SLOTTING AND PARTING MACHINE AND WOOD RACK CUTTING MACHINE WITH WORM DRIVE TABLE
Wooden racks are either manufactured conventionally by using jig saw cutters which is time consuming and inaccurate hence there is a need for a special purpose machine to produce components as shown below.
1. Straight racks produced if cutter head is at 90 degree.
2. Gear racks can be cut by inclining the cutter head.
3. Slotting and grooving operations can be performed on same machine.
4. Small components can be slit.
5. Fast rate of production.
6. Robust worm drive is self locking hence no backlash while cutting.
7. Low cost of production.
8. Low running cost.
9. Lesser initial investment in special purpose machine.
