The Haas horizontal mill is a computer-controlled milling machine that operates on a horizontal axis, enabling it to produce parts with high precision and consistency. This machine is a division of Haas Automation, a leading manufacturer of CNC machine.
What measures can be taken to ensure the quality of drilling, which accounts for a large proportion in the processing plant
Drilling is a fundamental method of hole processing, which accounts for a significant proportion in factories. The tools used for drilling are shoulder drills and Fried Dough Twists drills, which can process holes on solid materials.
Due to the high cutting load during drilling, poor tool stiffness, and structural disadvantages of the drill bit.
The following problems often occur during drilling: the drill bit is prone to deviation, causing deviation of the hole axis and producing straightness errors; The aperture is easily enlarged; Rough pore wall; The axial force during drilling is large. So the drill bit
Generally, it can only be used for machining holes with low precision requirements, or as rough machining for holes with high precision requirements. The general dimensional accuracy of drilling is T11~T14, and the surface roughness is Ra60~12.5m.
In order to ensure processing quality, the following measures are adopted in the process:
(1) Before drilling, machine the end face to ensure it is perpendicular to the drill bit and prevent deviation.
(2) When grinding, try to make the two main cutting edges of the drill bit symmetrical, so that the radial cutting force generated by the two cutting edges is consistent.
(3) Using a drill die as a guiding device can reduce the deviation at the beginning of drilling, especially when drilling on inclined or curved surfaces.
