Makino car engine special machining center, high precision and convenience

At the recent 25th Japan International Machine Tool Show (JIMTOF2010), Makino Milling Tool exhibited the 'BH50' machining center for automobile engines. It is understood that compared with ordinary machining centers, BH50 has higher precision and efficiency, and the process is simple, saving time and manpower for secondary processing. First of all, BH50 ensures good air tightness of the combustion chamber, which is mainly due to the one-time machining of the joint surface of the cylinder block and the rod head by its large-diameter face milling cutter. The whole process is simpler and faster; The moment spindle and high mechanical rigidity BH50 realizes the rough machining of cylinder holes based on multi-blade large diameter boring machining; thirdly, thanks to the Z-axis travel of up to 780mm, the BH50 can perform linear boring machining of crankshaft holes and cam holes ;Finally, the inclined machining of the joint surface of the cylinder block and the cylinder head is completed by cutting the B-axis index table (rotary table) to achieve the finishing of the valve plate and the valve guide. It is said that Makino milling cutters have been on sale since October 15, 2010.
