1、丝杠螺母的选材：45 钢丝杠和 40Cr 钢丝杠调质的热处理工艺 调质是淬火加高温回火的双重热处理， 其目的是使工件具有良好的综合机械性能。调质钢丝杠有碳素调质钢和合金调质钢二大类，不管是碳钢还是合金钢，其含 碳量控制比较严格。梯形丝杠原材料是通过模具拉光到所需要的中径尺寸，二次冷拉形成表面硬度(0.5 毫米深)达(18°-21°)。

1. Material selection for lead screw nuts: The heat treatment process of quenching and tempering 45 steel wire and 40Cr steel wire is a dual heat treatment of quenching and high-temperature tempering, with the aim of ensuring that the workpiece has good comprehensive mechanical properties. There are two main types of quenched and tempered steel wire rods: carbon quenched and tempered steel and alloy quenched and tempered steel. Whether it is carbon steel or alloy steel, the carbon content control is relatively strict. The raw material of the trapezoidal screw is drawn to the required pitch diameter size through a mold, and the surface hardness (0.5 millimeters deep) is formed by secondary cold drawing, reaching (18 ° -21 °). 

2、丝杠和螺母的公差配合,YF45Mnv钢是85Kgf/mm(785N/mm）强度级别的一切削非调质钢，其抗拉强度，疲劳性能，耐磨性能均优于传统常用的45调质钢及40Cr钢。钛浩产品选用YF45Mnv钢，也可选用45#调质钢及40Cr钢。

2. The tolerance fit of the screw and nut, YF45Mnv steel is a non quenched and tempered steel with a strength level of 85Kgf/mm (785N/mm). Its tensile strength, fatigue performance, and wear resistance are superior to the traditional commonly used 45 quenched and tempered steel and 40Cr steel. Titanium Hao products can use YF45Mnv steel, as well as 45 # quenched and tempered steel and 40Cr steel.

螺母材质选用，螺母材质传统选用：锡青铜6-6-3及锡锌青铜5-5-5。钛浩产品选用铝锡青铜ZCUA110Fe3，HRS~1000，摩擦系数小，无杂音，转动灵活。

Nut material selection, traditional nut materials include tin bronze 6-6-3 and tin zinc bronze 5-5-5. Titanium Hao products use aluminum tin bronze ZCUA110Fe3, HRS~1000, with low friction coefficient, no noise, and flexible rotation.

3、丝杠螺母的润滑：建议对梯型丝杠采用油润滑, 特别是油池润滑或滴油润滑法更有效。油池润滑是适当的方法, 因为这种方法可以满足苛刻的条件, 滴油润滑适合于中低速度和中轻负荷的情况。

3. Lubrication of screw nuts: It is recommended to use oil lubrication for ladder type screws, especially for oil pool lubrication or drip lubrication, which is more effective. Oil pool lubrication is the most appropriate method because it can meet harsh conditions, and drip lubrication is suitable for medium to low speeds and medium to light loads.

梯形丝杠螺母是要求螺纹在运动中作精确移动的关键部件，主要采用合金钢材加工，经过热处理加工，保证其优良的机械性能，在制造过程中，粗精工序分开，有效保证零部件的应力合理分布，关键工序在恒温车间加工，稳定的温度，保证高精度丝杠的全部指标符合有关验收标准。

The trapezoidal screw nut is a key component that requires precise movement of the thread during movement. It is mainly made of high-quality alloy steel and processed through heat treatment to ensure its excellent mechanical properties. During the manufacturing process, the coarse and fine processes are separated to effectively ensure the reasonable distribution of stress in the components. The key process is processed in a constant temperature workshop, with stable temperature to ensure that all indicators of the high-precision screw meet relevant acceptance standards.
