The formulation of the machining process of the cast iron scribing plate can generally be divided into two steps. The first is to formulate the process route of cast iron scribing and plate processing, and then determine the equipment used in each process, process size and process equipment, working hours quota, cutting specifications, etc. These two steps are interrelated and should be analyzed comprehensively.

The formulation of the cast iron slab process route is to formulate the overall layout of the process. The main task is to select the processing method of each working surface, determine the processing sequence of each working surface, and the number of processes in the entire process.

 

The general principles for establishing a process route for cast iron scribing plates are as follows.

 

1. Process the datum surface first

During the processing of the part, the surface as the positioning reference should be processed first, so as to provide a precise reference for the subsequent processing as soon as possible. It is called "benchmark first".

 

2. Divide the processing stages

Surfaces with high processing quality requirements are divided into processing stages, which can generally be divided into three stages: rough processing, semi-finishing and finishing. The main purpose is to ensure the processing quality; facilitate the rational use of equipment; facilitate the arrangement of the heat treatment process; and facilitate the discovery of blank defects.

 

3. Hole first, then surface

For parts such as square boxes, brackets and connecting rods, the plane should be processed first and then the holes should be processed. In this way, the holes can be positioned on the plane to ensure the position accuracy of the plane and the holes, and it is convenient to process the holes on the plane.

 

4. The main surface finishing (such as honing, grinding, fine grinding, etc.) should be carried out at the last stage of the process route to prevent the finishing surface from being damaged due to the transfer and installation between processes.
