alloy steel · hardened guide bushing
Alloy steel drill bushings are carburized and quenched, then inner-bore ground; hardness and hardened layer depth determine wear life, while inner bore dimensional accuracy determines guiding accuracy.
After carburizing and quenching, the inner bore is ground to final dimensions, with hardness and hardened layer depth controlled per process requirements; end faces are chamfered to avoid stress concentration, and demagnetization and cleaning are performed after grinding to prevent residual magnetism from attracting iron chips and affecting guidance.
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 3-7 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.
