Gear Hobbing Machine
The model YKB3150 and YKB3180 are 2-axis CNC gear hobbing machines: X axis-radial feed motion; Z axis-axial feed motion. On the principle of generating method, the machine is capable of cutting cylindrical spur and helical gears, crowning and slightly tapered gears, as well as sprockets and wormwheels. The machine is best suitable for heavy-truck, mining machinery, ship and motorcar industries in jobbing or batch production.
With vertical design, the worktable moves to realized radial feed motion. CNC spindles are driven through preloaded ballscrews. Which can cut crowning and slightly tapered gears by axial and radial coordinated control. The function of automatic hog shifting reduces tool’s wear and prolong the tool’s service life.
