Operators first create a processing program using dedicated programming software, which includes information such as machining paths and cutting parameters according to the design requirements of the workpiece. Once the program is completed, it is transmitted to the machine's CNC system. The CNC system converts the received program into electrical signals, which drive the servo motors to operate, controlling the movement of the machine's axes. This enables relative motion between the tool and the workpiece, performing chamfering processing along the predetermined trajectory and parameters. During the machining process, sensors continuously monitor the machine's operational status and processing accuracy. If any deviation occurs, the CNC system automatically compensates and adjusts to ensure that the processing accuracy remains within the specified range.

The pneumatic deburring machines can be categorized into handheld and benchtop models based on their pneumatic power systems and operation methods. Handheld pneumatic deburring machines are compact and lightweight, making them easy to carry and use in various work environments; benchtop models are more stationary and suitable for bulk processing in fixed locations such as workshops. Pneumatic deburring machines are mainly composed of pneumatic motors, tool holding devices, pressure regulators, and air hoses. The pneumatic motor serves as the power source, driving its internal blades to rotate via compressed air, providing power to the cutting tools; the tool holding device is used to secure and replace tools; the pressure regulator adjusts the pressure of the compressed air, controlling the speed and torque of the pneumatic motor; and the air hoses are responsible for transmitting the compressed air.

(II) Working Principle

The working principle of the pneumatic chamfering machine is based on the energy conversion of compressed air. Once the compressed air source is connected, the compressed air flows through the air管道 into the pneumatic motor, propelling the internal blades of the motor to rotate at high speed, which in turn drives the tool to rotate. Operators control the contact angle and position of the tool with the workpiece, utilizing the rotational cutting force of the tool to chamfer the edges of the workpiece. During the process, the pressure of the compressed air can be adjusted by the pressure regulator to modify the speed of the pneumatic motor and the cutting force of the tool, accommodating different materials and processing requirements of the workpiece.
