GCL-2 SERIESHigh Speed CNC Turning Centers

Our achievement has lasted over 25 years with over 7,000 units sold around the world.

From Classic to Evolution

We want to go far beyond our customer’s expectations and continuously pursue the ultimate performance.

The classic

The Evolution

The GCL-2 ser ies i s based on our most advanced tur ning

technology and outstanding manufacturing capability, providing

users with a high C/P value and high stability performance.

HIGH PERFORMANCE CNC LATHE

Based on over 25 years of manufacturing experience and top CNC turning

technology, the all new GCL-2 series provides you with high stability of

heavy cutting and precision turning capabilities. With high horse power,

high rigidity structure and precision servo indexing turret, the GCL-2

series can meet with all sorts of cutting needs for today and tomorrow.

( GCL-2BL series model shown. )

All new series is equipped with high technology servo indexing turret. Tool change is faster

and accurate to provide excellent working efficiency.

The 4,500 rpm high torque spindle is driven by a 15 kW wide range motor which easily

meets all sorts of heavy duty cutting requirements.

X and Z axes are of super-rigid box ways with heat treatment and precision machining to

provide the needed stability for heavy-duty cutting.

The high rigidity tailstock is equipped with MT#4 live center and the spindle thrust can be

adjusted by the hydraulic pressure to meet with various cutting requirements.

By using Finite Element Methods ( FEM ), optimal reinforce ribbings are

directly cast into the one-piece bed structure. Mechanical rigidity has been

increased by more than 30% when compared to conventional designs.

The GCL-2 series is capable of performing super heavy-duty turning and

maintain long-term super high-precision accuracy.

HIGH RIGIDITY CONSTRUCTION

Extra wide hardened and ground box ways are directly formed into the

machine bed and saddle during the casting process ( Box way hardness can

reach up to HS70° ). They are precision machined and widely spaced for

maximum strength. The box way design also provides the rigidity needed

for heavy duty and interrupted turning applications.

Built to endure years and years of rigorous high production turning, the

heavily ribbed, one-piece thermally balanced bed and casting components

are of FC35-Meehanite casting ( industry standard is FC25~30 )

The low center of gravity heavy-duty

bed and 30° slant wedge saddle design

provides smooth chip disposal under

long working hours.

All spindle and servo motors, including

drives, are Fanuc αi series components

to ensure peak machining performance

and accuracy.

The heavy-duty servo indexing turret uses the most advanced turning technology. Index

movements are single step, without pauses, no matter how many stations are skipped.

Achieving 0.2 second indexing times for adjacent stations and 0.5 second for stations at

the opposite end of the disk. Tool change efficiency is 50% greater than the former model.

The curvic couplings provide a large contact area

and are designed with an auto–clean feature not

seen on traditional couplings.

Ø 180 mm diameter super high precision 2-piece

CURVIC couplings accurately position the turret

disk and 4,000kg of clamping force ensure

abundant turret rigidity for all cutting conditions.

Generating twice the torque output of standard motors, the A/C, constant output, wide-

range Fanuc αP22 high-torque i series motor is rated at 15 kW ( 30 min ). This double bind

motor is designed to reach full output at 1/2 the RPM of standard motors, providing the

ability to take heavier cuts in the lower RPM ranges.

Rear – Double roller × 1

P4 grade ( Class 7 ) super-high precision bearings are

directly assembled for maximum level of support and

precision. Bearing configuration is designed for super

heavy-duty cutting with ultra-smooth performance and

long term durability with a higher level of accuracy.

The heavy- duty headstock is of

one-piece casting reinforced with

heat dispensing fins.
