Ball screw is one of the most important parts in machine tools, which directly affects the function of machine tools. Now it is an era of high efficiency, and there are higher requirements for machine tools. If you want the machine tool to function better, you need a ball screw with better function. How can you advance the function of ball screw?

1.恰當加大螺桿的轉速，導程和螺紋頭數

1. Increase properly the speed, lead and number of threaded heads of the screw

現在常用大導程滾珠絲桿名義直徑與導程的匹配為：40*20，50*25等，其進給速度均可達到60m/min以上。為前進滾珠絲桿的剛度和承載才干，大導程滾珠絲桿一般選用雙頭螺紋，以前進滾珠的有用承載圈數。

Nowadays, the matching of nominal diameter and lead of ball screw with large lead is 40*20, 50*25 and so on. Its feed speed can reach more than 60 m/min. In order to improve the stiffness and carrying capacity of the forward ball screw, the large lead ball screw usually adopts double thread, and the number of useful bearing circles of the forward ball screw.

2.改進結構，前進滾珠運動的流暢性

2. Improving the structure and smoothness of forward ball movement

改進滾珠循環反向設備，優化回珠槽的曲線參數，選用三維造型的滾珠管和回珠器，實在做到沿著內螺紋的導程角方向將滾珠引進螺母體內，使滾珠運動的方向與滾道相切而不是相交。這樣可把沖擊損耗和噪聲減較小。

Improve the reverse equipment of ball circulation, optimize the curve parameters of ball return groove, and select three-dimensional modeling ball tube and ball return device, so that the ball can be introduced into the nut body along the guide angle direction of the internal thread, so that the direction of ball movement is tangent to the raceway rather than intersecting. In this way, the impact loss and noise can be minimized.

3.選用“空心強冷”技術

3. Selection of "Hollow Strong Cooling" Technology

高速滾珠絲桿在運行時由于沖突發作高溫，構成螺桿的熱變形，直接影響高速機床的加工精度。選用“空心強冷”技術，就是將恒溫切削液通入空心絲杠的孔中，對滾珠絲桿進行強制冷卻，堅持滾珠副溫度的穩定。這個辦法是前進中，大型滾珠絲桿高速功用和作業精度的有用途徑。

The thermal deformation of high-speed ball screw, which is caused by high temperature due to conflict, directly affects the processing accuracy of high-speed machine tools. Choosing "hollow strong cooling" technology is to put constant temperature cutting fluid into hollow screw holes, force cooling the ball screw, and adhere to the stability of the temperature of the ball pair. This method is a useful way to advance the high speed function and operation accuracy of large ball screw.

4.滾珠絲桿支撐軸承的選擇

4. Selection of ball screw bearing

關于滾珠絲桿軸承的選擇關重要，它直接影響到雕刻機等機床設備或主軸的壽數和功用。

The selection of ball screw bearings is very important, which directly affects the life and function of machine tools such as engraving machines or spindles.
