What is CNC turning?
CNC turning is a metal processing technology in today's manufacturing industry. It uses a numerical control system to accurately control the movement of machine tools, allowing large and complex parts to rotate at high speeds and cut them into precision parts with a tool.This technology has completely changed the traditional mechanical processing mode. Its core carrier CNC Turning Center has become the standard configuration of modern smart factories, and Precision CNC Turning has pushed the processing accuracy to the micron level.
1. Intelligent Innovation of CNC Turning Center
CNC Turning Center adopts a fully enclosed protection structure, equipped with an automatic tool changer and a precision spindle system, which can complete complex processes in an unattended state. Its core advantage is the linkage control capability of more than three axes. Through the coordinated movement of the X/Z/C axes, it can process rotating parts with special structures such as eccentric holes and spiral grooves. The advanced CNC system supports online measurement compensation function to correct the dimensional deviation caused by tool wear in real time.
Typical application cases include the machining of stepped holes in automobile transmission shafts. A single device can continuously complete 12 processes such as turning the outer circle, boring the inner hole, cutting grooves, and tapping threads, and the machining efficiency is 300% higher than that of traditional machine tools. A medical device company uses a CNC Turning Center equipped with a power turret to achieve a mirror effect with a surface roughness of Ra0.4μm in the machining of titanium alloy bone nails.
2. Precision breakthrough of Precision CNC Turning
Precision CNC turning can stably control the machining accuracy within ±0.002mm through constant temperature workshop environment control, hydrostatic guide technology and nano-resolution grating ruler. The spindle radial runout is less than 0.001mm, and the diamond tool can achieve ultra-precision machining of optical components. The roundness error of the inertial navigation system parts processed by a certain aerospace company using Precision CNC Turning technology does not exceed 0.0005mm.
3. Technical evolution direction of CNC turning
The composite machining turning center integrates milling and grinding functions to achieve complete processing of parts. The five-axis milling and turning compound machine tool can process special-shaped parts with spatial curved surfaces through B-axis swing. In terms of intelligent upgrades, the CNC Turning Center equipped with an AI visual system can automatically identify blank positioning errors and generate compensation processing programs in real time.
The cloud-based CNC system realizes remote monitoring and process optimization. A certain automobile parts factory connects 12 CNC Turning Centers through the Internet of Things, and the overall equipment efficiency (OEE) is increased to 85%. In terms of green manufacturing technology, the micro-quantity lubrication (MQL) system reduces the amount of cutting fluid by 90% and increases the tool life by 30%.
CNC turning technology is continuously evolving towards higher precision, stronger intelligence, and better energy efficiency. From the equipment upgrade of CNC Turning Center to the process breakthrough of Precision CNC Turning, this technology continues to break through the manufacturing limits and provide key manufacturing support for aerospace, new energy, biomedicine and other fields. Enterprises that master the core technology of CNC turning will occupy a strategic commanding height in the competition of high-end manufacturing.
