All CNC machining knowledge articles, material guides, process notes, and sourcing resources.
Start with a focused topic path, then use the article guidance to prepare drawings, tolerances, material notes, finishing requirements, and RFQ details.
Use a CNC batch release checklist to verify drawing revision, lot identity, inspection results, certificates, deviations, quantity, and shipment approval.
The first time you hear a GCr15 bearing ring scream under a carbide insert, it’s …
Last month, a shop called about a batch of 40Cr shafts they were turning on a CNC la…
Last month, a batch of 45# steel shafts came off a CNC lathe with a 0.04 mm taper across a 180 mm length. The operator blamed the machine, then the tooling, then the coolant concentration. The real…
Last quarter, a fabrication shop sent us a batch of 200 leveling feet machined from Q235 plate. The drawings called for a 25 mm wide slot, 12 mm deep, with a 1.6 µm Ra finish. Their in-house progra…
Plan prototype CNC machining with a clear test purpose, controlled revision, material, critical features, inspection, validation, and pilot-release path.
The first thing you notice when machining TC5 titanium alloy is the chip. It doesn’t peel away …
TC3 (Ti-5Al-4V) is a near-alpha alpha-beta titanium alloy that sits between commercially pure titanium and the workhorse TC4 / Ti-6Al-4V in strength, with better elevated-temperature stability and weldability than TC4 but lower hardenability. If you are sourcing TC3 CNC machining for parts that see 350–450 °C service, moderate strength, and chloride exposure, TC3 is a
A machinist calls over the shop foreman. The part is a small structural bracket, roughly 150 mm…
Six years ago, a customer sent over a drawing for a pressurized housing used in a regional aircraft environmental control system. The material callout …
When a batch of TA9 valve bodies landed on the shop floor last month, the existing titanium setup sheets were pract…
Define CNC machining quality documents before RFQ: dimensional reports, CMM data, material certs, CoC, FAI, traceability, and deviation records.
Reduce CNC machining lead time by controlling drawings, material, approvals, finishing, inspection, shipping, and rush priorities before PO release.
Plan CNC first article inspection with a clear FAI scope, ballooned drawing, measured results, certificates, approval gate, and repeat triggers.
Understand low-volume CNC machining costs, quantity breaks, MOQ, lead time, DFM, inspection, and supplier decisions for prototype and pilot parts.
Evaluate a CNC machining supplier in China using technical review, quality evidence, traceability, inspection, communication, and a sample order.
Prepare a complete CNC machining RFQ with CAD files, drawings, material, quantity, tolerances, finishing, inspection, and delivery requirements.
Every so often, a purchase order lands on the desk with a material line that makes an experienced machinist stop mid-coffee: TA7. Not the workhorse Ti-6Al-4V that d…
When a batch of TA5 titanium forgings lands on a pallet in a busy job shop, the first reaction is often cautious. Not becau…
