Apex Enterprises – MAZAK VMC Retrofitting and Reconditioning

Executive Summary

Apex Enterprises faced a critical production challenge with their 20+ year-old MAZAK Vertical Machining Center (VMC). The machine suffered from severe mechanical degradation, outdated Mazatrol CNC controllers, and a breakdown rate as high as 20%. These issues resulted in frequent production errors, increased job rejections, reduced capacity, and operator dependency—ultimately impacting customer deliveries and profitability.

Tulja Hi-Tech Automations Pvt. Ltd. addressed this challenge through a complete mechanical and electrical overhaul. Precision grinding restored geometrical accuracies; new ball screws, spindle bearings, and rewiring were installed; and the entire system was upgraded with a Siemens 828 CNC system. Hands-on training and complete documentation were also provided.

Results included:

  • 90% reduction in maintenance downtime
  • 40% improvement in production efficiency
  • Near-zero job rejections
  • Greater machine independence for the client’s internal team
