Machine tools are essential machines for modern industrial production, it plays an important role in the national economy production. The machine tools can be used to produce many machines, to manufacture many high precision parts. It has various kinds, including CNC machine tools, lathes, cutting tools, crankshaft machine tools and so on. From a wide perspective, the purpose of adding counterweights to the machine tools is on the basis of keeping the machine tools stably functioning performance  then further to increase their productivity. Motor and screw rod on the machine's overall performance play the key roles, if the burden of motor and screw rod is too large, then both will produce too much heat, it will increase the machine's vibrations, reduce the precision of products, thus reduce the using life of the machine tools.

 

The vibration of machine tools not only have great influence on products’ quality in the production process, but also will affect the normal running track of the tools so that cause the processing parts does not meet the production requirements. Since tungsten alloy has good machinability, abrasion resistance, high-temperature and high-density characteristics, and therefore the machine tools’ counterweights that produced by tungsten alloy can be well used to offset the weight of the spindle, thereby reducing the burden of motor and screw rod, reducing the eccentric distance so as to ensure the normal operation of the motor and screw rod, so the vibration machine tools will also be reduced.
