How to avoid the cutting process burns
The question now is how to avoid burns during cutting , the low cutting efficiency.
The first is whether the choice of wheel hardness is too high or too bottom , should burn microstructure appears too high , can not accurately test the organizational structure of material errors. Should the hardness appears over the bottom end of the cutting efficiency , waste cutting disc . How can the cutting process does not burn and sharp, the diamond blades hardness of the material needs to be used correctly detected , and the cooling fluid.
Followed by the selection of cutting slices of raw materials , alumina material of choice for cutting metal materials , cutting non-ferrous metals and non-metallic materials of choice for silicon carbide material. Because the cutting metal material with no chemical reaction with the metal alumina material chemical composition, facilitates the cut . Non-metallic and non-ferrous metal chemical activity of small, silicon carbide material itself chemically active than the alumina , better cutting performance , small burns , wear and small .
Once again, the particle size , particle size selection in favor of a moderate cut . If the request should use dry cut blades sharp coarse granularity. If you require high precision cutting , partial fine granularity should be used abrasive .
In short , the problem of the cutting process in metallurgical samples to the hardness of the material before and determined in the selection of cut pieces . In the selection of the targeted cut sheet material. Unlike ordinary metallurgical cutting metal cutting , common metal not require more than you can burn off just durable resin grinding wheel cutting disc quality analysis resin grinding wheel cutting disc with ceramic small wheel , super oil stone , plated grinding wheels, abrasive resin ( superhard and Cape mill ) products, suitable for business investment , marketing is not difficult , most can be said cottage , less investment , less employment , small footprint, simple process , which produces high- quality products with stable quality there are some difficulties, only regular visits to customers , invested research and development of new products , a lot to learn advanced technology to the workshop to develop into a real business.
( 1 ) Abrasive material: Common abrasive cutting wheels have cut brown jade (A), white fused alumina (wA), black corundum (BA), silicon carbide (c) , the most commonly used is corundum, corundum hardness because high , high toughness and shape , applicability and low price compared to other abrasive characteristics . Corundum their reduction in the adequacy of primary smelting and secondary sand sand , mainly in the chemical composition : Al2O3 content level sands ≥ 94.5; Al2O3 content of 94.5% of secondary sand ; generally around 85% and Fe2O3 content of 4-5% ; therefore stone polishing pads lower than the hardness of the secondary level sand sand , but the price is also low ; corundum for a variety of carbon and alloy steel processing in general ; higher than white fused corundum hardness, brittleness large , grinding heat is small, because the price is high , the thermal deformation of the workpiece requires hours , and it also has a special material is used as an abrasive mix processing ; Al2O3 corundum content in the 70 ~ 85%, Fe203 content of 7-9 %. low hardness , cutting forces poor, but the price is cheap ; tall black silicon carbide hardness and brittleness good , sharp cutting edge , good self-sharpening properties, good thermal conductivity, have an advantage in terms of processing non-ferrous metals , plastics , rubber and cast iron .
2 ) Abrasive Grit: Common particle size : 22 # -80 # , fine granularity low cutting efficiency.
3 ) Wheel hardness: Hardness used : P, Q, R; N, S; hard wheel generally used to reduce grinding wheel wear. The hardness number of the binding agent , the density of the molding , sintering temperature and sintering time were controlled .
( 4 ) binders:
( 5 ) Organizations: cutting wheels should be slightly larger number of organizations to improve cutting efficiency : too much strength and influence , often organized No. 3 to 7 . Forming firing ( also called hardening ) the impact of technology on the cutting performance :
( 1 ) Molding are: hot , cold, rolled three methods. Thermoforming method required little pressure. Cutting sheet molding density, high hardness , strength ; multi-purpose hot pressing in northern China ; advantage of cold pressing method is that when the heat source is not required for grinding various binding agents ; multi-purpose cold southern China Law ; rolling law required energy is small, small molding density, low efficiency , are less common . Generally without enhanced network has thin wheel and export resin piece wheel with Bo .

single cone drill bit and other comparative
Bearing on the single cone bit, teeth, cone dorsal and disposal flow was enhanced and improved, according to the cbn grinding wheels construction of various problems. Improved single cone bit in the application of slim hole drilling was a great victory, overcoming the previous single cone bit various defects, eliminating the single cone bit teeth easily fall dorsal easily pierced, too more from the drilling and drilling higher interest rates and other issues, field application is effective and can improve the sidetrack drilling speed, shorten the drilling cycle, thereby reducing drilling interest, can be applied by oblique drilling, more suitable for steady oblique drilling, more suitable for slim hole drilling.
Now commonly used in small-size drill mainly tricone bit, PDC drill bits and single cone bit, PDC drill bit due to the sds plus drill bits structure and working principle of limitation. Among them, three cone bit bearing most obvious disadvantage is small in size, mainly by the impact, crush and squeeze a small way from scraping rock breaking, drill teeth touch bottom number changes, dental discontinuity, short bearing life .
Not only work when torque is large, the cutting tools teeth washing and cooling difficulties, and its strong sensitivity of lithology, stratigraphy and is not suitable for drilling hard and soft gravel staggered formation; single cone bit more applicable than three cone drill in both strength and ductility are large formations, while for PDC bit difficult to deal with hard interlayer and other complex formation, and the structure is simple, bearing a large space, the use of safe, reliable, easy to drill size miniaturization field use to good effect.

drill coring range
At present all of our minimum core drill coring range are 12MM and above, with the largest on the magnetic drill
Drill diameter reached 160MM, if the concrete diamond blades aperture is small, then I recommend using ordinary twist drill instead. Relatively speaking Why core drill so small it can not do? First, the tile blade holes by drilling, twist drill has been able to deal with common good. In contrast, the twist is much lower than the cost of the hollow drill bit, drill steel so we did not do the smallest aperture so small. Then why do we do it rail bricks? In fact, in order to solve our twist open a large hole encountered much resistance and developed, so long as we understand this, we also know that, in fact, there is an important reason that the grinding cup wheel smaller the aperture, But we take the three core drill blade tip the higher requirements, so the production cost would be a corresponding increase, compared to the twist drill, this is definitely select twist drill more.
