Machine Information

Miyano BNE-51/65MYY

MYY models equipped with double-Y axis

The BNE-51MYY and BNE-65MYY, with machining diameter of 51mm and 65mm respectively, has inherited the characteristics of high rigidity and precision for which the BNE series has been greatly praised.

The cover has been completely redesigned with a large window to provide excellent visibility. It has also been equipped with a new HMI (Human Machine Interface). Use of a touch panel improves operability and its use with the new NC unit also improves productivity.

Additional Details

MYY models equipped with double-Y axis

The upper and lower turrets of the BNEMYY are equipped with a Y axis. Operating with the same capabilities, these two 12-station turrets provide even more flexible tooling due to optimal process allocation that is not restricted by machining balance limitations.

Reduced Cycle Times with High-Efficiency Machining

The two turrets equipped with a Y axis, and mechanical structure formed from the front and back spindles serve to reduce cycle times by enabling high efficiency machining such as simultaneous left/right and up/down machining for superimposed and similar types of machining.

Maximum machining diameter of 65 mm

The 65mm bar capacity of the BNE65 gives it the largest machining capability of the entire Miyano brand.The output of the front and back spindle motors has been increased 1.2 to 1.5 times that of current models, greatly improving cutting capability. Additionally, increasing the maximum speed to 5,000 rpm enables optimal conditions for cutting of small-diameter workpieces.

New HMI (Human Machine Interface) Operating Panel

A new HMI equipped operating panel with a 15-inch touch panel has been adopted to improve operability for workers. Additionally, universal design has been applied to operating panel colors and similar elements for the first time. Universal design has been adopted in consideration of the different ways colors are perceived to ensure that information is provided in a manner that is readily visible and easily understood by anyone.
