This series of high-speed and high-efficiency CNC gear hobbing machine adopts the principle of generation method to realize the hobbing of cylindrical spur gears, cylindrical helical gears (shaft gears, disc gears), worm gears, small taper gears, drum gears, splines, sprockets, synchronous pulleys and other specific tooth types. The main castings of the CNC gear hobbing machine tool are designed with double-wall and high-rib plate structure, and through finite element analysis, it can not only ensure the overall rigidity of the CNC gear hobbing machine but also take into account the stability of the CNC gear hobbing machine. This series machine Received unanimous praise from Chinese and international customers.
• The CNC gear hobbing machine has three configurations of 5-axis, 6-axis and 7-axis for option.
• The cutter bar adopts hydraulic pressure to automatically tighten and relax, which is convenient for users to change tools and shortens the time for tool adjustment.
• The X and Z axes of CNC gear hobbing machine adopt high-rigidity rolling linear guide rails, which make the guide rails of the CNC gear hobbing machine maintain long-term accuracy and long service life, and facilitate later maintenance.
• The C-axis of CNC gear hobbing Machine is driven by a high-precision motor, which ensures the indexing accuracy of the worktable and provides strong cutting force for gear hobbing.
• The Y-axis of CNC gear hobbing Machine is directly driven by a servo motor to ensure the precision of the tool shifting and prolong the service life of the tool, while ensuring the overall cutting rigidity of the CNC gear hobbing machine.
• The top guide rail of CNC gear hobbing Machine is a high-precision line rail, and is equipped with an oil cylinder to drive the top movement, ensuring the movement accuracy of the top guide rail and the convenience of CNC gear hobbing machine adjustment.
• The processing area of CNC gear hobbing machine is equipped with stainless steel inner protection, which completely separates the processing area and facilitates chip removal.
• Precise secondary tooling setting device for precise secondary hard scraping of hard tooth surface is for option for CNC gear hobber.
•
Equipped with a rotating top tailstock center, avoiding the wear of the center hole when using the fixed tailstock center, and enhancing the rotation accuracy of the tailstock center.
