How much does the Juaristi TX-RAM cost?
Price estimate
We do not have a price for the Juaristi TX-RAM 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 Juaristi TX-RAM is a table-type milling-boring center with a RAM: the head sits centred in the column, and a four-side guided RAM centred in the headstock adds a V axis of 800-1,000 mm (31.5-39.4 in) between the column and the boring bar. Juaristi calls the arrangement box-in-box.
One column of the table covers the whole range, so most rows are lists. X is 2,000, 3,000, 4,000, 5,000 or 6,000 mm. Y has six steps from 1,500 mm to 4,000 mm, Z four from 1,500 mm to 3,000 mm. Boring bars are 130-150-180 mm, table loads 20,000-40,000-60,000 kg, and table sizes run from 1,600×1,600 mm up to 3,000×4,000 mm. The table does not show which travels, bar and load go together, which means a TX-RAM is defined by its quotation more than by this page.
The reason to choose it over a boring mill without a RAM is reach with stiffness. A boring bar alone goes into a part as a slender tool; a RAM carries the full headstock section toward the work, so milling heads and short, stiff tools can be used deep inside a large fabrication. Juaristi lists a universal head, an orthogonal head and a compact ISO 50 vertical head with an automatic head changer for that purpose.
Head spindle power is 46/64 kW, with speeds of 3,500-3,000-2,500 min-1, presumably one per bar diameter. Table rotation is 5-3 min-1 and rapid feeds 30-25-20 m/min. The maker also speaks of turning parts up to 5,000 mm long and weighing 60 t on the work area, though no turning speed is given in the table.

Strengths & Limitations
Strengths
- RAM with 800-1,000 mm of V travel, guided on four sides in a box-in-box headstock
- Travels up to 6,000 mm in X, 4,000 mm in Y and 3,000 mm in Z
- Table loads of 20,000-40,000-60,000 kg on tables up to 3,000×4,000 mm
- Boring bar diameters of 130-150-180 mm with up to 64 kW
- Central maintenance cabinet for hydraulic, lubrication and pneumatic units
Limitations
- One table column covers every size, so travel, bar, load and speed combinations are not defined on the page
- No W travel for the boring bar is printed, although the rapid feed row is headed X, Y, Z, W
- No spindle torque figure is published in the table
- Table rotation is as low as 3 min-1 and rapid feeds as low as 20 m/min in the listed ranges

Frequently Asked Questions
01
A V axis of 800-1,000 mm (31.5-39.4 in). The RAM is centred in the headstock and guided on four sides, which Juaristi describes as a box-in-box concept. It lets the head move toward the part, so milling heads can work at depth and the boring bar starts closer to the bore.
02
X is 2,000, 3,000, 4,000, 5,000 or 6,000 mm. Y runs 1,500-2,000-2,500-3,000-3,500-4,000 mm and Z 1,500-2,000-2,500-3,000 mm. Table sizes go from 1,600×1,600 mm up to 3,000×4,000 mm with load capacities of 20,000-40,000-60,000 kg.
03
Head spindle power is 46/64 kW (61.7/85.8 hp). Spindle rotation speed is listed as 3,500-3,000-2,500 min-1 and boring bar diameter as 130-150-180 mm. The three speeds line up in number with the three bar sizes, but the table does not state the pairing or any torque.
04
The TX-S series feeds a boring bar on a W axis from a head without a RAM. The TX-RAM puts a RAM with a V axis between column and bar. In Juaristi's tables the TX-RAM also spans its size range in one column, with loads from 20,000 kg to 60,000 kg, where the TX-S series is split into separate sizes.
