Seiko developed the cooling structure of the ball screw with a nut

Seiko has developed some of the nut ball screw to set the cooling bodies "cooling ball screw nut." May 2010 began selling in 2012 and strive to achieve 10 billion yen in sales. The company originally produced in the cooling part of the set screw body products. After cooling to achieve nuts, ball screws of machine tools installed can achieve high speed and high precision.

Seiko used to cool the nut through the nut marked with holes, so that the cooling flow through manner. Thus, it can be marked with the screw shaft of hollow holes in the cooling of the "axis of core cooling" means almost the same cooling effect. Set the cooling sector costs, lower cooling nuts, if using nuts cooling, will be able to get the original cost the same cooling effect. In addition, by combining the use of nuts and shaft cooling cooling mode, you can get better cooling effect, and further achieve high speed and high precision equipment, technology.

Nuts through the hole marked with dimensions the same as the original product, so you can replace the existing nut. Just set the cooling pipe connected to the peripheral flange of the nut into the exhaust hole, you can supply the cooling fluid.

Cooling nut, there may have pre-contraction pressure load increased due to the nut, ball screw preload torque side effects such as increased or reduced life. To prevent these side effects, new product changes by parsing the pre-pressure load, using the even cooling nuts, pre-press pre-load will not increase the pressure in the form.
