Mintech MT series heavy-duty high-precision CNC engraving and milling machines feature an integral cast structure design for the machine base and gantry beam, providing excellent structural rigidity and vibration resistance. This ensures stable motion accuracy and long-term reliability during high-speed machining. The integral structure effectively reduces structural deformation, improving the machine's dynamic response and machining stability.

The worktable is precision-ground from natural granite and combined with an aluminum vacuum adsorption platform. Granite possesses excellent flatness, thermal stability, and vibration damping properties, effectively enhancing processing accuracy and equipment stability. The aluminum vacuum adsorption platform allows for multi-zone vacuum control, and with sealing strips, achieves efficient adsorption and fixation, suitable for the stable clamping of various sheet metal workpieces.

The processing area features a fully enclosed waterproof structure design, effectively preventing coolant splashing and protecting critical machine tool components. This structure is particularly suitable for materials requiring water cooling, such as copper, aluminum, engineering plastics, and insulating materials, enabling stable and reliable dry and wet processing environments, and improving surface finish and tool life.

Differences between A series and B series:

• Frame Structure: The B-type machine features a thicker and heavier frame, with a reinforced and optimized gantry beam. Compared to the A-type machine, its structural rigidity is significantly enhanced, better suited for heavy-duty machining scenarios.
• Guide Rail Configuration: The A-type machine uses 30-grade ball bearing guides; the B-type machine upgrades to 35-grade roller guides. Combined with the structural advantages of roller line contact, its load-bearing capacity, rigidity, and motion stability are superior to the ball bearing guides of the A-type machine.
• Z-Axis Slider: The A-type machine uses a 4-slider combination for the Z-axis; the B-type machine upgrades to a 6-slider combination, further improving the Z-axis's load-bearing capacity and motion smoothness, reducing displacement deviation during heavy-duty machining.
• Spindle System: The A-type machine uses a conventional spindle; the B-type machine upgrades to an 11KW BT40 spindle, offering stronger torque, significantly increasing machining speed and depth of cut, further enhancing heavy-duty machining capabilities, and adapting to the needs of machining high-hardness and thick materials.
• Processing performance and applicable scenarios: Both models have the same mechanical precision level. The core differences lie in processing capabilities and applicable materials: The B-type machine has a thicker frame, a 11KW BT40 spindle with higher torque, higher specification guide rails, and more Z-axis sliders, making it more rigid and having more outstanding processing capabilities. It can achieve faster feed speeds and greater depths of cut, making it suitable for high-speed dry cutting of heavy-duty, high-hardness materials such as thick aluminum plates and thick epoxy boards. The A-type machine is more suitable for processing lighter and softer materials such as acrylic, balancing processing efficiency and product appearance, and meeting the needs of medium to light dry cutting.
