- Q: How are the drills classified?
- As a result of structural reasons, the front angle is large at the outer edge and gradually decreases to the middle. The horizontal blade is a negative front angle (up to about 55 degrees), and plays a role of extrusion when drilling. In order to improve the cutting performance of the twist drill, the cutting parts can be cut into various shapes according to the nature of the material to be processed, such as group drills. Handle form twist drills with parallel shanks and taper shank two, when processing the former clamp the drill chuck, which is inserted in the machine tool spindle or the tailstock taper hole. Made of high speed steel for general twist drills. Inlaid with hard alloy blade or crown drill for machining cast iron, hardened steel and non-metallic materials, solid carbide twist drill used for machining small instrument parts and printed circuit board etc..
- Q: What drills are used in stainless steel drilling?
- We can also use stainless steel chip breaker, S carbide drill, four bit drill bit and indexable carbide drill.
- Q: How do the drills grind?
- The drill shaft is slanting out of the front angle.." Here is the relation between the axis of the drill bit and the surface of the wheel. "Frontal angle", that is, the vertex angle of 118 degrees + 2O half, about 60 degrees, this position is very important, directly affect the top of the drillAngle size and main cutting edge shape and cross edge angle. To remind students to remember a commonly used 30 degrees, 60 degrees, 90 degrees triangular plate angle of 60 degrees, students easy to master. A formula and formula two refers to the relative position of the grinding beforeThe two should take overall consideration, and don't neglect to set the oblique angle in order to settle the edge of the blade, or ignore the edge of the blade in order to set the oblique axis. These errors are often present in actual operations. At this point the drill is in the correct position
- Q: What's the difference between a twist drill and an impact drill?
- A twist drill is a tool for cutting round holes in a workpiece by rotating it in a relatively fixed axis. It is named because of its shape of spiral groove. The spiral groove has 2 grooves, 3 grooves or more grooves, but the 2 groove is the most common. The twist drill can be held in manual, electric, hand-held drilling tools, or drilling machines, milling machines, lathes and even machining centers. Drill materials are generally high speed tool steel or carbide.
- Q: What's the difference between full mill and rolling twist drill?
- A word is not clear, the different processing technology, the high production cost of drilling grinding, rolling and drilling cost is relatively low, also has the gap, drill grinding durability is more than fifty percent higher than in the rolling, and workpiece cutting performance, drill to drill a lot, I was the production
- Q: Small bit drilling, drilling machine speed is fast or slow?
- This size is easy to guarantee. A drill bit is to make two cutting edges for the small angle grinding symmetry, if you want to drill the round, can put some small angle grinding, namely some sharp, this bit in drilling, centering is better, the hole wall is relatively light.
- Q: How do you drill a sharpening bit?
- Grinding machine with a bit grinding, you can, our company is using the Muller machine drill grinding machine, grinding effect is very good.
- Q: I'm going to drill 10.5 of the thread. How many holes do I have to drill before tapping? How big is the tap?
- In the national standard, the first series of thread sizes are M10 and M12, so the 10.5 corresponds to the M12 thread. Check the screw pitch, diameter, bottom table, check the corresponding M12 bottom 10.25mm.
- Q: What causes the drill bit to break at the end of the hole?
- The cutting edge angle is not proper, and the iron chip blockage causes the resistance to increase.1) and the principle of uniform, when the edge angle is not appropriate, the drill operation must not only overcome the cutting resistance, but also overcome iron friction and pore wall blocking resistance, resistance and greater than two fold twist drill strength, also can cause the drill bit break.
- Q: How do the front and back angles of the drill change? How does it affect drilling?
- The front angle of the drill is the angle of the spiral groove of the drill. It is generally unchanged. After the drill angle should change according to the situation of the processing hole; for example, when drilling, the drill bit at the outer edge of the general angle generally between 8~14 degrees, if you want to draw it by fossa, orifice chamfering drill, drill angle will be smaller, the cutting edge of the drill will be down, like this helps maintain a steady state of the drill bit, rowed out nest and chamfer to smooth, does not produce the phenomenon of polygon.
