Shenzhen Jingcheng Dingyi Forming Technology Co., Ltd. is one of the leading manufacturers and suppliers of cnc machine robot arm in China, specialized in providing high quality customized products. If you're going to buy bulk cheap cnc machine robot arm, welcome to get quotation from our factory. Quality products and low price are available.
Our CNC machined robot arms are built for accuracy, rigidity, and long-term stability. We machine complete arms and key components using 6061-T6, 7075-T6, stainless steel, and PEEK-depending on load, environment, and motion requirements. Critical tolerances go down to ±0.005mm for bearing positions, ensuring smooth movement and low backlash.
What matters in real use:
Light but rigid: Aluminum arms reduce weight by 30–40% without losing strength
High precision: Better alignment means less backlash and smoother motion
Material flexibility: 6061 for general use, 7075 for high load, stainless steel for harsh environments, PEEK for low-friction parts
Stable over time: Holds accuracy even after long cycles and repeated movement
Custom ready: Internal cable routing, mounting holes, and joint structures built to your design
How we make them:
5-axis CNC milling for complex shapes.
Precision turning for shafts and joints.
Then anodizing, passivation, or coating depending on the application.
These robot arms are used in industrial automation, cobots, humanoid robots, and medical systems. If a joint is off by even a small amount, the whole arm feels it. That's why we focus on alignment first, not just machining.
