CNC Vertical Deep-Hole Grinding Machine

This is a special model dedicated to deep hole grinding. The vertical structure allows easy setup of long workpiece incl. quick centering and less deformation, and enables accuracy improvement in ID roundness, concentricity, cylindricity, surface roughness, etc.
It provides the optimal solution for major parts of construction machinery; a typical example is hydraulic breaker cylinder for rock breaker. The piston inside of the cylinder moves up and down by hydraulic pressure, where the accuracy of cylinder ID directly affects the smooth piston movement and boosts the power of the rock breaker.
