The more complex the oil passage of the hydraulic valve block is, the more difficult it is to remove the burr. If the burr is not completely removed, either the hydraulic valve block is scrapped or the whole hydraulic system is paralyzed. AAK is not only 50% more efficient than its peers in processing high-precision and difficult hydraulic valve blocks, but also 100% burr free.
Liam, from Canada, sold a batch of hydraulic shield machines. Because of the burr remained in the hydraulic valve block, it was needed to replace the hydraulic relief valves at a high frequency, which affected the construction. The customer directly complained to the boss and asked the problem to be solved completely within a month, otherwise he would need to charge for the loss of working time. The manufacturer said that because the oil circuit of the hydraulic valve block is complex, it is difficult to ensure 100% burr free. Liam had to find a new manufacturer of hydraulic valve blocks. He kept sourcing for 5 days, but no factory was unwilling to complete the production of 20 hydraulic valve blocks with 100% burr free in 25 days. Liam had a big headache.
Liam got into touch with me directly under the introduction of his friend, and explained the above difficulties he encountered. According to his hydraulic valve block drawing, just from the perspective of processing, it is not difficult, but the burr removal of some holes needs unique skills, which is the reason why other manufacturers are unwilling to produce. After 20 days, 20 hydraulic valve blocks were produced at AAK, and they were finished in 20 days from drawing to shipping.
Three months later, Liam sent an email to say thanks to AAK. The hydraulic shield machine equipped with AAK hydraulic valve blocks, has been very smooth in construction, and no burrs were found. Liam was surprised how AAK completed the hydraulic valve blocks with complex oil circuit free of burr in such a short time? AAK finished the production of hydraulic valve block efficiently, and it is 100% burr free, lies in the following 3 unique skills:
In terms of equipment, the German HECHERT 630 horizontal machining center has 12000 spindles, 60 HSK100 high-speed tools, an XYZ travel of 1050-900-800, a moving speed of 65M, and a tool change time of only 1S. Combined with the Siemens 840D operating system, the machining accuracy can be guaranteed, and the machining efficiency is more than twice that of most machining centers.
Technically, AAK adopt the intelligent grinding to replace the traditional abrasive flow deburring technology. During grinding, the main shaft of the equipment can swing 360 ° at will, and there is no dead angle during grinding. No matter the surface of the hydraulic valve body, or the inner hole, cross hole, blind hole of the hydraulic valve block, as well as the end face and inner and outer contour of the orifice, the burrs can be completely removed.
In terms of detection, the German Karlstorz industrial endoscope is used. The probe can be bent and rotated, and detect the oil passage of the hydraulic valve block for 360 ° without dead angle, to ensure that the hydraulic valve block is free of burrs before shipment.
Last week, Liam sent us an inquiry for another hydraulic valve block. He told me privately that the boss now pays more and more attention to him, and gives him more and more business to handle.
AAK hydraulic valve blocks, high efficiency, high accuracy, no burrs, you can give it a small try.
