SPLASH GUARD(STD.)

Even though the spindle head is raised to the maximum height (Z Axis), the end of the

head is still contained within the splash guard ensuring that chips and coolant is not

discharged outside.

Jig Operation Panel

A centralized control panel to operate the jigs during mass production,

allowing simple control without having to move the main operation

panel. Also, the installed emergency switch allows the operator to stop

the machine immediately in case of an emergency.(LCV 30XLB)

Effective Chip Discharge System

Chips are drawn down through the table

grooves and discharged to the left side via screw

conveyor (for rear-discharge chip conveyors).

※ Machines with side-discharge chip

conveyors do not have the screw

conveyor.

Main Operation Panel

Mounted on a guide rail, the OP panel can be moved from

the right edge of the table to the very center, allowing the

operator to look closely at the workpiece.

FULL SPLASH GUARD(STD.)

The standard Full Splash Guard with front, left and right slide covers keeps the chips and coolant

contained near the table, preventing their discharge into the outside environment, simplifying chip

discharge.(LCV 50XLB)

In general, BT30 sized machines use Drum Type tool changing. But due to the vibration from the

heavy head of Drum Types, SMEC implemented an self-developed high-speed CAM system.

X-Axis

Rapid Traverse Rate

In order to increase traverse rate, L/M Guides were used

for all the axes, to offer rapids not normally seen in large

machines. To ensure durability and quality assurance

during heavy-duty cutting, German-made Schneeberger

Roller Type LM Guides were used.

X축 이송

Y-Axis Travel

Moveable Column

With the workpiece fixed, the column

travels in the X and Y-axis and

machines, so even if the workpiece is

large and heavy, there is no overhang

of the X and Y axis, enabling precise

machining.

X-Axis Thermal Expansion Prevention

As long workpieces (in the X-Axis) are usually machined,

small changes in temperature changes the length of the

ballscrew on both ends. SMEC minimizes this change by

fixing both ends and applying pre-tension to the ballscrew.

Servo Motor 1

- Power conversion via direct coupling (without using transfer medium)

- Minimized backlash during axis feed

Guide Way 2

- Improved speed, rigidity and durability

- Better wear resistance than BALL LM GUIDES, ensuring better

precision travel and extended machine lifetime
