Lead screw is a relatively precise component, which is a commonly used transmission component in tool machines and precision machinery. Its main function is to convert torque into axial reciprocating force, while also possessing high accuracy, reversibility, and efficiency. Because screw rods have excellent friction characteristics, they are widely used in different industries, and their value and operation in the industry are also very important. Especially in recent years, the use of screw rods in CNC machine tools has become increasingly important, which has greatly driven the development of CNC machine tools in the entire industry, leading to the promotion and application of screw rods in the entire industry, It has also strengthened the technology in China.

丝杠变形的方法

Method of Eliminating Screw Deformation

1、在卡盘的每只卡爪与工件之间垫入4毫米×10毫米的钢丝，夹入长度为15到20毫米。这样在垫入钢丝后，就可以使工作件与卡爪之间成线接触，从而使工件与卡爪之间可以有稍许相对运动，避免工作件被卡爪卡死，起到方向调节的作用，减少工件的弯曲变形。

1. Insert 4mm between each claw of the chuck and the workpiece × 10mm steel wire with a clip length of 15 to 20 millimeters. After the steel wire is inserted, a linear contact can be formed between the work piece and the claw, allowing for a slight relative movement between the work piece and the claw, avoiding the work piece from being stuck by the claw, playing a directional adjustment role, and reducing the bending deformation of the work piece.

2、将机床尾座改为带弹簧的弹性。弹力大小由顶紧的程度决定，当工作件受切削热产生膨胀而伸长时，推动压缩弹簧作轴后移，避免了丝杠产生弯曲变形，从而保证加工精度。

2. Change the high-quality tail seat of the machine tool to elastic and high-quality with springs. The size of the elastic force is determined by the degree of high-quality top tightening. When the working piece expands and elongates due to cutting heat, it pushes the high-quality compression spring to move the shaft backward, avoiding bending deformation of the lead screw and ensuring machining accuracy.

丝杠具备了比较的摩擦特性，所以在不同行业中的应用都比较广泛，而且在行业中发挥的价值和作业也是非常重要的，尤其是在更近几年的发展中，丝杆在数控机床中的使用越来越重要，还很大程度的带动了机床在整个行业中的数控化发展，导致丝杆在整个工业中也具备了推进和运用，也对国内在技术上进行了壮大。所以丝杆在整个运用中还是非常重要的，不仅可以实践价值和性能的存在，还能根据客户认为正确的方式进行消费，应该根据不同的技术方式进行不同设计，来对消费进行适当的控制，有效的实现消费与工作之间的相互结合。

The screw has excellent friction characteristics, so it is widely used in different industries, and its value and operation in the industry are also very important. Especially in recent years, the use of screw in CNC machine tools has become increasingly important, which has greatly driven the CNC development of machine tools in the entire industry, leading to the promotion and application of screw in the entire industry, It has also strengthened the technology in China. So the screw rod is still very important in the entire application. It can not only practice the existence of value and performance, but also consume according to the correct way that customers think. Different designs should be made according to different technical methods to appropriately control consumption and effectively achieve the combination between consumption and work.
