Investment casting is a kind of casting process. Some people call it "lost wax casting" or "precision casting". It can also be said to be a special casting improved from ordinary casting. Its precision and surface finish are higher than Ordinary casting is much higher. In some places where the precision requirements are not very high, investment castings can be used and assembled directly. Even in some positions that require precise assembly, we can meet the required requirements through local secondary CNC machining of the product, which can reduce the product's cost. Below are some of the investment castings we have done.
SCZY committed to the production of stainless steel, carbon steel, alloy steel and copper and other Metal Casting parts, and also provides professional follow-up secondary CNC machining (for places with high precision requirements and direct casting cannot meet the requirements) and various surface treatments etc. Our investment casting parts accuracy achieve CT4-6, surface finish Ra.1.6~3.2μm and the wall thickness can be reach 0.5mm. Our high-quality engineering team and quality inspection team ensure product excellent quality and in time delivery. We would be happy to provide a free quote

(2) After a period of use, fasten the front and rear wheel nuts; check and adjust the tension of all the V-belts; check and adjust all the drive chains; clean the dry air filter when the indicator light is on; And radiators; check the coolant level and fill it up; check and clean the water collector; check the fuel filter, let go of deposited water and deposits, clean the hydraulic tank filler and check the oil level. The combine harvester is parked on level ground, inspect the oil sump of the engine oil and refuel as needed; tension the unloading grain to stir the dragon steel rope; clean the hydraulic drive tank filling port and check the oil level. Clean the cab filter if necessary.
(3) After 1 quarter of use, replace the fuel filter and replace the engine oil filter. Check the electrolyte proportion of the battery and charge or fill with distilled water as required. Check the coolant level and fill it up. Clean the fuel oil pump, check and adjust the clutch clearance, check and adjust the foot brake, adjust the hand brake soft shaft.
2, hanging combine harvester (1) tractor maintenance. Always maintain the tractor and maintain the best technical condition. Always follow the instructions in the instructions for maintenance. Because harvesting is done under harsh conditions, dust, grass and more, the radiator can easily be blocked, causing the water tank to open the pot, and the air filter is also easy to fail, the filter is blocked, the engine power is reduced, Black smoke is emitted when working under heavy load, which makes it difficult to start the starter. Therefore, the grass clippings and dust on the radiator should be cleaned before leaving the vehicle. This work must be carried out regularly during each working interval. Add a dense net cover on the front of the car to better protect the radiator. Increase the number of times the air filter is cleaned or raise the position.
(2) Harvester maintenance. Combine harvesters should regularly lubricate daily work; check the technical status and fixed conditions of each working part; make necessary adjustments and eliminate faults that have occurred. 
1. Self-propelled combine harvester (l) Daily lubricating oil according to regulations for each lubrication point.
