Design features


The machine bed is made of high rigidity thermal-treated steel to provide maximum strength of the structure. The wheelhead is equipped with a specifically designed electrospindle that is dynamically balanced and fixed on precision bearings.

Wheelhead orientation regulating device

A specific device  is designed to regulate the orientation and allows maintaining constant perpendicularity between the axis of the grinding wheel and the work table, which makes the geometrical trim of the machine easily adjustable to changed settings.

Automated millesimal feeding device

To increase the efficiency of grinding machines with rotary table, it is possible to install an automated feeding device (L11) which allows fully automated grinding cycles. This is a synchronizer device that brings into line the movement on the vertical axle with the rotation of the table; for each 2 rotations of the table the axle movement mechanism performs the given cycle. The maximal amount of removed material during one grinding cycle is 1 mm, which can be performed in steps of 0.005, 0.01 and 0.015 mm.

All machines are equipped with: Electro-permanent magnetic chuck with diameter of 300 or 400 mm and a standard electronic control unit; Coolant tank with filter and electric pump; Safe electrical systems with low voltage controls (24 V); Grinding wheel and holder; Conformity declaration and CE marking.

European quality standards

Full compliance with health and safety policy: all Delta grinding machines are designed and manufactured in accordance with quality European directives and have the according CE marking.
