The Grinding machine with swivel table, ideated by our Workshop to grind big-size surfaces, was on show for the first time in April 1982 at “Milan Exhibition”. Ente Fiera includes this new Grinding Machine among the “Highlighted Novelties” publishing it on the magazine "Milan Exhibition".

This first model of grinding machine with swivel table is afterwards modified to meet new technical requirements. The innovative feature of this surface grinding machine is given by the synchronization of the table motion with the manual one of the wheel head.

The perfect synchronism allows using fully the work field of the wheel. Therefore, it is possible to grind large surfaces. The model of grinding machine with swivel table we produce can grind surfaces of mm 600 x 300.

The particular motion determines some grinding lines with peculiar characteristics: the straight line passing through the cross points of the lines made by the wheel is always perpendicular to the two longitudinal sides of the table. The grinding machine is also provided with registration dowels and screws, to maintain the correct assett and to offer optimal performances along the years.

This vertical-axis Grinding machine is provided with:

CAST IRON BED to maintain the geometric stability of the grinding machine in time, too. HARD CHROMIUM-PLATED CAST IRON COLUMN, protected by bellows and supported by four adjustable precision bearings, broadly sized for this type of grinding machine with swivel table. Three-phase MOTOR air-cooled by double jacket, to prevent the overheating of the grinding machine motor during continuous machining and to keep the temperature of the motor shaft and of bearings constant. Hardened, ground and dynamically balanced SHAFT, supported by precision ball bearings, widely sized for this type of grinding machine with swivel table and self-adjusting by means of springs for the backlash preload, to absorb thermal expansions. VERTICAL TRANSLATION SCREW supported by opposite and adjustable ball bearings, with apt motion for maintaining, in this model of grinding machine with swivel table, the wheel work field free from hindrances and for avoiding dust depositions. Metal BELLOWS for a better protection of the vertical translation screw of the grinding machine. Opposite bronze NUTS, for the recovery of the eventual wear in time of the vertical translation screw of the grinding machine with fixed table. REGISTRATION DOWELS positioned at the column base, on the column support and on the wheel motor, to re-align the grinding machine to the axis, obtaining parallel surfaces also in time. HANDWHEEL of the grinding machine, supported by three bearings and engaged on the screw by means of a pair of helical gears, equipped with graduated drum, supported by a trust bearing, for a manual stock removal of mm 0.01 – 0.02 – 0.03 for each single pass. The rapid feed per handwheel turn is mm 2. KNOB WITH JACK, for the programmable micrometric feed of mm 0.01 – 0.02 – 0.03 – 0.04 per pulse, which allows a simple use by avoiding the constant increment control. SLOTS to permit the maximum use in height of the work field of the grinding machine wheel and to clamp non-magnetic parts and accessories such as: magnetic chuck and self-centering chuck. Low-voltage CONTROLS, protection, indicator light and all requisites to comply with safety and conformity regulations provided for this type of grinding machine with swivel table. HANDLES, SHAPES AND SIZES of the grinding machine with swivel table designed to meet the current ergonomic recommendations for work.
