HIGHLY RIGID CONSTRUCTION
The M-300's compact body (floor space of the M-300A2: 55 sq.ft./ 5.1m2 features a triangular construction, and its column and bed are made of thick, heavy metal. This assures stable machining by minimizing both machining tremor and forces of repulsion.
The specially designed, highly rigid linear guide greatly increases productivity by allowing a
rapid traverse rate of 78.7 ft(24 m)/min.

The most advanced technology gives the spíndle the power to upgrade speed and precision
POWERFUL DIRECT DRIVE SPINDLE (DDS)
The spindle motor of the M-300 is buílt compactly into the spindle head and directly rotates the spindle. This Direct Drive Spindle (DDS) uses neither gears nor belts to eliminate
vibration, giving the M-300 a high efficiency of rotation and a wide range of spíndle speed (1,100 min-'—6,000 min-'.). High-speed machining is available at a maximum
of 6,000 min-' (AC5.5kW)* A greaselubricant system and powerful
fan cooler ensure that the spindle temperature doesn't exceed 18°F (10°C) above room temperature.
The ceramic spindle taper also contributes to long-term, highprecision machining.
*10,000 min-1 optionally available (Ac7.5/5.5kW)

HIGH-SPEED, HIGH-PRECISI0N TAPPING
Built-in Direct Synchronous Sensor (DSS) enables the spindle motor to
control spindle rotation as accurately as a servomotor can and synchronizes the spindle with
the Z-axis servomotor. The DSS performs high-precision tapping
with tap holders that have a simpler mechanism than conventional tap holders. Capable of a maximum 3,000 min-' spindle speed, the M-300 handles tapping on aluminum die casting.

Proınpt, relíab/e tool change and a speedy, accurate table índex promote efficíent machíning
HIGH-SPEED AUTOMATIC
TOOL CHANGER
(chíp to chíp: 4.3 sec.)
The ATC (Automatic Tool Changer) uses the fixed address, random
access system with 20 standardequipped tools(option:30/40/62/82*).
With the M-300's ATC, programming is easy and tool change is always fast and reliable ( tool to tool: 1.5 sec.). To further improve reliability the ATC incorporates a simple cam
mechanism which reduces the number of inechanical parts and electric outlets. It also incorporates a traction-drive motor for magazine rotation. The ATC is placed on the
Left side of the machine for easy operation and maintenance.
*62ı82-tool option not avaiiabIe for the M-300A2/B2.

HIGH-PRECISION TABLE INDEX
(M-300A)
Mori Seiki's specíal curvic coupling ensures a high-precision table index. The M-300's fast, precíse positioning, high returning-accuracy, and high rigidity greatly increase
machining efficiency. A powertul clamping force of 7,5001bs (3.4t) assures stable heavy cuiting.
Hardened steel reínforces the backs of the pallets carrying and transferring the workpiece.

Wíth the compactly designed APC, the M-300 bríngs high productivity even when used
independently. (M-300A1)

FRONT TURN PALLET CHANGER
(M-300A1)
Even when used independently, the M-300 heightens productivity by
reducing setup time. The front turn pallet change system uses a
180° swing arm to replace workpieces. It firmly places the pallet on the coupling and smoothly carries the finished workpiece to the setup position (replacing time: 10sec.).
The pallet can be manually rotated at the setup position so that workpieces can be easily loaded on and unloaded from a four-side clamping block.

Uniquely desíqned APC further heiqhtens productivity by savíng time, space, and labor
PITCH TRANSFER
PALLET CHANGER
(M-300A2/300B2)
Due to its special fixed table, the M-300 can quickly change pallets by using a uníque pitch transfer system. In this system, a pallet equipped with a workpíece waits next to the workpiece being machined. When the machining is
over, it promptly slides into the machining position to replace the finíshed workpiece with a new one, thus losing no time between machinings. Pallet transfer units and pallet
tilters are all designed to construct an automated line.

HIGHPERFORMANCE PALLET POOL
(M-300A4)
The M-300A4 can be equipped with a space-saving, pallet pool (10 pallets) which rotates vertically.
It takes only 20 seconds to change pallets, and while they are being
changed, tools can also be replaced. During night hours, unattended operation on different
kinds of workpieces is possible.

Automatic compensation function and user-oriented design support the high level of machine performance

PER ECT CHIP DISPOSAL
(M-300A)
When the vertically attached pallet rotates, chips and coolant naturally fall into the chip pocket. This design, together with the complete cover and the placement of the three
axes guideways over the site of machining, solves all the problems
caused by chips produced in an automatic machining process and eliminates thermal distortion of the workpiece. An optional chip conveyor will promptly discharge
the contents of the chip pocket to outside the machining area.
AUTOMATIC
PALLET-ROTATION
CENTER COMPENSATION
The M-300 uses the magnetic sensor to automatically compensate pallet-center shifting caused by thermal displacement from the X-axis.
A sensor placed on the bed detects the position of a magnetic object attached to the saddle. The highspeed skip function measures thermal displacement and compensates, thus achieving precision machining. (Compensation accuracy: ± 0.00008 " / ± 0.002 mm)
EASY MAINTENANCE DESIGN
The NC unit and electrical cabinet are built into the machine to save space and are designed for reliable unattended operation. In addition, unit parts which require daily inspection, such as the pneumatic unit and Iubricanting oil tank, are all located in the rear of the machine for easy maintenance

EASY ACCESS OPERATION PANEL

Operation panel of M-300 (M-300A1: Hung type)
The smart key layout and clear CRT of the operation panel enable anyone to use the
M-300 with confidence. The CRT notifies the operator of operational mistakes, machine trouble, and incorrect input data, thus keeping disruptions in machining to a minimum.

The super-coınpact design is a qreat space-saver (Floor space of the M-300A2: 55 sq.ft./51m2)

The M-300A and 300B are connected so that five sides of the workpiece can be machined without repositioning. The computer controls the combinatíon of M-300s which together act as an ideal, space-saving automated manufacturíng line. The MOR1 HEPS B/M-300 system bríngs together the high productivity of a special-purpose machine and the fiexibilíty of a wide-variety, small-lot manufacturing system. The MORI HEPS B and M-300 combine to form an advanced manufacturing system
responsive to factory automation needs.

MORI HEPS B/M-300 consists of the M-300A2/B2, a pallet stacker, pallet transfer units, and the central control system (host computer). According to the type of workpiece and production quota, the most appropriate production line can be flexibly formed and automatically controlled by the host computer. As seen below, four kinds of line mode are available when three units are used: linked line, independent line, compound line 1, and compound line 11. When the production quota is reduced, the M-3Q0 can be disconnected from the line and used independently oг linked with another line so that the system achieves the highest productivity. If production quotas are increased, new lines can be flexibly and economically added.
