diamond tools in China business development on Reflections

An industry, the industry's overall level of development ultimately depend on the level and growth of business. Of the diamond tool industry in order to achieve success from large to strong changes, the need for enterprise independent self-reliance, self-improvement, which will promote the  GUSHI concrete polishing pads development of the industry.
1. Clear corporate strategic positioning, enterprise synergies and improve the overall competitiveness of
Over the years, the domestic diamond tool business has experienced raw material prices, the export tax rebate rate, the RMB against the US dollar continues to appreciate, the world economy is slowing down, the domestic floods, earthquakes and other natural disasters and other adverse factors, to bring greater business all enterprises pressure.
How to enhance the competitiveness of enterprises to deal with complex business situation. First, enterprises should clear strategic positioning, according to their own reality, to develop viable development strategy, give full play to their strengths, to make their own fist specialty products. Avoid homogeneity, low-end, low-cost vicious competition. Secondly, we must play to the enterprise cluster synergies and improve the entire industry a competitive advantage, we must attach great importance to and give full play to the role of associations, give full play to association information platform, industry management and guidance, and guide enterprises in the industry gradually embarked orderly competition and healthy development track.
Around the tool industry, broaden and extend its product line, improve the product line; always adhere to the technical and management innovation; focus on the brand, sales channels and cultivate corporate  GUSHI concrete diamond blades culture construction, adhere to the balanced development of domestic and international marketing strategy , committed to continuing to build a business, fast growth and healthy development of international famous enterprises.
2. Strengthening scientific research and technology investment, improve the capability of independent innovation
Strengthen the independent innovation capacity to promote fundamental to long-term development, particularly in the context of economic globalization, growing international competition, lack of independent innovation ability will affect our survival and development of the diamond tool industry. At present China has built several national technical center, but so far, the diamond tool products companies in only a few provincial corporate research centers, and has more than 1,000 manufacturing enterprises, the annual income of nearly billion industry level is not commensurate. Therefore, China should realize the diamond tool industry from large to strong changes, you  GUSHI tct circular saw blades must also carry out all the work of independent innovation.
In recent years, some enterprises in independent innovation capacity-building to do some work in the technological development has also made some breakthroughs, but, objectively, in terms of research investment also studied the depth, product level, personnel structure, all there is a large shortage. Currently, companies are further increase investment in scientific research and technology, has "Enterprise Technology Center Project" included in the listing and financing projects to improve technology center hardware facilities, the construction set diamond tools, metal tools, power tools into one comprehensive state-level enterprise technical center.

How to replace the worn drill

After some time working in the underground drill , drill scraper blade diameter becomes smaller, shorter, blunt , rock crushing capacity will become weak , slowing progress . Tags: geological coring drill concave three wings drill
Drill a certain time after the underground work , scraper blade diameter drill bit smaller , shorter, blunt , rock Crankshaft Grinding  crushing capacity will become weak , slow down progress ; cone bit due to the erosion of tooth wear , bearing damage , can cause cone rotation is not flexible or cone stuck, the torque increases, if not promptly fall from the cone accidents will happen ; diamond drill due to heterogeneity caused by the formation of PDC drill bits crack occurred on , off, off Similarly the drilling footage slower. To speed up the pace of drilling wells whole , must be replaced with the old drill , and drill a few hundred meters to several kilometers in the underground , how to replace the drill bit drilling workers do ?
When drilling rig power driven  hone tool  turntable, kelly , drill and drill bit rotates through the instrument to observe the work of the underground drill rig floor , after the comprehensive judgment, if deemed drill has been worn , replace the drill bit must immediately stop drilling . After stopping drilling, drilling fluid circulation to maintain a period of time , the purpose is to adjust the good performance of the drilling fluid , and the suspension in drilling cuttings out of the ground, the cycle of the new borehole wall remained stable , while also to carry out routine checks on drilling equipment . Workers drilling derrick crane use on the traveling block and hook, according to the height of the mast by column ( generally consisting of two or three drill ) from the entire drill string from the well . After the drill column in the order from the discharge in the derrick while the drill string downhole stone polishing pads  proposed , to use a pump to keep the annular space drilling infusion fluids , the aim of maintaining the liquid level does not fall within the wellbore so that a wellbore pressure to balance the formation pressure to prevent borehole collapse or underground formation fluids into the wellbore . Meanwhile, we should pay particular attention to the reduced diameter borehole drilling may occur card , the operator should be strictly controlled to improve speed. The entire drill wellbore , drill collars from the rear , while the need to replace the drill bit will play out , workers remove the old drill press drill fitted with a new column under the original order can be restored to the wells after drilling

types of grinding inner circle

Grinding inner circle divided into the following four categories: speed electric aerostatic bearing inner circle grinding, grinding inner circle of mechanical transmission, pneumatic and electric grinding inner cutoff wheel  circle inner circle grinding.
Aerostatic bearing speed electric grinding inner circle: The aerostatic bearing (supply pressure is 40 ~ 65MPa), grinding system rigidity, both electric grinding characteristics, speed up 180000R/MIN, suitable for grinding a ~ 10MM hole.
Inner circle grinding mechanical transmission: mainly by the spindle, bearings, sleeve body shell, flat supporting pulleys and other components. Then, after replacement of the long axis, is used wet diamond polishing pads  to grind different bore diameter and length, for comparison, the use of low speed, the speed is generally lower than 2000R/MIN.Wind-driven inner circle grinding: spindle with a turbine driven by compressed air turbine rotates the spindle speed, spindle speed reaches 10000R/MIN. Moreover, small vibration, pressure can be adjusted stepless. And with regulators, filters and other accessories.Electric grinding inner circle: A three-phase floor polisher pads  asynchronous motor direct drive, and another by a high-frequency electric motor driven spindle speed of up to 50000 ~ 90000R/MIN. Output power is larger, instantaneous overload, speed characteristics hard, little vibration.

A carbide circular saw blades and alloy head has a sharp edge-sensitive

so the movement of the blade, installation and removal process, you must be careful to protect alloy head from injury.
2 Regularly check the machine spindle runout (± 0.02mm), and swing (± 0.01mm).
3 blade must be removed before installation flange on the spindle and debris. Flange surface should be smooth, clean and axes are mutually perpendicular.
4 Use the largest possible blade flange makes  turbo blades more stable operation, flange size should be consistent with the size of the blade flange diameter of 1/3 (thin blade flange should adopt 1/2D ) Sawing better (especially thin blade).
5 blade should be installed after a smooth idle 30 seconds, if everything is OK before you start cutting work.
6 blade flange nut during installation must be elastic medium, too loose in the rotating cutting blade will slip, too tight or deformed saw blades have internal injuries affecting cutting performance.
7 before cutting blade operator must take a good protective equipment (safety glasses, dust masks, helmets, protective gloves) and check the saw guard is intact.
8 of the following circumstances, the need for timely grinding.
a) no longer meets the requirements sawing quality.
b) When the machine energy consumption significantly increases.
c) the cutting edge of a clear material, when population explosion.
d) achieve the 0.2mm alloy edge wear.
Grinding time is very important, because it  wet saw blades is not a sharp blade at work, saw the body may have a fever, also causing the motor load is too large, reduce the life of the blade. Shall be grinding at the time to continue cutting, cutting every 10% increase in volume, will bring an additional 50% of the alloy damage and shorten the life of saw blade.
9 must be cleared regularly serrated and saw gathered at the side of the resin plate, debris and other debris, because the adhesive material constantly accumulated, the resistance will increase, resulting in high energy consumption (in extreme cases, can cause the machine motor burned) and rough cutting quality. If both cutting edge is blunt, it may cause damage to teeth.
10 Avoid using aggressive cleaning solvents, long blade when not in use, should be cleaned sharpening, buy oil for rust treatment, and  table saw blades in its original carton and then properly placed inside.
11 using sophisticated, stable, vibration-sharpening machines, and suitable diamond wheel. Accordance with the prescribed procedures to repair the running head of gold, will extend the life of the blade, do not use hand-operated grinding equipment.
Sharpening the attention in strict accordance with specifications Plains BLOG sample geometry designed to grinding.

diamond saw blade speed by equipment conditions

(1) diamond blade speed: in practical work, diamond saw blade speed by equipment conditions, saw the quality and the nature of the restrictions before sawing stone. From the optimum blade life and cutting efficiency, it should be selected depending on the nature of the stone saw blade speed. Sawing carbide drill bits  granite, the blade speed at 25m ~ 35m / s within the selected range. For high quartz content and difficult cutting granite, remove the blade speed limit is appropriate. In the production of granite tiles, the use of smaller diameter diamond saw blade, wire speed can reach 35m / s.
(2) Cutting Depth: diamond cutting depth is related to wear, effective cutting, saw cutting force conditions and the 12 inch saw blade  nature of the important parameters of stone. Generally speaking, when the line speed diamond saw blade is high, should be selected for cutting of small depth, from the current technology, the cutting depth of the diamond can choose between 1mm ~ 10mm. Usually with a large diameter saw blade cutting granite blocks, the cutting depth can be controlled within 1mm ~ 2mm between the feed rate should be reduced at the same time. When the line speed diamond saw blade is large, a large cutting depth should be selected. But in performance and tool strength saw the extent permitted, should try to take a greater depth of cut for cutting to improve cutting efficiency. When the machined surface colde saw blade  when requested, should be used small depth of cut. (3) diamond saw blade feed rate: Feed speed incurs sawing stone feed rate. Its size sawing rate impact, the force and the cutting blade heat dissipation area. Its value should be based on the nature of the selected cutting stone. Generally speaking, sawing softer stone, such as marble, may be appropriate to increase the feed speed, if the feed rate is too low, more conducive to high cutting rates. Sawing fine structure, relatively homogeneous granite, may be appropriate to increase the feed speed, feed rate is too low if the diamond blade easily be polished. But sawing UNEVEN coarse granite structure, should reduce feed speed, otherwise it will cause the blade vibration and reduce fragmentation leading diamond cutting rates. Granite cutting feed rate is generally 9m ~ 12m/min within the selected range.

marble flooring stone maintenance methods

 Solution one: Using the compound before test a small inconspicuous area, such as a corner, and that does not make the  green concrete blades dark stone surface covered with scratches. Clear minor scratches operation is relatively simple, there is a lot of polishing powder sold. However, when using the polishing powder, most still require polishing machine or with the use of single-brush machine.
Solution two:
Recommend the use of liquid medicines, preferably two copies of the enzyme cleaning agents which can penetrate the dry core bits  underlying stone, and can filter the dirt and grime to the surface. Enzyme vegetable stains particularly effective. Such cleaning agent available from high quality reseller of stone cleaning products purchased.
If the effect of this method is still not clear, the proposed solution of the enzyme detergent and decontamination powder mixed until a viscous creams similar to peanut butter. The mixed creams apply to pollution site, cover with plastic film, sealed with adhesive tape around. Maintaining 24-72 hours reaction time, followed by drying with a bamboo board to scrape ointment. If necessary, repeat it again. Once the contamination is removed, it is recommended to protect the stone repellant permeability, again in the future to avoid contamination.
If there are stains on the marble surface scratches while, it needs to be polished. Abrasive powder choices need to determine the construction side, there may be brick soil, cinders, sand paper or emery. Process may be more complex, so it would be best treated by professionals to operate. To clear some 305X305X10mm specifications sheet, it may damage their heels deep into the stone house, it may be difficult or almost can not afford sanding scratches. This situation is best seek expert assistance.
Solution three:
About bathtub ledge around the edge of the marble polishing pads  stone and stains, the problem should be out in these marble never been protection, or improper maintenance. Since the performance of mild detergent ineffective, we recommend using a neutral cleaning agent and as thick powder to reconcile into a mixture of mud, the medicine paste deposited into the stone surface, then rub with a nylon pad. Powder in which the role of similar an abrasive that helps remove surface stubborn stains. If using this method does not work, it is recommended to use alkaline cleaning agent and clay powder are mixed to form a strong cleaning agent solution, other operation processes described above.
Speaking scratches on the ground, it is recommended to professionals to the scene to inspect and re-polishing marble surfaces. Since re-polishing usually requires the use of liquid or powdered products, or diamond polishing pad, so consult a professional to operate best. Available from local stone manufacturer or dealer inquiries, please recommend it more well-known stone care products, and for professional handling.
Often occur in the course of tiles loose, fall off and so on, because the current tile adhesives used in cement mortar bond fastness is not enough, and the long-term in a damp environment, so easy to loose and fall off. There is a method using a resin type adhesive paste tiles, not only to meet or exceed the strength of the tile body strength, and long in a humid environment will not cause loss.
Bathroom tiles are often greasy, water, rust, soap scum and other defile, to keep the porcelain surface cleaning without damaging the enamel surface shiny, you can use multi-Scouring pastes and clean. As for the tile gaps, first with a brush dipped in a little cream decontamination remove dirt, and then in the crevice brush a waterproofing agent can, so that not only impervious to water and can prevent mold growth. It is worth mentioning that a large number of families currently used for cleaning disinfectants contain a great influence on the pH of natural stone and other chemical substances, the color of the stone surface and internal mineral composition adverse reactions. Particularly serious, most of the cleaning agent must be in the stone surface reactions have the effect of at least five minutes, but during that time cleaning agent has been destroyed stone, so the stone surface should be cleaned bathrooms neutral pH value cleaning agent.
Alkaline cleaners can remove grease stains all kinds of animal and mechanical oil, and remove the ground layer of wax. Enhanced oil such as special cleaning agents; powerful wax from the water. PH detergent if used improperly, can cause cleaners in addition to waste, are also varying degrees of damage to the cleaning surface, and may even cause damage to the user's skin or eyes. Therefore we use acid detergents should note the following:
To understand their uses and contraindications should read the instructions carefully before use, or consult the supplier to obtain detailed user guide.
Before you use it in an inconspicuous place to do sample test to confirm cleaning materials will not cause harm to the premise of the dilution ratio used in accordance with the true work of cleaning solvents to dilute wearing work gloves, if necessary, wear goggles.
Avoid contact with skin or eyes stay cleaner cleaners cleaning the surface in time can not be too long after use with water over the net.
Can not be used on acid-sensitive surfaces, such as some detergents for marble, glass, metal and other surface damage effects
