Turning and milling composite machining is an advanced manufacturing technology that combines two processing methods: turning and milling. By completing multiple processing processes on the same machine tool, high-precision and high-efficiency processing of complex parts can be achieved. It breaks the mode of turning and milling separation in traditional machining, significantly shortens the processing cycle of parts, and improves machining accuracy and surface quality. The core features of turning and milling composite machine tools. The multi-axis linkage machining capability is usually equipped with spindle rotation (turning function) and milling spindle (milling function), and supports 3-axis, 4-axis or even 5-axis linkage, which can process parts with complex curved surfaces, grooves, hole systems and other characteristics. Example: Processing complex structural parts such as impellers and engine receivers in the aerospace field. The process is integrated with one clamping to complete various processes such as turning, milling, drilling, tapping, boring, etc., reducing the positioning errors caused by multiple clamping of workpieces and improving processing consistency. Advantages: Especially suitable for precision parts with high precision requirements
During the processing process, the computer issues instructions to the machine tool through the CNC system, and controls the movement of each part of the machine tool according to a predetermined path. The spindle drives the workpiece to rotate, and the tool feeds along the three directions of X, Y, and Z to achieve cutting and machining of the workpiece. The CNC system ensures the efficiency and accuracy of the processing process by accurately controlling various parameters, such as feed speed, spindle speed, cutting depth, etc. Processing advantages: Compared with horizontal lathes, the axis of the CNC vertical car spindle is vertically arranged, and the workbench surface is in a horizontal plane, so the clamping and alignment of workpieces are more convenient. Strong load-bearing capacity: It can withstand heavier workpieces and is suitable for processing large and heavy parts. When the slewing diameter is met, too heavy workpieces are not easy to clamp in the sleeper car. Using CNC vertical car can solve the above problems. Good accuracy retention: This layout reduces the load on the spindle and bearings, so CNC mounts can maintain working accuracy for a longer period of time. add
It consists of cross beams, columns, workbenches, etc., with a stable structure and can withstand large cutting forces and heavy load processing, suitable for rough processing and finishing of large workpieces. Most columns are symmetrical double column design (or single column + auxiliary support) to ensure the overall rigidity and stability of the machine tool. Large stroke and workbench The workbench has a large size and strong load-bearing capacity (can reach dozens of tons), which is suitable for processing workpieces with larger length, width and height sizes (such as large molds and box parts). The X, Y, and Z axes have a large stroke range (for example, the X axes can reach several meters to tens of meters), meeting the full-size machining needs of complex workpieces. The spindle system has a high spindle power (can reach tens of kilowatts) and a wide speed range (usually 10-6000r/min, and high-speed models can reach more than 10000r/min), which can achieve high-speed cutting or strong cutting. The spindle can be equipped with a variety of accessories (such as milling heads, boring heads, drills, etc.), and expands machining functions (milling, boring
