在机床上有一种部件是由细长长的金属棒制造的。上面是光洁度很高的表面,有的还要带有螺纹。
On machine tools, there is a component made of slender metal rods. Above is a highly polished surface, some even with threads.
一般在机床上面有螺纹的,叫丝杠。
Generally, there are threads on the machine tool, called lead screws.
光杠:使刀架做纵向或横向自动进给。车削一般零件丝杠:车削螺纹用。
Light bar: causes the tool holder to automatically feed vertically or horizontally. Turning general parts screw: used for turning threads.

梯形丝杠带螺纹就是丝杆螺纹是梯形螺纹的丝杠,分公英制两种.梯形丝杠具有传动效率高,定位准确等特点.而且承载力大,并具有自锁功能. 梯形螺纹一般用于传动,往往有较高质量要求。
Trapezoidal screw with thread is a type of screw with trapezoidal thread, divided into two types: metric and English. Trapezoidal screw has high transmission efficiency, accurate positioning, and large bearing capacity, as well as self-locking function Trapezoidal threads are generally used for transmission and often have high quality requirements.
在车削完毕后较好还要进行热处理,然后上专用磨床上去磨。还有一个办法就是铣。有专用的梯形丝杠铣床可以加工。在普通立式数控铣床上,如果配上数控分度头和专用刀具,用上第四轴控制功能也可以铣出来,同理卧式铣床也可以做。不过铣出来还是得继续热处理加磨。不淬火不耐磨,不磨表面质量不高。机床丝杠根据用途及使用要求分为7个等级,即3级,4级,5级,6级,7级,8级,9级,3级精度较高, 依次逐渐减低.8级精度以上丝杠所配螺母精度允许比丝杠低一个精度等级. 3级,4级,5级,6级精度的丝杠检测螺旋线轴向误差, 7级,8级,9级精度的丝杠检测螺距误差和螺距累积误差。
After turning, it is better to undergo heat treatment and then use a dedicated grinding machine to grind. Another method is milling. There is a dedicated trapezoidal screw milling machine that can be processed. On a regular vertical CNC milling machine, if equipped with a CNC indexing head and specialized tools, it can also be milled using the fourth axis control function, similar to a horizontal milling machine. However, the milling process still requires further heat treatment and grinding. No quenching, no wear resistance, and low surface quality without grinding. Machine tool screws are divided into 7 levels based on their purpose and usage requirements, namely 3 levels, 4 levels, 5 levels, 6 levels, 7 levels, 8 levels, 9 levels. The accuracy of level 3 is relatively high, and gradually decreases. The accuracy of nuts equipped with screws above level 8 is allowed to be one accuracy level lower than that of the screw Level 3, 4, 5, and 6 precision screw detection spiral axial error, level 7, 8, and 9 precision screw detection pitch error and cumulative pitch error.
