Introduction: In the production process of aluminum alloy doors and windows with thermal breaks and bridges, there are occasions where it is necessary to cut short materials of 400 mm or less or even ultra short materials of 200 mm or less. However, the current popular models of aluminum double-head cutting saws have not been effective. To solve this problem, how have workers been cutting ultra-short materials all the time?

Aluminum double-head saw short material cutting solution

During the production process of aluminum alloy doors and windows with thermal breaks and bridges, there are occasions where it is necessary to cut short materials of 400 mm or less or even ultra short materials below 200 mm. However, the current popular models of aluminum double-head cutting saws have not been able to effectively solve this problem. One problem. One reason is that the situation of cutting short products in actual production is relatively rare, so that equipment manufacturers do not think it is necessary to spend a lot of energy and financial resources to study and solve this problem. On the other hand, the reason is that this problem is really not easy to solve. Devices to achieve short cuts often affect the efficiency of normal size cuts.

So how have workers been cutting ultra-short materials? Can only be solved by what we call the stupid way to solve, to Jinan Nakai Windows and Doors Equipment Co., Ltd. production of aluminum ordinary double-head precision cutting saw to cut the requirements of both ends of the 45-degree angle of 150mm length of ultra-short material as an example of the specific operation method as follows:

In the first step, the 45° angle of one end of the profile is first cut with the double-headed saw's left head, that is, the fixed head, and the right head of the double-head saw is not moving.

In the second step, use a metric ruler to measure 150mm from the cut-out vertex of the 45-degree angle, and use a pencil to mark the end point.

The third step is to set the double-headed saw to the right nose at a single angle of 45 degrees.

The fourth step is to place the marked profile on the worktable of the right hand head, visually observe the mark and the left edge of the saw blade coincide with the eye, and then the cylinder presses the profile and starts the right hand head to complete the cutting.

The fifth step is to use a metric rule to measure the cutting error of the cut profile. The length error is preferably ≦±0.5mm.

Although the use of short-cut materials is relatively rare, it is believed that in the near future, under the encouragement of the great craftsman spirit, under the constant efforts of the door and window equipment manufacturers, a simple and effective practical device will eventually be developed to solve this problem. .
