CNC Machining Processes for Custom Parts
Different CNC parts require different machining strategies. HRCCNC reviews your drawings before production to select the right process, machining sequence, and inspection focus.
01
CNC Milling Parts
Best for housings, brackets, plates, pockets, slots, threaded holes and complex flat or contoured surfaces.
02
CNC Turning Parts
Best for shafts, pins, bushings, spacers, sleeves and round parts requiring diameter and thread control.
03
5-Axis CNC Parts
Best for complex angles, undercuts, multi-side features and precision parts with difficult geometry.
04
EDM / Grinding Parts
Used for hard metals, sharp internal corners, narrow slots and precision‑controlled surfaces.
Engineering Review Before Machining
We review material, tolerance, finish and application requirements before quoting your CNC parts.

Material, Tolerance & Finish Review
Before production, HRCCNC checks your drawings and part requirements to make the quote more practical and reduce machining risk.
Material Review
Select the right material based on strength, weight, corrosion resistance, conductivity and application.
Tolerance Review
Review critical dimensions, threads, holes and mating features according to your 2D drawings.
Finish Review
Plan anodizing, blasting, plating, coating, polishing or laser engraving based on material and final use.
Tip: Send 3D CAD files with 2D drawings when possible, especially for tight tolerances, threads and cosmetic surfaces.

Case Study Section
From Drawing Review to Finished CNC Parts
A customer needed an aluminum dry bath block with precise wells, stable bore spacing and clean internal surfaces for laboratory heating equipment. HRCCNC reviewed the drawing before machining, confirmed the hole depth and machining sequence, and checked the key dimensions before shipment.
Aluminum Dry Bath Block with Precision Wells
This case shows how HRCCNC controls deep-hole accuracy, flatness, burr removal and surface consistency for a CNC machined aluminum block used in sample heating, test tubes and laboratory fixtures.
Material
6061-T6 aluminum for stable machining, good thermal conductivity and dimensional control.
Process
CNC milling, deep-hole drilling, boring, tapping and deburring for precision wells.
Finish
Natural hard anodizing, 12 μm film thickness, with clean surface after machining.
Inspection Focus
Bore diameter, hole depth, spacing, flatness, burr control and clean edge requirements.
