CNC Machining Custom Metal Parts: Tolerance Control & Full Auxiliary Processing

CNC Machining Custom Metal Parts: Tolerance Control & Full Auxiliary Processing

High-precision mechanical assembly parts, electronic hardware accessories, auto spare parts rely on CNC machining for tight tolerance requirements. Many buyers receive defective products due to unclear CNC tolerance standards. KAISHI Hardware integrates CNC machining with sheet metal, stamping, welding to realize one-stop precision metal part customization.

What Parts Need CNC Secondary Machining?

Laser cutting & stamping parts can only complete basic outlines. CNC milling, drilling, tapping, boring processes add precise features: threaded holes, countersinks, positioning slots, flat sealing surfaces, tolerance up to ±0.01mm.

Matching Crafts: CNC + Sheet Metal / Stamping / Deep Drawing

Our integrated production line workflow:

Laser cutting blanking → stamping forming → CNC precision secondary processing → welding assembly → surface finishing

This integrated process avoids repeated positioning errors caused by multiple factories processing separately, greatly improves product yield.

Strict QC Standard For CNC Machining

We use calipers, micrometers, CMM three-coordinate measuring instrument to inspect all sample & batch parts, strictly follow ISO tolerance standards, provide inspection report for every shipment.

Send Drawings/Samples For CNC Rapid Prototyping

No matter small batch prototype or large-volume mass production, you only need to send:

- 2D drawing with marked tolerance, material grade, processing requirements

- Or physical samples for reverse engineering

Our technical team replies processing plan & quotation within 24 hours, complete sample delivery in 3–5 working days.

20 years hardware manufacturing experience, independent mold R&D team, full set of laser cutting, stamping, deep drawing, CNC, welding, surface treatment equipment, located in Nanpi County, Hebei, supply OEM metal parts to global machinery, medical, new energy clients.
