Case 4: A specialized production device for eight‑shaped oil grooves, independently designed and manufactured by KGBAL.
1. Labor productivity improvement: Conventional processing method: 4 minutes per piece; KGBAL-specific equipment: 1 minute per piece.
2. Previously, when using conventional machining methods, the amount of material removed per pass could not be standardized or programmed, resulting in variations between individual parts. By employing KGBAL’s specialized equipment, inter‑part variability has been eliminated, thereby achieving consistent product quality.
3. KGBAL is the core supplier of LIEBHERR’s figure‑eight oil tank products.
