Abstract
The processes of deep hole parts is prone to chip blocking due to its large length-to-diameter-ratios. Aiming at this problem, this paper designs a pulse negative pressure chip removal device based on a negative pressure chip removal system, which realizes the supply of pulsed chip removal fluid, and establishes the pulse fluid mathematical model of the device, and analyzes the effect of pulse supply fluid on the effect of chip removal. The simulation test of its chip removal effect is carried out by the Fluent software, and the results show that the pulsed oil supply device can make the chip produce relaxing combined suction force in the chip drain channel and alleviate the occurrence of chip blocking phenomenon.
