High specific gravity
tungsten alloy dumbbells have good machining characteristics and can produce dumbbell products of various shapes. Because tungsten-nickel-iron high-density alloy has good ductility, it can be machined such as turning, milling, planing, threading and tapping. Its main processing advantages lie in the variety of processing methods and the high processing accuracy. The high specific gravity tungsten alloy can be machined with a precision of +/-0.05mm, and the complex workpieces are processed in the early stage. High specific gravity tungsten alloy dumbbells can also be processed by grinding. The precision of this processing method is higher than that of turning, which can reach +/-0.01mm. The grinding process mainly deals with the surface, chamfer, groove and other parts of the product. The processing of high specific gravity tungsten alloy dumbbells generally has the following situations: (1) Use general machine tools such as turning, milling, planing, drilling and grinding to process counterweights. (2) For counterweights with high precision requirements, it is difficult to ensure high machining accuracy with ordinary machine tools, so precision machine tools are required for processing. (3) In order to automate the processing of counterweights, especially model holes and cavities with complex shapes, it is necessary to use CNC machine tools (such as three-coordinate CNC milling machines, machining centers, CNC grinding machines and other equipment) to process products.
