The textured surface of an Instrument Micro Screws enhances friction at the contact point
2026,04,01
The contact surface between the
Instrument Micro Screws and the workpiece is a crucial point for preventing slippage. Smooth surfaces are prone to slippage due to oil stains and elastic deformation, necessitating texture design to increase the coefficient of friction.
Texture type selection: Depending on the workpiece material characteristics, common textures include diamond-shaped knurling, straight knurling, or dotted pits.
For example, for high-hardness cold-rolled steel sheets, a diamond-shaped knurling with a depth of 0.3-0.5mm (2-3mm spacing) is used to enhance friction without excessively damaging the workpiece surface.
For soft aluminum profiles, shallow dotted pits of 0.1-0.2mm are used to prevent scratches during stretching.
Texture processing technology: Laser engraving or electrical discharge machining (EDM) is used to ensure uniform and durable textures.
Laser engraving offers high precision and is suitable for creating textures on complex curved surfaces; EDM is suitable for hard Instrument
Micro Screws steel and can create wear-resistant textures with consistent depth.
One case shows that when a company was stretching stainless steel tableware, the slippage rate of the workpiece reached 15% due to the smooth surface of the punch. After improving the diamond mesh pattern, the slippage rate dropped to less than 1%, and the accident rate decreased by 92%.
