Methods Machine Tools Inc. has announced the introduction of the new Yasda YBM 640V3, a 3-axis CNC vertical jig borer. It provides high-speed, precision boring and milling operations for high-accuracy mold, die, and complex component manufacturing.
The unit is designed for moldmaking for such industries as aerospace, automotive, medical, and defense, as well as the production of electronic and optical components. The jig borer nearly eliminates the need for hand polishing.
A reinforcement rib under the bridge helps minimize vibration during acceleration and deceleration. The spindle head and saddle weights are kept as low as possible to help optimize machining efficiency. The spindle can handle machining jobs from heavy-duty roughing to delicate fine finishing.
To reduce thermal distortion, a bridge cooling system is located under the X-axis guide, and a jacket cooling system for X- and Y-axis ball nuts prevents loss of ball screw pretension.
