The fly part transfer can be performed by synchronizing the speeds of the main spindle and sub-spindle.
SPINDLE SPEED r/min
RAPID TRAVERSE
Perfect realization of servo-driven feed system.
Scraping of Slideway: Outstanding rigidity for high feed rates.
DAEWOO Products.
TURRET
Superb tooling accuracy and rigidity with fast tool index.
Straight milling head
Angular milling head
The large 12-station heavy-duty turret features a large diameter Curvic coupling and heavy-duty design with unsurpassed rigidity. Turret rotation, acceleration, and deceleration are all controlled by a reliable high torque servo motor.
Unclamp and rotation are virtually simultaneous. Its fast index response reduces the total cycle time required to machine parts.
Index time: 1-station swivel. No. of tool stations: 12.

NEW ROTARY TOOL HEAD
Tooling change in a new dimension.
The new rotary tool head with Preci-flex adapter confirms the high rigidity and application accuracy by simultaneous dual contact between the rotary tool head face and tool holding insert called Preci-flex adapter flange face, as well as tool head pocket taper and the insert taper shank.
New collet application.
Material: Carbon steel SM45C

SAFETY DESIGN FOR HUMAN
The operator's safety is enhanced through the front door with its shock-absorbing laminated glass and double panel construction. The windows without grating also provide a clear view of the machine inside.

NBR

Outside Polycarbonate

The front door opening is detected and locked by a CE certified safety switch. All the automatic operations are effective only in the door-closed status for operator safety. The product is upgraded through hazardous risk analysis, FMEA Failure Mode Effect Analysis, and human safety engineering design.

COMPACT BUT WIDE WORKING AREA
Specifically designed for machining small to middle parts.
X-axis travel: 580 mm
B-axis travel: 1000 mm
Machining range: High-performance machining using a powerful motor with heavy-duty tools.
Tool ø 16 HSS for cutting is powerful and precise even with large workpieces.

ROBUST DESIGN
Slideway width:
X-axis: 272 mm
Z-axis: 360 mm

FEM analysis is used to design a stable body. The heavily ribbed torque tube design prevents twisting and deformation. All guideways are wide wrap-around rectangular type for unsurpassed long-term rigidity and accuracy.
PUMA 240 Series

PRODUCTIVITY
Machining time has been greatly reduced.
High productivity has been realized through PUMA 240 machines. The results from real test cutting are shown in the cycle time table.
These results may differ depending on cutting conditions and strategy.

RELIABLE LONG-RUN MACHINING ACCURACY
The cutting test results shown above are obtained as an example through real test cutting. Results may vary depending on cutting and environmental conditions during measurement. Users enjoy stable performance in all types of operations, from heavy-duty cutting to high-speed machining. Machining operations are highly efficient and precise.

TAILSTOCK DRIVE CONSTRUCTION AND SUPPORT
Each axis is powered by a maintenance-free digital AC servo motor. These high-torque drive motors are connected to the ball body screws without intermediate gears for quiet and responsive movement with virtually no backlash. The X-axis features a double pretensioned ball screw, supported on each end by precision class P4 angular contact thrust bearings. Both axes are driven by large diameter, high-precision ball screws. Each ball screw has been carefully selected to achieve a combination of high accuracy, high rapid traverse rates, and high feed thrust.

TAILSTOCK SPECIFICATIONS
Tailstock travel: 580 mm
Tailstock quill diameter: 75 mm
Taper hole of tailstock quill: MT4
Tailstock quill travel: 80 mm

AUTOMATIC OPERATION SUPPORT
Automatic operation system for increased productivity.
The gantry system makes the PUMA 240 series integrate perfectly with a high-speed gantry loader. The result is a superior automated CNC turning center that will increase productivity in both short and long production runs. It has a dual gripper system (3-jaw for flange, 2-jaw for shaft) to get fast workpiece exchanges and workstockers capable of handling large parts with 14-station capacity.

Dual gripper swivel head Flange module

Max loading weight: 10 kg x 2

Applicable work diameter: 20-210 mm

Applicable work length: 15-150 mm

Max speed (Z-axis, left-right): 150 m/min

• Max speed (X-axis, up-down): 100 m/min

ERGONOMIC DESIGN
Carefully tailored ergonomic operating environment.

Approach to spindle

Adjustable thin operator's panel
The spindle has been ideally located to ensure maximum operability. The easy-to-use operator's panel swivels 90°.

Chip disposal: High maintainability

Tailstock pressure control

Sub-spindle chucking pressure control

ECO-FRIENDLY DESIGN
Perfect integration to care for the environment of humans and the Earth.

Less waste lubrication oil extends the lifetime of coolant water and reduces grime and offensive smells inside the machine.

A belt-driven type oil skimmer removes waste oil from the coolant tank.

Rigorously designed, manufactured, and tested machine covers prevent coolant leakage under any condition.

PUMA 240 Series

High Compact CNC
Realized through LCD display with integrated CNC and a flash memory card interface as standard features.

Provides many support functions for set-ups, such as tool measurement, workpiece measurement at the original point, and workpiece measurement inside the machine.
