Research and Development

Based on management philosophy, as a stand-alone machine or as part of a flexible manufacturing system, the versatile design configuration of You Ji’s products would be your best choice in any aspect of industrial application:

  • Decreased gravitational and centrifugal forces maintain zero elliptical motion during cutting giving optimum roundness.
  • Excellent surface contact between work-piece and chuck to ensure higher precision machining on all YV series machines.
  • Easy to loading & unloading for irregular-shaped and heavy-duty work-pieces.
  • Vertical turning lathe occupies less floor-space in setting up.
  • Vertical turning lathe is based on ergonomics designed and simple to link with the automatic production line.

Manufacturing Process

There is no secret for running a manufacturing business. The most important issue is to be aware of the latest industrial information, to collect and analyze information efficiently, and to transform them into the appropriate products at the right time for the right people. As well as to create as much value as possible for the customers, and simultaneously, the development of both parties is continued in the win-win situations.

This is You Ji’s business philosophy since its establishment t in 1977. In practice, the utilization of the high precision manufacturing facilities and the adoption of the strict assembly control with rigorous inspection in the factory always ensures the perfect completion of each machine.

Our goal is always to meet customers’ applications by collaborating and exchanging information with the international manufacturers, and continuously developing and upgrading the techniques and design in production, in order to offer higher quality products and prompt after-sale services. Therefore, the customers are thoroughly satisfied and benefited from its 26 years great experience and the total commitment.
