In the last few articles, Huazhou Xiaoguo gave a brief introduction to the grinding of CNC band saw blades. Today’s article describes some necessary work that needs to be done before grinding CNC band saw blades. Let’s take a look at it together. Look, what should we do before grinding the saw blade.

CNC band saw machine The saw blade needs to be leveled, tensioned and straightened before grinding band saw blade . Leveling means surface. In CNC band saw blade leveling refers to removing the unevenness (ridges/dents) in the band saw blade. This is usually the first step in a sharpening job. After the linear ruler is positioned, the bump can be "knocked out" with the help of a "ball-peen or cross-peen hammer." At this time, the weight of the hammer must match the thickness of the saw blade. Below are some reference values on saw blade repair compiled by Huazhou Xiaoguo based on the Internet and experience: The following are worth collecting.
If the thickness of the saw blade is ≤ 1.65 mm, the weight of the hammer is 1250 g
If the thickness of the saw blade is 1.65 mm, the weight of the hammer is 1500 g
When using the hammer, the hitting surface should be soft and rounded, so as not to leave any damage on the band saw blade. The service life of the imprint may be adversely affected. We are tensioning or stretching to extend the central area of the band saw blade. Use roller press to do this work by roller pressing. After passing through the roller press, the central area of the saw blade of the CNC band saw machine expands, and the upper and lower edges of the saw blade become shorter relative to the central area. Next, we need to remove the compressive stress when installing the saw blade on the roller of the saw machine, and the middle area of the saw blade is arched. This prevents the saw blade from moving back and forth on the mostly convex roller sliding surface. If the stress effect is correct when we operate the CNC band saw, the saw blade has the following characteristics:

1. The sawtooth edges are tight and very smooth and quiet during operation.
2. The saw blade is properly mounted on the rollers and withstands the loads caused by high feed rates.
3. The saw blade has no tendency to deviate. If the stress is used correctly, the quality and accuracy of the cutting CNC band saw machine blade can be maintained. After the
CNC band saw is ground, the saw blade must be straightened. When we straighten the CNC band saw blade, the back of the band saw is rolled into a slightly convex arc. Therefore, the balance band saw expands outward during use. If the tooth groove is ground again, it will also cause the saw tooth baseline to extend to the top of the saw tooth. Therefore it is necessary to check the condition of the entire back side of the saw blade.

A good enterprise cannot do without the help of machinery. In the past, measuring, straightening, tensioning and leveling: manual operations that used to consume a lot of labor now only require one clamping operation. Just one step. Huazhou Xiaoguo believes that the future development of enterprises will still be inseparable from the use of machinery, and may even replace workers in some aspects.
