Laser cutting machine SF3015H

for stainless steelfor metalsheet metal

Product Overview
The SF3015H5 is an ultra-high-power, heavy-duty laser cutting machine from SENFENG LASER developed for large-format, ultra-long and super-thick sheet applications. It consolidates years of R&D and user feedback to support continuous technical upgrades. The machine delivers high cutting speed on thin sheets and extended cutting capability for thick plates to meet diverse industrial production needs.

Highlights

• Power up to 50kW
• Max acceleration 2.8G
• Max no-load speed 200 m/min
• Capable of cutting up to 100 mm stainless steel (configuration dependent)
• Maximum sheet support up to 12100*2530 mm (model dependent)

Key Features

• Ultra-high-power laser source options: 12 / 15 / 20 / 30 / 40 / 50 kW
• Cutting head engineered for high-temperature, high-pressure and high-humidity environments
• Auto-focusing and collision protection
• Real-time monitoring of protective lens temperature and air pressure with alarm on abnormality
• Intelligent piercing with immediate transition to cutting
• Spring-seal failure detection for stable production
• Fully enclosed machine body with intelligent spiral negative-pressure dust extraction and adaptive air vents
• Time-shared exhaust zoning to remove cutting smoke, dust and heat
• Bottom U-shaped seal structure for improved smoke control
• Large-format spliced machine bed (customizable up to 6–12 m) with heat-isolated hollow bed
• Double exchange platforms with deviation correction for loading/unloading thick sheets
• Aircraft-grade aluminum beam for stable motion
• EtherCAT-based intelligent bus CNC system with fast, stable data transmission
• Built-in cutting database and real-time memory cache
• Integrated automatic nesting software for optimized material utilization
