Chicago CNC shops run on tight margins. Cycle times, tooling costs, and part quality all depend on the bar stock you choose. Pick the wrong
If you spec 8620 Round Bar for camshafts or gears, it has probably crossed your desk. It carburizes predictably, machines cleanly before heat treatment, and
When a cutting-edge product has to survive thousands of production cycles, the grade you start with decides everything. Manufacturers across the Chicago area know this
Choosing between 430 and 440 stainless steel round bars is a common decision for engineers and procurement teams. Both are 400 series grades. Both are
When a bearing seizes mid-run, the cause usually traces back to one early decision: the bar stock grade used for the shaft. At Precision Ground
Inconel 625 bar stock is the material engineers reach for when standard stainless grades have already failed the spec. It handles extreme heat, aggressive chemicals,
Bar stock that isn’t straight causes real problems in rotating shaft applications. Bearings wear faster, packings fail early, and vibration builds up under load. Most
Bar cutting looks simple. You order stock, it gets cut, and you load it into your machine. But when finished parts come out off-tolerance, and
Shafts and spindles running under cyclic loads need a grade that holds its shape after machining. Standard carbon steel often falls short in those conditions.
Screw machine shops and Swiss machine operations regularly ask us about 410 and 416 stainless bar stock. Both grades are martensitic stainless. Both are in
