Features of Cam Automatic Lathe

The cam-type moving lathe is equipped with 5 tools, and the tool holders are No. 1, No. 2, No. 3, No. 4, and No. 5 in order. Each group of tool holders can hold 1-2 tools, and No. 1 and No. 5 are outside turning Diameters 2, 3, 4 are mainly grooving, chamfering, cutting and other processes. 2 tail shafts, 2 drill bits, 1 tap and 1 die can be cut at the same time, and tapping, milling, die, embossing, etc. can be processed at the same time. No manual operation is required, and complex parts can be synchronized to the outer circle, spherical surface, conical surface, arc surface, step, grooving, embossing, drilling, tapping, die, cutting and other processes. The whole process can be completed by one processing. .

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

Automatic feeding: the feeding mechanism automatically feeds the material to the main shaft, and automatically stops and alarms when the material is finished. The processing process does not require manual viewing of the material, achieving a fully automated manufacturing process. One operator can operate multiple machines at the same time.

High production efficiency: The machine tool controls the machining process through cams, and each cam rotation completes a machining process. The cam speed is 1.0-36 revolutions per minute, which can be adjusted according to different processing parts. It can process about 30 parts per minute. Since 5 tools can perform cutting at the same time, the processing efficiency is very high. It is a general CNC lathe and instrument lathe incomparable.

The automatic feeding and automatic walking of cutting tools are controlled by cams. Cam type automatic lathes use two types of cams: one is a cylindrical shape. After processing its end surface into various shapes, the cam is rotated and connected by a transmission link and a rocker arm to convert the rotary motion of the cam into a straight line of the tool post. sports. This cam is called a bowl cam and is mainly used to cut the axial cutting direction of the workpiece. The other is a circular plate shape, the outer circumference is processed into the required shape, and then the rotary motion of the cam is changed into the linear motion of the tool through the transmission rod connected with the tool holder; this cam is mainly used for the diameter of the workpiece To the cutting direction. Combining the left and right and forward and backward movements of these two cams can make the tool move in an inclined or curved direction.
