产品详情

挤牙丝锥是利用金属塑性变形原理而加工内螺纹的一种新型螺纹刀具，挤牙丝锥挤牙内螺纹是无屑加工工艺，特别适用于强度较低、塑性较好的铜合金和铝合金，也可用于不锈钢和低碳钢等硬度低、塑性大的材料攻丝，寿命长。

丝锥,挤牙丝锥

挤牙丝锥的定义：是一种加工内螺纹的刀具，沿轴向开有沟槽。也叫螺丝攻。丝锥根据其形状分为直槽丝锥, 螺旋槽丝锥和螺尖丝锥。直槽丝锥加工容易，精度略低，产量较大。一般用于普通车床，钻床及攻丝机的螺纹加工用，切削速度较慢。螺旋槽丝锥多用于数控加工中心钻盲孔用，加工速度较快，精度高，排屑较好、对中性好。螺尖丝锥前部有容削槽，用于通孔的加工。工具厂提供的丝锥大都是涂层丝锥，较未涂层丝锥的使用寿命和切削性能都有很大的提高。

挤压丝锥的特点：用挤压丝锥挤出的螺纹表面光洁度高，螺纹的金属纤维不断裂，并在表面形成一层冷硬层，可提高螺纹的强度和耐磨性。它从根本上解决了攻丝的排屑困难问题，因无屑，更有利于螺纹的装配。在电子，塑料行业应用广泛。

挤压丝锥的用途：供加工螺母或其他机件上的普通内螺纹用（即攻丝）.机用丝锥通常是指高速钢磨牙丝锥，适用于在机床上攻丝；手用丝锥是指碳素工具钢或合金工具钢滚牙（或切牙）丝锥，适用于手工攻丝。
