Milling Centre machines very tough
materials
A horizontal/vertical 5-axis milling centre for high-power machining of titanium, SS and alloyed steels, has high torque at the spindle and very high-volume metal removal rates.
Alert in meeting requirements from the most technologically advanced markets and re-confirming the tradition of innovation that distinguishes its entire range of products, Jobs introduces Tarkus: the new horizontal/vertical milling centre for high-power machining with high torque at the spindle, characterised by very high-volume chip removal capability The machine has been specifically conceived to perform the 5-axis high-power and high-torque machining operations of components in very tough materials: such as titanium, stainless and special steel and alloy steel

Moving table milling centre has high power
Large moving-table, fixed gantry, milling centre for high-power machining features high torque at the spindle - 75kW and over 2500Nm - for high metal removal rates.
High speed miller has linear motor drives
A linear motor milling machine for high-speed and high-power machining is a medium- size 5-axis type with mobile crossbeam for finishing and roughing.
Tarkus presents an exclusive architecture with fixed gantry in X-axis and mobile gantry in Z-axis with a medium-large working envelope and can be easily customized to meet end users' specific needs.
Tarkus was studied down to the smallest detail to enable Jobs customers to exploit both high power and spindle torque (37kW and 1300Nm in continuous) and high performance dynamics: the leading edge for this machine class.
The whole machine structure is made of steel weldment, in order to reduce moving masses and consequently improve machine dynamic performances.

Acu-Rite (GB) has announced an extension to its trade-in offer for used DROs until the end of June, so successful has the promotion been.
Z-axis movement is assured by a vertically moving crossbeam: this choice was made to grant an extremely high and almost constant rigidity all along Z stroke (1000mm).
The particular architecture of Y-axis saddle allows to reach the part to be machined in depth without risking collision with the crossbeam.
Specific attention has been paid to the design of machine columns, resulting in a clearance of 2050mm, which allows to work large-sized parts within a restricted overall width of only 3450mm.
The machine can be equipped with a continuous 5-axis milling head available in two different versions: mechanically driven with hydraulic clamping and rotation speed up to 4000 or 6000 rev/min or with interchangeable electric spindle motors up to 24000 rev/min.
The peculiar fork shape of the head combined with the spindle axis off-set positioning allow to increase the operating volume by an extra 500mm with respects to the X- and Y-axis strokes (i e, 3300 + 500mm, 2100 + 500mm).
The A (-15 deg/+120 deg) and C (endless) axes are equipped with a top-rate hydraulic break system assuring the necessary clamping torque (10000 Nm), to carry out the most demanding 3-axis operations.
The table offering remarkable dimensional (3000x1500mm) and loading capabilities assures the highest ergonomics.
The machine configuration with double table enables two pieces to be worked by pendular machining.
Other noteworthy solutions include synchronized operation and work piece change in masked time.
The result is an innovative, high-performance milling centre whose main features include: high-volume removal capability; structural rigidity and high damping capability of vibrations; high dynamics in terms of acceleration and speed; axis strokes: X=3000mm/Y=2100mm /Z=1000mm; constant precision on the whole operating volume; 5-axis mechanically driven milling head (37kW, 1300Nm, 4000 or 6000 Rrev/min), or, as an alternative, with interchangeable electric spindle motors up to 24000 rev/min; high configurability and compactness; production automation; machine full enclosure and reduced foundation requirements.
