Vertical Jig Boring-Milling Machine

Methods Machine Tools, Inc. offers the Yasda YBM 640V3 3-axis CNC vertical jig borer designed to provide high speed, precision boring and milling operations for mold, die and complex component manufacturing. "The 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," said a company spokesperson. "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, Inc. "An innovative design fully optimizes the rigidity, repeatability and thermal stability of the Yasda YBM 640V3 for enhanced accuracy, precision and throughput."

"To minimize vibration during acceleration and deceleration, a reinforcement rib under the bridge provides rigidity," said the spokesperson. "Machining efficiency is optimized by keeping the weight of the spindle head and saddle as low as possible. Hand scraped alignment of through-hardened 60 RC boxed ways provides enhanced mechanical accuracy. Spindle bearing preload self-adjusting technology provides improved preload at the full range of spindle speeds. The 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. Included are 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" (700 mm) x 17.7" (450 mm) with a table loading capacity of 661 lbs. (300 kg). X-axis travel is 23.6" (600 mm), Y-axis travel is 15.7" (400 mm) and Z-axis travel is 13.8" (350 mm). 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" (1,800 mm) x 47" (1,200 mm) x 23.6" 600 mm.

Methods represents Yasda across the U.S. and provides local application, sales and support to Yasda customers. Yasda Precision Tools was established in 1929 in Okayama, Japan.
