Due to the high ball screw ball screw rolling friction characteristics and excellent transmission efficiency (η = 90 ~ 95%), drive agile and flexible features, it has favorable conditions for acceleration of. Speed ??There are three ways: (1) increase the lead Pn, this is what we often say that the large lead (or a large lead) ball screw. Pn increases because not conducive to improving the accuracy of electric ball screw lead, and feed system static stiffness decreased rapidly, so only suitable for fast driving less precision positioning applications. (2) taking into account the precision, speed, dynamic characteristics, a modest increase in Pn and n (rpm) and the first few threads. Because by the critical speed Nc constraints, the pursuit of high speed is not desirable. (3) reform and innovation from the product structure and drive, for example: the main driver for change screw nut main drive; change a single drive for dual-drive; hollow screw, nut the diameter of the rolling body weight reduction. (4) made of a hollow ball screw, lead screw implement strong cold from inside. Some companies also configure the bore damping rod, to suppress vibration at high speed. HIWIN company's "Cool Type I" series while also implementing strong cold ball nut. Buy fake ball screw ball screw public cause damage to the machine, you can not start, this is a business loss is very large, then how to identify genuine and fake ball screw? Simple true and false identification ball screw - just means different ways, you see ball screw. See you when planning the device size and space, measuring Rockwell hardness, ball screw specifications. Up to HRC60 .. Also consider to screw load. (You can control the drawing) on ??the drawing Ray research sophisticated transmission equipment brand drawings, please call request. The method described online: Using a dial indicator, at the level of the platform, respectively, at both ends and the center to do testing, if beating within 300 words accuracy within 0.02 in C3, it means that the screw is no problem, you can The next check to see whether your machine coaxial above is not fine. Otherwise, the problem is the screw! Also ask about what you buy is what brand of ball screw screw cap, C3 should be grinding level, you do not buy into the cold-screw, not so high precision cold-rolled ball screw's.
