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 Series is a CNC floor-type horizontal boring and milling machine, and its listed figures put it at the large end of that class: X travel of 10,000 – 30,000+ mm depending on the installation, a 130 mm or 160 mm boring spindle and a 55 – 75 kW (74 – 100 hp) S1 continuous spindle motor.

Power and structure are the two things to look at first. The motor rating depends on configuration, and the spindle covers 2 – 2,500 RPM through a 2-range gearbox, so the low range is there for big cutters and boring bars. The guideways are listed as hand-scraped box ways or hydrostatic, again configuration-dependent. That choice should be settled in the specification, not assumed.

Rapid traverse on the linear axes is listed at 8,000 mm/min. On an X axis that starts at 10,000 mm, moving from one end of the part to the other takes real time, so jobs are best planned to finish one zone before moving on. Y travel is 3,000 – 4,500 mm and Z is 1,500 – 2,500 mm, with a spindle extension (W axis) of 700 – 900 mm.

A facing head (U axis) is listed as included, for large-diameter boring and face milling. The ATC has 60 – 120 positions with a maximum tool weight of 35 kg. Work is held on a floor T-slot plate or on foundation-mounted fixtures, and a CNC rotary table (B axis) is optional. Control is listed as Heidenhain TNC 640 or Siemens 840D sl, and machine weight as 80,000 – 200,000+ kg depending on configuration.

Strengths & Limitations

Strengths

Spindle motor of 55 – 75 kW (74 – 100 hp) S1 continuous, depending on configuration
X travel of 10,000 – 30,000+ mm, set per installation
Facing head (U axis) is listed as included, for large-diameter boring and face milling
Guideways offered as hand-scraped box ways or hydrostatic, depending on configuration
ATC with 60 – 120 positions and a 35 kg maximum tool weight

Limitations

Rapid traverse of 8,000 mm/min on the linear axes makes long repositioning moves slow on an X axis of 10,000 mm or more
The CNC rotary table (B axis) is optional, so multi-face work on the base machine means re-setting the part
Spindle speed tops out at 2,500 RPM, which limits small-diameter tools
Machine weight of 80,000 – 200,000+ kg, depending on configuration, calls for a dedicated foundation

Best For

Very long weldments and castings along 10,000 – 30,000+ mm of X travel Heavy roughing with the 55 – 75 kW (74 – 100 hp) S1 spindle motor Large-diameter boring and face milling with the included facing head Parts too large for a table, set on a floor T-slot plate or foundation-mounted fixtures

Frequently Asked Questions

01 What spindle power is listed for the MX Series?

The spindle motor is listed at 55 – 75 kW (74 – 100 hp) S1 continuous, depending on configuration. It drives a 130 mm or 160 mm boring spindle over 2 – 2,500 RPM through a 2-range gearbox. No torque figure is listed, so ask for the torque curve of the configuration being quoted.

02 How long can the X axis be on the MX Series?

The listed figures give 10,000 – 30,000+ mm, described as installation-specific. Y travel is 3,000 – 4,500 mm depending on configuration and Z is 1,500 – 2,500 mm. The W-axis spindle extension adds 700 – 900 mm.

03 What guideways does the MX Series use?

The table lists hand-scraped box guideways or hydrostatic guideways, depending on configuration. Which one a given machine has is part of its specification, so it should be stated in the quotation along with the rapid traverse, which is listed at 8,000 mm/min for the linear axes.

04 Does the MX Series include a facing head and rotary table?

The facing head (U axis) is listed as included and is intended for large-diameter boring and face milling. The CNC rotary table (B axis) is listed as optional. Without it, the workpiece sits on a floor T-slot plate or foundation-mounted fixtures.

05 What are the tool changer limits on the MX Series?

The ATC is listed with 60 – 120 positions and a maximum tool weight of 35 kg. No maximum tool length or diameter is listed, so large boring bars and facing tools should be checked against the changer of the configuration on offer.
