Abstract

General Background Portable screw compressors represent critical pneumatic assets widely utilized across demanding industrial field operations such as sandblasting and drilling. Specific Background Continuous high-load operation subjects these units to severe thermal stress, lubrication degradation, and component wear, leading to performance deterioration. Knowledge Gap Although maintenance procedures are recognized, comprehensive empirical evaluations detailing the systematic overhaul stages and specific valve degradation patterns for Ingersoll Rand 375 units remain limited. Aims This study aims to analyze the overhaul stages and identify potential component damages resulting from intensive field utilization in screw compressors. Results Technical observations and post-repair testing demonstrate that standard-compliant overhaul successfully restores operational air pressure, achieves thermal and rotational stability, and extends mechanical service life. Novelty This research provides a structured procedural breakdown of cylinder head dismantling and valve replacement within a commercial maintenance workshop setting. Implications Implementing structured overhaul protocols and routine maintenance practices prevents premature mechanical failures, optimizes operational costs, and ensures sustained reliability for industrial pneumatic systems. Key Findings Highlights Systematic overhaul execution successfully restores compressor operating pressure, working efficiency, and structural reliability. Post-repair testing confirms that engine parameters, including idling speed, working speed, coolant temperature, and oil temperature, operate within normal stable ranges. Intensive field utilization primarily causes thermal fatigue, carbon accumulation, and wear on critical components such as valves and cylinder heads.

Abstract

CNC laser cutting machines play an important role in manufacturing processes due to their high precision and cutting efficiency; however, operational problems such as overheating often occur and can reduce machine performance and disrupt production continuity. General Background Overheating in CNC laser cutting machines is generally related to high operational loads, improper cutting parameter settings, and inadequate cooling system performance, particularly in the laser source component, which serves as the primary heat generator. Specific Background The method used in this study includes direct observation during industrial internship activities, interviews with operators and technicians, and problem analysis using a fishbone diagram and Value Stream Mapping. Knowledge Gap Existing operations lack systematic evaluations linking cooling system instabilities and non-optimal operating patterns to thermal failures in laser cutting equipment. Aims This study aims to examine overheating problems and determine root causes and corrective measures for CNC laser cutting machines. Results The results of the analysis indicate that overheating is mainly caused by instability in the laser source cooling system and non-optimal machine operating patterns. Novelty This work establishes an integrated framework combining fishbone root-cause analysis with Value Stream Mapping to optimize thermal management in CNC laser cutting lines. Implications Implementing proper adjustment of operating parameters, preventive maintenance, and cooling system optimization enhances the reliability and efficiency of CNC laser cutting machines. Key Findings Highlights Overheating in computer numerical control laser cutting machines stems predominantly from high operational loads and unstable cooling system performance. Fishbone diagram analysis successfully maps core root causes across man, machine, method, material, and environmental categories. Implementing structured preventive maintenance and optimized operating parameters significantly reduces thermal downtime and stabilizes production continuity.
