You Ji YH

The structural strength of the machines and the performance they offer make the YH series extremely effective in the aerospace, automotive, transport, earthmoving, motorbike, marine, moulding, hydraulics and components sectors.

The load-bearing structure is designed and built with a one-piece block of meehanite cast iron, giving the machines exceptional rigidity.

The You Ji YH series is a range of CNC horizontal lathes designed for precision turning, structured around the YH15, YH20 and YH21 models, which cover different sizes and production capacities within the same construction architecture. Moving from the YH15 to the YH20 and YH21, the range allows the choice of machine to be adapted to specific machining needs, while maintaining the design consistency typical of the YH series and the build reliability that characterizes You Ji production. The horizontal structure, common to all three models, ensures stability and precision when turning components of different sizes, making the series a versatile solution for workshops that need multiple configurations of the same type of CNC lathe.
