First, the most common machining problems of milling-turning composite of shaft parts:
Long shaft is easy to vibrate the knife, let the knife, straightness / roundness is difficult to guarantee
Slender shaft with long overhang, poor rigidity, cutting vibrations
Poor dimensional consistency, surface vibration patterns
Multi-step, multi-groove, multi-thread complex machining, many processes are prone to error.
Turning, milling, drilling, tapping and slotting are concentrated in one axis.
Multiple clamping leads to poor coaxiality and position.
Deep holes, eccentric holes, cross holes are difficult to process.
Poor chip removal, cooling is not in place, easy to break the knife, size instability
Poor roughness of the inner wall of the hole
Difficulty in one-time forming of high-precision end face, outer circle, taper and arc.
Require high coaxiality, high roundness and high finish.
Ordinary machine tools need to be processed several times, low efficiency
Shaped shaft, complex surface machining, programming and tooling requirements are high.
Difficult to control the surface contour
High risk of tool interference and overcutting
Poor stability and low pass rate in mass production.
Dimensional drift due to thermal deformation and tool wear
Long changeover and debugging time
Second, compound machine tool solution:
High rigidity bed + high power spindle, vibration suppression and long axis accuracy guarantee.
Turning/milling/drilling/tapping/grooving/threading can be completed in one clamping, eliminating repeated clamping errors.
High-pressure internal cooling + efficient chip removal, stable and reliable for deep holes and difficult-to-machine structures.
Closed-loop control of high-precision guideway, screw and optical encoder, stable output with micron-level precision.
Intelligent compensation (temperature, tool wear), higher batch consistency.
Professional process solution + rapid after-sales commissioning, reducing processing difficulty and improving yield rate.
