Abstract
The utility model is related to a kind of woodworking machinery machining tool, specifically a kind of to be used for carrying out machined hole smoothing, carpenter's smoothing of reaming processing, reamer.Carpenter's smoothing, reamer include bar-shaped matrix and a principal screw groove being opened on matrix, and the cutting edge that spiral groove edge is formed；The cutting edge dorsal part is physically also formed with the auxiliary screw groove that a plurality of parallel width and depth are less than principal screw groove, auxiliary screw groove edge formation wiper edges, the numerical value of wiper edges helical rake angle γ 1 is 10 °~20 °, and the numerical value of cutting edge helical rake angle γ 2 is 5 °~15 °.The utility model can be improved smoothing effect, simplify the process of reaming smoothing, improve crudy by the combination of cutting edge and wiper edges while reaming cutting is ensured.
Description
Technical field
The utility model is related to a kind of woodworking machinery machining tool, be specifically it is a kind of be used for carrying out machined hole smoothing,
Carpenter's smoothing of reaming processing, reamer.
Background technology
Drilled using carpenter's auger on woodwork, generally there are two problems：Hole wall burr and aperture are small.Not influence phase
Close assembly work, it is sometimes desirable to flower many artificial removal's burrs or reaming.Common reamer utilizes sharp spiral cutting sword
Aperture is cut, but smoothing effect is not good.Influence hole wall surface quality.
The content of the invention
Technical problem to be solved in the utility model be to provide it is a kind of have while reaming cutting ability is ensured compared with
Carpenter's smoothing of good smoothing effect, reamer.
Carpenter's smoothing of the present utility model, reamer include bar-shaped matrix and a principal screw groove being opened on matrix, with
And the cutting edge of spiral groove edge formation；The cutting edge dorsal part be physically also formed with a plurality of parallel width and depth is small
In the auxiliary screw groove of principal screw groove, auxiliary screw groove edge formation wiper edges, the numerical value of wiper edges helical rake angle γ 1 for-
10 °~-20 °, the numerical value of cutting edge helical rake angle γ 2 is 5 °~15 °.
It is preferred that, the auxiliary screw groove has three.
The utility model can improve smoothing by the combination of cutting edge and wiper edges while reaming cutting is ensured
Effect, simplifies the process of reaming smoothing, improves crudy.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model embodiment；
Fig. 2 is the apex point direction end face mplifying structure schematic diagram of the utility model embodiment.
Embodiment
As illustrated, carpenter's smoothing, reamer include bar-shaped matrix and a principal screw groove 1 being opened on matrix, with
And the cutting edge of spiral groove edge formation；The cutting edge dorsal part to be physically also formed with three parallel width and depth small
In the auxiliary screw groove 2 of principal screw groove, auxiliary screw groove edge formation wiper edges, the numerical value of wiper edges helical rake angle γ 1 is -10 °
~-20 °, hole wall smoothing can be processed；The numerical value of cutting edge helical rake angle γ 2 be 5 °~15 °, cut it is sharp, can reaming add
Work.
Claims (2)
1. a kind of carpenter's smoothing, reamer, including bar-shaped matrix and a principal screw groove being opened on matrix（1）, and spiral
The cutting edge of groove edge formation；It is characterized in that：The cutting edge dorsal part is physically also formed with a plurality of parallel width and depth
Auxiliary screw groove of the degree less than principal screw groove（2）, auxiliary screw groove edge formation wiper edges, the wiper edges helical rake angle γ 1
Numerical value is -10 °~-20 °, and the numerical value of cutting edge helical rake angle γ 2 is 5 °~15 °.
2. carpenter's smoothing according to claim 1, reamer, it is characterized in that：The auxiliary screw groove has three.
