Super Rigidity Vertical Machining Centers

YAMA SEIKI in house made gear box spindle provides the best torque combination. Box way on 3 axes to fulfill reliable and stable heavy-duty cutting requirement. Precise hand scraping on key contact surfaces to ensure the best support and consistent machine accuracy.

With the advanced R&D technology and strict quality control, BM series is specially made for heavy cutting machining needs, which have rigid and stable machine structure for extensive application. BM series offers excellent performance with reasonable and affordable price.

  • Depends on the different machining requirement, we provides various modular spindle combinations to achieve optimal cutting performance.
  • 3 axes are equipped with box ways which is precisely grinded and thoroughly heat treated, especially suitable for heavy cutting.
  • Highly efficient 24T arm type magazine design provides fast and reliable tool change system.
  • The wide range BM series, X travel start from 850 mm to 2,500 mm ; Y / Z travel start from 600 mm to 1,000 mm to meet your various machining requirements.

Maximum Strength Design

  • The Finite Element Analysis ( FEA ) provides optimal machine design and light-weight structure advantage while ensuring super rigidity of machine.
  • △ ( Delta ) Wide span column construction provides superior cutting stability. The head-stock retains stable even under high speed movement.
  • Based on BESSEL POINTS concept, provides the stable support on Y-axis saddle to keep in minimum deformation, thus to enhance the table dynamic accuracy.
  • Copper piping auto lubrication system delivers metered amounts of lubrication to the slide ways, ball screws, and vital components with ensured reliability.
  • Working table with double ribbed design to enhance the structure strength, while securing the table will not deform even load heavily for a long time.

High Performance Spindle System

  • Gear spindle combines with High-Low 2 steps gear box design to provide large torque output.
  • High hardness Nickel-molybdenum-chromium alloy gear mechanism with auto lubrication and cooling system ensures the performance and lifetime of gear transmission box.
  • High speed spindle and affordable belt type spindle options, which can be adapted with different kinds of spindle motor to fulfill variety of requirement.
  • Spindle, spindle motor, and gear box all pass through the completely running test ensures the performance and lifetime.
