How to use CNC crankshaft grinder to process the crankshaft of diesel engine for internal combustion locomotive?

The crankshaft of a diesel engine for a diesel locomotive is a vital component. The main function of the crankshaft is to convert the reciprocating linear motion of the piston into rotational motion, thereby driving the wheels of the diesel locomotive. It bears the gas pressure, reciprocating inertia force and rotational centrifugal force from the piston, and transmits these forces through the connection with the connecting rod to keep the engine running.

Recently, Shanghai ANTS Machine Equipment Co., Ltd. received a Greek customer. The customer requested to use a CNC crankshaft grinder to make the crankshaft of an internal combustion diesel engine. The crankshaft length is 4000mm and the diameter is 500mm. The engineers of Shanghai Antis matched a suitable CNC crankshaft grinder for the customer: M82126.

The M82126 crankshaft grinder is suitable for grinding high-speed, medium-speed and low-to-high-speed marine diesel engines, locomotive internal combustion engine crankshafts, and other large-scale power machinery crankshafts. It is suitable for single-piece production, small batch production factories and repair factories and other departments to grind the crankshaft main journal and crank neck. Within the cutting range allowed by the machine tool, the machine tool can be equipped with a correction chuck to clamp the workpiece according to various needs, and the user can grind the crankshaft crank journal of the crankshaft. When grinding the main journal, the crankshaft can be supported by the center and the mechanical center frame, and the workpiece can be rotated by the pull rod to grind.

Next, an engineer from Shanghai ANTISHICNC will give you a brief introduction to the processing flow of crankshaft grinding by crankshaft grinder:

1.Preparation: Select a suitable crankshaft grinder and ensure that it is firmly installed. Prepare the required fixtures and measuring tools, as well as the grinding wheel and coolant required for grinding.

2.Install the crankshaft:Use a fixture to fix the crankshaft on the grinder, ensuring that the center of the crankshaft is aligned with the center of the spindle of the grinder. Adjust the clamping force of the fixture to ensure that the crankshaft does not move during the grinding process.

3.Adjust the grinder:According to the size and shape of the crankshaft, adjust the parameters such as the table stroke, grinding wheel feed speed and grinding depth of the grinder. Ensure that the adjusted parameters meet the processing requirements.

4.Grinding the crankshaft: Start the grinder, rotate the grinding wheel, and slowly move the workbench so that the grinding wheel gradually contacts the crankshaft surface. During the grinding process, pay attention to controlling the grinding depth and feed speed to avoid over-grinding or burning the crankshaft surface. At the same time, continuously inject coolant to reduce the grinding temperature and prevent the crankshaft surface from burning.

5.Measurement and inspection: During the grinding process, the size and shape of the crankshaft should be measured regularly using measuring tools to ensure that the processing accuracy meets the requirements. If the size or shape is found to be unsatisfactory, the parameters of the grinder should be adjusted in time for correction.

6.Cleaning and maintenance: After the processing is completed, the chips and coolant on the grinder should be cleaned in time, and the grinder should be maintained and maintained to ensure its performance and accuracy.

It should be noted that when performing crankshaft grinding, the operation procedures should be strictly followed to ensure safety. At the same time, appropriate grinding parameters and grinding wheels should be selected to improve processing efficiency and quality.
