Overview

The Miyano BNA-42CY is a single-spindle turning center with one 12-station turret and a Y axis, sized for 42 mm dia. bar and, in Citizen's words, a CY type that can also be used as a chucker. It takes 5" and 6" hollow chucks as well as collets, and its maximum machining length is 200 mm.

The spindle runs 60 - 6,000 rpm on a motor rated 11/7.5/5.5 kW (15%/15min/cont.): 11 kW at 15% duty, 7.5 kW for 15 minutes and 5.5 kW continuous. The continuous figure is the one to use when planning long roughing passes. Collet choice is wide, with Hardinge S20, DIN173E, B&S#22, JPN34 and HAINBUSH types listed, which helps a shop that already stocks one of those systems.

All 12 turret stations can take rotary tools, running 50 - 5,000 rpm on a 2.8/1.0 kW motor. With a Y axis, those tools can drill and mill off the part centreline. Feed rates are 20 m/min on X and Z and 23 m/min on Y. Turning tools are 20 mm Sq. and the tool post holes 25 mm dia.

There is no second spindle, so the cut-off face of a bar part needs a second operation, and that is the main thing to weigh against the two-spindle machines. In return, the BNA-42CY is a small installation: 16 kVA of power, W2,260×D1,433 mm of floor, 1,745 mm of height and 3,220 kg, against 6,250 kg for the Miyano ANX-42SYY.

Strengths & Limitations

Strengths

Usable as a chucker with 5" and 6" hollow chucks, as well as for 42 mm dia. bar
200 mm maximum machining length
Spindle motor 11/7.5/5.5 kW (15%/15min/cont.) with a 60 - 6,000 rpm range
12-station turret taking up to 12 rotary tools at 50 - 5,000 rpm
Collet types listed: Hardinge S20, DIN173E, B&S#22, JPN34 and HAINBUSH

Limitations

One spindle only: the back of the part needs a second operation
Rotary tools rated 2.8/1.0 kW, enough for drilling and light milling only
Rotary tools top out at 5,000 rpm, below the 6,000 rpm spindle

Best For

Chucked parts in 5" or 6" hollow chucks Bar work up to 42 mm dia. machined from one side Parts up to 200 mm long with off-centre features from the Y axis Shops with a 16 kVA supply and limited floor space

Frequently Asked Questions

01 Can the Miyano BNA-42CY work as a chucker?

Yes. Citizen describes the CY type as usable as a chucker machine, and the table lists 5" and 6" hollow chucks alongside collet chucks for bar work at the 42 mm dia. standard machining diameter.

02 Does the BNA-42CY have a sub-spindle?

No. The table lists one spindle and one tool post, a 12-station turret. Parts that need the cut-off face machined go to a second operation or to a two-spindle machine; for one-sided parts up to 200 mm long the single spindle is enough.

03 What are the motor ratings?

The spindle motor is rated 11/7.5/5.5 kW (15%/15min/cont.): 11 kW at 15% duty, 7.5 kW for 15 minutes and 5.5 kW continuous. The rotary tool motor is rated 2.8/1.0 kW and drives the tools at 50 - 5,000 rpm.

04 What are the axis feed rates on the BNA-42CY?

20 m/min on X and Z and 23 m/min on Y. The Y axis lets the rotary tools drill and mill away from the part centreline, so flats, cross holes and slots can be finished on the machine.

05 What does it need on site?

A 16 kVA supply, a floor area of W2,260×D1,433 mm and 1,745 mm of height; the machine weighs 3,220 kg. Add space for bar loading if it will run from bar rather than as a chucker.
