When looking for CNC machines, you are bound to meet these two brand names: Doosan and Okuma. Why so? Because they are not only two of the most popular brands but also two highly reliable brands in the world of CNC machining. These two companies have served several customers all around the world with their top-notch CNC machines, but their targeted customer bases are different, as their products have different kinds of strengths and weaknesses. So, which brand fits your needs? Let’s try to decode that by understanding the key differences between the CNC machines of these two companies.

Key differences between the CNC machines of Doosan and Okuma: 

Here are some of the major differences between the CNC machines of Doosan and Okuma:

  1. Company background and machine lineup:
    • Doosan, which is now known as DN Solutions, is a South Korean CNC machine brand that is well celebrated for its high precision and reliable CNC machines. Their machines are also robust and versatile, helping you to machine different kinds of materials. They focus on continuous research and development, helping them to make and sell advanced CNC machines to their customers. They have a huge lineup of machines which includes lathes, turning centers, vertical and horizontal machining centers, and also modern multi axis CNC machines.
    • Okuma is a Japanese CNC company that has built its reputation all over the world with its high end, precision machining capable CNC machines. They have stood out in the CNC market with their philosophy of making everything in house, which includes their control systems, systems, and all other core parts of their CNC machines. They also have a huge lineup of CNC machines, quite similar to the collection of Doosan.
  2. Control system and programming: 
    • Doosan’s CNC machines mostly feature control systems from FANUC. These control systems are popular in the market, making it easier for the operators to run the machines. Their interface is industry standard and user friendly, which brings down the learning curve for new machines. You can also customize it as per the options made available by FANUC, and they have a lot of customization options and are pretty compatible with different CAM software.
    • Okuma has their own proprietary OSP(Okuma Smart Production) control system. Okuma CNC machines can bring an unparalleled level of integration between the control system, software, and mechanical components due to their philosophy of inhouse production. The OSP control system is well known for different features like thermal friendly concept, collision avoidance system, and open architecture for better customization.
  3. Build quality and mechanical design:
    • Doosan CNC machines have robust designs that help with stability and vibration casting. They have high speed spindle options that have a high speed range up to 15000RPM, with powerful torque and good coolant systems. The robust build of the CNC machines helps the machine to handle aggressive cuts, hard materials, and maintain precision over long periods of time, even during harsh environmental conditions.
    • Okuma CNC machines have high precision machining capabilities, with their thermally stable castings helping in minimal material deformation. They have precision linear and box ways, which are engineered for longevity and accuracy. With the help of high quality materials and advanced manufacturing techniques, Okuma can bring some top notch CNC machines that provide stability, accuracy, and power.
  4. Innovation and automation: 
    • Doosan machines are made with a focus on practical automation solutions that help in productivity and efficiency. Their machines have different automation features like advanced automatic tool changers, robotic loading and unloading, and automatic pallet changers. Their automation features directly help their users increase efficiency and decrease labour costs.
    • Okuma is one of the market leaders when it comes to innovation and automation. Their OSP control system is a cornerstone of the high technological advancements of the brand as it enables seamless automation integration, advanced monitoring solutions, and automated material handling solutions. Okuma has continuously developed different “smart factory” solutions for their CNC machines by incorporating AI, IoT, and data analytics.

Here is a summary of the differences between the features of Doosan and Okuma CNC machines:
