Description
The QH-4020F is an integrated sheet metal processing solution designed for welding prefabrication scenarios, combining high-precision beveling cutting capabilities with large-format processing performance—ideal for industries like heavy machinery, steel structures, and industrial equipment that require consistent, high-quality beveled edges for weld joints. Its core differentiation lies in the built-in beveling system: supporting a flexible bevel angle range of ±45° (adjustable in 0.1° increments) and multi-type bevel profiles (V-type, U-type, Y-type, and single/double-sided bevels), it eliminates secondary beveling processes (e.g., grinding or milling) common in traditional manufacturing, directly delivering weld-ready edges.

Quick Detail

Beveling Core: ±45° adjustable bevel angle (±0.5° accuracy); supports V/U/Y/single/double-sided bevels—eliminates secondary processing.​

Key Specs: 4000×2000mm large processing area (100kg max load), ±0.03mm axis precision (maintained during beveling), 1500W-20KW power (0.5-25mm material beveling).​

Efficiency: 100m/min linkage speed + 1.0G acceleration cuts bevel time by 40% vs. traditional methods.​

Fit: Welding-focused industries (steel structures/heavy machinery); 380V/50Hz industrial power compatibility.

Advantage

Precision Beveling Ensures Weld Joint Quality: The double rack & pinion servo transmission system stabilizes bevel cutting motion, maintaining ±0.03mm axis accuracy and ±0.5° bevel angle error—critical for weld joint fit-up. Unlike manual beveling (prone to angle inconsistency), this uniformity reduces weld rework rates by 45%-55%, especially for high-strength steel structures where bevel precision directly impacts load-bearing performance.​

Large-Format Beveling Eliminates Split Errors: The 4000×2000mm processing area allows one-time beveling of oversized workpieces (e.g., 4m-long equipment panels) without splitting. This avoids bevel misalignment at 拼接 seams (a common issue with small-format machines) and cuts overall processing time by 30%-35%, as no additional alignment or rework is needed for split parts.​

Power Versatility for Multi-Thickness Beveling: The 1500W-20KW laser power range adapts to diverse beveling needs: low power (1500W-5KW) for precision beveling of thin materials (0.5-5mm aluminum sheets for hardware parts), and high power (15KW-20KW) for deep-penetration beveling of thick carbon steel (20-25mm for heavy machinery frames). This eliminates the need for separate beveling equipment for different thicknesses, lowering capital investment.
