DJB

5 tap. This tap: 11 yuan of ／ pay. Trial work is body of a powerful person of oriented a powerful person. 2-5-1 of thunder of QY12 of plan bugle call, material pledges for attune of 45 # steel hardness is HB 220-250. Occupy Tian Lisheng's master to tell, this tap is before trashy DJB-823 processing, every tap can machine 30 at most. Machine 5-6 hind the noise that begins Zhi having Zhi, the deepness that checks tap via using whorl plug guage is fluctuant 0.

02mm, and after going to 60 via besmearing with DJB-823 the tap of Fu is machined, still can very good use (because do not have an experiment and interrupt) , although such this tap besmear after DJB-823, life lengthens 2 times, and be in treatment process do not have noise. The product measure of treatment is stable, clean of snail the silky luster of mercerized cotton fabrics is spent raise one class above. 2. Experiment cutting tool: 6 straight handles wring Φ knife, this kinds wring a knife 3.

8 yuan of ／ are raised, trial work jams for a kind on a powerful person. QY12F 4-04 of plan bugle call, material is 45 # steel, move qualitative hardness HB220-250, bore with a reamer divides an amount 0.

13m M, hole depth 28mm. Before trashy DJB-823 is handled, tell according to Chen Jirong's master average every reamer machines 20-30 hind cannot reoccupy, and increase workpiece around size wave motion is bigger, add man-hour to still have the sound of Zhi Zhi. And the reamer of classics besmear DJB-823, the workpiece with equal treatment 80 hind still can very good use (because do not have similar work, the experiment interrupts) . Although such reamer also can improve life 2.

7-4 times, and noise is not had in machining a process. Classics actual measurement adds work measure from beginning to end invariant, bright and clean degree raise one class above. When the DJB-823 that do not have besmear, reamer speed cannot 10 meters of ／ divide prep above, speed of aperture of the bore with a reamer after besmear can amount to ／ of 6 0 rice to divide. 3. The × of other tap M12 of the experiment 1.

25, M20 × 1.

5, M14 × 1.

5, experiment through comparative treatment, all can improve life 2 ～ 10 times. 4. Vernier calipers: Treatment of 2 workshops machine measures my yard very big, its vernier calipers is average 3 months are about to send check nap. But via using two calipers after DJB-823 Tu Fu (use below coequal condition) can use 13 months to go again nap. And the two helix micrometer after classics besmear Fu, after using a year, still can continue to use. 5. Be stationed in factory of some Tai'an family member to use thick 1.

The laminose leftover pieces of 5 millimeter produces the smooth gasket on the screw of M12, they are used returning is assorted gasket die, its punch pin is made with T8, so a drift develops 2093 gasket on average to need to be repaired again grind, and after be being handled via using DJB-823, can rush continuously cut 12725 gasket, its life raises 6 times above, and place does not have burr to washerbed down the livestock. 6. Establish milling cutter: Φ 20 establish milling cutter, 21.

5 yuan of ／ are raised, adding workpiece is body of assorted boring cutter, the pivotal tool that combining boring head is treatment of oil cylinder of my factory automobile crane, and the long-standing problem that the treatment of its cutter hub is my factory. Material of this cutter hub is 40cr, quench hardness is HRc40-45, there is wide × of 4 long × on its cutter hub deeply: 30 × of 200 × the chamfer of 15, in because its hardness machines these 4 chamfer higher to need before,using up 12 of 20 establish milling cutter, if encounter cutter hub,quench sometimes HRc45 of hardness prep above, with milling cutter of steel of tool of common high speed one penetration of a cutting tool, burn out instantly edge, cannot machine at all, can use the treatment of hard alloy milling cutter with very expensive price only, and although cutter hub quenchs,with the milling cutter after DJB-823 is handled HRc45 of hardness prep above also needs to be able to machine these 4 chamfer only, and this milling cutter still can continue to use again, the life of the milling cutter after besmear DJB-823 also raised 12 times, section of every cutter hub machines cost about: (12-1) × 21.

5=236.

5(yuan) . Its milling parameter is: Deepness of penetration of a cutting tool is 15mm, cutting speed is: 60 meters of ／ are divided. 7. Two when for Jinan diesel engine the factory machines many drift set my plant die, the fluctuation pattern plate of every matrix has Φ respectively the aperture of 12 142, and ask the position between every Kong Zhi spends deviation to must not exceed 0.

02mm, its material is 45# steel, quench hardness is HB 220-240, every cover matrix more than 8000 yuan. We are like treatment previously akin matrix, need the of 12 ingot knife in choosing 10 meticulously, its aperture deviation is controlled very hard also in 0.

04mm less than, very inaccessible design asks. But a reamer of besmear DJB-823 can be machined on, the 142 × 2=284 of next pattern plate aperture, and via measuring, diameter deviation is less than the first aperture that begins treatment and the last Kong Jikong 0.

004mm, its hole wall is bright and clean degree also raised one class above. The quality of this die got an user reputably. In addition, the tap that some tool works produces Henan, the 45# steel that quenchs in treatment hardness exceeds HB 200 when, cannot use basically, but after classics besmear DJB-823, can contented treatment asks. (2) test data; See form category - a number is machined to prolong life after pattern of industry of test of hardness of plan number stuff adds workpiece to count 823 processing before 823 processing (times) can reduce cost remarks cutting tool to jam 6 straight handles wring Φ of QY12F4-04 45# HB220-250 knife 20, .

7-4 63-75% is stand-by guide × of QY12F2-6-1 45# HB220-250 M24 of body of a powerful person of a powerful person 1.

5 4, 5 55 11 91% is stand-by measure uses frequency in my factory second 3 months need identical two experimenter vernier calipers long grind 13 months to need to repair grind 4 75% - 2 50% still can be used after half an year of Alexandrine helix micrometer adjusts a year stand-by cold die.

Die of 12 gasket combination can develop the strong diameter of iron plate leftover pieces of 5 2093 can need to repair again to 12255 6 83% grind many drift to combine die Φ the milling cutter of 12 machines a die 10 times can 10 90% can raise treatment precision Φ of ZY00-02 40G HRC40-45 of cutter hub of cutting tool of a grade 20: 1, this test data is taken at my factory 2, 3 workshops; 2, cutting tool kind because 3 workshops are akin,experiment spare parts batch is less, handle the tap after to all did not wait give out to already was not had need treatment, reason the tap in afore-mentioned experiments, wring Dao Jun to be able to continue to use; 3, tap and aperture of bore with a reamer all undertake on lathe. (3) conclusion: DJB-823 is in tool of low speed cutting, measure, cold die has the application that go up. Basically be the solution that makes its 1-3 ％ above all, dip besmears or brush its besmear to arrive on the material that is about to handle. DJB-823 forms a firm ply through the chemical adsorption with parts of an apparatus to be in 0.

The overburden between 4-6um. When the tool that has besmeared with DJB-823 accordingly machines a spare parts, by the attrition between original metal and metal, turn into 823 rears grind with what add workpiece. What reduced a tool greatly thereby is main wear away- - attrition wears away, improved the service life of the tool thereby. The systematic test that passes my plant more than 3 years, proof DJB-823 not only can apply at electric equipment respect, and OK still at machining respect applying. Can prolong tool life, reduce manufacturing cost. Craft of this besmear Fu has: 1. Craft is simple and the requirement is strict; 2. Cost is low, economic efficiency is remarkable. Besmear Fu tap, screw die, reamer, plug guage, measure, average every place needs charge of electricity of material, artificial cost, water to also do not spend money of a few wool. Its investment yields than be as high as 1: 1000 above. Namely every throw 1 yuan of money to be able to call in 100-10000 yuan, 3. Facilitating promotion applies. 2, the uses unit of the test case according to my factory and brother experience of other respect, I think to besmear remarkable result can obtain after DJB-823 have the following side: 1. Cutting tool kind: Include tap, screw die, reamer, broach, push broach, the gear-shaping knife, knife that insert tine, boring cutter of vehicle of gear hobbing knife, fine, scissors, file, combine the fine vehicle lathe tool on boring machine; 2. Measure kind: The main transfer machinery inside ring gauge of plug guage of callipers, micrometer, whorl, whorl, height gauge, angle square, dial gauge, all sorts of measuring first class. In this respect, if measure is not factitious attaint, tell from some kind of meaning, all sorts of measure want removed and proper time to be handled only, so OK more the earth extends term of service. 3. Cold strong step is provided. 4. Machine tool slideway, transmission guide screw, , nut, benchwork work platform. 5. In respect of automobile crane of complete hydraulic pressure: After classics besmear DJB-823, the copper that can reduce piston lever and piston crock to go up covers the attrition force between, rise cooperate precision, those who reduce piston crock is rustily, improve the life of hydraulic pressure system. 6. Other respect: Low speed bearing, gear, copper is covered, plane shear kind reach other is easy wear away. Above discussed the function of DJB-823 and applied example, so whether can the application of DJB-823 affect an electron yuan the function of parts of an apparatus? (One) answer in DJB-823 of application of electric equipment respect take out " worries about " 4 times. 1. Contact resistor: Besmear and do not besmear osculatory resistor changes to not be more than 10 ％ . 2. Resistivity: Ω of 10 10 3. Adherent force ≤ 1 class, flexibility ≤ 1mm, cm) of · of Cm(50kg of · of impact strength 490N. 4. Solderability: The Au of besmear DJB-823, Ag, Cu, Sn, the surface of Pb can maintain the solderability of original metal. And as a result of corrosion resistance can increase, greatly reduced empty solder, false solder, sealing off. (2) answer in DJB-823 of metallic cutting cutting tool and measure respect application take out " 2 a heart " 1. After besmear DJB-823, do not affect the itself measure of mechanical component, also do not affect worker worker, the precision of model, cutting tool. 2. In DJB-823 of Fu of the besmear on measure, won't affect measure precision. Solution of all sorts of pH indicator DJB-823 measure the gotten thickness that become film below the electron microscope, for 0.

4-2 micron. Additional, those who deserve special attention is: The DJB-823 application in respect of industry standard measure, can reduce the attrition of labour, model, measure only, reduce rub bad news, raise the goal of the life of labour, model, measure in order to amount to, and unalterable their inherent hardness and intensity. Like my factory 2 workshops change the silk that M8 attacks on a tapper that make with common bench drill, workpiece is body of a powerful person, material is 45# steel, quench hardness HB 220-240, when the DJB-823 that do not have besmear, every tap can attack 5-8 only silk cannot reoccupy, when 10 tap that handle with DJB-823, attacked 15 silk except beyond, other attacked 5-9 9 times only silk, the life of the tap after Tu Fuqian is almost invariant. After the experiment fails, via anatomize, I discover this tapper uses up tap so big, because be when tap,be, pair of neutral of the aperture below tap are very poor, because wear away,major tap is not send bad, pass because of twisting fire however big, and break off or drop tooth, besmear apparent effect is not had after DJB-823 so. Apply DJB-823 in promotion accordingly must suit the remedy to the case, specific issue is specific analysis, must not build in order to slant complete. CNC Milling
