Built to order. Ask for lead time.

Overview

750 x 600 mm travel, 24,000 rpm graphite machining center

The Hi-M G1 is a double column vertical machining center for dry cutting of graphite electrodes. It has a 9.5 kW built-in spindle to 24,000 rpm with an HSK-E40 taper (BT-30 optional), a 16-tool ATC, and a dust collector with a sealed roof and an air curtain that keeps dust out of each axis. Travel is 750 / 600 / 350 mm over a 750 x 620 mm table rated for 400 kgf, with 25 / 25 / 20 m/min rapids. SIEMENS-828D is standard, FANUC 0i-MF is optional, and a robot interface is available with the FANUC control.

Features

01Dust control for dry graphite cuttingA sealed roof collects dust from dry machining and an air curtain keeps fine dust out of each axis. The door design makes cleaning and draining slideway lubricant easier.
02Dust collector standardThe dust collector uses 12 cartridge filters with a 50 m² filtering area and automatic air-pulse cleaning, driven by a 3.7 kW motor.
03Dust-proof built-in spindleA dust-proof and waterproof 9.5 kW built-in spindle runs to 24,000 rpm. Bearings are grease lubricated with no replenishment needed, and the spindle is oil cooled.
04Double column with wide LM guidesThe double column frame runs wide LM guides on X, Y and Z, with servo motors coupled directly to high-precision ball screws.
0516-tool servo magazineThe fixed-address rotational ATC is driven by a servo motor and holds 16 tools up to Ø63 mm, 200 mm long and 3 kgf. Tool change is 22 seconds tool to tool.
06Robot interface optionHwacheon offers a robot interface for the FANUC control as an option on the Hi-M G1.
