Performance and technical data of main parts of 2.2 non - grinding machine

2.2.1 spindle and bearing

The spindle bearing, carefully scraping, dynamic and static pressure are integrated, technology, design, the whole world only invention patents, leads the world.

The spindle by Japanese advanced SNCM-21H alloy steel, after quenching and tempering, carburizing heat treatment by computer control after cryogenic treatment, the surface hardness of HRC-62 degrees, unilateral effective hardening layer is more than 1.5mm, after repeated precision grinding, high precision, strong rigidity, no deformation, the company with advanced transmission mode, support processing a fixed sand servo motor is fixed on the main body, with servo motor direct drive, so as to solve the spindle by the belt tension and deformation, using the world's advanced hybrid circuit, to steel and toughness of various steel can be adjusted, can totally achieve the demand of various materials, without any rotation of the spindle resistance, service life of up to 10 years. After the grinding wheel spindle assembly is completed, all the dynamic balancing test is less than 0.001mm. The wheel spindle direct drive servo drive way, with the German Rost reducer, with the same dynamic hydrostatic transmission advanced in the world, without any outside force, after the completion of the spindle assembly, by dynamic balance test correction beating within 0.001mm. And by the numerical control drive variable speed, in order to do the Dingzhou speed grinding, speed can be adjustable speed operation.

2.2.2 bed

The bed body adopts advanced meters Hanna cast iron, nodular cast iron and copper (in German formula, at the same time (Si, Mn, adding nodulizer, copper, molybdenum casting). After normal heat treatment two times tempering and aging treatment, in order to stabilize the internal structure, the thickness of 40mm mechanical design ontology is reasonable, body stiffened to body feet, excellent material to ensure that in the process of using never deformation and abrasion resistance. Reasonable mechanical principle design, pay attention to each detail design, body weight of about 7.5 tons

2.2.3 main shaft circulating oil system

Spindle automatic lubricating oil circulation (Germany VAILLANT advanced spindle oil 10#) and pressure dressing device for the same pump system, external tank temperature, convenient cleaning and changing, spindle oil circulation filtering two oil filter device and a pressure controller, pressure gauge wheel spindle 10, a small shaft tile pressure gauge 3, let each pressure control with digital data, 6 wheel spindle pressure gauge, pressure gauge 3 small wheel bearing, spindle oil has a constant temperature air conditioning device, spindle runout is less than 0.001mm in the world are very high accuracy requirements, no one country can out of this standard, to ensure the accuracy and service life of the spindle.

2.2.4 adjusting wheel drive system

The adjusting wheel spindle drive motor with DELTA servo motor and reducer in Germany, direct drive spindle, spindle rotates without any tension and resistance, and the traditional transmission mode is completely different, the speed control of 0~260rpm (digital control) can be arbitrarily set speed, spindle runout is less than 0.001mm, no one country can be adjusted to the standard. The optimal speed of adjustment, when the wheel diameter changes can still maintain the same speed, grinding out the best products.

2.2.5 diamond wheel dressing and shock proof technology

The German high long high precision grinder design a diamond wheel dressing device installed in the wheel box cover, such dressing can be either in the dressing of diamond wheel dressing, grinding wheel size to meet the different requirements of technology. When the dressing seat is separated from the grinding wheel cover, the best static effect is achieved when dressing the grinding wheel, and the grinding wheel is smooth. At the same time, the guide rail is moved with static pressure, and the traditional non lubricating system is completely different. When used and the guide rail without any resistance. Long-term use stability

2.2.6 wheel dressing technology and horizontal adjustment

The design of a horizontal adjustment port of the high precision Centerless Grinder in the wheel shaft seat position on the High German long, the guide wheel lateral displacement before and after 20mm, when the end face of the grinding wheel wear width becomes small, horizontal adjustment guide to solve the grinding wheel and the regulating effect of grinding when the accuracy of the deviation of the. At the same time in the dressing of wheel rail with hydrostatic oil dynamic principle, use and back track without any resistance. Long-term use stability.

22.7 linear motor feed grinding technology

High German long company uses the Japanese advanced Sadegh linear servo motor and servo feed system, gapless feed, feed for a minimum of 0.0001mm, using advanced hydrostatic oil floating guide rail model, using the principle of hydraulic expansion coefficient, after scoring will be more stable, the feed will be more accurate, and the use of advanced German Heidelberg grationg ruler LS1378C every time, ensure accurate feed, feed input instruction, grating ruler automatic detection, if not into, it has issued a directive to go forward, until into so far, now we can go to the 0.0001mm in the world, is full of balls in a problem solved, only we can do a retreat knife like precision.

22.8 grinding machine with constant temperature technology

Spindle oil constant temperature technology, any one of the principal axis of rotation will be hot, we are in the spindle oil with constant temperature air conditioning, so that the rigidity of the spindle and temperature.

Accuracy acceptance criteria

1), cutter set 0.0001mm

2), outer diameter tolerances of 2.4985mm ~ 2.4995mm

3, true garden degree 0.0003mm cylinder 0.0003mm

4), Japanese Sanling Japanese Sadegh, increase the waterproof super linear servo motor, servo motor Delta

5), grinding wheel dressing, diamond wheel

6) to be able to do the product of ceramic zirconia insert core diameter 1.25mm outside diameter size tolerance 0.0005mm - 1.2490 and 2.5 of the workpiece diameter tolerance 0.0005mm - 2.4990

7 output per hour 800
