Harrison Alpha 1760XC

Q: How much does the Harrison Alpha 1760XC cost?

The price estimate for the Harrison Alpha 1760XC 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/colchester-harrison-alpha-1760xc#price; the request is passed to Colchester or an authorised dealer.

Price estimate

Uncertain

We do not have a price for the Harrison Alpha 1760XC 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

With 8 kW (10.7 hp) at the driven tools and 22 kW (29.5 hp) at the main spindle, the Harrison Alpha 1760XC is the heavyweight of the Alpha turn-mill models. Its turret has 12 stations, all driven, on VDI 40 / DIN 5482 tooling. The C-axis works on a spindle with a 155 mm (6.1 in) bore and an A2-11 nose.

Compare those numbers with the mid-size XC and the intent is clear. The Harrison Alpha 1550XC has 3.7 kW (5.0 hp) driven tools and only 4 driven stations out of 8. Here every station can carry a rotating tool and each has more than double the power. Driven-tool speed is lower, at 4,000 rpm, which fits larger cutters.

The machine swings 760 mm (29.9 in) over the bed and 560 mm (22.0 in) over the cross slide, with six bed lengths from 1,500 mm (59.1 in) to 6,000 mm (236.2 in). Spindle speed is 10 - 1,400 rpm. Chucks of 20 / 24 in (508 / 610 mm) are listed. That is a big envelope for a lathe that keeps a manual mode, and it suits parts such as large valve stems, rolls with keyways, flanged shafts and couplings that would otherwise go from a big lathe to a horizontal borer.

Only one spindle configuration is offered, in contrast to the three on the 2-axis Harrison Alpha 1760XS. A hydraulic main spindle holding brake and Cs axis control are standard. Steady rests, hydraulic chucking, hydraulic tailstock and a swarf conveyor are options. Colchester fits the Fanuc 0i-TF Plus with a 10.4 in colour touch screen.

Strengths & Limitations

Strengths

12-station turret with all stations driven, on VDI 40 / DIN 5482 tooling
Driven tools rated 8 kW (10.7 hp) at up to 4,000 rpm
22 kW (29.5 hp) main spindle, the most powerful in the Alpha range
155 mm (6.1 in) spindle bore on an A2-11 nose
Bed lengths up to 6,000 mm (236.2 in) between centres

Limitations

Main spindle speed range is 10 - 1,400 rpm, so small-diameter work is slow
One spindle configuration only; the 230 mm (9.1 in) bore of the Harrison Alpha 1760XS is not listed here
No Y-axis is listed for off-centre milling
Steady rests and hydraulic tailstock are options that long work will require

Best For

Large shafts and rolls with milled keyways or drilled patterns, up to 6,000 mm (236.2 in) Heavy flanged parts on 20 / 24 in (508 / 610 mm) chucks Milling on the lathe that needs 8 kW (10.7 hp) at the tool Replacing a lathe-then-borer route on low-volume heavy parts

Frequently Asked Questions

01 What are the driven tool specifications of the Harrison Alpha 1760XC?

Driven tool spindle power is 8 kW (10.7 hp) and maximum driven tool speed 4,000 rpm. The turret has 12 stations, all driven, and the tooling type is VDI 40 / DIN 5482. Cs axis control and a hydraulic main spindle holding brake are standard features.

02 How big is the machine's working envelope?

Swing over the bed is 760 mm (29.9 in), swing in the gap 1,040 mm (40.9 in) and swing over the cross slide 560 mm (22.0 in). Distance between centres is 1,500 / 2,000 / 3,000 / 4,000 / 5,000 / 6,000 mm (59.1 / 78.7 / 118.1 / 157.5 / 196.9 / 236.2 in).

03 What is the main spindle rated at?

22 kW (29.5 hp), with a speed range of 10 - 1,400 rpm, an A2-11 nose and a 155 mm (6.1 in) bore. Chuck size is listed as 20 / 24 in (508 / 610 mm). The 2-axis Harrison Alpha 1760XS is rated 18.5 kW (24.8 hp).

04 Does it keep the Alpha manual mode?

Yes. Colchester describes five operating modes for both XS and XC machines: Manual Mode, the Alpha System conversational mode, Manual Guide i, AlphaLink offline programming and Full CNC Mode. The control is the Fanuc 0i-TF Plus touchscreen.
