The pressure sensor surface is subjected to pressure changes and transmits data to the interior of the control module, which can drive the alarm to sound an alarm, thereby reminding the staff to make timely adjustments.

[0014] Compared with the prior art, the present invention provides a CNC horizontal boring and milling machine and a method for using the same, which have the following beneficial effects: 1. When the tool and the spindle are impacted and deviate, the elastic buffer metal sheet will squeeze the sleeve through its own elasticity to buffer and absorb energy, which can improve the stability of the spindle and tool.

[0015] 2. When the spindle offset is too large and affects subsequent processing, the sleeve will be squeezed on the surface of the pressure sensor. The pressure sensor surface is subjected to pressure changes and transmits data to the inside of the control module, which can drive the alarm to sound an alarm and remind the staff to make timely adjustments.

[0016] 3. The main shaft is transmitted through the first gear via the shift block. When the main shaft rotates, the shift block will slide along the inner wall of the strip groove without affecting the transmission effect. When the main shaft collides and deviates, most of the impact force will be transmitted to the sleeve and the first gear, thereby reducing the force on the second gear and the motor and preventing the output shaft of the motor from being damaged.
