What is CNC turning?


CNC turning is mainly for some round or spherical parts, internal and external conical holes, and special internal and external threads, also available for drilling and knurling. The precision can be 0.005mm, follow to the surface roughness ISO 2632/1-1975 standards. Both engineering plastic and metal can be optional. Such as stainless steel, low carbon steel, copper, aluminum alloy, magnesium alloy, PEEK POM PA ABS PP PC PMMA PTFE.


Advantages of CNC Turning

  • 1.Fast finish for round, spherical, shaft, conical parts.

  • 2.Simple programming, just enter the G code parameters.

  • 3.MOQ only one piece for customized part. Also available for mass production.

  • 4.Cost saving and high efficiency.

  • 5.High precision to 0.005mm. Surface roughness standards ISO 2632/1-1975.

  • 6.Non-standard thread machining. eg. M3*70 pipe threading, conical threading, lens threading, special internal and external threading.

  • 7.Various material: Stainless steel, low-carbon steel, copper, aluminum alloy, magnesium alloy, PEEK, POM, PA, ABS, PP, PC, PMMA, PTEF and so on.

  • 8.Compared with CNC milling, it is more round and accuracy in round and spherical shape.

CNC Turning Classification


  • Hard turning – A process designed to replace grinding processes used for hardening materials.

  • Grooving and end grooving – The process of cutting slots of predetermined depth to the side or face of the workpiece.

  • Drilling – Mainly used to remove materials from the workpiece from the inside. More advanced CNC lathes can stop the workpiece rotation, drilling or milling away from the center or cross center to the workpiece.

  • Boring – The process of expanding pre-drilling with a single point tool.

  • Reaming – The process of expanding pre-drilling with a multi-groove tool designed to cut tool diameters.

Difference between turning and milling

1.Different machining method

Generally, Turning machining is special for round, shafts, sleeves, disks, cushions parts. Mainly is horizontal machining. Also large lathe is vertical and other machining forms. There are usually a cutter holder to fix the cutter. And machining form is generally the cutter feeds automatically. Mainly movement is the part rotating.

CNC Turning available for internal holes, threads, and knurling machining (low-speed machining). Also it can be solved with complex rotary ball-shape or round shape feature machining.

Milling machining, machining method is opposite from CNC turning. The main movement is the cutter rotation, while the part is feeds movement. Milling is to fix the blank(rough material) with a high-speed rotating milling cutter to move on the blank(rough material) to cut out the required shapes and features. Traditional milling is common used to simple shapes/features, such as profile and grooves. CNC milling machine can process complex shapes and features.

2.Different (structure) parts.

Turning machining is processing the rotating parts (round shape). Clamped the parts on the main shaft by a three-jaw chuck and rotating with high speed. Then, use a turning cutter to move around the busbar to cut out the part profiles. CNC Turning available for internal holes, threading, and knurling machining (low-speed machining). Also it can be solved with complex rotary ball-shape or round shape feature machining.

Milling machining is fixed the blank(rough material), and with a high-speed rotating milling cutter to move on the blank(rough material) to cut out the required shapes and features. Traditional milling is common used to simple shapes/features, such as profile and grooves. CNC milling machine can process complex shapes and features.
Simply speaking, Turning is moving parts with fixed cutter, while Milling is moving cutter with fixed parts.
