Haas vs DMG Mori – Which one is better?

Haas and DMG Mori, are two brand names that need no introduction to machining enthusiasts or people who use CNC machines. The brands have been ruling this market for several decades now with their high quality but they both have very distinctive features and are good for different genres of businesses. But how are you going to find which one is good for your business? You are going to find that out once you read our article here.

Key differences between Haas and DMG Mori

Here are some of the major differences between Haas and DMG Mori that you need to know

Company Overview:
- Haas was founded and based out of the United States of America. They are known for making cost effective and user friendly CNC machines. They offer several types of machines like horizontal and vertical machining centers, rotatory tables, and CNC lathes. They focus on affordability, ease of use, and simplicity of design.
- DMG Mori is a brand that originated from the merger of DMG of Germany and Mori Seiki of Japan. This brand is known for its high tech CNC machines that lead the market in innovative technologies. They have a wide range of machines like turn-mill centers, 5 axis milling machines, ultrasonic or laser machining, and comprehensive automation.
Build quality:
- Haas CNC machines utilize a cast iron frame with heavy ribbing which helps for vibration damping and brings more stability during the machining process. But they generally have lower mass and rigidity compared to DMG Mori machines. Linear guides are smaller and cast parts are lighter for Haas CNC machines.
- DMG Mori is renowned for its strong build quality and exceptional rigidity. These machines employ mineral castings and high mass frames for superior vibration damping, rigidity, and thermal stability. These machines are designed for demanding, continuous, high precision machining even with heavy metals.
Precision and performance:
- The Haas CNC machines are capable of holding tolerances that are mostly suitable for basic machining applications (e.g., ±0.002” true positions), but they may need slower feeds for tight tolerance work. They are also good for small to medium batches of production while offering a good spindle speed of 12000RPM in some of its high end models.
- DMG Mori excels when it comes to high precision machining environments while offering tolerances up to ±0.00005″. Their machines have high spindle speeds too, which can go up to 20000RPM for some of its high end CNC machines. The superior acceleration helps in efficient machining in a very short period.
Automation and integration:
- Haas offers some basic automation solutions like automatic tool changers, robotic integration, and pallet pools. But most of these features are generally modular and may not be seamlessly integrated like other high end brands.
- DMG Mori leads in the market when it comes to digitalization or automation. They provide turnkey automation solutions, which also include robotic loading and unloading, AGV integration, and flexible manufacturing systems. Advanced digitalization through remote monitoring, CELOS, and predictive maintenance is also available.
