The FSG-C1224CNC profile grinder from Chevalier is designed to meet the grinding requirements of intricate profile and mold component applications. It is suitable for use in the aerospace, automobile, electronic, medical, machine tool and defense industries.
The grinder’s table accommodates loads as heavy as 920 lbs, with a maximum grinding length of 24" and width of 12". Maximum distance from the table surface to the spindle centerline is 24", with an X-Z travel of 32" × 16". The spindle is supported by six angular contact bearings and is air-cooled to minimize temperature increase and ensure accuracy. Grinding spindle speeds range from 500 to 3,500 rpm with an AC servo power rating of 30 hp. The machine uses a standard grinding wheel measuring 14" in diameter and 3" wide with a 5" bore.
The grinder features a single-piece base casting to promote rigidity. The column and wheelhead traverse structure are on precision roller bearings, and the hardened and ground guideways are preloaded and driven by a precision ballscrew for precise positioning. Cross-feed and elevating axes are positioned by precision ballscrews with an AC servomotor for improved accuracy. The elevating encoder device mounted on the top of the elevating ballscrew can directly encode the down-feed amount, eliminating error. The machine’s column is driven by precision ballscrew and has a FANUC AC servo control system.
The FANUC 0iMD control enables full automation for grinding multi-shaped workpieces and completing the entire grinding process in one cycle. The control panel features an 8.4" TFT color LCD screen that can display the grind position and program execution status for monitoring. LEDs indicate main power, machine zero, end of program and other notifications.
