Description

Technical Field

[0001] The utility model belongs to the technical field of drill bit processing, and in particular relates to a micro drill bit production device. Background Art

[0002] With the ultra-large-scale and precision of integrated circuits, more and more requirements are placed on circuit boards, especially with the rapid development of 5G. The proportion of high-density interconnect boards (HDI), flexible circuit boards (FPC) and "IC carrier boards" representing the highest technology of circuit boards in printed boards has increased year by year. This requires that the holes drilled on the board become smaller and smaller, and the density becomes higher and higher. Drills with a diameter of less than 3.175mm are usually called micro drills, or micro drills for short. Micro drills require coolant to lubricate and cool the drills during grinding.

[0003] The coolant pipe of the prior art micro-drill bit production device is installed on the outside of the drill bit fixture, and the coolant is sprayed toward the drill rod in a circumferential manner without any shielding. This causes the coolant to splash everywhere during processing, and the coolant is mixed with acne and debris. The splashing waste liquid splashes on the four walls of the chassis, which is not easy to remove, affecting the processing quality of precision parts and components, and causing difficulties for daily maintenance and cleaning work.

[0007] The bottom of the movable baffle is symmetrically fixedly connected with a spring, and the movable baffle is elastically connected to the sliding plate through the spring.

[0008] The coolant pipe is fixedly connected to the cross bar.
