heavy duty manual gear hobbing machine

heavy duty manual gear hobbing machine 

◊ Raise height of vertical column and increased stroke effectively expand the working range.

◊ Mechanism with electric tool leap allows longer hob and greatly increases service life of the cutting tool.

◊ Worm gear of a high precision over five grade features long service life and steady accuracy.

◊ Traditional bearings along the hobs are replaced with rolling bearings to enable greater speed of the tools.

◊ External support of the small column tailstock adopts the hinge structure and can be easily opened outward, convenient to hang components of large diameters.

Y3180/Y3150 series gear hobbing machine is fixed by vertical column and adopts the traditional layout of horizontally moving working table, suitable for processing cylindrical gears, worm wheel and short spline shaft in bulk, in package, or in single workpiece. The machine has the following characteristics:

1. Raised height for vertical column and increased stroke: The vertical column is made higher (180/130mm increased axial stroke in head slide than Y3180/Y3150 of the same kind) to enable processing of larger tooth width.
2. Service life of cutting tools is increased by electric tool leap. The longest stroke reaching 180mm, such electric tool leap takes longer hob and greatly increases life the hob.
3. High precision and long service life: The machine adopts the worm gear of a high precision over five grade and uses bronze alloy material which is of high abrasion resistance, enabling long service life and steady accuracy.
4. Higher tool speed allowed: Rolling bearings replace the traditional bearings along the hobs to allow greater rotating speed of the tools.
5. Backlash balancing cylinder is involved as the tool post moves in the axial direction, effectively reducing the space between lead screws and eliminating vibration.
6. Convenient hydraulic powered structure reduces the non-cutting time as well as the times to use the cutting tools.
7. External support of the small column tailstock adopts the hinge structure and can be easily opened outward, convenient to hang components of larger diameters(Y3180).
