6kW CO2 Laser cutting machine [LMRV]

6kW CO2 Laser cutting machine [LMRV]
TANAKA Laser landmark compact body with 6kW oscillator!

The LMR series, improves cost performance of medium to thick mild steel plate laser cutting. The LMR series has gained a reputation for excellent cut quality while operating economically. To further this, the LMR series is improved by increasing the power level. A 6kW oscillator can now be mounted on the LMR series.
An improved optical configuration translates directly to improved cut quality. The LMR series achieves high speed, high output and high efficiency while maintaining low running cost and easiness in use. Further promoting laser cutting in wider varieties of industrial fields.

  *Note: The model LMR has been developed under the concept of starting revolution to make laser the main stream.

The combination of the new oscillator using SANLASER GAS (TF2) and the GOS(PAT/PEND) function improved the possible cutting thickness to 32 mm. Also, machine motion speed other than cutting has been improved by employing the ping-pong functon that performs torch lifting/lowering simultaneously with torch travel in the X- and Y-directions. Piercing time period has been reduced as a whole owing to unique technologies on machine control and gas control.

Features

-Space saving up to 37% (vs. TANAKA existing model).

Succeeded in miniaturization of the machine body through unique design.

-You can handle a big size material.

Seven types of effective cutting width from 2,700 to 5,600 mm are available, which provides no limitation to the effective cutting length and enables continuous un-attended operation of more varieties of materials.

-You can make use of un-attended operation.

The LMRV-TF6000 is equipped with the motorized lens focus adjusting device (LRCII) as a standard accessory, which enables focus position change interlocked with NC controller. Further, the GOS function for automatic adjustment of mixture ratio of shield gas is provided as a standard accessory, which enables continuous cutting.
