Cutting tools play a key role in the machining of engine components, used to form and finely machine various components, including crankshafts, pistons, cylinder blocks, cylinder heads, and more. These tools ensure that the parts achieve the required accuracy and surface quality. The following are common cutting tools used in the machining process:
Cylinder block and cylinder head processing
Drilling and reaming: Using drills and reaming tools to process cylinder holes is the basic step in engine block processing.
Milling: Use milling cutters for surface processing of the cylinder head and cylinder block, and milling of oil passages and cooling passages.
Grinding: Use a grinder and grinding head to precision grind the inner wall of the cylinder bore to improve surface finish and dimensional accuracy.
Crankshaft machining
Turning: Use turning tools to perform preliminary processing on the main journal and crankshaft journal of the crankshaft.
Grinding: The turned crankshaft is precision ground to ensure high dimensional and surface accuracy.
Piston and connecting rod machining
Turning: The outer circle of the piston and the small and large ends of the connecting rod are processed using a lathe.
Milling: Milling specific parts of the connecting rod, such as cutting the split surface of the big end of the connecting rod.
Grinding: The piston pin bore and connecting rod bore are ground to ensure precise fit.
Camshaft machining
Turning: Turning the basic shape of the camshaft.
Grinding: Cam and journal sections are precision ground to achieve the required shape and surface accuracy.
Gears and transmission components
Milling: Mill the blank of the transmission gear to form a rough shape.
Gear hobbing or shaping: Gear hobbing or shaping tools are used to produce precise tooth profiles on gears.
Grinding: Grind the gear after tooth profile processing to improve the accuracy and surface finish of the gear.
Other special processing
Thread processing: Use a tap or thread milling cutter to process parts that require threads, such as bolt holes.
Drilling and boring: Precise processing of oil holes, water holes, etc. to ensure smooth flow of fluids.
