A Zinc Alloy Nickel Alloy Tapping Parts Parts CNC produces accurate hole patterns and threads, where position accuracy and chip evacuation decide whether the part passes inspection. Supplied to medical device manufacturers, this Zinc Alloy Nickel Alloy Tapping Parts Parts CNC is configured with 316L stainless steel. CNC drilling, rigid tapping and boring with peck cycles for chip control is carried out on equipment that holds hole position ±0.05 mm across a full shift, not only on a first piece.
Tolerance is applied where it does work rather than across the whole drawing. Critical features are held to hole position ±0.05 mm, non-critical dimensions follow the general machining tolerance, and the difference is stated in the quotation rather than discovered later.

Manufacturing process
Work is carried out with CNC drilling, rigid tapping and boring with peck cycles for chip control. Tooling, speeds and fixturing are recorded with the part number, so a repeat order starts from a proven process instead of a fresh setup.
Material is purchased against a certificate and checked on receipt, so the composition is known before any cutting starts. Work in progress is identified by part number and operation, and the finished parts are deburred, cleaned and protected before they leave the machine area.
Typical applications
Most of the work supplied in this category falls into the following examples.
- Flange bolt circles.
- Manifold port drilling.
- Mould cooling channel drilling.
- Structural steel connection plates.
- Heat exchanger tube plates.
Quality control and documentation
Critical features are measured on calibrated equipment in a controlled room, and the results are filed with the job so that a repeat order can be compared with the first.
Material certificates to EN 10204 3.1, dimensional reports and first article inspection reports are issued with the shipment where the application requires them. Calibration dates and measurement uncertainty are recorded alongside every result.
Ordering, lead time and packaging
Packaging is specified by the part: individual protection for finished surfaces, separation for assemblies, and export crating with a packing list for shipment.
Frequently asked questions
How accurate are drilled hole positions?
Position is normally held within 0.05 mm, and reaming or boring brings size to H7. Spotting the hole first and using a rigid setup matters more than spindle speed.
Can you drill deep holes without drifting?
Yes, with gun drilling and high pressure coolant. Depth to diameter ratios above 10:1 need guided tooling and controlled pecking rather than a standard twist drill.
How long does delivery take?
Sample parts are typically shipped in 7 to 15 working days after drawing approval. Production batches run 3 to 4 weeks depending on quantity, finishing and inspection requirements.
Drawings are reviewed for manufacturability before quotation, and any feature that adds cost without adding function is pointed out at that stage rather than after the parts are made.
