Makino milling cutter exhibits machining center for high precision machining of die plates

Makino Milling Tool Co., Ltd. exhibited the vertical machining center (MC) developed by the company at the 24th Japan International Machine Tool Show (JIMTOF2008) (October 30-November 4, 2008, Tokyo Ariake International Convention and Exhibition Center). ) "FB127". It is mainly used for high-Precision Machining of die plates such as punching dies and punching plates. The accuracy is within ±2.5μm and the price is 38 million yen (excluding tax, standard performance indicators).

The improvement of machining accuracy is mainly achieved by perfecting the cooling technology to suppress mechanical deformation. In addition to the vertical MC "V56i", which was also put on the market on October 22, 2008, adding cooling oil to the main shaft and the motor bracket, and designing the feed screw pair (ball screw pair) to be hollow, added In addition to the construction of the cooling oil, the FB127 is also provided with a cooling passage up to the guide. This keeps the guide and the tip section at the same temperature. Therefore, continuous processing can be performed even if it is 100 to 200 rubber mold sheets which require 10 hours or more of processing.
