According to the national industrial development policy, large-scale bearing manufacturing of large-scale wind turbines in new energy wind power projects urgently requires large-scale vertical shaft composite grinding machines. From the trend of machine tool development, high-efficiency composite grinding technology is also an important direction for the development of the machine tool industry.
Hangzhou Machine Co., Ltd. (hereinafter referred to as Hangji), which is engaged in the manufacture of grinding machines, recognized this earlier and organized the backbone of the technical center and the marketing department. It is a key user in the automotive and bearing industries in Zhejiang and Northeast China. Detailed interviews and investigations were conducted. After careful analysis and research, it is concluded that the vertical-axis composite grinding machine is suitable for the grinding of larger-sized workpieces, and the specification positioning is very important. At the same time, the survey also pointed out that the advantage of developing a small vertical shaft composite grinding machine (diameter less than 300mm) is that its potential market demand is large, the market capacity is large, and the small vertical shaft grinding machine is easy to install, easy to operate, small footprint and relatively high relative accuracy. The weak position is that the current domestic gear grinding process is basically processed by the traditional horizontal inner (or outer) end face compound grinding machine. The equipment and process are relatively mature, and it is not mature to break through the traditional market conditions. To this end, Hangji Co., Ltd. plans to develop a large-scale vertical shaft composite grinding as the “key event†for product structure adjustment.
The CNC vertical shaft composite grinding machine is a grinding machine different from the layout structure of the surface grinding machine. It is a brand new machine tool for Hang Machine. Stones from other hills, can learn. After borrowing international design resources, the mid-range MGKF600 CNC high-precision vertical-axis composite grinding machine was born in Hangzhou. The product adopts a gantry structure layout, a single-slide double-head structure, and an automatic exchange wheel library. The rotary table drives the workpiece to rotate, and the carriage drives the grinding head to move left and right along the beam. The two grinding heads on the carriage can move up and down respectively to complete the grinding task under the control of the system. The composite grinding process of the inner, outer and end faces of the part is completed by one clamping, which has the characteristics of high efficiency, high precision and convenient operation. It can be used for machining parts with small aspect ratio such as grinding discs, short shafts and sleeves. It is suitable for precision machining of auto parts, gear reducers, bearings and other industries with many varieties and small batches.
