How to cut the woodworking board forty-five degree angle

1. How to adjust the 45 degree angle cutting machine

45 degree angle cutting machine uses the linear motion mode of the worktable, applicable to the picture frame, photo frame, wood strips, furniture, plastic strips, aluminum profiles and door frames for cutting work, can be based on the computer set up the program to create a variety of patterns and drawings

program. It can make the movable table to ensure the smooth work during the cutting process. Its biggest feature is that it comes with an alloy saw blade, which makes a 45-degree angle with the contact point of the frame bar, so that it will not scratch the frame bar cutout when it comes into contact with the frame bar cutout that needs to be cut. Without this frame, it is easy to scrape the cut, resulting in scars at the cut, the cut is not smooth resulting in sealing when not sealed.45 degree corner cutting machine on the accuracy of the test is generally divided into three positioning accuracy, repeat positioning accuracy and reverse error.

45-degree angle cutting machine to get a good accuracy of the cutting angle, you must do a lot of tests to prove that its spiral support shaft is in the right precision and cut when the bearing preload.

From the analysis of the principle of closed-loop transmission of the 45-degree cutting machine, the error is mainly due to the feedback accuracy of the closed-loop angle grating (or angle encoder), the indexing accuracy of the transmission system, the transmission link of the backlash, the rotary axis of the matching error, the radial runout of the support bearings and rotary parts, the rotary distance (rotary coordinates of the center of rotation to the distance between the end face of the spindle) appears to be inaccurate measurements, and other factors. The consequences of factors.

And 45 degree cutting machine rotary axis of the matching accuracy of the error, to use a more appropriate fit tolerance and bearing preload to solve, but if the preload is too large for the rotary movement will bring additional power loss, so that the machine's rotary axis of the no-load start-up torque will become larger, affecting the dynamic performance indicators of the machine tool. So only through the selection of high-precision components to solve these problems.

2. A portable cutter with 45 degrees (cutting tiles) but just do not know how to use it to

You can not directly use the cutter's 45 ° to cut the tiles, because that is very difficult to grasp.

I'll give you a method here: make a shelf (as shown in the picture) with a carpenter's board, the length depends on the length of the tiles, about 20 centimeters longer than the tiles can be. Adjust the base plate of the cutter to a 90 ° angle with the cutting blade, the right side of the base plate with a small wooden square to do the limit, so that the cutter along the small wooden square and the tiles on the slope into a parallel direction of movement (cutting); the degree of this slope is about 50 ° or so, and not too big, can not make it 45 ° angle, so that the tiles on the cut out of the slope will be less than 45 °, conducive to the denseness of the two tiles spliced together! -Make sure the mouth is dense, there will be some gaps inside, but this is okay.

The ramp also has a small wooden square as a limit for the height position of the tiles, which is based on the width of the tiles, to the extent that the cutting blade just cuts the tiles to the thickness of the desired tile opening, but this is something you need to do a couple of adjustments to achieve. This small wooden square must be kept parallel to the countertop above, and as long as it is adjusted at the beginning, then the next is easy to operate - this wooden shelf can be used again and again.

To use it, make a straight line movement of the cutter from the front to the back, just be careful to keep the base of the cutter against the small wooden square on the right.
