This machine implements the Q/AJL 003-2014 standard. It is used for the grinding of long blades and the grinding of various cutting tool angles. It can also be equipped with super-precision auxiliary grinding heads according to customer needs, especially suitable for grinding super-hard materials. The knife edge is mirror-finished, which is more sharp and abrasion resistant, and achieves a flawless knife edge. The grinding machine integrates humanization operation, easy maintenance and grinding precision. The high-rigidity integral bed, equipped with linear guide rail, runs reliably and stably. Precision and high rigidity grinding head, sharper grinding. The servo system feeds vertically, and the instructions are accurate and reliable. It can realize timing and quantitative grinding. The grinding head moves infinitely adjustable speed, which is suitable for grinding with different technological requirements. The lubrication system realizes automatic timing and quantitative lubrication, and can control the length of time and flow rate from the control system. It is suitable for large-scale wood processing, plastics, printing, paper processing, blade manufacturing and other factory sharpening applications.
