Operation tips for Polar cutting machine

During the process that the material is manually placed on the paper cutter and subsequently cut, the skills and observation of the operator play a decisive role. It is not an easy task to accurately put the material into the angle formed by the rear block gauge and the side block gauge. The operators who deal with paper every day have accumulated a lot of experience and are very clear about what problems may occur. For example, once the material is bent, uneven or has internal stress, it is quite difficult for the operator to accurately complete the cutting task without the necessary auxiliary equipment.

How to compensate the skewness of the printed image?

To achieve fine cutting, the accurate placement of the material to be cut is undoubtedly very important. Suppose you want to cut the printed product, usually, the material should be placed on the paper cutter in the same way as it is on the printing machine.

If the printed image on the paper is skewed, and the operator wants to cut the image straight, then he should place the material to be cut at a certain angle, or put a piece of cardboard between it and the rear stop to try to make up. Loss at the skew, but doing so is cumbersome, time-consuming, and inaccurate.

The use of a rotating backstop can compensate for the skewed printed image and also make this job easy and efficient. The function of the back gauge of the rotation of the Pola knife greatly simplifies the operation. You can set the rotation back gauge according to the cutting size while the cutting program is running, and automatically activate the Teach-in function. The cutter control system recognizes the commands entered by the operator and automatically integrates them into the current cutting program, for example, aligning the first-knife cutting with the printed image precisely in parallel. When turning the material, be sure to place the edge just cut against the side stopper.

How to align the material to be cut?

When the operator places the material to be cut against the back gauge, if the top paper is raised, they will move upwards, which will result in cutting errors. The operator usually bends or rolls the corners of the top layer of paper, which can make the paper slightly smoother, but if improperly operated, it will damage the paper and make them unusable. Or, if the paper is wrinkled, it will cause problems for folding or packing.

The paper clamp at the rear stopper can ensure that the top paper is flat and snug, so that the material to be cut can be placed close to the rear stopper. While the paper clamp is working, the operator can also push the material back to the back gauge tightly and accurately. Rollers are also installed on the paper clamp to manipulate the top paper.

How to align the sides of the material to be cut?

Operators often find it difficult to fully align the material with the rear gauge. If the side of the material bends unevenly, it will continue to move in front of the rear stop. The first cut is the key factor that determines the final quality of the product, but it is often the biggest obstacle facing the operator.

The programmable Fixomat gauge line is used so that the material to be cut does not completely contact the rear gauge, but partially contacts the rear gauge. In this way, paper placement is safe and convenient. Now, you can cut under the guidance of the rule line. Pola knife Fixomat function can also automatically adjust the position of the rear block gauge. Regardless of whether the cutting program carries the Fixomat function, the cutter control system can always adjust the back gauge to the correct position, and the operator no longer has to work hard to correct the cutting size.
