What is the relationship between the smallest hole that a metal laser cutting machine can cut and the plate thickness?
The rapid popularity of metal laser cutting machines makes customers handy when using laser cutting machines to cut round holes. The metal laser cutting machine has become the best choice for cutting round holes due to its obvious advantages such as smooth section, changeable aperture, and flexible processing.
So what is the relationship between the smallest hole that can be cut by a metal laser cutting machine and the thickness of the plate? Generally speaking, whether it is imported or domestically made, the metal laser cutting equipment on the market can only cut 1:1 holes. The larger the better, the less capable equipment will have irregular round holes and too many breakpoints when cutting small holes. At present, the best imported equipment can achieve holes with 1/3 of the thickness of the board.
In fact, using a metal laser cutting machine to cut round holes is not as easy as imagined. Therefore, the following is the problem of cutting round holes to analyze possible difficulties and precautions:
1. The round hole is too small. Laser cutting machine cutting 1:1 holes is the best solution. The larger the hole diameter, the better the cutting. When laser cutting machines with insufficient capacity cut small holes, irregular round holes and too many breakpoints will remain.
2. The gas pressure is too large or too small. If the gas pressure is too high, the hole will burst. If the pressure is too low, the cutting edge will be rough and the burning will be serious. Choosing the right gas pressure is one of the reasons to solve the irregular cutting of round holes.
3. Servo motor parameters. Many parameters of the servo motor are related to arc motion. The parameters are not suitable. The mismatch of x and y axis motions will cause ellipse or irregular graphics in the cutting hole.
4. The precision of the lead screw or guide rail is not enough. Some small factories have low technical strength and low level of workers, and the precision of the laser cutting machine produced cannot reach 0.1mm, so the precision of the circular hole cut does not meet the requirements.
