Introduction: Thermal Drilling Technology for Sheet Metal Drilling & Tapping
What is Thermal Drilling: Making Holes without Removing Material
Thermal Drilling Process:
Formdrill® tools are made from Tungsten Carbide. Their conical body has specially developed lobed geometry. Thermal drilling process is a method of making a hole and simultaneously producing a bush from the parent metal to give additional support as a bearing surface or for a thread.
Make a hole and form a bush in one operation.Frictional heat is generated by speed and pressure to form the material.Fast cycles(2-4 sec for M8-M10 holes
The completed bush gives additonal support as a bearing for a thread.Threads are produced by roll forming. No material is removed.Strong connection with no parts to break free improves joint connection.
Advantages of Thermal Drilling Process:
| Versatile | Useful for malleable material – mild steel, stainless steel, copper, aluminum, etc. Useful for Tubes, Pipes, Angles, Channels, Flats of wall thickness 1-10 mm (M.S.) |
| Fast | Increase Production with Faster Cycle Time: M8-M10 holes within 2-4 seconds |
| Strong | Improvement in quality by creating stronger joints having pull out strength greater than DIN Standard for Welded Nut |
| Secure | No inserts to break free Cleaner Working Environment due to Chip-less Process |
| Cost | Eliminates usage of welded nuts, threaded inserts thereby reducing cost |
| Easy to Use | Easy to UseCan be used with any good quality Pillar Drill, CNC Drilling, Precision Milling, CNC Machining Center, with good spindle bearings, adequate spindle speed and power. |
