Chinese CNC quote: four lines before you pay the deposit

Uzair bin Haroon

Four things, in writing, before any money moves. The control, by make and version, and who holds a spindle drive and an axis amplifier for it within reach of your shop. A delivery date with a per-week deduction after it. The acceptance test data to ISO 230-2, printed and packed in the crate. And, if the machine is five-axis or a precision grinder, the Chinese export approval step written into the delivery clause, with your deposit refundable if approval is refused.

Pushing the price down another two per cent is the wrong fight this year. The date is the exposure, and so is the control.

Why your order is the one that slips

A Chinese builder's home order book is filling faster than his export book. CMTBA's first-half figures, reported by AMT, put China's metalworking machine tool exports at $4.57 billion, up 0.3 per cent on the year — three tenths of one per cent — while new orders for metal-cutting machines rose 20.5 per cent, driven by parts for liquid-cooled AI servers, precision server components, humanoid robot components and battery storage. A builder selling everything he makes to customers who pay in yuan and collect by truck has no reason to stretch for a foreign delivery date, and no reason to discount to win one either. Expect the quoted lead time to be the optimistic case unless something makes slipping it expensive for him, which is what the per-week deduction is for.

The control is the part that changes without anyone telling you. China's imports of CNC control systems rose nearly 21 per cent in the first quarter on the same association's figures: builders buy in the controls that go into export machines, mostly from Japan and Germany. Unless the purchase order names one, the control in your crate is whichever was on the shelf the week the machine was built. That decides what a failed drive costs you in three years, and whether anyone within a day's drive can diagnose it. “We order from the factory” is an answer — price two idle weeks into the machine if that is the answer you get.

Why the acceptance printout is worth asking for

ISO 230-2 is the standard method for positioning accuracy and repeatability on a numerically controlled machine. A builder who ran the test before packing and put the sheet in the crate has told you something about his assembly floor; one who will not has told you something as well. It costs him an hour, and it is the only evidence you will have before the machine is on your floor and the deposit is spent. Ask for the data against the axes and travels you are buying, not a certificate of conformity that names a standard and no numbers.

The export approval line applies to fewer machines than people assume. Since 30 June, in the Taiwanese makers' association's description of the rule, mainland China requires prior declaration and approval before high-precision and dual-use machine tools are exported. A standard three-axis vertical is unlikely to be caught by it; a five-axis machine or a jig grinder may be. Put in writing who files the application, how long it takes and what happens to the deposit if it is refused — the same clause, set beside a Taiwanese and a Japanese quote, is in two machine quotes, two currencies: which is cheaper?

Between the deposit and the crate there are usually several months of parts you still have to deliver. Vesprr Workshop machines and fabricates to drawing: send the drawings and the quantities and the work carries on while the machine is on the water.
