alloy steel · carburizing and quenching
Alloy steel drill bushings are used in drill jigs and tooling under high-load, high-frequency use, requiring high surface hardness and wear resistance in the inner bore.
After carburizing and quenching, the inner bore is ground, with hardness and hardened layer depth controlled per process requirements, and end faces chamfered to avoid stress concentration.
Customization per customer drawings is supported, with STEP / DWG / PDF formats accepted; material certificates, first-article inspection reports and finished product inspection reports are provided, prototyping takes 5-10 business days, and volume orders are delivered per the scheduling plan.
2026-09-15In high-end equipment manufacturing, ±0.005mm tolerance has become standard for precision parts. This article shares key technical points across five dimensions: equipment selection, cutting tool selection, fixturing methods, environment control and inspection.
2026-09-08To meet growing demand for complex part machining, the company added two Mikron 5-axis simultaneous machining centers, raising complex curved part capacity by about 40%.
2026-08-28Scheduling and inspection processes were optimized for small-batch, multi-variety orders, shortening the average delivery cycle by about 20% and earning written praise from customers.
