Methods Machine Tools Inc. has announced the introduction of the new Yasda YBM 640V3 3-Axis CNC vertical jig borer, which provides high-speed, precision boring and milling operations for high accuracy mold, die and complex component manufacturing. The new YBM 640V3 simplifies moldmaking in industries such as aerospace, automotive, medical, defense and more, as well as the production of electronic, optical and other extremely complex components, according to the company. The accuracy and rigidity of the YBM 640V3 jig borer virtually eliminates the need for hand polishing.

"Yasda jig borers consistently achieve outstanding performance in heavy duty machining, something conventional jig borers have traditionally not been known for," said David Lucius, Vice President of Sales for Methods Machine Tools. "A very innovative, unique design fully optimizes the rigidity, repeatability and thermal stability of the Yasda YBM 640V3 for the utmost in accuracy, precision and throughput."

To minimize vibration during acceleration and deceleration, a reinforcement rib under the bridge provides great rigidity. Machining efficiency is optimized by keeping the weight of the spindle head and saddle as low as possible. Meticulous hand scraped alignment of through-hardened 60 RC boxed ways provides outstanding mechanical accuracy. An exclusive spindle bearing preload self-adjusting technology provides optimum preload at the full range of spindle speeds. A rugged spindle enables a full range of machining from heavy duty roughing to delicate fine finishing, all while providing a long tool and spindle bearing life.

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 pre-tension. Productivity is further increased by improved chip disposal and large coolant and lubrication tank capacities.

The 3-Axis Yasda YBM 640V3 has a standard spindle speed of up to 24,000 RPM (30,000 RPM optional) and a 7/24 taper, No. 40 spindle taper hole. The table size is 27.5 inches (700mm) x 17.7 inches (450mm) with a table loading capacity of 661 lbs (300 kg). X-axis travel is 23.6 inches (600mm), Y-Axis travel is 15.7 inches (400mm) and Z-Axis travel is13.8 inches (350mm). The automatic tool changer has a maximum storage of up to 100 tools. The YBM 640V3 is equipped with a FANUC 31i-Model 5 controller. The Yasda YBM 640V3 is the smallest of a complete vertical line-up of Yasda CNC Jig Borers with the largest 1218V model reaching travels of 71 inches (1,800mm) x 47 inches (1,200mm) x 23.6 inches 600mm.
