CNC machines come in different styles, different mechanisms, and different brands. Not all are good for your business, but some of them are great for your business, especially when it comes to the CNC machine’s brand. While machines of some brands don’t work properly and last for very short periods, there are also some brands that have strengthened their brand names by making and supplying strong and robust CNC machines. They have continuously innovated their technologies and features, and always kept customer satisfaction at the top of their priority list. There are two brands that do all these things: DMG Mori and Mighty Viper. These two companies have been hugely successful in the CNC machine making business and are loved by several customers around the world. And in this blog, we will find out which one among these two can be the best for your business?

What are the key differences between the CNC machines of DMG Mori and Mighty Viper? 

Here is a list of some of the key differences between the CNC machines of DMG Mori and Mighty Viper: 

    1. Company background and strengths:  
      • DMG Mori is a brand formed from the merger of DMG and Mori Seiki. Their brand philosophy is mainly concerned with constant innovation, advanced technological solutions, and high precision machining. Their machines are focused on high tolerance industries like medical, aerospace, automotive, and mold making. Their machines are more high end and provide top-notch features that are not easily available in other machines in the market. 
      • Mighty Viper is a USA-based CNC manufacturing company. They focus on making more robust and reliable machines at an affordable price range, and their machines are not as high end as DMG Mori. Their machines are also great for heavy part machining, but can’t match the tech features of DMG Mori. Their machines are well celebrated for being solid and dependable. 

       

    2. Machine portfolio and capabilities: 
      Aspect DMG MoriMighty Viper 
      Product RangeExtensive: turning, milling, multi-axis, laser, ultrasonic, additive, and grinding machines. Focused: vertical/horizontal machining centers, bridge mills, turning centers.
      Axis Configurations3, 4, 5, and multi-axis (up to 6-sided machining).3, 4, and some 5-axis, but less variety in multi-process machines
      Size RangeFrom compact to XXL gantry and portal machinesEmphasis on large-format machines and heavy-duty bridge mills
    3. Technological advancements: 
      • DMG Mori is the market leader when it comes to advanced technologies and features. They have their own proprietary CNC control system known as CELOS, but some of their machines also feature the control systems of FANUC, SIEMENS, and HEIDENHAIN. They have intuitive HMIs and advanced simulation. They have deep automation integration in their modern machines with features like robotic arms, pallet changers, smart factory solutions, digital twinning, and predictive maintenance. 
      • Might Viper CNC machines mostly come with the control systems of SIEMENS, FANUC, and Mitsubishi OEM controls, all of which are common in industry, which makes their machines more user friendly. They don’t have highly advanced tech, but are well known for reliability. Their machines are more focused on heavy cutting and reliability over technology. 
    4. Precision and engineering: 
      • Their machines are made for high precision work, with some machines being able to achieve tight tolerances up to ±0.00005” (1.27 microns). Their machining lineup features some top notch multi axis CNC machines that can do high speed operations. Their machines also feature high speed spindles with some having speeds up to 60,000 RPM, high torque, and advanced cooling features. Their machines are able to deliver a superior surface finish, but their machining complexities might make it hard for newbie operators to handle the machines, and small mistakes might lead to high repair bills.
      • The Mighty Viper CNC machines are highly rigid, with features like thermal symmetry structures in machine columns and bases that are designed to bring better accuracy and minimize thermal deformation. Their machines also have high rigidity bearings for spindles and linear scales for closed loop control. Their machines feature high-speed spindles with good power and torque. Their machines are often considered to be a great choice for heavy parts, as they excel in removing large volumes of materials in every cut. 

Which brand’s product should you choose between DMG Mori and Mighty Viper? 

Here’s a summary of when to choose machines of DMG mori and when to choose machines of Mighty Viper:

Choose DMG Mori CNC machines:

  • If you need top tier precision and sophistication.
  • If you need advanced automation and digital integration. 
  • If you are in high demanding industries or planning to enter one. 

Choose Mighty Viper CNC machines: 

  • If you are new in the business or don’t have any high skilled operators. 
  • If you want quality machines within a limited budget.
  • If you are in heavy duty manufacturing work. 

Conclusion: 

DMG Mori and Might Viper are both great CNC machine brands with superior quality of products. But both of them have very different target customer bases, so you need to figure out whose customer base you fall into.
