What Is Metal CNC Machining?
Metal CNC machining shapes metal blanks through milling, turning, drilling, tapping, EDM, and finishing operations using computer-controlled equipment. JADE-CNC supports CNC milling machining for CNC milling metals, as well as turned metal components, prototypes, fixtures, housings, brackets, shafts, and production parts that need stable dimensions and repeatable inspection.
Types of Metal CNC Machining
During RFQ machining review, JADE-CNC confirms the material grade, stock form, machining tolerance, surface finish, documentation needs, and schedule based on the drawing and available supply. For aluminum metal cutting, machining aluminum parts, or producing other metal components, our team checks machinability, fixture access, burr risk, coating impact, and inspection method before production.

Metal CNC Turning
The workpiece rotates while the cutting tool removes material, making turning suitable for shafts, bushings, pins, sleeves, threaded parts, and other cylindrical metal components.

Metal CNC Milling
Rotating cutting tools remove material from a fixed workpiece, making milling suitable for plates, housings, brackets, pockets, slots, complex contours, and precision metal features.

Metal CNC Drilling
Used for creating holes and threads.

Wire EDM
Used for machining conductive metals with high hardness or complex geometries.
What JADE-CNC Reviews Before Metal CNC Machining
Metal parts can fail manufacturing expectations when material, geometry, surface finish, tolerance, and inspection requirements are treated separately. JADE-CNC reviews these points together so the machining route can match the drawing and application.
Metal Grade and Stock Form
Material grade, hardness, stock size, blank allowance, equivalent material options, and documentation needs are checked before machining route planning.
Machining Route and Tool Access
Milling, turning, drilling, tapping, EDM, and multi-axis access are reviewed around pockets, holes, threads, deep features, internal corners, and setup direction.
Burr, Deformation, and Heat Control
Thin walls, sharp edges, soft metals, hard alloys, heat buildup, and stress release are reviewed to reduce burrs, distortion, tool marks, and dimensional movement.
Surface Finish and Corrosion Protection
Anodizing, passivation, plating, black oxide, polishing, bead blasting, painting, and masking are matched to material, function, appearance, and corrosion exposure.
Inspection and Documentation
Critical dimensions, flatness, thread fit, hole position, mating surfaces, material records, and dimensional reports can be coordinated according to project requirements.

FAQ
Yes. If the drawing allows equivalent material, JADE-CNC can review available grades and confirm whether the substitute matches the functional and manufacturing requirement.
Tolerance depends on part size, material, geometry, setup, wall thickness, and inspection method. Critical tolerance zones should be marked clearly on the drawing.
Yes. Common options include anodizing, passivation, plating, black oxide, bead blasting, polishing, painting, and other finishes depending on material and application.
