Hollow drill bit is made of what material

Hollow drill bit is made of what material? Imports of steel drill bit, drill the rail where to buy? Hollow drill bit is what material do? Hollow drill we have used, you know what material the hollow drill bit to do it? Its name suggests is no hollow drill drill drill core, typically used for processing some of the large-diameter hole through the workpiece or precious metals, with high efficiency, accuracy good results. Hollow drill called core drill, magnetic drill, magnetic drill bits, hole saw drill bit used hollow shank type: straight handle, universal handle, Nitto abrasive grinding wheels  handle, handle drill overtone Category: HSS drill bits, carbide drill tungsten steel drill bit; cutting of depth: 35MM, 50MM or 100mm Specifications: 12MM to 100MM; drill main materials are high-speed steel; powder metallurgy; Carbide category. Suitable Motor: magnetic drill / magnetic drill / drill / lathe / milling machine, type, complete specifications, applicable to imports of various brands of diamond magnet (magnetic drill) and general drilling, milling, boring, etc.
The products and supporting the use of tct circular saw blades  imported magnetic drill, drilling efficiency is 8 to 10 times the normal drill. Hollow drill steel can be precision, high speed perforation can also play overlapping holes 三枚 combination blade edge portion of the structure of some of the hollow drill bit used, each blade in the cutting process, the burden of the workload only about 1/3 of , plus the inside of each blade are also cutting knife. So you can make the chip very smooth, but also extremely difficult to produce chipping. Recommended reading: What is the role of drill core and features
Hollow drill and twist drill compare people to use as a cutting tool twist drill has been a hundred years of history. Since the twist drill head core portion is completely negative cutting angle, the cutting resistance is large, so the twist drill cutting force is 50% to 60% of carbide drill bits  the core caused because of the drill bit. Coupled with the factors of steel, so can not do much twist drill. Some of the larger deeper hole machining must start from the drill hole to expand step by step until the reamer size to meet the requirements so far.
The advent of the expanded hollow drill bit cutting range, using relatively small power can be processed macroporous deep.

Carbide saw blade manufacturers tell your maintenance methods and requirements

Saw-cut steel composite panels, rock wool sandwich panel saw, cutting copper blade, cutting blade iron, aluminum cutting saw, woodworking saw blades, PCD saw blades, precision panel saw blade, multi-saw Saw, Saw exclusive diamond quartz material, non-porous ceramic stone dedicated diamond saw blades, diamond saw marble, granite diamond saw.
Blade maintenance methods: 1 blade if ceramic tile saw  not used immediately, it should be flat or use the hole to hang it up, can not be stacked on other items or foot flat blade, and pay attention to moisture, corrosion .
(2) When the blade is no longer sharp cutting surface roughness, it must promptly re-grinding. Grinding can not change the original angle, and destruction balancing.
3 inner diameter of the blade correction, the positioning hole machining, etc., must be performed by the manufacturer. If the process is bad, will affect the product effect, and potentially dangerous, reaming should not be over the original aperture 20mm, so as not to affect the balance of the blade stress requirements: (1) when the work piece should  sanding disc for drill be fixed to ensure the profile positioning comply with the direction of the knife to eat to avoid abnormal cut, or not to apply lateral pressure curve cutting, smooth feed to avoid the impact of the blade contacts the workpiece, resulting in blade breakage, or workpiece flying out of an accident. 2, work and found abnormal sound and vibration, cutting surface roughness, or odor, you must immediately terminate operations, timely inspection, troubleshooting to avoid accidents. 3, at the start and stop cutting cutting, do not feed too fast to avoid broken teeth and damaged. 4, if the cutting aluminum or other dry cut blades  metal, to use a dedicated coolant to prevent the blade from overheating, resulting in tooth paste, and other damage, affecting the cutting quality.
5, flutes and suction equipment to ensure smooth flow of slag device to prevent slag accumulation into blocks, affecting production and safety.
6, when dry cutting, do not cut long hours, so as not to affect the life of the blade and the cutting effect; wet sheet cutting, water jet cutting should be added, to guard against leakage.

How to choose a good quality core drill

How to choose a good quality core drill ? Used magnetic drill drilling engineers may have distinct magnetic drill drilling speed really is not an ordinary hand drill comparison . Good times but the price is hollow drill twist drill head . So buy the right track to good hollow drill manufacturers consumption is very important. So what kind of Concrete saw blades  hollow drill core drill is considered good ? How to choose a good quality core drill ?
I have talked to many customers about this topic. The answer generally have few , there is a trust -based client that is collaborative and after some suppliers will have great confidence in the products are supplied to provide a good product . We will also improve our quality selection system for customers good quality first hurdle ; Some customers are advocating brand type , or some kind of a common brand name products compared to agree , so the time of purchase , know or direct purchase of a certain category diamond blade saws  of branded products, other brands of products to try ordinary little or rarely use . Such customers rarely have the opportunity general more suitable to my contacts , products are often cut in , it may be said that many customers will be repeated after it was selected choice of a particular brand of product , and continue to have a good use after the course Some big brand products are indeed the passing rate on the quality control and quality management is 4 inch saw blades  very strict, so there is little "winning " situation attack. Another type of customer choice hollow drill bits, to simply learn to pragmatic type , I thought it only appropriate choice , either the price or quality , some brands may know very well , but the quality is not his only reason for choice .

Factors affecting the surface of the polishing sheet cutting

Factors affecting the surface finish using abrasive methods can mold surface smooth, smooth degree with the following factors :
1 , ( there are differences tend to increase the difficulty of the polished steel surface hardness variation or characteristics ) of steel quality.
2 , heat treatment ( heat treatment in many ways affect polishing performance ) .
3 , polishing ( polishing process and polishing supplies a direct impact on the polishing effect ) .
Polishing technique is generally sds hammer drill bits  considered the most important factor , proper polishing , cutting slices using a good polishing supplies , with good quality tool steel and proper heat treatment process to achieve satisfactory finish. Conversely, polishing techniques and supplies used improperly, even with the best quality steel will not reach the height of the mirror effect.
Whetstone is Hashimoto After years of successful experience in product research and development , including GC and CARBON Whetstone Whetstone . This feature is used Whetstone balanced with sand binder regulation strictly control the sintering temperature is substantially zero inclusions practice . This Whetstone is water-soluble with water-soluble so that the liquid Whetstone , Whetstone using surface active agent solution which can reduce the incidence and Whetstone job scratches scratches , and to improve the quality of the calm surface of the mold . GC whetstone for heat treatment ( hardness of 50 degrees or more ) steel ; suitable pre-hardened steel ( hardness 40 degrees ) in the steel.
HASHIMOTO diamond paste
This diamond paste is characterized by  diamond blade circular saw the concentration of diamond particles 3 times higher than other brands , and therefore better reflect the advantages of diamond particles in the dispersion and stability . With the diluent used to make steel mold to achieve the perfect effect finishing . Diamond paste body is constructed from polycrystalline diamond particles together , due to equalization containing fine crystals more acute crystal surface scratches can be reduced and the generation of the clearance hole of the mold surface during the grinding process to achieve efficient operations . The single crystal structure of diamond paste is made ​​from a single crystal , cutting the sheet due to the grinding process acute scarcity crystal plane of the mold surface is likely to cause scratches , while the sand is also prone to the phenomenon of hole .
TIG welding mold technology

Select abrasive wet cutting method and cutting pieces

Wet abrasive grinding wheel cutting method commonly used for cutting, according to the material to be cut , it may need to use a grinding wheel with different ingredients. Grinding wheel will be affected by the choice of material hardness and toughness .
Wet Wet abrasive cutting method abrasive grinding wheel cutting method commonly used for cutting, grinding wheel abrasive and adhesive. When cutting , the grinding wheel with coolant flushing to prevent damage to the specimen due to frictional heat . The cooling fluid also remove chips cut area. Select the grinding wheel wheels
According to the material  concrete saws to be cut , you may need to use a grinding wheel with different ingredients. Grinding wheel will be affected by the choice of material hardness and toughness . Split carbide ceramic or diamond bonded materials should be chosen from the phenolic binder made ​​of metal or cutting disc . Using phenolic adhesive bonding of aluminum oxide (Al2O3) grinding wheel is a typical choice of black metal material cutting . Cubic boron nitride (CBN) are increasingly used in higher hardness cutting ferrous materials . Non-ferrous metal cutting should be selected by the phenolic adhesive bonding of silicon carbide (SIC) grinding wheel . Cutting wheel design
Grinding wheel designs should be considered in addition to grains , we must also consider the difference between diamond / CBN cutting disc cutting discs and SiC/Al2O3 between . Due to high hardness and abrasive with a durable adhesive fixed abrasive , diamond cutting wheel CBN / performance is very durable . Metal disc perimeter ( continuous rim ) just stick a thin layer of abrasive. These are long-term consumable cutting wheel cutting disc . SiC and Al2O3, and other abrasive wear relatively fast , relatively inexpensive . Thus, the entire body from abrasive grinding wheel and a binder . This cutting wheel cutting disc is called self- consumption . Characteristics cut pieces
Long-term consumption of cut pieces ceramic tile saw from the cutting long pieces generally consumable diamond cutting discs , diamond cutting discs there are two to choose from , they use different abrasive binders - A cutting pieces of metal adhesives, other kinds of phenolic adhesive is applied . Both can be used for cutting sheet cutting extremely hard materials. Higher metal adhesive applied to the brittle materials such as ceramics. Phenolic binder is capable CBN cutting materials like carbide cutting wheel just Bakelite adhesive types available , suitable for cutting extremely hard white cast iron and other ferrous materials . Consumable consumable cutting disc grinding wheel cutting disc generally , this cutting sheet cutting characteristics  concrete saws with different adhesive properties vary . According adhesive " hardness" or abrasive capacity retention or discarding divided into different categories . Abrasive ability to maintain " rigid " grinding wheel is better than " soft " grinding wheel . " Soft " grinding wheel for cutting hard , brittle materials , because this grinding wheel will break down with the lower hardness binders , continue to add new , sharp abrasive . When cutting soft and ductile materials , adhesives should choose a higher hardness grinding wheel . Further , the higher the hardness of the adhesive wear of the cutting wheel is slower , and therefore more economical. Select the correct cut for the particular sheet material is very important. Only the correct cutting disc to ensure that small amount of deformation , smooth surface . After cutting the higher surface quality , the speed required for the preparation of the results obtained faster .
