Overview

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

The Hi-M G1 Pro is a double column vertical machining center for dry graphite electrode machining, built to strict standards from frame machining through assembly and accuracy adjustment. Hwacheon applies additional grinding to the main frames and fits C3 class ball screws, X / Y / Z linear scales (0.05 µm) and HTDC thermal displacement control as standard. It shares the Hi-M G1's 750 / 600 / 350 mm travel, 750 x 620 mm table, 16-tool ATC and 9.5 kW, 24,000 rpm HSK-E40 built-in spindle. It runs a FANUC 0i-MF control with a 15 inch display.

Features

01Ground frames, C3 ball screws, linear scalesMain frames get additional grinding to tight tolerances, the ball screws are C3 class, and X / Y / Z linear scales (0.05 µm) are standard.
02HTDC thermal control standardThermal sensors in the spindle and frame feed the HSDC and HFDC systems, which correct spindle and frame displacement during long runs. On the Pro both are standard.
03Dust 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.
04Dust 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.
0516-tool servo magazineThe fixed-address rotational ATC is driven by a servo motor and holds 16 HSK-E40 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 Pro. An automatic side door is also optional.
