#theunstoppable: planer-type boring and milling center with customized vertical table

#theunstoppable brings you this time our last planer type boring-milling center JUARISTI TX3-S, delivered last week to the Russian manufacturer IZ-Kartex

Customized planer type boring-milling center

This week in #theunstoppable we introduce you one of the most special customized projects of this year. It is a comprehensive boring and milling center of the TX-S series, accompanied, on this occasion, by a truly exclusive complement: a large vertical rotary table adapted by the JUARISTI Group to the particular needs of the client.

The machine has been designed taking into account the production needs of IZ-Kartex, Russia’s largest manufacturer of components for electromechanical shovels and rotary drilling rigs.

Truly exclusive TX3-S boring center

The machine manufactured for IZ-Kartex is a TX3-S model (JUARISTI’s best known series), a planer-type boring and milling center with thermo-symmetrical design and column-centered spindle assembly.

Its wide working courses ensure efficient machining of large components (X=3,000 mm; Y=3,000 mm; Z=3,000 mm; W=800 mm). In addition, it offers high roughing capacity and high machining power:

• Main spindle diameter…….…………………………………………………………….…..……..130 mm
• Speed rotation…….………………………………………….…………………..…….………4.000 min-1
• Spindle drive power continuous………………………………………………….………………….46 kW
• Main spindle torque………………………………………………….………………………….2.008 Nm

The jewel in the crown: a large vertical table of high precision

What makes this project so special is the large vertical table it comes with, adapted to IZ-Kartex’s production needs. This vertical rotary table has been designed to be used as indexing plate and controlled axis for machining large parts, with a maximum tipping diameter of 2.500 mm and maximum rotation speed of 2,5 rpm. We have ensured in our Accuracy Cube that the table perfectly fulfills all the precision requirements demanded by the client.

Upmost accuracy and precision

It is motorised with a twin-drive double servomotor system for positioning with no mechanical looseness and an additional ROD880C encoder for direct position reading on the axis of the plate.

The rotary drive operation is performed with two servomotors in “master-slave” or “twin drive” mode. In this case, two gearboxes prepared for two servomotors have been mounted.

Comprehensive automation package

In addition to the vertical divider, the IZ-Kartex machine includes a 2,500 x 3,000 mm table compatible with workpieces up to 40 t capacity. It also has an attachment changer with store for 2 attachments to switch between the boring bar and the automatic milling head (ACD1) included in the project. Finally, it comes with an automatic tool changer of up to 40 positions and compatible with tools up to Ø250 x 600 mm.
