Engineering Resources

This page collects everything we publish for people who have to read a drawing, check a tolerance or compare a quote. The reference tables are the ones our own engineers use on the shop floor. The blog articles go deeper on single subjects, and the video library shows the parts and the cutting operations behind them.

Guides and answers

• Engineering Blog
  Long form guides on tolerances, materials, design for manufacturing, cost drivers and inspection, written by the KGL engineering team.
• Design Tips
  Design for manufacturing rules that remove cost without removing function.
• FAQ
  Straight answers on quoting, minimum order quantity, certificates, tolerances and lead times.

Engineering reference

• Engineering Reference
  Tolerance tables, ISO grade charts and fit data for reading and checking a machining drawing.
• Material Reference
  Machinability, stock forms and typical uses for the metals and plastics we machine most.
• Aluminum Library
  Grade by grade notes on the aluminium alloys that cover most CNC work.
• Surface Finish Reference
  Ra values, the machining methods behind them and the finish each method really delivers.
• Machining Accuracy
  What each process and machine class holds in normal production, and what needs extra care.

Shop floor and company

• Machining Video Library
  Short clips of real parts and real cutting operations, filmed in the Shenzhen shop.
• News
  Certification milestones, equipment additions and company announcements.
• Knowledge Hub
  Converted shop knowledge: machining handbooks and engineering references.
• Case Studies
  How specific parts were quoted, set up, machined and inspected.
