EU Precision CNC Machining Services
Aria’s CNC precision machining services for engineers and procurement teams who need tight tolerances, reliable quality, and on-time delivery.
Aria Precision CNC Machining Services
A machining accuracy in the range of 0.01mm to 0.05mm is generally considered precision machining.
Precision CNC Milling Services
CNC milling uses rotating cutting tools to remove material from a stationary workpiece along multiple axes. It is the most versatile precision machining process, capable of producing flat surfaces, pockets, contours, and complex 3D geometries. 5-axis milling handles multi-face parts in a single setup, making it the preferred choice for complex aerospace and medical components.

Precision CNC Turning Services
CNC turning rotates the workpiece while a stationary cutting tool removes material along the outer or inner diameter. It is the go-to process for cylindrical components such as shafts, bushings, pins, and threaded parts, delivering superior diameter accuracy and surface finish compared to milling.

EDM Machining Services
EDM removes material through controlled electrical sparks between an electrode and the workpiece, with no cutting contact. It works on any electrically conductive material regardless of hardness, making it the only practical option for hardened tool steels, sharp internal corners, and intricate features that conventional cutting tools cannot reach.
Feature

EDM Types
Wire EDM, Sinker EDM, Hole Drilling EDM
Tolerance
0.005mm
Maximum Part Size
400×300×200 mm
Surface Finish
Ra 0.2 µm
Materials Capabilities
It is only applicable to conductive materials such as brass, copper, tool steel, titanium and stainless steel

CNC Grinding Services
CNC grinding uses an abrasive wheel to remove very small amounts of material, achieving tolerances and surface finishes that milling and turning cannot match. It is typically the final operation on precision parts requiring bearing fits, sealing surfaces, or post-heat-treat dimensional accuracy.
Feature
