This Delta TP 750 500 is a used flat grinding machine — also known as a surface grinder — designed for precision surface finishing of metal workpieces. Surface grinders are widely used in toolmaking, die-and-mould work, and general precision engineering to achieve tight dimensional tolerances and smooth, flat surfaces on ferrous and non-ferrous components.
The machine is equipped with an electromagnetic chuck measuring 750 × 300 mm and a working table of 750 × 500 mm, with a magnetic table surface of 700 × 400 mm available for workholding. Longitudinal travel (X-axis) extends to 800 mm, cross travel (Y-axis) to 450 mm, and vertical travel (Z-axis) to 600 mm, giving the machine a generous working envelope. Maximum grinding length is 800 mm, maximum grinding width is 500 mm, and maximum grinding height is 425 mm.
The grinding wheel is sized at 400 × 80 mm and runs at a wheel speed of 1,500 rpm, with motor rotation speed at 1,400 rpm. Table speed ranges from 2 to 20 m/min, and cross speed runs from 0 to 30 m/min. Electrical cross feed is rated at 1.20 m/min, while intermittent cross feed spans 2 to 60 m/min. Automatic vertical feed increments are selectable between 0.005 and 0.03 mm per pass, which reflects the fine resolution expected in precision surface grinding applications.
The machine weighs 3,500 kg, indicating a robust, rigidly built construction well suited to stable, vibration-resistant grinding. Two units are available in stock, both located in Portugal and offered in used condition at a price of $7,000 each.
