Miyano bnj 42 S 42/51 SY cnc lathe

Economical, efficient and powerful thanks to simultaneous machining.
Turret No. 2 now has 8 tool mounting stations instead of 6 on the previous
machines, so the number of tools has been increased and also rotary tools may
be mounted. The milling processes that were handled using turret No. 1 alone can
now be shared with turret No. 2, making it possible so substantially shorten cycle
times and deal with workpieces that require complex machining.
Advantages
Considerably improved operability.
Collision protection rapid feed only .
Machining time shortened by simultaneous machining at left and ríght.
Combined Machining with the Y-axis.
Machining time shortened through superimposition machíning.
Optional tor 64 mm available.
Workpíece example
Name Adjusting screw
Material Brass standard

Workíng area
1 Turret No.1 accommodating hígher-torque revolving tools
Since a singie drive mechanism is used to drive the revolvíng 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 accommodatíng revolvíng tools and with a bigger tool capacíty
The number of tool mounting positions has increased from the síx on existing machínes to eight. The turret also now accepts double plain holders, greatly increasing the number of tools that can be mounted.

2 Collіsion bufferíng (just rapid traverse operatíon)
When interference is encountered in rapid traverse operation, the function decelerates and
stops axis feed and generates retraction torque to retract the feed axis іn the opposite direction to the collísíon dírection,límíting damage to the machine.
