Our best estimate for a cnc boring machine in this class — not a quote from Juaristi. Configuration moves it a long way.

Overview

The Juaristi MX is a boring mill that works over a floor plate or a CNC rotary table, listed with a 150 mm (5.9 in) spindle, 2,500 mm (98.4 in) of Y travel and 2,000 mm (78.7 in) of Z travel. Only X is open: the listed figures give 4,000 - 10,000+ mm (157.5 - 393.7+ in), configurable.

With Y and Z fixed, sizing an MX comes down to part length. The vertical and cross travels do not grow with the X axis, so a part taller than 2,500 mm (98.4 in) is outside this machine however long the bed. Reach into the part comes from the spindle's W travel of 1,000 mm (39.4 in), enough to bore well inside deep housings without extended tooling.

The spindle is listed at 45 - 60 kW (60 - 80 hp) with a 2,500 rpm maximum, and the taper is ISO 50 / Capto C8. The taper matters for the tooling a shop already owns, so it should be fixed early. The magazine holds 60 - 100 tools. An optional rotary table is listed at up to 4,000 mm (157.5 in) in diameter for parts that need indexing.

The listed figures also state accuracy: positioning of 0.008 mm (0.0003 in) and repeatability of 0.005 mm (0.0002 in). Control is Heidenhain TNC 640 or Siemens 840D SL. Machine weight is listed at 50,000 - 80,000 kg (110,231 - 176,370 lb) depending on configuration, which sets the foundation requirement.

Strengths & Limitations

Strengths

W-axis spindle travel of 1,000 mm (39.4 in) on a 150 mm (5.9 in) spindle for deep boring
Listed positioning accuracy of 0.008 mm (0.0003 in) and repeatability of 0.005 mm (0.0002 in)
Spindle taper listed as ISO 50 / Capto C8, with 45 - 60 kW (60 - 80 hp) of spindle power
X travel is configurable, listed as 4,000 - 10,000+ mm (157.5 - 393.7+ in)
Optional rotary table up to 4,000 mm (157.5 in) in diameter

Limitations

Y travel is fixed at 2,500 mm (98.4 in) and Z at 2,000 mm (78.7 in), whatever X length is chosen
The rotary table is optional; the alternative listed is a floor plate, where the part cannot be indexed
Maximum spindle speed of 2,500 rpm limits small-diameter tooling
No rapid traverse or feed figures are listed, so cycle-time estimates need data from the quotation

Best For

Long parts no taller than the 2,500 mm (98.4 in) Y travel Deep bores reached with 1,000 mm (39.4 in) of W-axis spindle travel Large round or multi-face parts on the optional rotary table up to 4,000 mm (157.5 in) Shops standardised on ISO 50 or Capto C8 tooling

Frequently Asked Questions

01 What are the travels of the Juaristi MX?

X is configurable and listed as 4,000 - 10,000+ mm (157.5 - 393.7+ in). Y is 2,500 mm (98.4 in), Z is 2,000 mm (78.7 in) and the spindle's W travel is 1,000 mm (39.4 in). Only X changes with the configuration.

02 How accurate is the Juaristi MX?

The listed figures give a positioning accuracy of 0.008 mm (0.0003 in) and a repeatability of 0.005 mm (0.0002 in). The table does not say over what length or to which standard these are measured, so the acceptance conditions should be agreed in the purchase specification.

03 What spindle and taper does the MX have?

A 150 mm (5.9 in) spindle rated 45 - 60 kW (60 - 80 hp) with a maximum of 2,500 rpm. The taper is listed as ISO 50 / Capto C8. No torque figure is listed.

04 Is a rotary table included with the MX?

The table type is listed as floor plate or CNC rotary table, and the rotary table itself as optional, up to 4,000 mm (157.5 in) in diameter. A machine specified with only the floor plate cannot index the part, so multi-face work needs a second setup.

05 How many tools does the MX magazine hold, and how heavy is the machine?

The tool magazine capacity is listed as 60 - 100 tools. Machine weight is 50,000 - 80,000 kg (110,231 - 176,370 lb) depending on configuration, so the foundation has to be designed for the X length chosen.
