Fiber Laser Source

High-Efficiency Laser Source

The single-module continuous fiber laser is a high-power fiber laser with high electro-optical conversion efficiency, compact size, good beam quality, and maintenance-free operation. 

Heavy-Duty Machine Bed

Heavy-Duty Steel Welded Bed

Constructed from thick steel plates, subjected to heat treatment, milling, nature cooling and high precision welding. Guarantees zero deformation for up to 20 years of continuous use.

Aviation Aluminum Beam

Aviation Tensile Aluminum Beam

Extruded under 4300 tons of pressure. Offers incredible rigidity while remaining lightweight, enabling ultra-fast acceleration and moving speeds.

High-Quality Consumables

Long-Life Stable Taiwan Rack

The rack and pinion is one of the core components of the transmission system of a laser cutting machine. It is mainly responsible for converting the rotary motion of the servo motor into linear motion, thereby driving the crossbeam or cutting head to move at high speed and with precision.

Fiber Laser Cutting Capacity Guide

Engineered for precision and heavy-duty industrial applications. Review our standard cutting parameters for 1.5kW to 6kW laser sources to determine the optimal configuration for your manufacturing needs.

Laser Power Carbon Steel (Max) Stainless Steel (Max)
20000W 45 mm 40 mm
30000W  50 mm 40 mm
40000W  70 mm 70 mm
60000W  100 mm 100 mm
* Note: Maximum cutting thickness depends on material quality, assist gas (O2/N2), and optical lens configuration. For optimal edge quality, continuous production thickness is typically 60%-70% of the maximum capacity.

Laser Cutting Machine Process

How to Choose the Right Power?

  • 1

    Identify Primary Materials: Carbon steel requires oxygen for thicker cuts, while stainless steel relies on high-pressure nitrogen. Ensure your power choice aligns with your most frequently cut metal.

  • 2

    Assess Production Volume: If your daily workload involves cutting 12mm carbon steel continuously, do not choose a 1.5kw machine (its absolute limit). Upgrade to 2kW or 3kW for faster speeds and burr-free edges.

  • 3

    Future-Proof Your Investment: Business grows. Selecting a machine 1-2 levels higher than your current absolute minimum requirement saves future upgrade costs.

Maintenance & Operations

Laser Consumables Replacement Guide

To ensure your LSENTR fiber laser cutting machine operates at peak performance and maintains cutting precision, regular inspection and replacement of consumables is critical. Below is the recommended replacement frequency and estimated annual usage for standard B2B production environments.

Laser Cutting Nozzle
High Wear

Cutting Nozzle

Replacement Freq: 3 - 6 Days
Annual Usage: 50 - 80 pcs

Directly affects gas flow and cut quality. Replace immediately if deformed by collisions or heavy slag accumulation.

Protective Lens
High Wear

Protective Lens

Replacement Freq: 2 - 7 Days
Annual Usage: 200-300 pcs

Protects internal optics from spatter. Must be kept perfectly clean. Replace if burn spots or permanent debris are visible.

Ceramic Ring
Medium Wear

Ceramic Ring

Replacement Freq: 1 - 2 Weeks
25Annual Usage: 25 - 30 pcs

Transmits capacitance signals for height adjustment. Prone to cracking upon collision. Requires replacement if signal is unstable.

Dust Cover
Medium Wear

Dust Cover (Bellows)

Replacement Freq: 3 - 6 Months
Annual Usage: 2 - 4 pcs

Shields linear guides and racks from metallic dust. Replace if torn or heavily burnt to prevent mechanical failure.

Table Slats / Blades
Low Wear

Table Slats (Blades)

Replacement Freq: 6 - 12 Months
Annual Usage: 1 - 2 Sets

Supports the metal sheets during cutting. Continuous laser reflection and slag build-up will eventually compromise levelness. Customer can cutting blades by themselves.
