Recently, stone coal machine company successfully developed QYJ-36 container loading and unloading cranes, the combination of the aircraft and the trailer can be completed independently 20 and 40 feet of two kinds of container self-loading and unloading transport operations, remote control two-speed operation, easy to operate, Reliable performance, is the terminal, station, warehouse and other containers ideal for lifting equipment, can greatly improve work efficiency and reduce labor intensity. According to R & D personnel of Stone Coal Machine Company, the side loading and unloading crane for the container side lifting mode, the crane can move back and forth, loading and unloading two specifications from the side of the container, and for transport operations. Compared with the domestic similar equipment, this machine has significant advantages. First of all, the machine adopts advanced wireless remote control system, with imported remote control, remote control operation, lifting vision; followed by the machine to retain the manual emergency mode of operation, the use of intelligent Safety protection system, smart lock-related dangerous operation, and installed a key to turn off the switch, high safety performance; and equipped with imported electromagnetic proportional valve and centralized lubrication system, precise positioning control, electric control easy to operate; In addition, Heavy-duty state can achieve two-speed operation, can effectively improve the hoisting efficiency. Crane truck crane is one of the leading products company, now has a straight arm, folding arm two series of more than 40 kinds of models, while constantly developing mobile welding workstations, railway line platform, Crane grabs, ship crane And other special crane, and extended production developed a variety of series of special vehicle products, research and development strong production capacity, product market share steady. The successful development of the side loading and unloading transport crane for container added "new member" to the series of special crane products of the stone coal machine company. To make the product as soon as possible the company's new economic growth point, at present, the aircraft has been sent to Shandong Tai'an marketing.
CNC Turning is namely Lathe machining, Lathe machining is a portion of mechanical processing.
Lathe machining is always a process that turning tools doing turning machining to a rotary workpiece. On CNC lathes, the operators or the engineers also can use drills, reamers, screw taps, threading dies and knurling tools to make relative machining work. CNC turning is usually applied to machining shafts, plates, bushings and all other workpieces which have rotary surfaces, it is a very widely application in practical mechanical manufacturing.
CNC turning can be divided into rough turning and finish turning, rough turning is for the purpose of machining with big cutting depth and big feed rate, to improve the machining efficiency. However, the precision of rough turning can only be grade IT11, the surface finish can only be Ra 20-10um. On the contrary, semi-finish machining and finish machining usually can only apply high speed but small feeding rate and cutting depth. In this condition, the machining accuracy can be up to grade IT10-7, the roughness can be Ra10-0.6um.
