Machining
Chips, inserts and VHM residue from manufacturing – the questions from machining.
In machining, the proceeds are generated not on the day of sale, but on the machine. Those who put their own container beside each other have batches of pure grades at the end of the month; those who use a collection container have mixed chips, and mixed chips are their own lower grade. The same applies to tools: solid carbide, HSS and carbide-fitting steel bodies in three boxes instead of one.
The second size is residual moisture. Drained chips lose part of the cooling lubricant, hurled much more, briquettes most — and the briquettes have a side effect: it takes a fraction of the volume, which means a pick-up is carried earlier. The separated emulsion is not a purchase material, it belongs with its own waste key in the operational disposal.
Legally, the obligation to separate industrial waste is based on this: metal fractions do not belong in the mixed container. This obligation is in the hands of the company, because what is kept separate can be sold instead of disposed of — and the credit fits into the same file as the other evidence.
Do you accept chips with cooling lubricant?
Yes, they are assumed, but emulsion and oil lower the classification: The liquid weighs along on the calibrated balance, it is not paid, and when melted it does rework. Drain the chips in the container, or even fling or briquette. Free standing emulsion in the barrel is the most common reason for a lower grade.
Do I have to remove inserts from the cassettes?
Yeah, it's almost always worth it. The plate itself is solid carbide, cassette, clamp holder and carrier body are steel. If they stay on, they're connected in the container and the analysis is lower. The release takes seconds per plate. Killed cuttings on steel bodies belong in a separate container, not to the loose plates.
How do I know whether a tool is HSS or solid carbide?
Weight and magnet. Solid carbide is about twice as heavy as HSS of the same size and adheres to the magnet only weakly, HSS clearly. In addition, the fractured edge: carbide breaks brittle and splinters, HSS bends rather. In case of doubt, put the tool aside, because we evaluate mixed containers according to the weaker grade.
How many times do you pick up?
From 500 kg, and the clock depends on your level, not on the calendar. With chips from ongoing production, these are often a few weeks, and with carbide it takes longer because the weight is stuck in a bucket. We agree to regular pick-up by arrangement. Depending on the distance between 40 and 350 euros, the pick-up costs are fixed before the trip.
Can I get a credit for the bookkeeping?
Yeah. We charge for commercial deliveries by credit in accordance with § 14 para. 2 VATG, so you do not write an invoice. VAT is not based on the fact that the recipient of the benefit owes the tax on scrap metal, § 13b para. 2 no. 7 VATG. In addition, the weighing slip of the calibrated scale with grade, weight and date; is paid within 24 hours.
