At Aerostar Manufacturing, our Journal Machining process – MT-KAM-8022, is a showcase of our commitment to precision, quality, and global manufacturing standards. Starting from the moment we receive the raw materials, through the multiple stages of machining, we employ stringent practices to ensure the production of superior aerospace components.


Aerostar Manufacturing is a reputable automotive component manufacturer known for its commitment to precision and quality. One of their critical processes is the Journal Machining (MT-KAM-8022), which involves several steps to ensure the production of high-quality parts that meet the stringent demands of the aerospace industry.

The process begins with receiving the raw materials, which are stored meticulously in compliance with the W15_0002 standard to maintain their optimal condition. The parts then go through various machining stages, including machine operations on lathes and mills, and broaching. During each step, the Machine Operator plays a crucial role in ensuring the parts are well-machined and meet the required specifications.

Aerostar Manufacturing places great emphasis on cleanliness and precision during the machine operation. The Machine Operator diligently ensures that soft jaws and pad locators are clean, and the parts are correctly positioned and clamped. After each operation, the parts are carefully inspected to ensure they meet the strict quality standards.

The company also follows a meticulous storage process when required, utilizing the Journal Tray identification W15_0255 to identify the correct trays. These trays are cleaned before use, and the parts are packed and moved to Op-20 after applying Rust Preventative (Protech 1300) to safeguard the machined surfaces.

Aerostar Manufacturing maintains its exceptional quality standards through adherence to ISO certifications applicable to the Journal machining process. The company proudly holds ISO 9001:2015 for their Quality Management System and ISO 14001:2015 for Environmental Management System. These certifications reflect the company’s dedication to upholding global standards in automotive manufacturing and consistently delivering reliable and high-performance components to their customers.

In conclusion, Aerostar Manufacturing’s Journal Machining process stands as a testament to their commitment to precision, quality, and compliance with international standards. Through their diligent machine operations, thorough inspections, and adherence to ISO certifications, the company continues to be a preferred partner in the aerospace industry, ensuring the delivery of flawless components that meet the highest expectations of their customers.


Project Overview

Quality, Inspection, and Measurements Steps

  • Material receipt and initial inspection
  • Visual confirmation of the correct material
  • Specific dimension checks
  • Surface integrity inspection (Scratches, dings, corrosion, contamination)
  • Checking sharp edges and burrs
  • In-process inspection
  • Specialized inspections as needed (e.g., lab inspections)
  • Storage conditions checks
  • Final inspection and packing
  • Shipping inspection

Equipment and Tools Used for Quality and Inspection Steps:

  • Visual inspection
  • Go / NoGo Spline Gage
  • 1-2-3 Blocks & Indicator
  • UD (Tri-Chek) Gage
  • ID Gage (Mueller)
  • Calipers.
  • Runout Gage.
  • Snap Gage.
  • Master Jo Blocks.
  • Tri-Check Gage & Master Part.

Inspection steps often follow manufacturing steps. For instance, after a part is processed using a machine, it’s checked
visually for quality and conformity to standards.

Manufacturing Steps

  • Material receipt
  • Material storage
  • Initial machine processing (e.g., Lathe, Milling)
  • Specialized processes (e.g., Broaching)
  • In-process handling and part management
  • Apply protective measures (e.g., Spraying against rust)
  • Final machining and finishing operations
  • Parts stacking and organization
  • Tagging and documenting parts for traceability
  • Shipping preparation
