Grinder combines speed with precision and controllability

Chevalier's new FGP - 608LM grinder combines linear motor drives, 3 axis closed loop electronic control, and structural stability to deliver up to 2.5G-accel/decel speeds, 720 times per minute reciprocating rate at 5/8 in. stroke, and 328-fpm table speed. Heavily ribbed solid Meehanite cast iron castings with hardened and ground linear ways on the XYZ axes coupled with a heavyduty spindle allows the machine to operate without vibration during the high-speed, close-tolerance machining process. Linear motors are cooled by an oil chiller to minimize thermal displacement and maintain high-levels of precision. Machine features include a 6 x 8 in. work area, 0.0001 in. repeatability in the X axis, and 0.000040 in. repeatability in the Y and Z- axis. In addition, the machine comes with a 2,000-10,000rpmspindle speed. Chevalier offers two control options; a FANUC 18iM control with FANUC linear motors, or Chevalier's own Smart control using Siemens linear motors. An easy to reach closed loop electronic control pendant features conversational programming, G-code, custom programs, and options for networking. With combined speed and accuracy, the machine guarantees accelerated cycle times, reduced non-grinding time, and increased throughput. The adjustable grinding head swivels with ±5° adjusting range to meet various grinding applications. The slim design also enables an operator to easily load and unload workpieces, work closer to the table, and visually monitor the grinding progress.
