BNJ 42/51SY6


Featuring 2 spindles and 2 turrets, the main turret with Y axis function the BNJ-42SY6 / 51SY6 allows simultaneous and complex machining.

  • Processing overlap control with main spindle processing combined with separate sub-spindle movement
  • Eccentric collet enables complex machining of cranks and other eccentric processing
  • It makes easy side milling through the Y-axis function of main turret, thus enables machining of large-diameter screws and/or uneven parts that was impossible to conduct by conventional machines

Turret No. 1 Accommodating Higher-torque Revolving Tools

Since a single drive mechanism is used to drive the revolving tools, they can be mounted at all stations. With a maximum torque of 25 Nm, they can handle heavy-duty cutting too.

Turret No. 2 Accommodating Revolving Tools(option) and with a Bigger Tool Capacity

The number of tool mounting positions has increased from the six on existing machines to eight. The turret also now accepts double plain holders, greatly increasing the number of tools that can be mounted.

Machining Time Shortened by Simultaneous Machining at Left and Right

High efficiency is assured by having turret No. 1 and 2 machine simultaneously at left and right at spindles 1 and 2.
