Introduction
Parameters
TK2125A CNC HIGH EFFICIENCY DEEPHOLE HONING MACHINE is used for making deephole parts, feeding mechanism adopts double-slant rack with properties of high rigidity and wide machining range. It’s main function includes drilling, boring(can boring blind holes)and rolling. After rolling the roughness usually can reach Ra0.4. It adopts BTA method for drilling, and push-boring method for boring, the coolant is supplied by oil carriage. The clamping of workpiece by oil carriage is controlled by hydraulic system with properties of safety and easy operation. The machine is suitable for both large and small batch of processing of hydraulic cylinders, spindle holes, cylinder holes and coolant holes.
