I have only used a grinding wheel to grind, or tool grinding, and I have never heard of angle grinding, but it is really amazing to be able to grind angle grinding and grinding drill bits.

<> "1. How to use an angle grinder.

1. Before use, you should check in detail whether the grinding disc and protective cover are installed firmly. If the grinding wheel is already broken, it must be thrown away and cannot be used again, otherwise it will cause damage to the construction surface. In the process of cutting, it is necessary to prevent sparks from splashing, if you accidentally splash on others, or splash on the items that are easy to burn, it will cause potential safety hazards.

2. When the angle grinder has just started, the float will be larger, and you should use both hands to hold the handle firmly. When the rotation of the grinding wheel becomes stable, the construction can begin. When using an angle grinder for cutting or grinding, be sure to grasp the handle firmly and use even force.

Second, what are the key points of use of angle grinder.

1. During use, be sure to grasp the handle of the angle grinder with your hands, if you do not catch it, the angle grinder will form a moment bucket hail when it rotates, causing damage to the angle grinder or the human body. In order to ensure safe use, the angle grinder must be equipped with a protective cover, and if it is not configured, it cannot be used.

2. During use, the human body should not stand in the direction where debris will fly out, otherwise when the debris flies out, it will cause damage to the eyes of the human body. To avoid eye injury, it is best to wear eyepieces when using them.

3. When you don't need to use the empty sail angle grinder, you must cut off the power supply in time, and you should put it down gently, not too strongly, and at the same time you should put it in a proper place, and you should never throw it away or put it indiscriminately, or smash it to the ground.

Friends who appreciate the stone and play with the stone are more and more, sigh that the magic of nature has the effect of self-cultivation at the same time, it is one of the wonderful methods of taking quiet in the city, the good rough stone has just been unearthed, and the proper treatment will directly affect its final presentation effect. Due to the different characteristics of various stones, the treatment methods of rough stones are not exactly the same, but grinding and polishing are two essential steps.

Tools Raw materials.

Angle grinder, tooth machine, all kinds of grinding heads.

The original stone that has just been unearthed will generally be covered with soil, especially the deeper stone lines are filled with dirt, many of which are tightly bonded with the original stone, if they are removed by brute force, they will hurt the stone and even destroy the original shape of the stone.

Therefore, before the rough stone is treated, it should be first put into the bucket and soaked for two or three days, so that the floating soil can be fully dissolved, the rough stone absorbs enough water, and the adhesion of the attachments on the surface of the rough stone is loosened.

After the rough stone is soaked through, the rough stone is cleaned with a steel brush dipped in water, and the work of removing floating soil is preliminarily completed. It is recommended to prepare a few more steel brushes of different specifications, and the appropriate brush surface will achieve twice the result with half the effort when cleaning different stone surfaces, stone seams, and textures.

After removing the floating soil with a steel brush, then use a hand grinder tooth machine for more detailed grinding, the grinding head specifications should be from coarse to fine, for the stone with more textures, the impurities in the texture should be patiently polished clean by the fine grinding head to ensure that the stone surface is clean and smooth. This step is the most patient, there is no obvious treatment effect when removing the floating soil, and the sense of achievement will be relatively low, but this step is the key step to determine the final treatment effect of the stone, do not be impatient and lazy.

After grinding with a grinding machine, depending on the depth of the grinding marks on the stone surface, sandpaper from 600 mesh to 2000 mesh is selected for the final fine grinding treatment in turn.

After the polishing is completed, the stone surface should be very smooth, there will be no concave and convex sensation to touch, and there are no obvious scratches in the light.

Finally, you can enjoy our play stone with full of achievements, after polishing and polishing the stone, the surface will appear jade luster, reflective effect, really pleasing to the eye, if the original stone is photographed, at this time to compare, when there is a sense of chrysalis into a butterfly.

The correct way to grind the drill bit is as follows:1. First of all, remove the drill bit from the drill chuck, do not take the pistol drill and grind the drill bit together.

2. Hold the top part of the drill bit with your right hand and the tail of the drill bit with your left hand.

3. Make the top knife edge of the drill parallel to the grinding wheel of the grinder, and then grind against the grinding wheel.

4. When grinding, keep the position of the drill bit with the right hand, and move the tail of the drill slightly up and down with the left hand.

5. Grind one side of the knife edge, and then rotate 18 degrees to grind the knife edge on the other side.

Before grinding the drill bit, the main cutting edge of the drill bit and the grinding wheel face should be placed on a horizontal plane, that is, the entire cutting edge should be ground when the cutting edge touches the grinding wheel surface. This is the first step in the relative position of the drill bit and the grinding wheel, and then slowly lean against the grinding wheel face after the position is placed.

It will directly affect the size of the drill tip angle and the shape of the main cutting edge and the bevel angle of the cross edge. This refers to the position relationship between the drill bit axis line and the grinding wheel surface, which is 60°. Here we should pay attention to the relative horizontal position and angle position of the drill bit before grinding, and the two should be taken into account, and do not ignore the angle of the angle in order to level the cutting edge.

After the cutting edge touches the grinding wheel, it is ground from the main cutting edge to the back, that is, from the cutting edge of the drill bit, first touching the grinding wheel, and then slowly grinding down along the entire flank face. The drill bit can be cut in with a slight touch of the grinding wheel, and a small amount of sharpening can be performed first. And pay attention to observe the uniformity of the spark, adjust the pressure on the hand in time, and pay attention to the cooling of the drill bit, so that it can not be ground overfired, resulting in discoloration of the cutting edge, and annealing of the cutting edge.

The main cutting edge should swing up and down on the grinding wheel, that is, the hand holding the front of the drill bit should evenly swing the drill bit up and down on the grinding wheel surface. However, the hand holding the handle can not swing, and the back handle should be prevented from being upturned, that is, the tail of the drill bit cannot be raised above the horizontal centerline of the grinding wheel, otherwise the cutting edge will be dull and unable to cut.

Dear, first remove the drill bit from the drill chuck. This is much more convenient when grinding, and it is also the correct operating procedure. It is not advisable to take a pistol drill and grind the drill bit together.

The drill bit is to be ground in the upper part of the grinder. When grinding, make the knife edge of the drill parallel to the grinding wheel of the grinder, and then grind against the grinding wheel. It is generally recommended to hold the right hand at the end of the working part of the drill bit and the tail of the drill bit with the left hand.

When grinding, keep the position of the drill bit with the right hand, and move the tail of the drill slightly up and down with the left hand, paying attention to the movement range not exceeding the height of the drill bit.

Be careful not to rotate the drill bit during the grinding process, sharpen one side of the knife edge and then rotate 180 degrees to grind the other side of the knife edge. Finally, the knife edge grinding is changed repeatedly. After the two knife edges are sharpened, the transverse edge can be sharpened.

The method is to grind the middle one on both sides into a pointed end. The specific form is the same as the center hole. In this way, the drill bit is rounded when processing some thin iron plates.

Questions. The water drill bit is not sharp in use, what to grind.

Okay dear, wait a minute.

Rhinestone drill bit does not need to be polished, the cutting part of the rhinestone bit is diamond, in the drilling process, the diamond particles play a cutting role, the hardness of the adhesive is less than that of diamond, and it is constantly worn out, so that the new diamond particles are constantly exposed, and the drilling and cutting can be carried out, as long as there are diamond particles, if there are no diamond particles, then it can not be used.

Questions. Don't grind and don't move.

Yes, because he's very hard, oh diamond,

In the process of machining with a drill bit, if the drill bit is unfortunately broken or dulled, our usual treatment method is to sharpen or chamfer the drill bit. Among them, grinding chamfer drill bit is a very common treatment, and we will introduce the correct operation steps of this method in detail below.

Preparation. Before grinding a chamfer drill bit, you need to prepare some essential tools, including:

1.Hand drill.

2.Drilling chucks.

3.Grinders.

4.The right whetstone.

5.Long-necked lamps and other lighting equipment.

In addition, for drill bits of different diameters, it is necessary to choose grinding wheels and whetstones of different thicknesses to ensure that the drill bits after grinding sensitive chamfering can achieve the best results.

Procedure. 1.Clamp the drill bit in the drilling chuck, and after fixing, you can rotate the drill bit by hand to see if there is any obvious distortion or deformation. If there is a problem, you need to dispose of the drill bit before grinding the chamfer.

2.Use a grinder to trim the drill bit so that it is straight, and the grinding wheel should be accurately aligned with the drill bit. Note that the speed of the grinding wheel should be moderate, too high or too low will have a negative effect on the drill bit.

3.Start grinding the chamfer, place the whetstone on the grinder, and slowly touch the drill bit to the whetstone, so that the blade is rubbed to achieve the purpose of grinding off the cutting edge. It is best to rotate the drill bit to facilitate the uniformity of grinding chamfers and the viewing of the effect.

4.Constantly change directions and grind all the positions on the whetstone until the desired chamfer effect is achieved.

5.After grinding the chamfer, rotate the drill bit by hand to check the uniformity of all cutting edges and whether there are any residual burrs.

Precautions. 1.Be sure to choose the right grinding wheel and whetstone, the thickness of the grinding wheel and the material of the whetstone will have a direct impact on the effect of grinding chamfering.

2.For smaller drill bits, you need to be more patient and careful, otherwise it is easy to grind the drill bit off or damage it in the process of grinding chamfering.

3.In the process of grinding chamfering, do not overgrind off the cutting edge of the drill bit, pay attention to keep the angle appropriate, so as to avoid affecting the effect of the drill bit.

Through the correct grinding and chamfering method, the life of the drill bit can be extended, its processing efficiency and quality can be improved, and it will provide a stronger guarantee for our processing work.
