CNC Router 860×780 SMC 4

Detailed Product Review

The CNC Router 860X780 SMC 4 is a computer-controlled machine tool that offers three-dimensional processing capabilities in industrial automation processes. The machine’s fundamental operating principle involves precise linear movements along the X, Y, and Z axes, interpreted by the SMC4-4-16A16B control unit, to process a specific geometry on a material using a cutting tool (spindle). These linear movements are achieved through precision ball screws (1605 on the X-axis, 2510 on the Y and Z axes) driven by JSS Promertech series stepper motors, and 25mm (X, Y axes) and 20mm (Z axis) linear rail systems. The control unit processes numerical data in G-Code format (such as NC, Txt, Tab, Fan) and sends step signals to the motors. These signals, utilizing microstep technology, enable motors with a standard step angle of 1.8° to move with higher resolution (40000 pulses). This integrated motion control system ensures critical engineering values such as ±0.02 mm positioning accuracy and ±0.01 mm repeatability accuracy, allowing for the processing of complex geometries and fine details with millimeter precision.

The spindle unit is an AREL brand, 2.2 kW air-cooled motor, operating within a speed range of 0-18000 RPM controlled by a Siemens inverter, and it secures tools with an ER20 collet system.

Designed in accordance with Mermak CNC engineering standards, the structural integrity of this model is built upon a heavy-duty, monoblock steel construction body. This rigid structure minimizes vibrations during high-speed processing operations, thereby enhancing machining accuracy and surface quality. The body is coated with oven paint, providing resistance to corrosion and an aesthetic finish. Anti-vibration rubber machine feet contribute to overall system stability by damping external vibrations from the working environment or reducing the transmission of machine-generated vibrations to the floor. In terms of system integration, the Siemens inverter precisely manages the speed and torque control of the spindle motor, while drive protection features such as overcurrent, overvoltage, phase error, and thermal protection guarantee the machine’s safe and long-lasting operation.

The CNC Router 860X780 SMC 4 is optimized for a wide range of industrial applications, including but not limited to wood processing, sign making, shaping composite materials, cutting acrylic, mold manufacturing, the packaging sector, and precision engraving of soft metals. This broad material processing capability is supported by its 2.2 kW spindle power and 0-18000 RPM speed range, enabling adaptation to different material hardnesses and machining strategies.

High-Precision Kinematic System: The CNC Router 860X780 SMC 4 utilizes industrial-grade linear rails with a 25mm diameter on the X and Y axes and a 20mm diameter on the Z axis, integrated with 25mm and 20mm linear carriages, respectively. This system provides high rigidity and linear motion stability with minimal friction. Motion transmission is achieved through precision ball screws: 1605 (16mm diameter, 5mm lead) on the X-axis and 2510 (25mm diameter, 10mm lead) on the Y and Z axes. Ball screws convert rotational motion into linear motion, and their zero-backlash design offers ±0.02 mm positioning accuracy and ±0.01 mm repeatability accuracy. This engineering combination ensures superior precision, especially in applications where complex geometries, fine details, and part consistency in serial production are critical.

Integrated and Controlled Machining Power: The machine is equipped with a 2.2 kW air-cooled AREL brand spindle unit. This spindle is controlled by a Siemens inverter, offering stepless speed adjustment capability within a wide RPM range of 0-18000. This extensive speed range allows for the processing of materials with different physical properties, such as wood, composites, acrylic, and soft metals, using optimal cutting speeds and feed rates.
