Drilling a 0.1mm inner hole is a challenging task for carbide materials, here are some steps and suggestions:
1. Choose the right tools: Make sure you have the right carbide cold heading tools ready. Cold heading tools should have sufficient hardness and wear resistance to handle cemented carbide materials. 2. Preparation: Before starting cold heading, make sure to use a suitable cutting lubricant. This reduces friction and heat and provides better cutting conditions. 3. Determine the tool position: Depending on the required hole diameter, use a suitable drill or reamer to mark the position of the hole on the workpiece. 4. Prevent material movement: Carbide materials can generate high cutting forces, so proper clamping devices on the workpiece are required to prevent material movement
. 5. Start cold heading: Put the selected cold heading tool into the hole of the workpiece, apply appropriate axial pressure, and start cold heading. Make sure to maintain a steady cutting speed and proper lubricant supply. 6. Temperature control and cooling: Since the heat generated by the cold heading process may negatively affect the cemented carbide material, ensure that the tool and workpiece are controlled and cooled. Cooling liquid can be used for cooling. 7. Measurement and inspection: After the cold heading is completed, use a suitable measuring tool to measure the diameter of the hole to ensure that it meets the required size requirements.
