What is the material of the sewing machine knife?

The selection of the material of the sewing machine knife is usually based on whether the roughing or finishing process is involved. Of course, this is only one aspect of the consideration of high-temperature alloy turning. In high-temperature alloy turning, plastic deformation, as a form of wear, is always an existing risk. It is necessary to improve the material of the sewing machine knife to avoid or reduce it. On the other hand, groove wear is another main form of wear, which is mainly determined by the size of the entry angle and the shape of the sewing machine knife used. Therefore, the choice of material is largely based on the shape of the sewing machine knife.

How to install sewing machine knife correctly?

When using cemented carbide for cutting operations, it is very important to install the sewing machine knife correctly. If the contact position between the cutting edge and the workpiece is not correct, the sewing machine knife may chip or damage the workpiece, and sometimes even damage the machine tool. The two most common problems are that the sewing machine knife is not perpendicular to the workpiece or the cutting edge is installed too high or too low relative to the center axis of the workpiece. They affect the life of the sewing machine knife, chip control and whether it can maintain a vertical and smooth cutting. A greater impact will also result in convex and concave surfaces on the surface of the processed parts. If these problems are very serious, sewing machine knife will fail. To ensure that the sewing machine knife is perpendicular to the workpiece, the operator should follow a simple installation process.

What is the importance of installing sewing machine knife correctly?

In the installation of sewing machine knife, another major consideration is the position of the cutting edge relative to the axis of the workpiece. Incorrect installation of the sewing machine knife will cause a series of problems, the most common of which are premature tool wear and sudden failure, poor chip form, poor side roughness and vibration. Since it is sometimes difficult to ascertain the actual position of the cutting edge, these problems will be further exacerbated. These phenomena often occur on old manual and automatic machine tools. Most cemented carbide blades designed by the manufacturer must be installed slightly higher than the center axis of the workpiece during use. This position facilitates the use of welding chip breakers and ensures that the sewing machine knife is reliably clamped on the tool bar.

The sewing machine knife have been widely used in daily life and industrial production.
