Congratulations to Shandong Pulisen Group on the successful trial cutting of their new crankshaft outer milling product

The member unit of Shandong Equipment Manufacturing Industry Association, the leading unit in China's equipment manufacturing industry, and Shandong Pulisen Group Company have developed a variety of crankshaft machining machine tools in the past, all of which belong to turning machining machine tools. This research and development of the crankshaft external milling XK4363 × 1500 is the company's first exploration into the field of crankshaft milling.

Compared with crankshaft turning, crankshaft milling has more obvious advantages. Firstly, crankshaft milling is much more efficient than crankshaft turning, and more importantly, crankshaft milling can use round bar blanks to directly mill eccentric connecting rod necks. This is of great significance for manufacturers producing crankshafts in small batches or as individual pieces. Because large batches of crankshaft blanks are often precision forged using molds, while small batches of single piece crankshaft blanks cannot be precision forged using molds. Free forging is difficult, costly, and has poor accuracy. The ability to replace forged parts with round bars not only reduces the cost of raw materials, but also shortens the supply cycle, which is undoubtedly a blessing for the small batch crankshaft industry. The crankshaft milling machine market cannot be underestimated.

The crankshaft machine tool of Plison Group has made a great leap from turning to milling. Firstly, milling consumes much more torque and power than turning. The rigidity of the entire crankshaft milling machine was unknown in the past, such as the bed body, headboard, milling head box, cutterhead, tailstock, lead screw, motor, and a series of specialized and purchased parts that are matched with it. The rigidity must be carefully calculated and a suitable safety factor must be left. Secondly, the process method of eccentric milling, including clamping method, milling parameters, tool arrangement, programming method of eccentric milling, etc., is a completely new exploration, and any slight discomfort may result in complete failure.

The XK4363 × 1500 crankshaft external milling has gone through the entire process of research and development of a new product, including Wuxi user communication, process scheme determination, machine tool scheme determination, product design, production and manufacturing, assembly and debugging, and trial processing.

This new product development, from receiving orders to completing assembly and debugging, and trial cutting, took more than half a year. The user's bar blank was milled in one go, and the accuracy was tested. Whether it was eccentricity or angular phase, it far exceeded the user's requirements, which is a successful trial cutting. Congratulations.
