For example, a user has been machining a cylinder crankcase of AlSi material with a M8 PCD tapped hole drill for more than a year. Previously, when machining with a solid carbide tapped hole drill, a tool change was required for every 15,000 threads processed. The HP-Tap Drill drill is now machined at 875r/min spindle speed and 1250mm/min feed rate. After cutting more than 350,000 threads, the drill bit still shows no signs of wear, which means the tool life is increased by 22 Times.
Another user also used the HP-TapDrill bit for the M8 and M10 threads of the AlSi cylinder crankcase. Previously, only 20 workpieces could be machined with a normal screw hole drill, and the HP-TapDrill drill can continue to be used after more than 300 workpieces and 11,000 threads have been machined, and the tool has no signs of wear. Good surface quality and dimensional stability. In addition to significantly increasing tool life, the HP-TapDrill bit reduces machining time by 60%.
Diamond Wire For Silicon Cutting
The advantages of Diamond Wire cutting technology are huge, and it can replace the traditional mortar wire. Diamond wire is mainly used in the cutting of hard and brittle materials such as crystalline silicon and sapphire. Compared with traditional mortar steel wire cutting, it has high efficiency (4-5 times the cutting speed), less loss and high chip yield (15-20% more silicon). The advantages of low environmental pollution (no organic liquid) and high product quality. Among the diamond wire, electroplated diamond wire is widely favored by the market for its outstanding advantages of low wire consumption per piece, small wire diameter and high cutting efficiency, and is superior to resin diamond wire.
