- check_circle Heavy-Duty CNC Machined Aluminium: High rigidity and thermal stability prevent frame warping under thermal expansion.
- check_circle Coaxial Air-Assist Laser Head: Integrated brass nozzle blows smoke and flare away, protecting optics and keeping kerf clean.
- check_circle Kinematic 3-Screw Mirror Mounts: Fast optical alignment for 25 mm mirrors with anti-vibration locking screws.
- check_circle Standard Lens Compatibility: Supports 20 mm diameter ZnSe focus lenses with 50.8 mm (2.0") or 63.5 mm (2.5") focal lengths.
- check_circle Multi-Type Rail Fittings: Complete compatibility across A-Type, B-Type, and C-Type X/Y inner and outer mounting profiles.
- check_circle Reduction Pulleys & Steel-Core Belts: 3:1 gear reduction assemblies ensure micro-stepping accuracy and eliminate backlash.
- check_circle Water-Cooled Tube Integration: Designed to pair with 40W, 60W, 80W, 100W, and 150W EFR or RECI CO2 glass laser tubes.
Target Applications & Use Cases
Industrial Applications FitOEM manufacturing and custom building of 1300x900 mm flatbed CO2 laser cutting workstations.
Direct replacement of worn-out, warped, or misaligned mechanical gantries in active manufacturing workshops.
Precision cutting of acrylic letters, point-of-sale displays, and architectural scale models.
High-speed cutting of fabric panels, leather shoe uppers, and decorative craft elements.
Intricate laser fretwork, wood boxes, puzzles, and die-less carton prototyping.
Engineering & Production Benefits
Key Operational AdvantagesRigid aluminium brackets lock optical geometry in place, minimizing beam drift during high-speed raster shifts.
Standardized mounting hole patterns allow rapid installation without custom machining or drilling on site.
Optimized coaxial gas flow blows away charred resin and smoke for clean cuts on clear acrylic and wood.
Standard industrial pitch fits leading Indian and imported linear rails, stepper motors, and controller brands.
Spare Part Overview & Technical Description
High-Precision Mechanical Motion Transmission Kit for 1390 Laser Systems
Engineered for custom laser builds, retrofits, and comprehensive shop-floor overhaul of 1300x900 mm CO2 laser cutting and engraving tables, the 1390A Mechanical Kit delivers rigid gantry alignment and micrometer-level optical accuracy. Fabricated entirely from aerospace-grade extruded and CNC-machined aluminium alloy with protective surface anodization, this hardware suite eliminates structural racking and high-speed motion resonance common in budget sheet-metal brackets.
The kit incorporates a complete laser head assembly with coaxial air-assist nozzle cone, designed to accept 20 mm focal lenses (50.8 mm and 63.5 mm focal lengths) and 25 mm reflection mirrors. Precision kinematic mirror adjustment blocks on the first and second optical points feature fine-pitch thumb screws with lock nuts, enabling operators to achieve razor-sharp beam alignment across the entire 1300x900 mm cutting envelope in minutes rather than hours.
Comprehensive Hardware Configuration & Fitting Types:
- Laser Head Set: Integrated lens tube with adjustable focus barrel, air-assist inlet valve, and focal depth gauge seat.
- Kinematic Mirror Mounts: Dual first and second optical reflection brackets with 45-degree angle indexing and zero-vibration spring tensioning.
- Fitting Variations Supported: A-Type (Y-axis outer fittings, X-axis inner fitting), B-Type (Y-axis outer fittings, X-axis outer fittings), and C-Type (Y-axis inner fittings, X-axis inner fittings).
- Motion Components: High-tensile steel-reinforced 3M/5M polyurethane timing belts, double reduction gears, linear rail carriage mounts, and precision motor brackets for NEMA 23/24 stepper motors.
- Structural Rigidity: Built for continuous industrial processing speeds up to 60,000 mm/min on acrylic, MDF, leather, and wood planks.
