What’s Precision Custom CNC Machining Services China
Precision custom CNC machining services China is a high-accuracy manufacturing process focused on producing parts with strict tolerances and high precision requirements. This service encompasses various machining methods, including:
Turning: A process where a workpiece is rotated while a single-point cutting tool moves along its axis, ideal for creating cylindrical parts. Turning can accomplish external and internal circles, end faces, and threading. Commonly used for manufacturing sleeves, shafts, accessories, manifolds, gaskets, and similar items.
Milling: Milling uses a rotating multi-toothed cutter to machine a workpiece, capable of producing flat surfaces, grooves, gears, and other complex-shaped parts. The process is versatile and can handle a variety of spatial structures.
Difference Between Precision CNC Machining Services China and Large Machining
Precision CNC machining services China is focused on the processing of high precision and intricate details, while large-scale CNC machining caters to the efficient processing of large-sized workpieces. Each plays a critical and unique role within the manufacturing industry.

Facilities
In the CNC machining services China, the distinction between precision CNC machining and large-scale CNC machining is pronounced, particularly in terms of eqConuipment used, machining accuracy, and application fields. Precision CNC machining typically involves smaller machines such as lathes, milling machines, and compact 5-axis machining centers with worktable sizes generally under 1000mm nominal size. These machines are capable of achieving high precision levels, often reaching IT7 to IT5 grades, with surface roughness as low as Rα0.04μm (0.01μm), a finish sometimes referred to as “mirror turning.”
Accuracy
On the other hand, large-scale CNC machining employs heavy-duty equipment like large gantry milling machines, capable of handling workpieces that exceed 1000mm in size. The precision of these large-scale operations typically falls within IT8 to IT6 levels, with surface roughness ranging from Rα2.5 to 0.16μm. Due to their structure and scale, large CNC machines are more suited for processing sizable components, such as in mold manufacturing and large mechanical structures.
