CNC Machining Parts for Machinery

CNC machining parts for machinery

We machine steel parts for machinery builders, with orders ranging from a single part to thousands of pieces. Regular repeat orders are welcome, and we plan capacity so they ship on schedule.

This stainless steel shaft for an industry automation customer is produced in high volume by CNC machining and milling, with heat treatment, to the customer's data sheet.

Heat treatment and machining sequence

Heat treatment increases hardness and wear resistance, but it can also distort the part. The sequence is therefore planned carefully:

• Rough machining with stock left on critical features.
• Heat treatment to the specified hardness, verified by hardness testing.
• Finish machining or grinding of critical diameters after hardening, so final dimensions are not affected by distortion.

Equipment

Our machining shop uses precise high-speed CNC machines such as Makino from Japan and DECKEL MAHO from Germany, plus lathes, grinding machines and wire cutting. Steel components can be held to 0.005 – 0.01 mm where the design requires it.

Every batch is inspected before shipment, and we can supply hardness and dimensional reports with the parts.

How a project like this works

• Tell us what you need – the mold only, molded parts, or both, and your estimated annual volume.
• Send drawings – STEP, IGES, STL, DWG or PDF, or a sample. We sign off moldability in a DFM review.
• Quotation – tooling price, part price and a schedule, with steel, cavities and runner proposed.
• Mold design approval – you approve the 3D mold design before steel is cut.
• T1 samples + FAI report – production or mold shipment starts after your approval.

Shipping molds and parts

• Molds are cleaned, rust-protected, marked and checked against a shipment checklist: cooling circuits, sprue, locating ring, ejection and support pillars.
• Molds ship with drawings, a spare-parts list and the T1 process sheet.
• Parts are packed to your packing instruction and inspected before shipment.
• We ship to customers in Europe, the USA and Asia.

After-sales

Our after-sales team supports mold maintenance and modifications remotely and can supply spare inserts. Contact customerservice@precisemoulds.com.
