How to remove chips during the operation of the laser cutting machine?

When using a laser cutting machine for cutting work, there will be some iron filings that are difficult to clean, but you must clean it up to avoid clogging. Later, if you have an unexpected failure during use, you can also check whether it is related to this.

Because the desktop laser cutting machine adopts the built-in cutting table design, the cutting iron filings will be placed inside the cutting table and difficult to clean in the daily cutting process. But from the perspective of equipment use, timely and effective chip removal is helpful for the machine to perform better operation. So how does the desktop laser cutting machine CNC machine tool perform chip removal operations?

The self-developed Xunfeng T series desktop laser cutting machine is designed with an automatic chip conveyor (also known as chip conveyor), which is controlled radially by a computer through an auxiliary control device, and is mainly used to discharge the cutting of the machine tool during processing. . Chip removal is divided into two ways: automatic timing chip removal and manual non-time chip removal.

The so-called timing automatic chip removal, that is, the chip removal instructions are first programmed into the program during the machining process to make the chip removal at a fixed time. The so-called manual irregular chip removal means that the operator will follow the instructions from time to time during the machining process. The chip removal situation is manually operated (in NDI mode) to time the chip removal. In order to allow users to have a more comprehensive understanding of the features of different types of desktop laser cutting machine chip removal function design, below we will introduce and explain several types of common chip removal devices.

1. Spiral chip removal device

This device uses a motor decelerating device to drive a cage-type screw rod installed in the groove. This is also the chip removal design method adopted by the current Xunfeng T series desktop laser cutting machine. Its working principle for:

When the spiral rod is working, the cutting in the groove is pushed by the spiral rod to move forward continuously, and finally discharged into the cutting collection box. The spiral rod has two structural forms, one is rolled into a spiral spring with a flat steel strip; the other is a spiral steel plate on the shaft. This device occupies a small space and is suitable for installation in a narrow position between the machine tool and the column. The spiral chip removal device has a simple structure and good performance, but it is only suitable for horizontal and small-angle inclined straight line transportation and cutting, and cannot be inclined, lifted, and turned to remove chips at a large angle.

The installation position of the chip removal device is generally as close as possible to the cutting area of u200bu200bthe tool. For example, the chip removal device of the lathe is under the rotating workpiece, and the chip removal device of the milling machine and machining center is installed on the back flume of the bed or on the side of the worktable. , In order to simplify the structure of the machine tool and chip removal device, reduce the area of u200bu200bthe machine tool, and improve the efficiency of chip removal. Excluded cuts generally fall into the cutting collection box or trolley, and some are directly discharged into the workshop chip removal system.

Two, plate connection type chip removal device

The device uses a rolling sprocket to pull a steel flat chain belt to run in a closed box, and the cutting chain belt is taken out of the machine tool. This device can eliminate cutting of various shapes and has strong applicability. All kinds of foundations can be used. When used on a lathe, it should be integrated with the machine cooling box to simplify the structure of the machine tool.

Three, scraper type chip removal device

The transmission principle of this device is basically the same as that of the plate link type, except that the chain plate is different. It has a scraper chain plate. This device is often used for short cutting of various materials, and has a strong chip removal ability. Due to the large load, a higher-power drive motor is required.

The above is a detailed introduction to the chip removal device during the operation of the laser cutting machine. You can refer to the above article to operate it in the later use process.
