The Workpiece Placement Of CNC Machine (part 2)

Apr. 21, 2019

There are various installation methods for machining parts on various machine tools. Installation methods can be divided into three types: direct alignment, line alignment and fixture installation. Below CNC Customized Aluminum Parts Manufacturer would like to give you a detailed introduction.

1. Find the right method directly

In this method, the correct position of CNC machining workpiece on the machine tool is obtained through a series of attempts. The specific way is to load the CNC machining workpiece directly on the machine tool, with the dial gauge or the scriber on the scriber, to visually correct the correct position of the workpiece, while checking and aligning, until the requirements.

The positioning accuracy and speed of direct alignment method depend on alignment accuracy, alignment method, alignment tools and workers' technical level. Its disadvantage is that it takes much time, low productivity, and to operate by experience, high technical requirements for workers, so only used in single, small batch production. In addition, when the positioning accuracy of the workpiece is required to be higher, for example, when the error is less than 0.01-0.05mm, it is difficult to meet the requirements by using the fixture (because of its own manufacturing error), it is necessary to use precision measuring tools, and by the workers with a higher technical level with direct alignment to locate, in order to achieve the accuracy requirements.

2. Line to find the correct method

This method is a way to find the workpiece by drawing the line on the blank or semi-finished product on the machine tool and make it get the correct position. It is obvious that this method requires an additional marking process. The drawn line itself has a certain width, and there is a marking error when marking, and there is an observation error when correcting the position of CNC machining workpiece, so this method is mostly used for the production of small batch, low precision of the blank, and large CNC machining workpiece should not be used in the rough machining fixture.
