Aluminum window especially the thermal break window is more and more popular in today’s world. People love it because of its excellent thermal insulation properties. Besides of the good design and high-quality materials(aluminum profile, glass, strips, sealant, etc), what else make the thermal break window function so well? The answer is the way to make the windows.

To make aluminum windows, we must need aluminum window machinery including aluminum profile cutting saw, crimping tool, aluminum punching machine, aluminum bending machine, end milling machine an so on. For all the machines above, the aluminum profile cutting saw is the most important one. Usually, the window jamb and sash profiles are jointed at 45degree angle. And the mullion profiles are connected to the jamb at 90 degree. So, cutting 45 degree and 90 degree angle is the basic function required for the cutting saw. The double head miter saw is made for this purpose.

JMD is the leading manufacturer of aluminum window machinery in China. We have 2 models of double miter saw optional:

1. LJJ2AS-500X4200, CNC controlled. The right machine head can move automatically to reach the cutting length. Cutting length can be preset through the touch screen. It’s easy to operate, especially when you have multiple cutting lengths.

2. LJJ2AX-500X4200, Non-CNC. The right machine head should be manually moved to reach the cutting length. The real cutting length will be displayed by a digital screen. Compared the the CNC saw, it is more simple and stable. More importantly, its price is not high.

Which saw will you choose? Feel free to contact us if you’re interested.

First of all, aluminum window machines are mainly used to process and make aluminum doors & windows, while UPVC window machines are mainly used to process and make UPVC doors & windows.
In terms of specific classification, there are two types of door and window machines: cutting machine and milling machine.

When it comes to this, many people may ask, since they are both cutting saws, can the two be used in common? From the perspective of power alone, the cutting saw of aluminum window equipment can cut UPVC, while the cutting saw of UPVC window equipment cannot cut aluminum profiles.
But we also needs to know one thing. When using the aluminum cutting saw to cut the UPVC profiles, you must remember to replace the saw blade. If you continue to use the previous saw blade to cut the aluminum profile, then it will greatly reduce the service life of the equipment.As when it cuts UPVC profiles, the saw blade will heat up due to friction, and the UPVC profiles will stick to the saw teeth, and the cutting effect will also be greatly reduced.
