When die-casting parts made of aluminum alloys, there is a significant amount of error that can occur, and the aperture is only getting larger. The experiment was considered to have been successful when it was discovered that the control swing fell within the bounds of the acceptable tolerance range. In addition, you should select a cutting fluid that has a good performance when cutting. Bearing, readjust the floating chuck, adjust the coaxiality a356 Aluminum Alloy, and pay extremely close attention to the operation that needs to be carried out.

1) The factors that contributed to it

It has been determined that the main deflection angle of the reamer does not meet the requirements, the design value of the outer diameter of the reamer does not meet the requirements, the cutting speed does not meet the requirements, the feed rate exceeds the requirements, and the cutting fluid that is being used is not appropriate.

2) A Few of the Possible Responses

Modify the outer diameter of the reamer; increase the cutting speed appropriately; decrease the feed rate appropriately; increase the main deflection angle appropriately; select an oily cutting fluid that possesses a high level of lubrication performance.1) What Are the Fundamental Reasons Behind It?

The reamer is too long and does not have sufficient rigidity, which causes vibration during the reaming process; the main deflection angle of the reamer is too small; the reaming cutting edge is narrow; the reaming allowance is off; there are notches and cross holes on the surface of the inner hole's surface; there are blisters and pores on the surface of the hole's surface; and there are notches and cross holes on the surface of  a356 Aluminum Alloy the hole itself. A malfunction of the machine is possible as a result of all of these issues. In addition, when the hole is being pre-machined, qualified reamers should be selected to control the hole position tolerance, and cutting tools should have unequal tooth pitches. 

This is done so that the hole will be precisely positioned within the tolerance range. When reaming more precise holes with an equal pitch reamer, the spindle clearance of the machine tool should be adjusted, the matching zinc alloy die casting factory clearance of the guide sleeve should be increased, or an appropriate clamping method should be used to reduce the clamping force. Alternatively, the clamping force could be reduced by using an equal pitch reamer. Alternatively, a clamping force reduction could be achieved by employing the use of an equal pitch reamer.

It is possible to see distinct edges that run the circumference of the hole on the interior surface of the aluminum alloy die-casting hole that surrounds the hole. There are a number of factors that contribute to this issue, including an excessive reaming allowance, an excessive spindle swing, an excessive number of pores and blisters on the surface of the workpiece, an excessive clearance angle of the reamer cutting part, and an excessive width of the reaming cutting edge.

The rate of cutting is too fast, the cutting fluid that was used was inappropriate, the main deflection angle of the reamer was too great zinc alloy die casting factory, and the reamer's cutting edges were not aligned on the same circumference as one another.

The speed at which you are cutting should be slowed down, the cutting fluid should be chosen according to the material that you are working with, the main deflection angle should be adjusted appropriately, and the reaming cutting edge should be appropriately sharpened. Last but not least, make sure that the reamer is regularly replaced and that it is ground when it needs to be sharpened. The state of the land in this area is getting worse over time.
