New Ideas for the Design of Shangao Tool Aluminum Alloy Special Drill
The cutting characteristics of aluminum alloy : lower strength and hardness than copper, good cutting process; easy to stick to the knife during processing, forming built-up edge; the structure is not dense enough, it is difficult to obtain a small surface roughness value; It is easy to cause deformation during processing, and the surface of the workpiece is also easy to be scratched or scratched; the coefficient of linear expansion is larger than that of copper, which affects dimensional accuracy. Compared with other difficult-to-machine materials, the processing efficiency is higher in actual production. Seco Tools is committed to developing high-efficiency cutting tools and providing low-cost machining solutions. Seco's Feedmax N is suitable for aluminum alloy processing. The Feedmax drills feature a unique N-slot design and DLC diamond-like coating technology that demonstrates superior performance when drilling low silicon aluminum alloys. The N-slot drill can greatly improve machining efficiency while maintaining good accuracy throughout the life cycle. The N-slot can be used to keep heat to a minimum to achieve good tool life and hole quality. It is characterized by the following features: 1 Cutting edge grinding: Processing these viscous materials requires a very sharp cutting edge. 2 Conical main back angle: The main rear corner is designed to be 12° to reduce contact with the workpiece material. 3 blade narrow: This unique N-slot design has a 40% narrower edge than conventional drills, which reduces the frictional heat generated between the hole and the drill during the cutting process to prevent the accumulation of heat. The tumor adheres to the bit of the drill bit. 4 inverted cone (axial back angle): the inverted cone is 0.5mm/100mm, which is twice the size of the standard hole, which can reduce the direct contact between the drill and the surface of the hole. 5DPC coating: A low friction coating designed to increase chip evacuation. This is the key to success. 6 Optimize the flutes: In order to achieve good chip evacuation, the flutes should be designed to be wider and deeper so that a larger amount of chips can be easily discharged. Thanks to the N-slot design and DLC coating, satisfactory results were obtained: 3600 holes were machined, the diameter deviation was 0.01 mm, the surface roughness value R a was within 0.1 μm, and the cutting edge was still intact.
