, the knife-type cam automatic lathe is equipped with 5 knives, the knife holder in the order of No. 1, No. 2, No. 3, No. 4, No. 5 knife, each set of tool holder can hold 1 to 2 knives, No. 1 and 5 The number is the outer diameter of the turning, and the 2, 3, and 4 are mainly the steps of cutting, chamfering, cutting, and the like. Two tail shafts, two drills, one tap and one die are simultaneously cut, and simultaneous tapping, milling, die, embossing, etc. can be performed. No need for manual operation, complex parts can simultaneously carry out the process of outer circle, spherical surface, conical surface, circular surface, step, cutting groove, embossing, drilling, tapping, die, cutting, etc. .

4, high dimensional control accuracy: machine tool spindle accuracy of up to 0.003MM, slider fine-tuning controlled by a micrometer, size control accuracy of up to 0.005MM, spindle speed of 2000 ~ 8000RPM. The minimum cutting amount can be controlled to 0.005, and the roughness of the parts (copper parts) can be as small as RA0.04~0.08.

5. Automatic feeding: The feeding mechanism automatically feeds the spindle, and the automatic parking alarm is completed after the material is finished. The processing process does not require manual inspection, and the fully automated manufacturing process is achieved. The operator can operate multiple machines at the same time.

6. High production efficiency: The machine controls the machining process through the cam, and the machining process is completed every revolution of the cam. The cam speed is 1.0~36 rpm, which can be adjusted according to different machining parts. It can process about 30 parts per minute. Since 5 knives can be cut at the same time, the machining efficiency is very high. It is a general CNC computer lathe and instrument lathe. incomparable. Aluminum plate spot welding machine

7. Feeding automation and automatic cutting of cutting tools are controlled by cams. The cam type automatic lathe uses two types of cams: one of which is in the form of a cylinder, and after processing the end faces into various forms, the cam for the cutter type automatic lathe (bowl/plate), the cam is rotated, and the transmission link and the rocker arm are passed. Connected to change the rotary motion of the cam into a linear motion of the tool holder. This cam is called a bowl cam and is mainly used for cutting the axial direction of the workpiece. The other is a circular plate shape, the outer circumference is processed into a desired shape, and then the rotary motion of the cam is changed into a linear motion of the cutter through a transmission rod connected to the tool holder; the cam is mainly used for the diameter of the workpiece To the cutting direction. By combining the left and right and front and back movements of the two cams, the tool can be tilted or curved.
