STH 450

STH 450 Automatic Hydraulic Honing Machine: Is designed for honing the engine block linings and similar cylinder at the requested precision and specifications. The work-head body and its slides are made of high quality cast-iron resistant to vibration. All functions of the machine can be achieved from one control panel which is fixed to the body with a hook in order to provide a usage from various angles and digital indicators, pressure gauge, digital rotation adjustment, hydraulic moving precision adjustment can be done from this control panel. The lower table which can be moved freely facilitates the centering or the engine block and minimizes the time wasted on this process. The adjusment of the turn rotation and moving speed of the honing head independently from each other and non-conditioned provides the spiral angles formed on the bored surface to get the requested value. Moreover, the honing head’s having the magnetic braking system at any place and rotation avoids the damage of the spiral angles.
