L.K.

ALWAYS COMMITTED TO CUSTOMER SUCCESS

Product Introduction

The horizontal CNC lathe LT/LTR series features high precision, high efficiency, and high stability. It supports X-axis and

Z-axis linkage, tool wear compensation, and other functions. With strong process adaptability and high machining efficiency, it is widely used in the automotive parts, aerospace, and general parts industries, suitable for precision machining

of large-batch parts.

The LTR-8M series turning center is equipped with a power turret and power tool holders that enable tool rotation. The

spindle features C-axis indexing and orientation functions, allowing drilling, milling, and tapping at any position on the

end face and circumference. Almost all machining operations for the turning center can be completed in a single clamping.

Customer Cases

LT-6 Turret

30° flat bed with inclined saddle design; electromechanical-hydraulic integrated layout; compact structure and high rigidity.

Modular design, flexible and diversified to efficiently meet customer needs.

Standard 8-station servo turret with

high and stable tool disk rotation

torque, fast tool change, suitable for

heavy cutting.

Main Spindle

The f ron t bea ring o f the spindle

adopts high-precision double-row

cylindrical roller bearings, ensuring

sufficient rigidity and accuracy of the

spindle.

High Rigidity

The X-axis feed is designed at 30° to the horizontal plane,

lowering the center of gravity of the machine, providing a

compact structure, high rigidity, and smooth chip evacuation.

X/Z axis linear guides offer good dynamic characteristics,

stable machining accuracy, and high rapid traverse speed.

Castings are analyzed using finite element analysis (FEA) with

reasonable cavity rib layout for strong deformation resistance.

X/Z axis ball screws adopt a pre-tension structure to

reduce the impact of temperature rise on screw accuracy during machining.

Integrated high-rigidity spindle, low noise, high precision, long service life.

The machine adopts full-enclosure sheet metal for

excellent protection.

Chuck

The LTR series adopts Taiwan-imported 3-jaw hollow

chucks with high clamping accuracy, ensuring stability

and accuracy during machining. Excellent centering

accuracy helps reduce machining errors and improve

workpiece precision and surface finish.

Hydraulic System

The hydraulic station precisely controls the clamping

and releasing of the chuck and tailstock by controlling

the switching and adjustment of hydraulic valves. The

hydraulic system uses a variable vane pump, and the

hydraulic oil tank is placed at the rear of the bed, isolated from the outside by protective covers. Each hydraulic

circuit adopts a stacked valve installation method, compact and easy to install. The pressure of each actuating

cylinder in this hydraulic system can be adjusted separately and is equipped with pressure protection devices.

The hydraulic oil tank is equipped with an air-cooling

device.

Pneumatic Device

Pneumatic panels and cylinders are from Taiwan Airtac, providing power for pneumatic doors to achieve automation.

Guideways and Ball Screws

High-precision ball screws and guideways: High-quality ball screws and guideways, directly driven by servo

motors, achieving excellent running accuracy.

High-precision spindle cylindrical roller bearings:

High-quality imported cylindrical roller bearings, combined with high-precision spindles, achieving excellent

rotation accuracy.

Quantified process standards: Operation instructions

are formulated for each assembly process. Torque

wrenches, laser interferometers, and other equipment

are used to ensure assembly accuracy. Reasonable processes and steps are set, and operation instructions are

strictly implemented to achieve high overall

Servo turret

The servo turret is fully equipped and capable of

achieving intelligent production. The adoption of an efficient servo turret ensures its strong processing capability and stable tool change performance even under

high-speed operation.
