FAQ

  • What about the quality and standard of Chinese machine tools?

    As the machine tool industry standards and quality construction work continues to deepen, the industry in 2020 to make breakthroughs and progress in the upgrading of standards and quality improvement. In January 2020, ISO10791-7:2020 "Test conditions for machining centers - Part7: Accuracy of finished test pieces", an international standard revised by China, was approved by the International Organization for Standardization (ISO) and formally published. In May 2020, the "CNC machine tool interconnection communication protocol standard (NC-Link) and test verification project" organized by the China Machine Tool Industry Association (CMTIA) was accepted by the association. "In September 2020, the China Machine Tool Industry Association group standard "vertical machining center product quality evaluation specification " entered the test verification phase, another four group standards included in the 2020 Association group standards development plan.


  • Why choose our company's products?

        Firstly, most of the basic spare parts of our company's products are produced in China, except for some CNC machines with CNC systems that also need to cooperate with companies in other regions, so we have high efficiency in producing machine tools. 

        Secondly, China has effectively controlled the global epidemic and the import and export has been restored, so we have a strong supply capacity. Also, we accept multiple payment methods, which can make your payment more convenient. Besides, we supply 12 months free warranty for Online Support, Video Technical Support that covers all the series of CNC Forging Machine, CNC Rotary Transfer Machine, CNC Turning Machine, and VMC Machining Center. Engineers Available to paid overseas service Machinery is available as well, which greatly protect your experience.


  • Difference between CNC and VMC
    • CNC has two axes x and z, while VMC has three axes x, y and z.

    • When using CNC machines, we need to change tools manually to fit various workpieces, but VMC machines can change tool heads automatically using their own ATC arm.

    • VMC machines are more accurate than CNC machines and more expensive.

    • CNC mainly used for turning inner and outer diameter whereas VMC mainly used for milling end and milling face.

    • The geometric offsets in the CNC system are the z-axis and x-axis, and the offsets in the VMC machine are z-axis only.

    • The tool is rotating in the VMC, but not in the CNC.

  • Why choose an operating system made in China?

        After more than a decade of technical development, the gap between China's domestic operating system and Siemens or Mitsubishi's operating system has been very small, and the domestic operating system has the ability to provide multiple languages. With the domestic machine, which can make the purchase cost of the machine further reduced, thus making the investment cost greatly reduced.


  • How to choose the right equipment?

    There are two ways to choose the right equipment.


    1. For those who want to replace the machine, the best way is to know what kind of products most customers need and choose the machine suitable for processing this range to ensure the maximum utilization of the machine and maximize the profit.


    2. For users who choose a machine for the first time, they can choose the right range of machines according to their own plans. If you do not have a plan, you can first understand the largest market demand, or supply gap products, so as to choose the right processing machine.


  • Why is the vertical rotary transfer machine more popular with users?

    The vertical rotary transfer machine has the following advantages.

    1、 Good chip discharge ability, chips and scraps will be concentrated in the bottom discharge

    2、 Easy installation and maintenance

    3、 Small footprint compared to horizontal machines

    4、 Convenient for personnel to work

    5、 The cost of the machine is relatively low


  • Why add rotary table 5th axis to CNC milling machine?

    With the addition of a fifth axis, the CNC milling machine becomes a true machining center, allowing the ordinary CNC milling machine to perform more, machining holes in multiple directions.


  • Why Chinese made machines are cheaper?

    1、 China has a rich industrial chain and can produce most of the accessories with low production cost.

    2、 Chinese products pay more attention to the use, the design of the parts are universal, design costs and maintenance difficulties are significantly reduced.

    3、 The relevant core components are localized, plus China's industrial chain is rich, the machine production cost is further reduced.
