Detailed Product Description

T8590A/T8590B Valve seats boring machine is an extremely reliable machine whose design to repair various type of engines valve seats ring. Adopted rectangular guideway with high rigidity. Machine head can be moved up and down automatically, easy adjustment and simple operation. Equipped a guide shaft with corresponding size, the machine can repair the valve seats ring with diameter 20-90mm and working conical angle 30°,45°or 60°, the air-floating worktable clamp the workpiece and freely move.The high precision universal boring bar is attached to ball joint which enables it to be used with inclinations in any direction. Movement is transmitted by a motor which operate with constant torque. These combined movements enable the tool to control the real axis of the valve guide and enable the boring is carried out with absolute precision.
