MFG X-70 Heavy-duty CNC High-speed Metal Circular Sawing Machine

Upgraded version with 70 mm sawing capacity, 11 kW powerful drive and Ø285 mm TCT high-precision sawing system

1. Product Overview

The MFG X-70 is a heavy-duty fully automatic CNC metal circular saw specially developed for high-cross-section and high-load metal cutting operations. Equipped with a robust processing width, it can cut round bars and round tubes with a diameter or side length ranging from 10 to 70 mm, as well as angle steel and square tubes from 10 to 50 mm at high speed and high precision. The machine adopts an 11 kW (4-pole) high-power spindle motor as the core, and is standard-fitted with imported Ø285 × 2.0 t mm TCT tungsten carbide saw blades, achieving an extremely narrow kerf and maximum material savings. Combined with the upgraded high-power dual servo drive system, self-developed gear backlash elimination mechanism and fully digital touchscreen PLC control, the X-70 delivers a heavy-duty sawing solution featuring high efficiency and ultra-low material loss for non-ferrous metal processing enterprises.

2. Innovative Structure & Performance Advantages

• High-damping Reinforced Bed & Zero-backlash Power Head: The machine bed is welded from high-quality high-strength materials, featuring outstanding vibration absorption and minimal deformation to guarantee stability during heavy sawing operations. The power head is fitted with an 11 kW (4-pole) high-torque spindle drive motor; its gearbox is integrally cast from special high-strength material. Internally, the transmission gears undergo special heat treatment and precision grinding. Coupled with a self-owned intellectual property gear backlash elimination mechanism, it delivers smooth zero-backlash transmission, maintaining superior sawing accuracy and blade service life under stepless speed regulation from 40 to 160 rpm.
• Upgraded High-power Dual Servo Feeding: It completely abandons traditional body offset design. Precision linear guideway and high-power servo motors are adopted together with high-precision ball screw feeding mode. The saw head is driven by a 3.0 kW servo motor for 45° diagonal cutting. The automatic feeding system is powered by a 1.3 kW servo motor, with a single feeding stroke up to 770 mm, greatly improving the stability and precision of heavy bar feeding.
• Intelligent Fixed-length Cutting & Multi-dimensional Clamping System: The machine is equipped with independent horizontal and vertical combined clamping devices to ensure zero displacement during sawing. Controlled by the GFC (Fixed-Length Feeding) mechanism and PLC digital system, it can automatically cut and separate workpieces of 8–99 mm. The remaining off-cut length is controlled at 70 mm + a (a refers to residual material shorter than one cutting length).
• Industrial Hydraulic Power Unit & Safety Protection: The standalone hydraulic system comes with a 110-liter large-capacity oil tank and a 2.25 kW (4-pole) hydraulic drive motor, stably outputting working pressure of 70 kg/cm² (7 MPa). All actuators adopt first-tier brands. The built-in comprehensive flash alarm system monitors hydraulic pressure, air pressure (working air pressure: 4–6 kg/cm²), cutting fluid status and material shortage in real time. The machine will automatically stop if no material is detected for 3 minutes.
• Eco-friendly Dry-type MQL Cooling & Automatic Chip Removal: Adopts imported dry mist spray cooling system, which sprays micro-quantity environmental cutting oil precisely on both sides of the Ø285 mm saw blade to greatly reduce cutting heat. Matched with timed quantitative guide rail automatic lubrication system, round steel wire brush blade cleaner and screw-type chip conveyor, the whole machine maintains excellent chip removal performance and maintenance efficiency during continuous heavy-duty operation.
