Composition and classification of ball screws

with the nut consisting of a steel ball, pre press plate, reverser, dust collector, etc.
There are too many types of ball screws, here we will list a few common ones
1. Ultra high DN value ball screw: high-speed tool machine, high-speed comprehensive machining center machine;
2. End cap ball screw: fast handling system, general industrial machinery, automation machinery;
3. High speed ball screws: CNC machinery, precision tool machines, industrial machinery, electronic machinery, high-speed machinery;
4. Precision grinding grade ball screws: actuators, valve switch devices, etc. used in CNC machinery, precision tool machines, industrial machinery, electronic machinery, conveying machinery, aerospace industry, and other antennas;
5. Nut rotating (R1) series ball screws: semiconductor machinery, industrial robots, woodworking machines, laser processing machines, conveying devices, etc;
6. Rolling grade ball screw: The advantages of low friction and smooth operation, as well as fast supply and low price;
7. Heavy duty ball screws: fully electric injection molding machines, stamping machines, semiconductor manufacturing equipment, heavy-duty brakes, industrial machinery, forging machinery;
According to the accuracy level, it can be divided into rolling and grinding grade screw rods. Rolling screw rods have relatively lower accuracy and are suitable for situations where accuracy requirements are not very high; And the grinding grade screw has relatively high precision, suitable for occasions with high precision requirements.
According to the ball circulation method in the nut, it can be divided into external circulation, internal circulation, and end cap type. First, let's talk about the bottom cover type. This is an early structure, but its drawbacks are quite obvious. It has now been basically eliminated and is rarely used.
