Effect accelerates the flowing velocity toward milling cutter top export direction, further enhances capacity of heat transmission, substantially increase milling cutter
Service life.
The utility model structure when cutter hub 1 and handle of a knife 2 are dismounting, is conveniently replaceable cutter hub 1.
Cutter hub 1 and its spiral coolant flow channel of inside are passed through 3D printer printing shaping (SLM increasing material systems by the utility model
Make technology), handle of a knife 2 is molded by mechanical processing.
For the utility model by 3D printing and mechanical manufacturing technology organic combination, being applied to this field has following advantage：
1. the optimization pair cutter manufacture technique：Due to exploring SLM increases material manufacturing technologies and ripe tool processing technology
Application of composite, the complicated shape based on carbide-tipped milling cutter can be cumbersome using traditional processing method preparation process, and
The waste of material can also be caused.The body portion for possessing intensive flute in carbide-tipped milling cutter is to melt to increase by selective laser
The customization nonstandard product of material manufacture, shank portion are then by the standardized product of mechanical manufacturing technology mass production, entirety
Part realizes mixing manufacture.Shank portion is connected through a screw thread with body portion, when adding man-hour requirement tool changing, only needs to change tool
There are the different cutter hubs of identical threaded connection, shank portion then to reuse, saves material.This composite manufacturing technology is more to manage
The selection thought, simple part only need to process.More complex part then uses increasing material manufacturing.
2. cutter interior spiral coolant flow channel promotes cutting performance and service life：The geometry of cutter interior coolant flow channel is then
There is certain influence to cutter life.The cutter interior coolant flow channel for melting increasing material manufacturing by selective laser has complicated spiral
The capacity of heat transmission in the flow process at the top of coolant liquid to cutter can be improved in shape geometry, the structure, to improve cutter
Service life and cutter running speed.In addition to this, the trend of coolant flow channel and the spiral shape cutter groove of drill bit are mutually parallel, to
The stability for increasing drill core, improves cooling performance.
3. increasing material manufacturing is melted to the molding advantage of cutter in selective laser：By numerically-controlled machine tool and small-sized cutter gently to cut
Mode manufactures cutter hub and there is a problem of that difficulty of processing is high, process-cycle length.SLM increases material manufacturing technologies are melted in selective laser can not only
Cutter hub manufacture efficiency is enough set to get a promotion, additionally it is possible to which solution is placed on various limitation chains in Tool Design, is brought to Tool Design
Higher degree of freedom.Selective laser fusing SLM increases material manufacturing technologies be we can produce dimensions than in the past more smaller knife
Tool, and can construct and process the complex geometric shapes (including internal geometry) that cannot achieve with tradition machinery.Also, laser
Selective melting metal 3D printing equipment, can be same the more money difference cutter hubs produced for customization in a print out task
When print.
4. other than 3 advantages outlined above, increasing material manufacturing is melted in selective laser can also be in the light weight of cutter structure
Change, topological optimization and unattended production etc. bring greatly improvement and progress.
