You Ji AH09

Q: How much does the You Ji AH09 cost?

The price estimate for the You Ji AH09 is uncertain: we have no price for it that we can cite and no estimate we can stand behind, so we give no figure. Configuration, tooling, automation and installation move the final price substantially. A specific price can be requested at https://machinetoolindex.com/machines/you-ji-ah09#price; the request is passed to You Ji or an authorised dealer.

Price estimate

Uncertain

We do not have a price for the You Ji AH09 that we can stand behind, so we show no number. Configuration, options and installation move the final price a long way: a quote is the reliable figure.

Overview

Pipe couplings, drill collars and long hollow shafts are the reason the You Ji AH09 exists. Its spindle passes Ø232 mm (9.1 in) with a manual chuck arrangement or Ø205 mm (8.1 in) with a hydraulic one, on a heavy-duty horizontal turning lathe with Ø950 mm (37.4 in) of swing.

Note the two bar capacity figures. A hydraulic chuck needs a draw tube inside the spindle, and that tube is what narrows the bore to Ø205 mm (8.1 in). If the stock is closer to the full Ø232 mm (9.1 in), the machine has to be ordered for manual chucking. The catalogue prints the chuck itself as an option for this size, so chuck type and diameter are decided at order.

Speed is traded for bore. The 3-step gearbox runs 1-140, 140-320 and 320-600 rpm from a 37/45 kW (49.6/60.3 hp) motor, on an A2-15 nose. Compare the AH06, which has the same motor and nose but reaches 1,200 rpm with a Ø153 mm (6.0 in) bore.

Beds are listed for 1,000, 2,100 and 3,200 mm (39.4, 82.7 and 126.0 in) of turning length. Standard models carry a 12-station turret and turn Ø900 mm (35.4 in). M models carry a 12-station BMT75 turret and turn Ø800 mm (31.5 in).

Floor planning should include the stock that hangs out behind the headstock. The machine is 5,925, 7,025 or 8,125 mm (233.3, 276.6 or 319.9 in) long by 2,395 mm (94.3 in) wide before any rear support is added.

Strengths & Limitations

Strengths

Ø232 mm (9.1 in) through the spindle with manual chucking, Ø205 mm (8.1 in) with hydraulic
37/45 kW (49.6/60.3 hp) and a low step of 1-140 rpm for large-diameter threading and roughing
Ø950 mm (37.4 in) swing over a Ø900 mm (35.4 in) turning diameter
M models add a 12-station BMT75 turret for milled features on tubular parts

Limitations

Maximum spindle speed is 600 rpm, half that of the AH06
The chuck is printed as an option, so the table gives no chuck size for this model
Hydraulic chucking reduces the usable bore to Ø205 mm (8.1 in)
No bed longer than 3,200 mm (126.0 in) of turning length is listed

Best For

Oil-country tubulars and couplings that pass a Ø232 mm (9.1 in) bore Hollow shafts and hydraulic cylinder tubes up to 3,200 mm (126.0 in) Large flanges up to Ø900 mm (35.4 in) at low rpm

Frequently Asked Questions

01 What is the spindle bore of the AH09?

The table lists bar capacity as Ø232 mm (9.1 in) manual and Ø205 mm (8.1 in) hydraulic. The spindle nose is A2-15, the same nose as the AH06, whose bar capacity is Ø153 mm (6.0 in).

02 How fast does the AH09 spindle turn?

Up to 600 rpm. The 3-step gearbox gives 1-140 rpm, 140-320 rpm and 320-600 rpm, driven by a 37/45 kW (49.6/60.3 hp) spindle motor. That is enough surface speed on large diameters but slow for small ones.

03 Does the AH09 come with a chuck?

The catalogue prints the chuck size as "Option" for the AH09, where the AH06 lists a Ø690 mm (27.2 in) hydraulic chuck. Expect to specify the chuck, and whether it is manual or hydraulic, with the order, because that choice also sets the bar capacity.

04 Which bed lengths and turrets are offered?

Maximum turning length is 1,000, 2,100 or 3,200 mm (39.4, 82.7 or 126.0 in). Each length is listed with a 12-station turret at Ø900 mm (35.4 in) turning diameter, and as an M model with a 12-station BMT75 turret at Ø800 mm (31.5 in).
