摘要： PURPOSE: A cutting bur for easily discharging chips, a manufacturing method thereof and a using method thereof are provided to prevent a chip form being caught by discharging the chip through a cross cut portion in which a flute is cross cut. CONSTITUTION: A method for manufacturing a cutting bur easily discharging chips is as follows. A bur body is manufacture(S100). The bur body is divided into a head portion and a rod portion based on a neck portion(S200). 6 to 8 flutes are formed in the head portion with six-shaft CNC grinder in a screw method(S300). A surface of the head portion where the flute is formed is cross-cut processed to an opposite direction of a flute forming direction. A length of the bur body is 40.00 to 50.00mm. A length of the neck portion is 0.20 to 2.00mm. A length of the head portion is 0.50 to 2.30mm. A length of the rod portion is 2.00 to 4.00mm.
摘要翻译：目的：提供一种用于容易地排屑的切割头，其制造方法及其使用方法，以防止通过切割槽的十字切口部排出芯片而使芯片卡止。构成：用于制造容易放电芯片的切割毛刺的方法如下。制造胴体（S100）。毛坯体基于颈部分为头部和杆部（S200）。螺杆方式用六轴CNC磨床在头部形成6〜8个凹槽（S300）。形成凹槽的头部的表面被横切加工成与凹槽形成方向相反的方向。毛坯的长度为40.00至50.00mm。颈部的长度为0.20〜2.00mm。头部的长度为0.50〜2.30mm。杆部的长度为2.00〜4.00mm。

摘要： PURPOSE: A tungsten carbide alloy for burring is provided to improve wear resistance without degrading brittle in comparison with a tungsten carbide alloy. CONSTITUTION: A tungsten carbide alloy for burring is composed of 5-13 wt% of Co, 87-95 wt% of WC as a mother material. In case, WC is composed of 93.5-94.2 wt% of W and 5.8-6.5 wt% of C. The particle size of the tungsten carbide alloy for burring is 0.4-0.5μm. A 2.5Ø rod is extrusion-molded and sintered to form the tungsten carbide alloy for burring.
摘要翻译：目的：与碳化钨合金相比，提供用于翻边的碳化钨合金以提高耐磨性而不降低脆性。构成：用于毛刺的碳化钨合金由5-13重量％的Co，87-95重量％的WC作为母料组成。在WC为93.5-94.2重量％的W和5.8-6.5重量％的C的情况下，用于翻边的碳化钨合金的粒径为0.4-0.5μm。 2.5mm棒被挤压成型并烧结以形成碳化钨合金用于毛刺。
