HIGH SPEED & HIGH PRECISION MACHININGPROCESSMedium/Large Graphite Machining Center

HIM-G1/G2+ delivers high-speed, high-precision machining for dry cutting of

graphite electrodes used in aluminum die casting process. It delivers quality

machining by applying the highly dustproof and waterproof spindle and the

optimum dust reduction system. This system blocks the dust scattering and

entry of fine dust created during the machining process. HIM-G1/G2+ is easy

to use due to its various add-on functions and enhanced user convenience.

Vertical Machining Center for Graphite

5Vertical Machining Center for Graphite : HIM series

Spindle with Built-in Motor

A high-power motor is integrated into the spindle shaft without any

parts that transfer power between the motor and spindle. It minimizes

vibration, noise, and power loss during high-speed rotations,

increasing machining efficiency. Also, the bearing grease lubrication

system and synchronous temperature control minimize the influence

of external temperature variation and improve smoothness.

Dust-proof (Air curtain system)

Air curtain system blocks the entry of fine dust into the feed system.

(Air volume: 2 bar)

Dust Collector

The scatter prevention system against the source of graphite dust has

been implemented.

● Air volume

● Vacuum cleaner (user-friendly hand hood) [Opt.]

● Filter (Std.) HIM-G1 : 16ea (Dia. : Ø160mm, Length : 400mm) HIM-G2+ : 24ea (Dia. : Ø145mm, Length : 500mm)

HIM-G1 : 5HP (60m/min, 250mmAq) HIM-G2+ : 10HP (120m/min, 500mmAq)

Tool Length Compensator (Optional)

Tool length and diameter are measured and compensated

automatically during the operation, minimizing non-cutting time and

allowing any operator to reproduce high-precision results regardless

of their work proficiency. Also, it detects any faults in the tools and

prevents accidents before they happen.

Interactive Machining Programming

Siemens-828D system has been adopted as a standard to provide

flexible programming input.

It also provides convenient controls and efficient functionalities for

high productivity.
