M8 Ball Head Hand Tightened CNC Hardware Parts Nut Non Standard Custom Machined

The high toughness and low thermal conductivity of stainless steel (such as 304 and 316) lead to three major problems: frequent occurrence of tool adhesion and built-up edge, which damages the surface roughness of the sphere (Ra needs to be ≤ 0.8 μm); the cutting temperature exceeds 800°C, causing thermal deformation of the workpiece, affecting the sphericity (tolerance ≤ 0.01mm) and positional accuracy (≤ 0.02mm); the hardened layer hardness reaches HB300 or above, intensifying abrasive wear of the tool, and reducing efficiency by 30%.

Small nuts require fine-diameter tools (≤5mm), which have insufficient rigidity and are prone to vibration. The spherical closed space makes chip removal difficult, and cooling and lubrication are uneven, which aggravates tool sticking and wear.

We have introduced advanced equipment and technology from Japan and Germany (CNC 5-axis and 6-axis machines) to better serve our customers' needs.

Our maximum processing outer diameter is 60, and the minimum control tolerance is 0.001. We have Japanese CNC Tsugami, CNC Citizen, multi-station cold extrusion forming machines, 500T press machines, casting equipment, and various process equipment, which can effectively provide customers with the best technical solutions.
