As the core application field of CNC vertical lathes, the construction machinery industry has the characteristics of "large size, heavy load and high precision" in parts machining. Key parts such as flanges, wheel hubs and crankshafts all need to be efficiently machined by CNC vertical lathes. The application of CNC vertical lathes not only improves the precision of parts machining, but also promotes the upgrading of the production mode in the construction machinery industry.
Taking a German construction machinery enterprise as an example, the enterprise previously used multiple equipment for multi-process machining of flange parts, which required multiple processes such as rough machining by horizontal lathe and finish machining by vertical milling machine. Not only the production cycle was long, but also multiple clamping led to large precision deviation and high scrap rate. After introducing the CK5112 CNC vertical lathe, relying on the equipment's integrated rough-finish machining capability, the workpiece can complete multiple processes such as turning and milling with one clamping, the production cycle is shortened by 30%, and the scrap rate is reduced to below 1%. At the same time, the 5-ton load capacity and 1250mm turning diameter of the CK5112 can easily meet the machining needs of large flanges, with the surface roughness stably at Ra1.6μm, fully meeting the equipment assembly requirements.
In the machining of mining equipment parts, the heavy-duty cutting capacity of CNC vertical lathes is fully reflected. Parts such as wheel hubs and gears of mining machinery are mostly made of high-strength alloy steel, which are difficult to cut and have extremely high requirements on equipment rigidity. With an overall weight of 7.5 tons and a high-rigidity bed structure, the CK5112 can achieve a cutting depth of more than 20mm, and with the strong power of the 22kW main motor, it ensures a stable and efficient cutting process, avoiding tool wear and part precision deviation caused by equipment vibration.
With the development of the construction machinery industry towards large-scale and precision, the application scenarios of CNC vertical lathes are constantly expanding. In the future, CNC vertical lathes equipped with turning-milling compound functions and AI adaptive cutting technology will further meet the machining needs of complex parts and become the core support for high-end manufacturing in the construction machinery industry.
