The working principle of a CNC gear hobbing machine is mainly controlled by a computer program, and the operator inputs the parameters of the gear to be machined, such as the number of teeth, module, helix angle, etc,

The computer can automatically calculate the motion path and cutting parameters of the tool. Then, the control system commands the host to cut according to the calculated path and parameters. The advantage of CNC gear hobbing machines lies in their high precision

High efficiency and high adaptability. Due to the entire machining process being controlled by computer programs, various complex gear shapes can be machined with high precision. In addition, its high degree of automation can improve production efficiency in usage scenarios,

CNC gear hobbing machines are widely used in gear machining in industries such as automobiles, aviation, and instruments.

The CNC gear hobbing machine is mainly composed of a host, a control system, a tool drive system, a fixture system, and a cooling system. The host is the main body of the entire equipment, and the scientific design of its structure directly affects the processing efficiency and accuracy of the equipment.

The control system is equivalent to the "brain" of the device, which controls the movement and positioning of the device, as well as various parameters during the processing. The tool drive system is responsible for driving the tool for cutting, while the fixture system is used to fix the workpiece to be machined.

The cooling system is responsible for cooling the cutting tools and workpieces during the machining process to prevent high temperatures from affecting the machining quality.

In addition, the working principle of the gear shaping machine also involves the meshing relationship between the gear shaping cutter and the workpiece, as well as the reciprocating motion of the gear shaping cutter and the rotational motion of the workpiece.

In order to gradually cut to the full tooth depth, the slotting cutter should have a radial feed rate. When the gear cutter moves up and down in a reciprocating motion, the downward direction is the cutting stroke.

In order to prevent the tool from scratching the machined tooth surface and reduce the wear of the tool teeth, the worktable drives the workpiece to exit the cutting area for a certain distance (radial) when the gear cutter moves upwards. When the gear cutter works, the worktable returns to its original position.
