Overview

1,050 x 600 mm travel smart machining center for small steel molds

The SMART Ua STEEL is Hwacheon's smart vertical machining center for small steel molds, built for work under 100 mm deep. Its H-SMART S control takes a 3D model and handles shape analysis, CAM, tool path optimization, workpiece setup and program transfer, and keeps computing finishing paths while the machine cuts. It has 1,050 / 600 / 550 mm of travel at 36 m/min, a 1,200 x 600 mm table with a 908 x 408 mm magnetic area, a 120-tool magazine and a 37 kW built-in spindle at 20,000 rpm standard. An automatic workpiece changer with 15 pallets is optional.

Features

013D model to machining in one setupSelect a 3D model and H-SMART S analyzes the shape, computes roughing CAM, optimizes the tool path, sets the coordinate system and sends the program. Finishing and rest machining are computed while the machine runs.
02Bridge structure, 36 m/min on all axesThe bridge-type structure runs high-rigidity roller LM guides on every axis, on a base with a lowered bottom surface. Rapids are 36 m/min on X, Y and Z over 1,050 / 600 / 550 mm of travel.
03Four built-in spindle choicesThe standard spindle is 20,000 rpm with BBT-40, and 12,000 and 14,000 rpm versions are offered; the 14,000 rpm spindle reaches 303 Nm. A 24,000 rpm version runs HSK-A63. All use oil-jet lubrication and jacket cooling.
04120-tool chain magazineThe chain-type magazine uses a swing arm for tool change and fixed-address tool selection. Max tool size is Ø90 mm with adjacent tools, Ø170 mm without, 300 mm long and 8 kgf.
05Built-in magnetic tableHwacheon's patented magnetic table is built into the machine table, so it takes no Z-axis travel. The 908 x 408 mm magnetic area works in four zones, and magnetic clamping avoids distorting the part.
06Automatic workpiece changer optionThe optional AWC holds up to 15 pallets of 400 x 400 mm, transfers up to 80 kgf and takes workpieces up to 250 mm tall. The set-up station is purchased separately.
