By adopting technique scheme, utilize the cut surface be obliquely installed, chip is oppositely discharged by the angle that the chip that cut surface produces can press cut surface inclination, avoid the situation that chip is discharged forward, prevent in the gap of talus accumulation and adjacent saw-tooth, prevent chip to be squeezed and be piled up in gap, the chip reducing accumulation, on the impact of cut surface, makes tangent plane more smooth bright and clean.
The utility model is set to further: the cut surface incline direction on described adjacent saw-tooth cutter head is contrary.
By adopting technique scheme, the cut surface incline direction on adjacent saw-tooth cutter head is contrary, and chip first can be made together to discharge from the both sides of saw blade, improves chip removal ability; Secondly, left and right distribution makes the stressed more even of saw blade, and cutting process not easily produces unidirectional inclination.
The utility model is set to further: the rotational plane of the relative saw blade of described cut surface tilts 6 °-8 °.
By adopting technique scheme, when inclined plane angle of inclination is less than 6 °, chip removal effect is also not obvious, and when inclined plane angle of inclination is greater than 8 °, saw blade produces saw blade at cutting process to start to produce small size side-to-side vibrations, the larger danger coefficient that tilts is larger, therefore when inclined plane relative to the rotational plane of saw blade tilt 6 °-8 ° the most suitable.
The utility model is set to further: the cut surface of described each cutter head all crosses the center of gravity/center of blade body.
By adopting technique scheme, cut surface crosses the center of gravity/center of blade body, and cutter head is when extruding cut workpiece, and reaction force is through the center of gravity/center of blade body, the left and right of saw blade in cutting process effectively can be avoided to shake, make cutting process reliably safer.
