Since the domestic non-leak seal technology - mechanical seal applied to industrial pumps, China has a number of pump seals the use of mechanical seals, but the effect is not satisfactory, especially in the coal washing industry, because the pump conveys the liquid solid particles Many operating conditions are poor, mechanical seals are sometimes not as reliable as packing, so the Chinese media pump sealing technology has always been the world packing, sealing effect is far behind and imported pumps.

China University of Mining and the revitalization of national industry as its mission, take the initiative to assume the development of non-leakage pump history mission, based on the international advanced sealing theory and years of practical teaching experience, the use of mechanical seals combined with the deputy impeller seal sealing technology, In 2002, the company cooperated with Shandong Huifeng Machinery Group Co., Ltd. to develop a slurry pump and a circulating pump that did not leak water. To fill the gaps in the domestic leak-free technology.

Today, HSBC Machinery Group Corporation has successively developed a series of non-leaking slurry pumps and circulating water pumps based on this "leak-free sealing technology", which is the only media pump manufacturer in China who bid farewell to the packing seal.

3 axis machining implies that the workpiece remains in the same position while the cutting tool operates along the XYZ plane to trim away material. This is suitable for parts that don`t require a lot of depth and detailing. 3 axis machining is most commonly used to produce mechanical components and is best suited for:
Automatic/interactive operation
Milling slots
Drilling holes
Cutting sharp edges
CNC machining can be broken down into several common types: 3-Axis, 4-Axis, 5-Axis, Turning, and Electrical Discharge Machining (EDM). Although other CNC machining processes exist, such as screw machining, the focus of this CNC machining guide is on the former list.
CNC machining is a broad category for a range of processes. Computer Numerical Control (CNC) is the automated control of machining tools by means of a computer. A CNC machine transforms a piece of material according to instructions from a computer programmed to precise specifications. Although there are manual operated devices for machining, CNC machining provides accuracy and repeatability for the desired result, at a desired price.
