Introduction of floor type boring mills and horizontal boring and milling machine

The floor milling and boring machine is important to process large and super large parts with various profiles. Its technological feature is that it is equipped with a large floor type platform (the size of the workbench is not limited), which can process super long and super wide parts. Together, it can also be equipped with a rotary workbench, which can be used for rotary indexing and radial linear movement. After indexing, it can complete the multi sequence processing of parts, greatly improving the process range. Now the floor type milling and boring machine is specially equipped with a tilt type adjustable angle workbench, which further broadens the processing range. High power and cutting is a major processing advantage of floor type milling and boring machine. High speed and high precision skill requirements increasingly affect the development of floor type milling and boring machine skills, which is an important means to improve the technological level of floor type milling and boring machine. As a result, floor type milling and boring are changing the single high-power and cutting, and are more integrated into the high-speed and high-precision process skills. At present, the ram type structure has become the primary structure type for high-speed milling and boring. The ram has large section, high rigidity, and good stability for high-speed operation, which is convenient for installing various milling head accessories to achieve high-speed machining.

The traditional horizontal boring and milling machine is mainly suitable for processing various mechanical parts, especially the mechanical transmission box and various curved body parts. Because of the progress of various equipment skills, the requirements for mechanical structure are more and more simplified, and the required transmission parts are less and less, especially the parts used as the transmission box will be less and less. The mechanical transmission is mostly driven directly, and the requirements for the accuracy of transmission parts are very high, which puts forward high requirements for the technological performance of horizontal boring and milling machines. Therefore, as the traditional boring shaft structure, the machining objects are decreasing, and will be replaced by the boring shaft free electric spindle, that is, the high-speed machining center is used to complete the processing of various parts. CNC boring and milling machines are developed towards high-speed machining centers. On the one hand, they have strong process adaptability, on the other hand, they have also improved the performance level and processing accuracy. In the process of improving the scope of processing technology, they need various functional accessories as process guarantees, which can not only boring and milling, but also drilling, tapping, installing CNC swing angle milling head accessories, and processing various curved body parts. Equipped with exchange type worktable to form a flexible machining unit, which can process parts in batches
