GFM 4473: X=440 mm, Y=730mm, Z=160mm ........................................ Application Example
Series GFM are stable C-frame-type CNC Machines made of light-weight profiles. All linear axes run on grinded steel shafts with linear ball bearings. Clearance-free ball screw drives with hardened and polished 5/8"-16 spindles with a pitch of, optionally, 5 or 10 mm are used as drives.
The linear axes are driven by powerful and robust stepping motors in easy-to-maintain drive modules. The machine table, which is firmly screwed with the underframe, is made of plan-milled precision T-nut profiles. It provides optimal clamping possibilities for the most different and workpiece holders and devises. The protective hood, which features Perspex-lined glass and a swivelling door made of aluminium profiles, constitutes a closed working room with hood locking.
The complete control and power electronics is integrated into the underframe, wired ready for connection. The PC control under Windows with RS 232 interface is executable on each standard PC. The control offers three relay switching outputs, AC 230 V/50 Hz.
The Precigrave base units of the Series GFM 4433 are ideal for applications in the fields:
3/4/5-Axis milling/ Engraving/ drilling/ dispensing, CNC Engraving on large work pieces
