China's manufacturing underdeveloped. I studied mechanical manufacturing, talk about some of my experiences. When I factory chefs in order to make a precision CNC machine tools to improve regardless of White Nights and debug information in German translation, when I Exhausted and no holidays and overtime, covered with dirt, Man Hand hurt small excavators price list, the operation failed numerous times but eventually create the first machining accuracy requirements expected of 0.0001 mm sample, I am excited for a while, but then there has been a sense of loss, because that Taiwan CNC machining centers are German-made, computer numerical control part is made in Germany, processing software or is German-made, even a turning, a bit small hydraulic excavators are made in Japan! In addition to the plant, not the same as the tool is made in China! Even the plant also draws on the experience of foreign countries, fellow citizens, you're not out of this may not have a profound experience, I want to process an accuracy of 0.0001 mm parts, tools needed, that the above-mentioned foreign-made things, these tools high precision accuracy than the product several times or even several times a few times! A little bit of small and medium excavators prices for high-precision machining, we just can not ah! Japan's better to buy a few thousand ah! I can not do anything ah. How excavator proper maintenance? Excavators, youth and mini excavators, but also the machine to play the biggest role in the stage. This time though the parts have been out of the run-in period, are lubricated with the place, but not without restraint has been increased workload, the best you can have a maintenance schedule. Day care: check oil, water, gas leaks and mechanical overheating; Check the engine oil, coolant and hydraulic fluid level; check the tire pressure and damage; check the meter and lighting; the hinge point pressure injection butter . Week maintenance: Replace the transmission oil, wash the filter pan; engine oil change; check the battery fluid level, the battery terminals coated with Vaseline; check the rim and the brake disc bolts, axle bolt fastening; check the fastening bolts fastening. Check the front and rear axle oil level; clean air filter (replace the filter if necessary); wash oil, diesel oil, transmission oil filter; check the working device, the frame around whether the weld cracking. Monthly maintenance: replace the front and rear axle gear oil; clean diesel fuel tank suction strainer; remove the water tank, the radiator surface contamination; replace the engine oil, replace oil, diesel oil filter; replace the gearbox oil and oil filter; Check the engine valve clearance. Check the operation of the engine; check the hydraulic system work; check the steering system performance; check the brake system performance, replace the brake fluid.泰安嘉 and Heavy Machinery Co., Ltd.
