02 Miyano BNX-51MSY

This machine, developed based on the best-selling BNJ series under the Miyano brand, has inherited the characteristics of the Miyano brand in terms of the highly rigid basic con� guration and hand scraped slideways, and demonstrates stable machining accuracy.

In addition to that, even larger and longer workpieces can be handled thanks to the extended stroke of the X1 axis, increased capacity of the servomotor, extended stroke of the X2 axis, and increased back spindle chuck size.

By adopting a Mitsubishi control, highly ef� cient machining is achieved through a wealth of machining support functions and superimposition machining, which is the biggest feature, in combination with the excellent operability cultivated under the Cincom brand.

Basic Construction

Large Opening for Easy SetupHigh-rigidity Y Axis

The highly rigid bed modeled on a “platform construction” is able to maintain a stable � at surface over long periods, has excellent heat dissipation characteristics due to ribs in a grid pattern, and minimizes distortion of unit mounting faces resulting from effects of heat.

In addition, “hand scraped slideways,” rigid and with excellent damping characteristics, are featured on all axes. In combination with the highly rigid base, they support stable machining accuracy.

The generous door opening improves access to the machining area, lightening the load on the operator.

The 12-station turret, allowing revolving tools to be mounted at all stations, incorporates a Y axis and supports the machining of complex shapes.

Display of easily under-stood illustrationsAll you have to do is input the machining length, chuck-ing length and so on, and the escape and approach positions are automatically calculated.

On-machine program check functionUsing manual handle feed, operations can be run in the forward or reverse direc-tions, and you can temporar-ily stop program operation, edit the program, and then restart operation.

Display of code listThe function displays the list of G and M codes including explanations of the arguments to support programming.

Simultaneous Machining Possibilities“Superimposition control” where machining is performed with the movement of the back spindle synchronized with that of the tool slide, can be said to be the biggest feature of this machine.

Spindles with a thick-walled construction and large-diameter bear-ings minimize de�ection and enable continuously stable operation. Assembling and inspecting these spindles based on a strict man-agement system gives them ample rigidity, abnormal heat output suppression, and manageable thermal displacement characteristics, allowing high-precision machining.

By using an angular contact ball + double-row roller format for the front bearings and double-row roller bearings for the rear bearings, the spindle of the BNX51 achieves stable, high-accurate rotation and withstands loads in the radial direction extremely well.

The use of 25 Nm revolving tools on the 12-station tool slide 1 accomplishes rigid and stable milling.
