Basic knowledge of diamond grinding wheel

classification of 1. commonly used grinding wheel:

1)M: Bronze wheel (Metel), main cutting;

2)R: Resin wheel (Resindiamond) Zhuhai Jinyang, Italy Belfore, DIA, ADI, Vincent,WINTER, etc;

3)P: fine grinding wheel (Polishing) Italy RBM or Germany ARTIFEX 10S40,BK46,BK60,BK80,BK120,AO60;

4)P-c: with polishing powder wheel (PolishingwithCeO2) Italy RBM or Germany ARTIFEX X5000,X3000,X081,CE-3;

5)F: Felt wheel (Felt);

6)E: straight line straight edge (Flatedge);

7)B: Bevel;

8)S: Straight chamfer (Flatseams);

9)Pe: straight line periphery (Peripheral).

10)BD peripheral polishing mud wheel;

2. the standard scale key of the commonly used cup wheel and bowl wheel grinding wheel, and the benchmark of concentricity and flatness positioning:

It is mainly to sort out the radial and end face runout (how to check the radial and end face runout of the grinding wheel of the bevel machine);

Contact between 3. grinding wheel or drill bit and grinding head spindle rolling speed:

1. The larger the diameter of the grinding wheel ring, the faster the linear speed of the grinding head spindle together. When necessary, the rotating speed of the grinding head should be adjusted according to the diameter of things (such as FLZ25 vertical drill and various drilling machines),

2, or choose different types of motors to use with grinding wheels (for example, X5000 polishing wheels are 2840RPM for grade 2 motors and 1420RPM for grade 4 motors with 380V50HZ, but 3400RPM for grade 2 motors and 1700RPM for grade 4 motors with 380V60HZ power supply in South Korea and the United States; (Pay attention to whether the polishing of both sides of the company and the grinding head speed of safe chamfering meet the requirements;

4. grinding machine is to use the grinding wheel for cold processing of glass, grinding wheel number or mesh number is larger, grinding wheel abrasive particle size is finer, the weaker the grinding force:

For example, the FXM371 and FZM9325 grinding wheels are equipped and the distribution of grinding volume:

5. the steering requirements of the grinding wheel and the requirements of the grinding wheel on the water spray direction of the cooling water spray pipe and the direction of the fastening screw teeth due to different steering.

1. The contact between the rolling direction of the grinding wheel and the forward direction of the glass (generally opposite to the bite contact), but the machinery in use avoids water channeling and leakage, and sometimes puts forward the opposite requirements for steering);

2. Orientation of the nozzle (when there are two water pipes, one is aligned with the center of the grinding wheel and the other is along the direction of rotation of the grinding wheel)

3. When the grinding wheel rotates, the right tooth screw must be specially tightened (FXM351 wool wheel polishing), or the reverse tooth screw (YM7 linear round edge machine)

Diamond grinding wheels sintered 6. metal alloys are commonly known as diamond wheels: the diamond-containing part of the diamond wheel is called the working layer, and the working layer is mostly in the shape of a ring, so it is also called the working ring. The height of the working ring is called the working height, the working width is called the ring width, the outer part of the ring width is called the outer ring, and the inner part is called the inner ring. The diameter of diamond particles is commonly known as particle size or mesh. The round edge of the working ring can contact the glass twice. The working ring contacted first is the front ring, and the working ring contacted later is called the back ring. The width ground after glass cutting is commonly known as the machining allowance.

The Matching Skills and Debugging of 7. Grinding Wheel

1, replace the grinding wheel should choose the original standard, for example, the 150 diameter can not 175 the diameter of the grinding wheel exchange

2, select high-function grinding wheel, 1,2,3 function should be common, concave and convex grade distribution will have bottleneck effect.

3. The grain size of the grinding wheel is reasonable. In principle, the overall efficiency should be guaranteed. The latter level should be able to correct the chipped edge grinding marks of the previous level and keep approaching the bright light.

4, distribution can not only rely on ammeter swing or noise size and other experience debugging, should often back out of the glass to check the wear marks. The margin ratio of No. 1,2 and 3 should be close to 7.5: the grinding amount of No. 2:0.52 should be controlled within 1mm.

5. The grinding wheel should try its best to choose the front and rear ring operation method (that is, the swing angle of the grinding wheel). The processing ratio of the front and rear rings is close to 8:2. The grinding amount of the rear ring should not be too large. The grinding marks of the front ring should be evenly and finely covered. The front and rear rings of the grinding wheel are in opposite directions. The end face shape should maintain the factory shape and viewpoint when the grinding wheel is consumed.
