We successfully completed a repair project for an AMADA FOM II 3015NT laser cutting machine in Indonesia, resolving system errors remotely, replacing key components, aligning the system, and restoring optimal cutting performance up to 16mm thickness—ensuring stable machine operation without further issues post-repair.

Project Overview

LECI undertook a complex repair assignment in Indonesia for the AMADA FOM II 3015NT model, featuring an AMNC-F control unit and AF4000i-B laser oscillator.

Key project challenges included:

  • No onsite inspection was possible—diagnosis relied entirely on videos, photos, and customer-provided descriptions.
  • Urgent timeline with a requirement for in-stock replacement parts.
  • Budget constraints requiring cost-effective and efficient solutions.
  • Difficult travel conditions, demanding precise preparation and flawless execution.

Cutting samples provided by the customer

Image 1:

  • Burned edges on round and rectangular holes
  • Thick burrs indicate weak assist gas or incorrect cutting speed
  • Possible focus misalignment or uneven beam distribution

Image 2 (U-shape cut):

  • Severe edge burning
  • Jagged, incomplete cuts—likely due to insufficient laser power
  • Accumulated slag from trapped molten metal

Image 3:

  • Small round holes poorly formed, excessive burrs and slag
  • Signs of re-melting and uneven cut edges

Proposed Technical Solution

LECI recommended full system inspection, preventive maintenance, and replacement of key wear parts to restore cutting performance:

  • Replace 10 internal mirrors
  • Replace 6 external mirrors
  • Replace protective gas filters (10,000h and 5,000h)
  • Replace deionized water filter
  • Replace 12 dust collector filters
  • Replace main air filter

Execution & Handover

Two LECI engineers traveled to the customer site in Indonesia and completed the full repair process in just 16 consecutive working hours.

Scope of Work:

  • Comprehensive system diagnostics via control panel and component evaluation
  • Replacement of all worn components: 10 internal mirrors, 6 external mirrors, gas filters (10,000h & 5,000h), deionized filter, 12 dust filters, and main air filter
  • Precise calibration of nozzle focus, Z-axis movement, cutting speed, and gas pressure
  • Final testing and acceptance with cutting quality restored up to 16mm thickness—clean, sharp edges with no burrs

Post-Repair Results

After the repair and recalibration, the AMADA laser cutting machine resumed stable operation with no further errors reported.

Improved Cutting Performance:

  • Sharp, burr-free cuts with no need for post-processing
  • Stable cutting speed and high repeatability, ensuring continuous production efficiency
  • Successful cutting of steel sheets up to 16mm, confirming optimal laser power and focus calibration
