Production process of TCT saw blade gear grinding machine production line
1. Trimming: The TCT head saw blade production line uses a fixed-shape hard alloy blade. One side of the cold-rolled alloy steel strip is cut into a plane as a welding surface to facilitate the subsequent welding process. The other side is cut into an arc shape as a back bottom. For certain specifications of cold-rolled alloy steel strip, it needs to be cut to a fixed width.
2. Electron beam welding: Using advanced imported equipment, the accelerating and focusing electron beam is used to bombard the contact surface of the high-speed steel wire and the cold-rolled alloy steel strip after being trimmed in a vacuum. When the electron beam strikes the workpiece, the kinetic energy is converted into the required thermal energy to weld the contact surfaces together. It is a high-energy density bimetallic band saw blade welding technology.
3. Laser welding: An efficient and precise welding method using advanced imported equipment and welding with a high energy density laser beam as a heat source, which can replace the electron beam welding of bimetal composite steel strips.
4. Spheroidizing annealing: The welded composite steel strip is placed in a well annealing furnace or bell-type annealing furnace, and a suitable annealing process is used to make the carbides in the tooth material, back material and weld seam spherical. To facilitate subsequent cold processing.
The main uses of abrasive tools for alloy saw blade gear grinding machines:
Abrasive tools (grinding wheels, abrasive belts, whetstones, or abrasives, etc.) used for gear grinding machines as tools for cutting the surface of workpieces are collectively referred to as grinding machines. Universal tool grinders, grinders can process a variety of surfaces, such as internal and external cylindrical and conical surfaces, planes, gear tooth surfaces, spiral surfaces and various molding surfaces, etc., can also sharpen tools and cut, etc.
The process range is very wide. Because grinding is easy to obtain high machining accuracy and good surface quality, grinding machines are mainly used for precision machining of parts, especially for hardened steel parts and special materials with high hardness. Dongguan Gongda Precision Machinery Co., Ltd. has been committed to the production and research and development of tool grinders, and each product has undergone strict quality management, and its quality has been affirmed by domestic and foreign customers.
Lathes are mainly used for machining various rotating surfaces and end faces of rotating bodies. Such as turning inner and outer cylindrical surfaces, conical surfaces, ring grooves and forming turning surfaces, turning end faces and various commonly used threads, equipped with technological equipment can also process various special surfaces. Drilling, reaming, reaming, knurling, etc. can also be performed on a lathe.
Milling machine A machine with a wide range of applications. It can process planes (horizontal planes, vertical planes), grooves (key grooves, T-slots, dovetail grooves, etc.), tooth-splitting parts (gears, spline shafts, sprockets, spirals) on the milling machine. Shaped surfaces (threads, spiral grooves) and various curved surfaces. In addition, it can also be used to process the surface of rotary bodies, internal holes, and cutting work.
When the milling machine is working, the workpiece is mounted on the table or an indexing head and other accessories. The rotation of the milling cutter is the main movement and the feeding movement of the table or the milling head is used to obtain the required machining surface. Due to the multi-tool intermittent cutting, the productivity of the milling machine is high.
