Precision ball screw directly affect the positioning accuracy of CNC machine tools, precision ball screw parameters, which lead error effects on the positioning accuracy of the machine the most obvious. 1/3 ~ 1/2 General set screw in the preliminary design of any 300mm stroke volume variation should be less than the target set position V300p positioning accuracy values ??to determine the accuracy of checking in at the end. Lead screw selection is generally based on the design goals of the highest rapid traverse speed vmax, the maximum speed nmax and motor and screw drive servo motor than i to determine. Generally based on the design of the ball screw rated dynamic load to determine the dimensions of the ball screw. Dynamic load rating refers to a group of the same size ball screw after running a million times, the ball screw (threaded surface or ball) 90% of the non-axial load fatigue stripping injury (pitting) time. Minimum axial load to the rail under the table and workpiece friction effect, calculate the maximum axial load of the machine is the maximum load of ball screw driving force, it is cutting force in the axial direction of the force of the ball screw friction between the rail and the (in this case the common rail friction caused by the table, the workpiece, the total weight of the jig and the cutting force of the three components in the direction perpendicular to the rail. Select screw mounting screw support, including ways and wire special bearing selection bar, ball bearing different ways stiffness screw, rotary precision, critical speed has a great influence, generally based on the length of the screw, rotary precision, stiffness requirements and speed to select a different installation methods. Note the use of the ball screw must have three things: Lubrication: When using a ball screw, must have adequate lubrication ? If insufficient lubrication occurs in contact with the metal, resulting in increased friction and wear, resulting in a shortened life expectancy, and so salty failure · Ball Screw The increased use of lubricating ointment used can be divided into two kinds of lubricants and lubrication of ball screw to join in on the general insurance like. grease with increasing rotation speed can make dynamic friction torque line should be more than 3-5m sharing places better oil lubrication · However, do not forget to use grease also appeared connected to 10m / min instance · Palace on equipment also applies to lower-cost general grease · · To take full advantage of the ball screw function, lubricants 5m / min or so is most appropriate * (Details please install precision ball screw) table of ten, said lubricant supply inspection interval when children and general indicators · supply attached to the screw shaft to wipe off the old Green then be lubricated supply · Anti: Rolling ball screw with the same · When there is foreign substance or water, etc., will increase wear and tear, can sometimes cause damage to the ball screw phone manufacturers, such as mechanical work due to the working environment · Wear chips may be mixed cutting oil · So when possible foreign body into the external muddy ball screw sales to fold cloth (with bellows) City real tube telescopic tube and so on, completely covering the screw shaft · weight bias: when the partial load is also the phenomenon of clusters, the The screw should take affect life and noise, and many feel as uneven operation · If the idling screw assembled along with drinking different degrees, in addition to pay attention to the accuracy of the screw itself is a combination of precision · Most adverse phenomenon produce partial load The ball screw wholesale, Lianzhou ball screw, Korea and Taiwan transmission machinery provided by the Dongguan City, South Korea Taiwan Transmission Machinery Co., Ltd., Dongguan City, South Korea Taiwan Transmission Machinery Co., Ltd.
