As you know, the traditional flat knife such as alloy knife, shaping knife has the following problems: Burning of the cutting edge: when the cutting edge is worn or the feed is temporarily stopped, the cutting heat will produce burn marks on the cutting surface. Tool passivation and stability: The increase in tool temperature increases…
Extrusion punch is a mold accessory made from steel materials suitable for processing, such as high-speed steel, powder high-speed steel, tungsten steel, and other molds. Suitable for processing industries such as cold heading, cold extrusion, stamping, hydraulic pressure, and injection molding. Punch bars are important accessories in cold heading molds, which can be divided into…
Due to the large increase in domestic demand for stainless steel products, stainless steel production has also increased significantly. The global growth rate of 5% per year has almost doubled in the past 10 years. With the increase of stainless steel products, the problems of stainless steel processing and manufacturing are becoming more and more…

With the development of technology, discarded spiral cutter head has gradually replaced traditional flat knives and four-sided planers. In the near future, it will be gradually popularized in the woodworking machinery industry. At present in Europe and America, it has become the standard tool for woodworking machinery, which has following advantages. Spiral blade surface The high-precision…
The milling cutter is the most important tool of CNC machine tools. There are many kinds of milling cutters we use in our daily life, and end mills are the most common. End mills can be divided into left-hand milling cutters and right-hand milling cutters. Do you still have no idea of milling cutter turning…
The stability of woodworking milling cutter affects the machining accuracy and surface quality of the workpiece, so in the process of wood milling, we should try our best to improve the stability of milling cutter. Because during the milling process, under the action of external forces will produce vibration and deformation, and then affect its…
Today’s nails are typically made of steel, often dipped or coated to prevent corrosion in harsh conditions or to improve adhesion. Ordinary nails for wood are usually of a soft, low-carbon or “mild” steel (about 0.1% carbon, the rest iron and perhaps a trace of silicon or manganese). Nails for concrete are harder, with 0.5–0.75% carbon. from wikipedia Nails…
