Yantai Dongruitai Welding and Cutting Equipment Co., Ltd. is one of the leading manufacturers and suppliers of open type laser cutter in China. We are committed to providing high quality customized machines with low price. Welcome to wholesale the newest open type laser cutter made in China here from our factory. 1 years warranty is available.

This Open Type Laser Cutter is designed for steel structure manufacturers, shipbuilding suppliers, and heavy equipment manufacturers, prioritizing quick material access, crane-assisted top loading, and continuous operation for extra-large plates. Built by Dongruitai Laser under strict CE compliance, the open-frame design eliminates structural clearance barriers, allowing operators to drop full-scale raw stock directly onto the slat bed via gantry cranes or side forklifts.

Core Mechanical Designs & Practical Advantages

Module A: Structural Architecture & Large-Scale Processing Flexibility

Operational Reality: Handling thick, heavy-gauge plates requires unrestricted physical access. Fully enclosed cabins can create clearance limits for overhead shop cranes during drop-loading.
Engineering Response: The machine employs an open-panel layout with low-profile side rails and an extended cutting bed format.
Advantage: Operating as a Large Format Fiber Laser Cutting Machine, this setup simplifies loading sequences for non-standard or oversized steel sheets up to 13 meters long, reducing crane downtime between cycles.

Module B: Frame Integrity under Dynamic Mechanical Loads

Operational Problem: Moving heavy bridge gantries across long bed spans induces torsional stress, which can gradually throw off linear rail alignment and cause edge beveling during straight-line cuts.
Solution: The base frame is constructed from heavy-wall welded steel plate and tubing, subjected to a 600°C thermal annealing cycle, natural cooling, and mechanical vibration stress relief.
Advantage: Neutralizing welding tension ensures that long-span rails retain geometric parallelism over years of multi-shift operation, preventing optical tilt and keeping cut faces perpendicular.

Module C: Motion System & Acceleration Dynamics

Problem: Cutting thick structural stock involves frequent piercing, corner deceleration, and high-speed repositioning across a multi-meter working field.
Engineering Response: The gantry uses Japanese-imported high-torque servo motors driving a precision dual rack-and-pinion transmission. The system supports 4G acceleration rates alongside a 100 m/min maximum traverse speed.
Advantage: High acceleration reduces position dwell time between nested parts. Even on long beds, the system maintains tight position (±0.02 mm) and repeat (±0.02 mm) accuracies during rapid directional changes.

Module D: Power Options, Exhaust & Thermal Control

Problem: Open cutting generates localized smoke, while continuous high-power piercing causes heat accumulation on moving parts.
Design: The platform integrates partitioned lower-bed exhaust dampers that open only under the active cutting zone, paired with an automatic oil-injection system for rail lubrication. Power configurations range from 1.5kW to 60kW.
Advantage: Focused vacuum suction captures airborne particulate directly at the kerf line. As a fiber optic laser cutting machine, it combines low maintenance overhead with scalable fiber source options suited for high-pressure air cutting or deep-penetration oxygen cutting.
