Miyano bna 42 cy/sy machining center 1

Miyano bna 42 cy/sy cnc machining center 

Two BNA seríes models wíth ímproved basic functíons.
Type SY with improved pertormance as a bar-material processing machine.
Type CY may aiso be used as a chucker machíne.
Advantages
Program storage capacity addition.
High-rigidity spindle.
SY: Front and back machiníng.
SY: Equipped with a 12 station turret and one Y-axis.
SY: Short-term increase ín rated power of the maín spíndle.

Standard
1 CY — Gantry loader: Foot mounts for the gantry loader are provided as standard.
Aп automatic shutter that secures space for the loader hand to enter the machine
(above the spíndle) has been adopted. lnstallation of gantry loaders manufactured
by third parties is now supported
2 SY — Foot mounts for the gantry loader

Further (SY only):
• spíndle synchronizing control function
Rigid tapping function superimposition control

Options
1 The chip conveyor allows for rear discharge in addition to the current side discharge. This increases the options for the installation method used.
2 Automatic shutter (SY)
3 Gantry loader
4 Barfeeder

Kínematícs
1 SY: The newly designed base increases the weight of the unit while also improving rigidity. Rectangular lapped slides have been adapted for all slides. The sliding contact between surfaces provídes excellent rigidity and damping performance, as well as strong
cutting performance, while also helping to extend the service life of cutting tools. Additionally, the Z-stroke travel distance has been increased to 50 mm to expand the range of machining available.
2 CY: The newly designed base increases the weight of the unit while also improuing rigidity. Combíníng with a tailstock (option). enables use of long workpieces.
Mounting eyes for the legs of the gantry loader are provided on the left and right side faces of the bed.
You can select whether the chip conveyor discharges to the right or the rear.

Short-term increase in rated power of the front spindle
Power is increased up to 11 kW during spindle acceleration and deceleration to help reduce the cycle tíme

Workíng area
1 Simultaneous machining using both left and right-side spindles enables the turret tool post and front spindle to perform machining while the back spindle follows after to perform superimposed and similar types of machining, thereby further reducing the processing time.

2 A surface plate structure, a tradition of the Miyano brand, has been carried over for the bed, an essential eIement for machining, while both size and weight have been increased in order to improve damping performance. Additionally, the coolant tank capacity has
beeп increased to improve thermal stability. Rigidity of the entire turret tool post has been increased, and equipping with a Y axis enables the use of 12 stations. The number of installed tools has also been increased.

3 The cover has been completely redesigned to improve workability.
The opening has been enlarged for easier access and provided with a large window to improve visibility. The port through which chips fall has been enIarged and the removal port has been moved closer to the outer edge of the cover to make it easier to clean away chips.
These new NC units are standard-equipped with a dual-check safety function to improve safety and productivity.

4 The SY type has a duaI-spindIe/singIe turret tool post mechanical configuration, and the base and turret rigidity has been increased to improve basic functions. The turret tool post has been equipped with a Y axis to expand the number of installed tools to 12 stations
in order to provide the use of a rich assortment of tools, as well as simuItaneous left/right machining for superimposed machining and similar processes. The tool holder and rotary tools are the same used for the current BNA Series and the program compatibility is
also ensured.

5 The CY type was developed under the concept of "Baг and Chucker".
The simple structure of one spindle for one turret tool post can not only perform bar material machining, but you can also combine options such as power chucks or a chip conveyor with rear discharge together with supply/discharge units, such as a gantry loader
manufactured by another company, in order to incorporate the CY type into a production line as a chucker machine.
