Description
Technical Field
The utility model relates to the technical field of cutters, specifically be a cutter of finish machining minor diameter screw nut lane.
Background
The cutter is a tool used for cutting in mechanical manufacturing, also called a cutting tool, and most of the tools in the lead screw nut processing industry at present are used for grinding and finish machining a ball path of a lead screw nut by using a grinding machine, so that the processing time is long, and the processing efficiency is low.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a cutter of finish machining minor diameter screw nut lane can replace the grinding machine processing with the cutter arbor instead of grinding with the car, improves machining efficiency.
In order to achieve the above purpose, the utility model discloses a following technical scheme realizes: the cutter for finely machining the small-diameter lead screw nut ball channel comprises a cutter bar and a blade, wherein a cutter groove is formed in the outer surface of the cutter bar, a threaded hole is formed in the bottom surface of the cutter groove, a pressing plate is fixedly mounted in the cutter groove through the threaded hole, and the blade is fixedly mounted in the cutter groove through the pressing plate.
Further, the cutter bar is processed by adopting an alloy and tool steel butt welding mode.
Further, the blade is a PCBN full-veneered blade.
Further, the design of the position of the tool groove requires calculating the helix angle of the thread to determine the axial rake angle of the tool groove.
Compared with the prior art, this cutter of finish machining minor diameter screw nut lane possesses following beneficial effect:
this cutter of finish machining minor diameter screw nut lane is through setting up cutter arbor and blade, and PCBN blade is chooseed for use to the blade, can process out the profile of lane through programming in minor diameter nut course of working, realizes replacing the mill with the car, reduces the time of processing, has improved screw nut's machining efficiency.
