What is precision CNC machining?
CNC precision machining is computer numerical control precision machining, which includes lathes, milling machines, drilling machines, spark machines, wire cutting and so on. The most widely used are lathes and milling machines. CNC lathes can accurately process rotary parts, such as shafts, disks, etc., with high precision and high efficiency. It is widely used in the machinery manufacturing industry, such as the drive shaft in automobile manufacturing, the crankshaft of the engine, and various screw rods in daily hardware. The CNC milling machine can move the table or tool in multiple directions (such as X, Y, Z axis) to realize the processing of different parts of the workpiece, such as milling planes, grooves, gear profiles, complex surfaces, etc. Can process a variety of materials, including metal, plastic, wood, etc. For example, wings and fuselage structural parts in the aerospace field, injection molds in the mold industry, die casting molds and other complex shapes.

CNC turn-milling machining 2

CNC turning milling combination

Turning milling combination the machining functions of lathes and milling machines in one unit. Through one clamping, a variety of processing processes such as turning and milling can be completed at the same time. For example, when processing a complex rotary part, not only the outer circle and the inner hole can be turned, but also the plane, the keyway, the thread can be milling.

cnc milling machining

CNC milling

CNC milling removes materials from the workpiece to create custom-designed parts with flat surfaces using cutting tools or multi-point milling cutters. Milling cutter high-speed rotation, according to the program in the X, Y, Z axis direction cutting workpiece. It can accurately process planes, contours, grooves and other shapes with high accuracy, up to micron level.

cnc turning machining

CNC turning

CNC turning, which is mainly used to process rotary parts, is controlled by the computer to control the movement path of the lathe tool. The workpiece rotates, the tool moves axial and radial, and different shapes, such as shaft and disk parts, can be turned through precise programming. Its high precision, high efficiency, widely used in the field of machinery manufacturing.

Precision CNC Machining FAQs

The two primary CNC machining processes are CNC turning and CNC milling. Other machining processes include drilling, gear hobbing and electrical discharge machining,grinding among others.
Parts machined with metal will follow ISO 2768-m (medium) or ISO 2768-f (fine). Parts machined with plastics will follow 2768-m (medium). Geometric tolerances down to ± 0.001mm are possible but must be clearly indicated in technical drawings. We can achieve tighter tolerances on shafts with up to H7 fits with manual quoting and on occasion tighter.
We offer CNC milling (3-axis, 3+2-axis and 5-axis) and turning. Milled parts can be machined up to 2000 x 1500 x 300 mm for 3, 3+2 axis CNC milling. For 5-axis milling, the maximum part size is 650 x 650 x 300 mm. The maximum diameter for CNC turning is 431mm, length 990 mm. Minimum part dimensions recommended are around 2 x 2 x 2mm.The minimum for feature dimensions is 0.5 mm.

Minimum part dimensions recommended are around 2 x 2 x 2mm.The minimum for feature dimensions is 0.5 mm.
Deburing and edge breaking are standard procedures for all CNC machined parts. lf there are any critical edges that should be left sharp, they must be clearly indicated in technical drawings. Surfaces will be free of defects such as scratches, dents, stains, blemishes, hanging marks, minor defects. Surfaces indicated ascritical (primary (a) side, as indicated on the technical drawing) will be free of mill steps and other marks. For the secondary (b) side, minor hanging marks and up to 2 minor defects are acceptable. A number of post-processing and finishing methods can be applied to improve the surface roug hness, visual properties andwear resistance of machined parts.
We offer UNF, UNC, and metric threads for machining along with coil and key inserts. These are available on both milled or turned CNC parts.

Mastersdex caters to both one-off prototype and large-scale production runs. Thus, there is typically no strict MOQ. Whether you need a single part or thousands, Mastersdex aims to provide a solution.

Lead times can vary based on the complexity of the design, the chosen material, and the current workload. However, one of the advantages of CNC machining is its speed, especially for simpler parts. Once the setup is complete, machining times can be relatively quick. Parts machined as fast as 1 day! But for an accurate estimate, it’s best to request for quotes directly.
Product designers and engineers choose CNC machining to rapidly produce prototypes and production parts. The manufacturing technology offers a high level of precision, engineering-grade materials, quick-turn lead times.
Industries that use CNC machining include aerospace, automotive parts manufacturing, medical machine manufacturing, transportation, defense, and marine industries, along with oil and gas industries and electronics. CNC machining has allowed these industries to become more efficient at mass-producing custom CNC parts.
