350M / 350M-L/350MS /3 50MS With Sub-Spindle CNC Slant Bed Lathe For Long Shaft Turning And Milling

350M/350M-L/350MS/350MS With Sub-Spindle CNC Slant Bed Lathe For Long Shaft Turning And Milling integrates 35º stepped bed guide rails (high and low rails), A2-8 high-torque electric spindle, and BMT65 power milling turret, the standard programmable hydraulic center frame, servo tailstock, optional sub-spindle and other functional components have launched a machining solution for slender shafts. Multiple processes such as turning, milling, boring, drilling, tapping, and reaming can be completed in one clamping. It can reduce the number of clampings and improve processing accuracy; shorten the product manufacturing process chain and improve production efficiency.
The 350MS turning-milling center is the ideal turning and milling solution for slender shafts. When the ratio of the length of a shaft workpiece to its diameter is greater than 25 (L/d>25), it is called a slender shaft, such as oil cylinders and piston rods, heavy machinery transmission shafts, screws, etc. During the turning process of such slender shaft parts, due to their poor rigidity, the slender shaft is easily bent and deformed under the action of cutting force, own gravity, rotational centrifugal force, and cutting heat, thus destroying the relative relationship between the tool and the part. The interpolation accuracy of the motion causes the processed slender shaft axis to produce wavy flow, which seriously affects the machining accuracy of the part. At the same time, the bending deformation of the slender shaft will also cause vibration in the process system, seriously affecting the roughness of the parts. At present, domestic and foreign manufacturers usually turn and mill slender shaft parts using long-stroke turning and milling composite centers, and use a hydraulic center frame for supporting processing. After the turning process is completed, they are then ground with a grinder.
