With the carbide chip of two-sided four sword.
The further technical solution of the utility model is：The first step is equipped with the first blade fixing threaded hole, the
Two steps are equipped with the second blade fixing threaded hole；First layer cutting plate for milling cutters is fixed on the first blade fixing threaded hole by lock-screw
On, second layer cutting plate for milling cutters is fixed on by lock-screw on the second blade fixing threaded hole.
The further technical solution of the utility model is：The first layer cutting plate for milling cutters, second layer cutting plate for milling cutters wrap
There are two including, the cutting edge of two first layer cutting plate for milling cutters is arranged symmetrically, the cutting edge pair of two second layer cutting plate for milling cutters
Claim arrangement.
The further technical solution of the utility model is：The installation section of handle of a knife is equipped with coaxial handle of a knife limited bayonet and knife
Handle fixing screwed hole.
The further technical solution of the utility model is：Handle of a knife installation screens is additionally provided on the handle of a knife.
Since using the above structure, the trailing arm beam milling arc slot cutter of the utility model compared with prior art, has following
Advantageous effect：
1. cutter loss can be reduced
Since the utility model includes handle of a knife, the working portion of handle of a knife is equipped with first step and second step, first step
On first layer cutting plate for milling cutters is installed, second layer cutting plate for milling cutters is installed on second step.Therefore, the utility model is using double
Layer blade structure, can effectively reduce the load of unit blade, and cutting edge uses symmetric configuration, stress equalization.In use, adopting
After fixing workpiece to be processed with special fixture clamping, by the feeding of lathe, first make first layer cutting plate for milling cutters by the first of workpiece
Layer material cutting 60%, is further continued for feeding, second layer cutting plate for milling cutters starts the first layer clout of cutting workpiece, reaches processing dimension；
Meanwhile first layer cutting plate for milling cutters starts the 60% of the second layer material of cutting workpiece, feeding is kept, until second layer cutting plate for milling cutters
Cut through the second layer material of workpiece.What cutting way processing generated is all 0.2~0.3mm thickness, and length and width are about 3 × 6mm
Iron filings, iron filings are just pulled out away from workpiece in cutter rotary course.Therefore, when the utility model can avoid processing using Steel Plate Guide Drill
The case where the first layered material block under the cutting of appearance blocks cutter and leads to tool damage reduces so as to reduce cutter loss
Cost of charp tool expense in work pieces process.
2. reducing the Meteorological to equipment, processing efficiency is promoted
Since the utility model can be installed and used on normal horizontal miller, without numerically-controlled machine tool, to reduce
Demand to equipment investment improves processing efficiency without processes such as programmings in digital control processing.
3. can ensure that the cutter stability in heavily loaded cutting process
Since the handle of a knife installation section of the utility model is equipped with coaxial handle of a knife limited bayonet and handle of a knife fixing screwed hole, peace
It is using groove positioning plus bolt fastening when dress, it can be ensured that the stability of cutter in heavily loaded cutting process.
4. the utilization rate of blade can be effectively improved
The first layer cutting plate for milling cutters, second layer cutting plate for milling cutters of the utility model are all made of the carbide cutter tool of two-sided four sword
Piece, the blade can effectively improve the utilization rate of blade due to having the characteristics that two-sided four sword.
5. applied widely
Since the handle of a knife installation section of the utility model is equipped with coaxial handle of a knife limited bayonet and handle of a knife fixing screwed hole,
Screw hole mounting means is mountable to various horizontal universal milling machine, and the scope of application is wider.
In the following, making in conjunction with the accompanying drawings and embodiments to the technical characteristic of the trailing arm beam milling arc slot cutter of the utility model further
Explanation.
