CHEVALIER FSG-1640ADIV surface grinding machine

CHEVALIER FSG-1640ADIV surface grinding machine was built in 2022 in Taiwan by Falcon Group Co., Ltd. The machine is used for precision grinding of workpieces with a maximum weight of 440 kg. A number of state-of-the-art technical solutions, combined with extensive equipment, make it the best choice for professional production applications.

Grinding is performed fully automatically on a large electromagnetic plate or directly on the work table. The work table is hydraulically driven and moves on ground and induction hardened guideways. To achieve the highest machining accuracy and precision, the CHEVALIER FSG 1640 ADIV magnetic surface grinding machine is equipped with dynamic balancing and automatic dressing of the grinding wheel.

During grinding wheel dressing, the work table automatically positions itself where the diamond tools are and compensates according to the operator’s settings. Balancing, in turn, reduces the vibration of the grinding wheel and completely eliminates the ripple effect of the workpiece surface. Both of these solutions, combined with the variable spindle speed, ensure a constant surface speed regardless of the changing diameter of the grinding wheel.

Daily operation of the machine is facilitated by the advanced iSurface NC controller. This high-quality, PC-based industrial unit has a number of useful features, such as a variable frequency drive that automatically adjusts the linear speed of the grinding wheel. The wheel balancing, in turn, is monitored by a built-in indicator which, if necessary, informs the operator that this action needs to be repeated.

The FSG-1640 ADIV magnetic surface grinding machine is offered with an extensive range of equipment, consisting of, among others, an indirect measuring system in the Y and Z axes, a 1000×400 mm electromagnetic plate and a coolant cleaning device with automatic filter and magnetic separator. The total weight of the machine is 3500 kg.
