Everyone’s workshop is estimated that there will be a treatment center. errors as much as possible errors.
So, how can we judge the accuracy of a machining center?Let’s talk about 4 aspects below.
1. Positioning of the vertical treatment test:
The testing pieces must be located in the middle of race X, and the Y axis and Z must be placed in the appropriate position adapted to the test parts and the positioning of the luminaire and the length of the length of the tool . When there are specific requirements for the positioning of the test parts, it must be stipulated in the manufacturer and the user contract.
2. The fixing of the test part:
The test parts must be easily installed on a dedicated luminaire to obtain the maximum stability of the tool and the lighting. The installation surface of the lighting and test parts must be straight.
The parallel degree of the test parts installed on the surface and the tightening surface of the luminaire must be inspected. The appropriate maintenance method should be used to allow tools to penetrate and treat the central hole. It is recommended to use a fixed test part to avoid interference with the tool and the screws. The total height of the test part depends on the selected method.
3. The material, the knife and the cutting parameters of the test part:
The cutting materials and tools and cutting settings of the test part are selected according to the protocol between the manufacturer and the user, and the recommended cutting parameters must be saved as follows:
1) The cutting speed: the cast iron part is around 50 m / min;
2) Characteristics: approximately (0.05 ~ 0.10) mm / teeth.
3) Cutting depth: All milling processes must be 0.2 mm at the depth of radial cut.
4. The size of the test part:
If the test part is cut several times, the shape of the shape decreases and the diameter of the pores increases. To honestly reflect the cutting precision of the treatment center. The test parts can be used several times in the cutting test, and its specifications must be kept at less than 10% of the characteristic size given by this standard. When the test part is used again, a thin layer cut should be performed to clean the entire surface before performing a new fine test.
It is estimated that you will encounter another problem in the process of using the treatment center. Buy us parallel imports?
The precision of treatment of the parts of the treatment center is generally due to the adjustment of the dynamics of the food between the axis according to the error, or because of the wear of the different axes, or due to the wear, the axis of the axis of the axis of the machine-tool has changed (like the barbaric space, the distance from a snail, the changes of character from the snail distance, the axial movement , etc.). It can be resolved by re-adjustment and compensation for the modified difference.
When the dynamic monitoring error is too large and the alarm is alarmed, it can be checked: if the speed of the servomotor is too high; Is the corresponding servo driver normal?
If the treatment accuracy caused by poor treatment accuracy during the tool-machine may be that the addition and the deceleration time can be too short and the speed change time can be prolonged appropriately; The screw is loose or rigid. The stem positioning accuracy is not good, or poorly compensation due to the screw difference will cause a round degree error to generate a time limit.
It turns out that the precision of the tool-tool has so much knowledge.
But there is another saying in the people: the great precision is guaranteed by others. It is said that the most precise machine tools in the world are calibrated by people. According to this declaration, we can use components with relatively high precision to assemble incredible treatment machine tools.
