Drill bit chipbreaker grinding method? How does an ordinary drill grind a chip breaker? 20 or so dri

1. Prepare the diamond.

It is specially used to repair the grinding wheel, which is convenient for us to choose the use of the grinding wheel thickness. It can be distinguished by points and surfaces, and the cylinder diamond pen is selected, and the grinding wheel is better used.

2. Recognize the grinder in the grinding wheel room.

The switch button to stop the red light and the green light line. For safety reasons, it is necessary to respond quickly and choose the right one in an emergency. If a fast-rotating grinding wheel is not used correctly, there is a possibility of wheel breakage, so the simpler it is, the more cautious it is.

3. When the grinding wheel is seriously worn, try to replace the grinding wheel, so that the new grinding wheel will not be laborious.

4. Grind the cutting edge of the drill bit, first repair the grinding wheel surface with a diamond pen, and the drill bit will not bounce when pasted, which has a very stable feeling. To polish better, the grinding wheel needs to be repaired more finely.

5. After the transverse blades on both sides are grinded, the edge grooves are combed through the edges and corners, and the tip of the drill bit used for centering should not be too large.

6. If the drill bit is ground evenly on both sides, the force will be uniform and it can be used longer. The cutting edge that needs to be used needs to be grinded, and the standard drill bits are the same, and they are resharpened according to the actual needs when they are used in different places.

7. Grinding drill bit, good looking and easy to use, finish.

Well, flat, is the best effect. In fact, the most important thing is that the material of the drill bit itself is better, and it can be properly reground according to its own needs in order to meet the requirements of use.

When the twist drill is sharpened, the top angle of the drill bit is larger than that of the drill bit of ordinary materials (between 130 and 135 degrees), and the large hole diameter needs to be drilled first with a small hole and coolant at the same time.

To be sufficient, the cutting speed should not be too fast, and the feed should not be greater than, and the cutting speed and feed can be flexibly selected according to the size of the hole diameter to reduce the cutting temperature.

1. Choose the right grinding head: Choosing the right grinding head is the key to grinding the drill bit to achieve automatic chip breaking, generally speaking, the grinding tip of the grinding head should be sharp, and the angle of the grinding knife should also be correct, so as to ensure that the grinding drill bit can better grasp the material, and then achieve the effect of chip breaking. 2. Set appropriate grinding parameters

In the grinding process of the grinding bit, the setting of parameters is also very important, generally speaking, the speed of the grinding head should be controlled as low as possible, and the feed speed should be slow enough, so as to ensure that the grinding knife can have enough time to touch the material, effectively grasp the material, so as to achieve the effect of automatic chip breaking. 3. Abrasives and other materials are carefully selected: the choice of abrasives is also the key to determining whether the grinding drill bit can achieve automatic chip breaking, generally speaking, the particle size of the abrasive should be selected as fine as possible, and the abrasive that can effectively grasp the material should be selected, so as to achieve the effect of automatic chip breaking.

Steps to grind and sharpen the drill bit:

Holding the drill bit in hand, the axis of the drill bit is about 15 angles to the left of the grinding wheel side in the horizontal plane, and the radius of the grinding wheel at the grinding point in the vertical plane is about 55 swing angles.

During sharpening, the grinding point on the drill bit gradually moves from the back of the outside edge to the drill core, ensuring the bevel angle of the inside edge and the rake angle of the inside edge. The grinding amount is from large to small, and the pressure should be light when grinding to the drill core to prevent the cutting edge from annealing.

The drill core should not be ground too thin, the bevel angle of the two inner edges should be the same, and be careful not to damage the outer straight edge and the rounded edge.

If you hit thick things, use the drill bit in an ordinary way, such as hitting thin things, you can grind the drill bit into the "Ni Zhifu" type.

When the drill bit is sharpened, the rear angle is a little smaller, not too sharp

But this is a waste of drills!

Not recommended

Dear, you have a good reputation! We're happy to answer for you! To make it easier to break chips with drill bits, here are some suggestions:

1.Use the right grinding tool: Choose the right tool for drill grinding, such as a grinding stone, grinding wheel, or sandpaper.

Different drill bits may require different types of tools. 2.Choose the right grinding speed:

Make sure that the grinding speed is moderate, too high or too low speed can lead to poor results. Depending on the material and hardness of the drill, the grinding speed is adjusted to achieve the best results. 3.

Ensure uniform grinding: Maintain uniform force and angle when grinding the drill. Avoid over-grinding or uneven grinding, which can lead to poor chip breakage of the buried drill bit.

4.Use coolant: During the grinding process, use the right amount of coolant, such as water or cutting fluid, to avoid overheating.

Overheating may result in a soft drill bit and poor chip breaking. 5.Clean the grinding surface regularly:

Metal shavings and grinding powders are generated during grinding, and the surface is cleaned regularly to ensure smooth and accurate grinding. Please note that the above recommendations are general guidance and may need to be adjusted on a case-by-case basis. In addition, the quality of the drill head and the design of the cutter will also affect the chip breakage, and choosing a high-quality drill bit may have better results.

Summary. Deep hole drill bits require coolant to cool and lubricate during use to help remove chips. However, if the chips clog the drill bit and prevent the normal flow of coolant, then the deep hole drill bit will be damaged and the drill bit will wear out and heat up, creating dangerous chip breaking.

Therefore, grinding chips is one of the key factors to ensure the proper operation of deep hole drill bits. Here are a few common ways to grind chips:1

High-pressure coolant and air injectors are used, e.g. G&D nozzles and high-pressure pure water cooling systems for deep hole drilling. This method produces enough cooling and lubrication for smooth removal of chips. 2.

Detergents and lubricants are used and injected into the borehole so that the chips are mixed with liquids and greases to make them become.
