Questions we get asked

Yes. BC Engineering Works machines all parts at our own workshop in Saddique Nagar, Ghaziabad and delivers to Delhi NCR regularly. Send your drawing or sample on WhatsApp at +91 82853 12726 and you will normally have a quotation the same working day.

Send a drawing (PDF, DWG, STEP or a clear photo of the part), the material you want, the quantity and your delivery date. If you do not have a drawing, send the sample part or a sketch with the critical dimensions marked. Quotations are usually issued within one working day.

There is no fixed minimum. We machine single prototype pieces as well as production batches of 50,000 and above. Single pieces carry a higher per-piece rate because setup time is spread over one part instead of a batch.

Routine production work is held to plus or minus 0.01 mm on turned diameters with a surface finish of Ra 0.8 to Ra 1.6 micron. Tighter tolerances are possible on specific features; send the drawing and we will confirm what is achievable before quoting.

Mild steel, EN8, EN19, EN24, EN31, stainless steel 304 and 316, brass, aluminium, alloy steel and free-cutting steel. We can either machine from material you supply or source the bar stock ourselves and include it in the quotation.

Machining lead time is typically 3 to 10 working days depending on quantity and material availability. Dispatch to Delhi NCR is then same day or next day. Urgent and breakdown jobs can be prioritised on request.

Yes. BC Engineering Works is GST registered under GSTIN 09APOPL3370D1ZS and every despatch goes out with a proper GST tax invoice, so the full input credit is available to you.

Yes. Send the physical sample to the workshop. We measure it, produce a working drawing for your approval and then machine against that approved drawing, so there is a documented reference for repeat orders.

Yes. Once a part has been approved we keep the programme, tooling setup and approved drawing on file. Repeat orders therefore skip development time and are quoted at the established rate.

Every batch is checked against the drawing with micrometers, vernier calipers, bore gauges and thread gauges. Critical dimensions are inspected on 100 percent of the batch rather than sampled, and we can supply a dimensional report with the consignment on request.

Both. Parts can be collected from the Ghaziabad workshop, sent by transport to Delhi NCR, or delivered by our own vehicle for nearby locations. Freight is quoted separately so you can compare it against your own arrangements.

New customers normally start with advance or part-advance against the proforma invoice. Credit terms are opened once an account has an order history with us. We accept bank transfer, UPI and cheque.

Standard production finish is Ra 0.8 to Ra 1.6 micron straight off the CNC turning centre, with no secondary polishing needed for most applications. Where a finer finish is specified we plan an extra finishing pass into the cycle.

Yes. Where both diameters can be turned in a single chucking we hold them concentric within the same setup, which is far more reliable than re-chucking. Mark the datum on your drawing so we can plan the setup around it.

Metric coarse and fine, BSW, BSF, UNC, UNF and BSP. Threads are single-point cut on the CNC rather than die-cut, so pitch and flank angle stay inside gauge over the full length.

Yes. Zinc plating, black oxide and phosphating are arranged through our regular plating vendors. Tell us the finish at enquiry stage so the correct machining allowance is left on the thread.

On posts up to 500 mm we work with centre support and light finishing cuts to control deflection and keep runout low. For long slender parts, tell us the length-to-diameter ratio at enquiry stage so we can plan the support and quote realistically.

Yes. Send the sample and we will measure it, produce a drawing, confirm the critical dimensions with you and quote against that approved drawing.

Yes. Free-issue material is welcome. We record the material in and out so your stock reconciles, and quote machining charges only.

Yes. Give us the groove standard or the ring part number and we will cut the groove to the correct width, depth and corner radius so the seal seats properly and the retaining ring holds.

Cut on the CNC by single-point threading. This gives a cleaner thread form and much better pitch consistency over length than rolled thread, which matters on lead screws and long tie rods.

Yes. ACME, trapezoidal and square thread forms in single or multi-start. Specify the lead, the number of starts and the required backlash with the mating nut when you enquire.
