Saw blade for precisely cutting diamond

一种精切金刚石锯片

Abstract

Te utility model discloses a saw blade for precisely cutting a diamond, which is characterized in that a plurality of convex metal pieces are uniformly distributed on the circumference of a metal base body, a cutter head consists of a dispersion block-shaped cutter head and an annular continuous cutter head, wherein the annular continuous cutter head wraps the convex metal pieces, a plurality of V-shaped grooves are uniformly distributed on the annular continuous cutter head, a plurality of fixed holes with irregular shape are uniformly distributed on the middle part of the metal base body, a plurality of convex metal pieces are uniformly distributed on the periphery of the fixed holes, and the dispersion block-shaped cutter head wraps the convex metal pieces; and the thickness of the metal base body is minimum, the thickness of the annular continuous cutter head is larger than that of the metal base body, and the thickness of the dispersion block-shaped cutter head is maximum. During the cutting process, the annular continuous cutter head with large grain diameter cuts the material firstly to generally cut the material, and then the dispersion block-shaped cutter head with large thickness cuts the material to fine grind the cutting cross section, so not only the cutting speed of the saw blade can be ensured, but also the high planeness of the cutting cross section can be ensured. The cutter head is provided with the V-shaped grooves, so the scraping can be successfully discharged from the cutting seam.
本实用新型公开了一种精切金刚石锯片,金属基体的圆周上均布若干个凸出金属片,所述刀头由分散块状刀头和环形连续刀头组成,环形连续刀头包裹在凸出金属片上,环形连续刀头上均匀分布着V型凹槽,金属基体的中部均布若干个形状不规则的固定孔,固定孔的周围均布若干个凸出金属片,分散块状刀头包裹在凸出金属片上;金属基体的厚度最小,环形连续刀头的厚度次之,分散块状刀头的厚度最大。在切割过程中,粒径较大的环形连续刀头先切入材料,进行大体切割,而后厚度稍大的分散块状刀头切入材料对切割截面进行细微磨削,既可保证锯片的切割速度又使得切割截面有较高的平整度。刀头上设有的V型凹槽可以顺利将碎屑排出切缝。
