CNC Supplier Outsourced Without Telling You — Parts Arrived Defective
Your CNC parts arrive defective, and only afterward do you discover the supplier outsourced the work without telling you. At that moment, the problem isn’t just quality—it’s that process control was broken without your consent, putting both reliability and schedule at risk. When a CNC supplier outsources your order without disclosure and parts arrive defective, […]
When a CNC Supplier Goes Silent After a Deadline Change, What Now?
You told your CNC supplier the deadline changed. They acknowledged it—but responses slowed, updates became vague, and progress stopped moving. This isn’t a communication issue. It’s often a sign your order has been quietly deprioritized. When a CNC supplier goes quiet after acknowledging a deadline change, your order is usually no longer prioritized. Waiting for […]
CNC Supplier Took Your Deposit but Never Started Machining — What Now?
You paid a deposit, and the supplier says machining has started—but weeks later there’s no material, no parts, and no clear evidence of progress. At this stage, the real risk isn’t the money already paid; it’s losing more time by trusting updates that can’t be verified. If a CNC supplier took your deposit but can’t […]
CNC Supplier Delayed Production for a Bigger Customer? What to Do Next
Your CNC order was scheduled, then progress slowed after a larger customer entered the picture. Updates continue, but nothing moves. If a CNC supplier delays your order to prioritize a bigger customer, don’t wait on promises. Ask for concrete proof that production has restarted. If that proof isn’t available, you should prepare to re-source immediately […]
Was Your Design Leaked by a Supplier? What to Do Next
If a supplier leaked your design, you rarely get confirmation — you notice it through copied features, unexpected knowledge, or look-alike products appearing elsewhere. If you suspect a design leak, do not confront the supplier first. Your priority is to confirm the leak, cut off access, and prevent further file exposure. Only after containment should […]
What Are Your Options If Your CNC Supplier Changed the Material?
When a CNC supplier changes material without approval, parts may fail, assemblies can stop, and responsibility becomes disputed after payment is already made. If your CNC supplier changes material without approval, the options are to reject the parts, require a remake with the specified material, or switch suppliers if correction is not reliable. The sections […]
Is “Waiting for Clarification” a Valid Reason to Stop CNC Production?
When a CNC supplier stops production claiming they were “waiting for clarification”—but no request was ever received—the legitimacy of the delay must be questioned immediately. No. Stopping CNC production for “waiting for clarification” is generally not valid unless the clarification request was clearly delivered and acknowledged after the PO. If the request was never received, […]
CNC Supplier Says Finishing Vendor Caused Delay — Who Pays for It?
CNC Supplier Says Your Tolerances Tighter Than Standard — After PO
Your CNC supplier accepted the PO, then claimed your tolerances are “tighter than standard” and demanded an upcharge. A post-PO tolerance upcharge means the supplier did not validate tolerance capability before quoting. Do not approve the increase unless they prove process and inspection control. The sections below show how to verify the claim, protect your […]
Should You Pay Unexpected Setup Charges Mid-Production?
The supplier accepted your quote. You confirmed the order. Production started. Then comes the message: “We need to add an extra setup charge.” At that point, the explanation doesn’t matter. Once a quote and order are confirmed, all setup and process-planning costs are considered agreed. Any mid-production setup charge without a scope change is a […]
