In the production of precision equipment components, many manufacturers still outsource lathe and milling machine processing in separate steps. Multiple workpiece transfers and repeated clamping not only lengthen the overall delivery cycle but also easily lead to dimensional and positional tolerance deviations, resulting in insufficient assembly matching and high rework costs. CNC milling-turning composite machining, relying on multi-axis linkage integrated machining technology, can simultaneously complete all processes such as turning, milling, drilling, tapping, grooving, and chamfering in a single clamping, avoiding the precision loss caused by multiple process transfers. It is currently the mainstream and mature solution for non-standard precision parts processing, widely used in many industries such as new energy, precision instruments, power equipment, and explosion-proof equipment.
The advantage of milling-turning composite equipment lies in one-time clamping and forming. Traditional machining requires rough turning on a lathe, followed by secondary positioning on a milling machine, making it difficult to control coaxiality and perpendicularity. Composite machine tools, relying on multi-axis linkage, complete rotation and milling actions simultaneously, enabling integrated processing of parts such as irregular flanges, eccentric shafts, precision joints with flat slots, and complex valve parts. For small, precision workpieces, a Swiss-type milling and turning machine is used, enabling stable machining of slender shafts and miniature threaded components. Tolerances are controllable within ±0.005mm to ±0.03mm, ensuring uniformity in threads, hole diameters, and end face flatness. Customers can directly assemble the products upon receipt, requiring no additional grinding or correction.
Structural strength and precision stability are optimized through process control. The machining process controls cutting speed and feed rate to reduce workpiece machining stress and minimize deformation during later use. For shafts and connecting joints subjected to high-frequency rotation and repeated disassembly/reassembly, threaded areas are reinforced to prevent stripping and chipping. Cutting paths are optimized for grooving and milling to prevent localized thinning that could affect load-bearing capacity. Each product undergoes a full-dimensional inspection before production, and during mass production, samples are inspected every half hour using a complete set of testing equipment including a coordinate measuring machine, micrometer, and thread gauges. Inspection records are kept for each batch, facilitating quality traceability for customers.
Overall, the core advantages of CNC milling and turning machining are integrated molding, high precision, and low rework costs. It eliminates the precision loss caused by multi-stage transfer and positioning, balancing machining efficiency and finished product stability. Compared to parts machined in separate milling and turning processes, it offers superior coaxiality and geometric tolerances.
