    • A method and apparatus for cutting a hard and brittle material using a system for applying vibration in two directions with a strip-shaped flat cutting tool. The material to be cut is caused to make a reciprocating motion of a given stroke length together with a first small-amplitude, low frequency vibration in directions parallel to the reciprocating motion. Concurrently with this, a second small-amplitude vibration is applied also to the material to be cut in directions parallel to the cutting direction of the cutting tool into the material and in synchronism with the first small-amplitude vibration. Meanwhile, cutting pressure is applied to the cutting tool to a desired degree with a cutting fluid containing abrasive grain supplied to the cutting part of the material during the process of cutting.
    • 一种用带状扁平切削工具在两个方向上施加振动的系统来切割硬脆材料的方法和装置。 使待切割的材料与给定的行程长度一起进行往复运动,以及平行于往复运动的方向上的第一小振幅低频振动。 与此同时,第二小振幅振动也施加在与切割工具的切割方向平​​行的材料上切割的材料进入材料并与第一小振幅振动同步。 同时,在切割过程中,切削液在切削工具上施加到所需切削温度,其中切削液含有在切削加工过程中供给切削部分的磨粒。

    • In a multi-wire type cutting method comprising the steps of stretching and winding a continuous fine wire many times around four multi-grooved blocks disposed at the vertexes of a rectangle, bringing the lower horizontal parallel stretching lines of the wire into a pressed contact with an object which is to be processed and made of a hard and brittle material, reciprocating the contacting parts of the wire lines while applying an abrasive grain suspension to the contact parts and thus carrying out a cutting process on the object, an unused portion of the wire is gradually fed to the contact parts while a used portion of the wire is gradually moved away from this contact part during the periodical reciprocating motion of the wire lines; low frequency vibration is applied in the cutting direction either to the wire lines or to the object at the contact parts; and the amplitude of the vibration is arranged to be greater than the degree of deflection of the wire lines which takes place when the wire lines are pressed into contact with the object.
    • 在多线式切割方法中,包括以下步骤:围绕设置在矩形顶点处的四个多槽块多次拉伸和缠绕连续的细丝,使得线的下水平平行拉伸线与 要被加工并由硬脆材料制成的物体,使线的接触部分向着接触部分施加磨粒悬浮液,并且对物体进行切割处理,同时使物体的未使用部分 在线路的周期性往复运动期间,线被逐渐地馈送到接触部分,同时线的使用部分从该接触部分逐渐移开; 在切割方向上将低频振动施加到导线或接触部件处的物体; 并且振动的振幅被设置为大于当线路被压接与物体接触时发生的线路的偏转程度。
