A kind of anti-burr device of plastic plate processing
Technical field
The utility model relates to milling device technical fields, process anti-burr more particularly, to a kind of plastic plate and fill
It sets.
Background technique
T-slot milling cutter processing is the specific purpose tool for processing T-slot, after straight trough mills out, can once mill out precision and reach requirement
T-slot, milling cutter end sword has a suitable milling angle, and cutter tooth is designed by helical teeth, side set, and milling is steady, Milling Force is small.
The milling cutter that processing T-slot generally uses on plastic plate is two tooth, i.e., only there are two cutter tooth, milling cutter is arranged such
Purpose essentially consist in convenient for chip removal and reduce cost, since the quality of plastics is softer, two cutters tooth can be completed normally to expand
Slot milling, thus two tooth T-slot cutters in field of plastics processing using relatively broad.
However, existing milling cutter often can not be clean by the plastic wire band milling of adhesion in expanding slot process, cause
The reason of this problem, there is two, first is that having certain elasticity since plastic material is softer, so that one when milling cutter leaves groove face
Cutting bits can not be cut off;Second is that since the chip generated in milling process fails to be discharged in time, and then it is secondary into milling cutter and milling
The distance between milling cutter and milling face is caused to increase between bevel.Commonly using in field application manually takes blade to these flash millings
It is handled, not only causes a large amount of artificial waste, it is also possible to since misoperation causes damage and the personnel in milling face
It is injured.
