Shaper is a type of machine which, using hydraulic power, provide linear relative motion between the workpiece and single-point cutting tool to a linear path. Under high pressure, oil is pumped into the piston-fitted operating cylinder. This machine gives the following advantages.
Advantages of hydraulic shaper :
- The cutting speed and return speed of this shaper is practically constant throughout the stroke thus work done is uniform during the cutting stroke.
- The reversal of the ram is obtained quickly without any shock as the oil on the other end of the cylinder provides cushioning effect.
- An infinite number of cutting speeds may be obtained and its control is also easier. speed range varies from zero to the maximum value.
- Because of the high rate of return speed, a greater number of cutting strokes may be available within the range of cutting speed.
- The relief valve ensures safety to the tool and the machine when the machine is overloaded.
- Wide range of speed can achieve by controlling the fluid flow rate to shaper ram.
- Shock and vibration levels can reduce.
- Higher load-carrying capacity.
- Fluid on both sides of the ram provides a cushioning effect.
- Highly efficient.
