1.5 drill hole diameter in the diameter of 3.2MM copper to what the knife?Someone told me to use white Gangdao, is said to be very difficult to grind? Is there no one understand this? There is no automatic sharpening machine this knife?In the bar diameter 3.2MM two M2 drill hole, need to use what tool?
Do you know how deep holes you have to make?In fact, we can let professional punching company do it.1 、 small hole processing of sheet metalFeatures: high drilling accuracy, smooth hole, straight hole.Aperture: 0.005mm or morePlate thickness: 0.01mm to 0.3mmPore diameter and thickness ratio: 1:1.5 ~ 3Hole spacing accuracy: 100mm interval, less than 0.02mm.Material: nickel, copper
Bar diameter is small, relatively speaking, the hole is large, must be two times the first with a small diameter drill, drill, and drill reaming is reliable, can refer to the 2 floor of the situation
You can do a special clamping the first fixed copper after drilling speed control in 1200~1400 if a large amount of words. But the main problem is tapping, when tapping can use the same fixture, with mechanical tapping, manual, began to build teeth feel bad. When tapping, you can add some kerosene.
White steel knife? Do you want to drill holes? Of course, with drill bits, I don't know whether the copper pieces you want to process are copper or brass, the copper bit has the grinding method of the copper, and the brass drill has the grinding method of the brass bit. If the small batch does not matter, ordinary drill on the line, and if large quantities, it is necessary to grind a special shape of the drill bit, plus cooling diamond, because copper hardness is small, as long as the heat, grinding a drill bit can be used for a long time. I can send you the drawing of the drill bit if you need it
