The ultimate fusion of turn-mill operations
Vertical machining center Horizontal machining centerNC lathe
A divided production line
Turning, V/H machining center, material handling operationsconsolidated into 1 machine
Shorter deliveries, more effective use of floor space—plus the elimination of parts in waiting between operations, fewer setups, less labor, etc—result in higher machine utilization. Customers truly benefit from much less time needed for process control and drastically reduced overall operating costs.

Collision Avoidance System*A world's first— collision prevention in auto or manual operating modes
Novice operators feel safer----get jobs done quicker!*[CAS—a standard feature with the MULTUS]
Programcheck
MULTUSB300
120 min 295 min
100 min 145 min
The Collision Avoidance System (CAS) detects collision per 3D models of the machine components, tools, fixtures, and workpieces stored in the OSP. Thus, if the entered tool, fixture, or workpiece shape differs from their actual dimensions, CAS will not accurately detect possible collisions.CAS will not function when turned OFF (though machine is ON).

● 2 ports are standard. Various devices can be connected, like USB memory sticks for transfer of large NC programs, and bar code readers for production control applications.
● A single screen shows actual position, simulation, machining prep tables, and more. Mode switchover is eliminated; with minimal screen switchovers and cursor movements.
● Program create, machining preps; various operations can be done directly from Process sheets
● Operation is simple even without memorizing G/M codes
● Now you can use Excel® files on an NC controller● Machining instructions and performance reports can be prepared in Excel; compile
instructions and results● Also get zero offsets, tool offsets, common variables and other settings – from Excel
● Direct manipulation of data● Durable panel resists dirt and scratches
● Screen is 2.1 times larger than before● Huge increase in amount of information that
can be displayed

CAPTO C660-tool ATC magazine AbsoScale
Touch setter Steadyrest
Auto cutting-point measurement and tool offset/breakage detection
A large capacity tool magazine to handle a wider variety of workpieces
For highly efficient turning/maching of long workpieces
Okuma high-speed/resolution [0.1 µm] optical absolute position encoders improve machining accuracy by avoiding ball-screw thermal expansion and backlash.
By ATC-delivered, high-precision wireless touch sensor — for superb auto work gauging (dual dia/radius gauging).
In-process work gauging
