Abstract

The invention discloses a machining method for an R groove in a guide plate of a marine diesel frame. On a numerically controlled planer-type milling machine, a compound boring-milling tool is mounted on a shock-proof tool holder connected to a power spindle accessory, and is controlled to move radially or axially through a numerically controlled program instruction, so as to fulfill automatic cutting of the R groove. The compound boring-milling tool comprises a tool body, a plurality of tool holders and a plurality of blades, wherein the tool holders and the blades are fixed at the periphery of the tool body and uniformly distributed; the blades are mounted on the tool body through the tool holders, and are rhombus-shaped; the angle of the tool noses of the blades are 55 degrees; the pointcut of each tool nose in the R groove for cutting is small, so as to realize overcutting prevention of the blades, low tremble of the tool and high degree of finish of a machined surface. The machining method has the advantages that efficient continuous automatic machining is realized; tremble during machining is reduced effectively; no machined trace is formed; the degree of finish of the machined surface is improved; the service life of the tool is prolonged; the machining cost as well as the labor intensity is reduced.

Description

technical field [0001] The invention relates to metal cutting processing of marine diesel engine parts, in particular to a processing method and cutting tool for a guide plate R groove of a marine diesel engine frame, and belongs to the technical field of diesel engine manufacturing. Background technique [0002] The frame is one of the important parts of the marine diesel engine, please refer to figure 1 , the frame 5 is provided with multiple guide plates 6 for multiple cylinders, and an R groove 1 is provided at the lower end of the two guide plates 6 on the exhaust side and the fuel side of each cylinder, please refer to figure 2 , the R groove 1 is a 1 / 4 arc of R50, recessed into the middle of the two guide plates 6 by 1mm. The number of the R grooves 1 is large, the surface finish is high, the positions distributed on the frame 5 are staggered and complicated, and the surface of the guide plate 6 is wide, so the processing is difficult. The original traditional proc...
