How much does the Koike Aronson VersaGraph Extreme cost?

Price estimate

Uncertain

We do not have a price for the Koike Aronson VersaGraph Extreme 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

The Koike Aronson VersaGraph Extreme is the widest and heaviest gantry in the maker's plasma and oxy-fuel range. Six models are listed, from the 2500 with 96 in (2,438 mm) of effective cutting width to the 7500 with 288 in (7,315 mm), twice the width of the largest MasterGraph. Table capacity is 12 in (305 mm) and plasma systems run from 200 to 800 amp.

It is the only Koike gantry here that lists 4 plasma or marker stations and two full-contour plasma bevel heads as an option. Together with up to 10 oxy-fuel stations, 9 slave stations and 10 tools, that suits a plant that cuts several plates or several strips at once across a very wide table. The oxy-fuel gas system is Servo Gas, rated for 10 in (254 mm) of thickness.

Koike publishes motion accuracy for this model: .015 in (0.38 mm) accuracy and .005 in (0.13 mm) repeatability, as compensated machine motion in 72 in measured with a laser interferometer, and the machines are tested to ISO 230-2. Rapid traverse is 1,400 ipm (35.6 m/min) and maximum contour speed 600 ipm (15.2 m/min), from 6 hp (4.5 kW) AC servo drives on the X and Y axes.

The rail is floor mounted, a 37 KG triple machined section that can be extended for more cutting length or for additional machines on a common rail. At 437 in (11,100 mm) of machine width on the 7500, the building bay and crane coverage need checking early. The control is the Hypertherm Edge Connect and the power requirement is 480/3/60 at 30 AMP. The brochure prints an effective cutting length that does not agree with the maker's other gantry tables, so it is left out here; the product page quotes cutting lengths of 10 to 100 ft.

A second column for 2 slave stations runs from 120 in (3,048 mm) to 312 in (7,925 mm).

02 How many torches can the VersaGraph Extreme carry?

The table lists a maximum of 10 tools, 9 slave stations, 10 oxy-fuel stations and 4 plasma or marker stations. Koike's product page also offers two full-contour plasma bevel heads as an option.

03 How accurate is the VersaGraph Extreme?

Koike states machine motion accuracy of .015 in (0.38 mm) and repeatability of .005 in (0.13 mm), as compensated machine motion in 72 in, measured with a laser interferometer. All machines are tested to ISO 230-2 standards.

04 What control, drives and power does it use?

The machine CNC is the Hypertherm Edge Connect. The drive system is 6 hp (4.5 kW) AC servo, and the brochure names 18 Amp Bosch/Rexroth drives. The power requirement is 480/3/60 at 30 AMP, with the plasma systems on their own supply.

05 How does it differ from the MasterGraph EX2?

In width and in station count. The MasterGraph EX2 stops at 144 in (3,658 mm) of effective cutting width with 5 slave stations and lists 2 plasma or marker stations and 8 oxy-fuel stations. The VersaGraph Extreme reaches 288 in (7,315 mm) and lists 4 and 10. Both have 1,400 ipm (35.6 m/min) rapid traverse.
