Detailed description of the invention
The following is specific embodiment of the utility model and combine accompanying drawing, the technical solution of the utility model is made further
Description, but this utility model is not limited to these embodiments.
As shown in Figures 1 to 4, this is for the improved cutter arbor matrix of depth drill, and matrix includes the connecting portion of truncated cone-shaped
100, the front end from connecting portion 100 convexes to form columned installation portion 110 and convexes to form from connecting portion 100 rear end
Knife bar portion 120.
Preferably, the outer surface of columned installation portion 110 offers the installed surface 111 tangent with installation portion 110,
Facilitate this utility model to be installed on equipment, improve the steadiness that this utility model is installed.
Further, the end face installed offers and sequentially passes through installation portion 110, connecting portion 100 and knife bar portion 120
Cooling duct, wherein, cooling duct includes main channel 200 and two subaisles 210 all communicated with main channel 200, this
During utility model work, coolant by main channel 200 and can be derived to drill by two subaisles 210, so that
The cutting edge of drill both sides can be cooled down by coolant respectively, it is to avoid the cutting edge of drill front end occurs that temperature is too high existing
The generation of elephant, improves the service life of drill.
Further, the diameter of above-mentioned main channel 200 is more than the diameter of subaisle 210, thus the cooling in main channel 200
