Tacchella Multitech: high performance grinding machine
Tacchella Multitech: high performance grinding machine
MULTITECH is the high performance grinding machine designed for crankshafts and camshafts. The two independent wheel heads, the different configurations available (from 1 to 4 wheels per unit) and the optional extras make it a highly flexible machine, able to satisfy multiple machining requirements. On the fixed longitudinal table, there are different types of workhead: universal (fixed or rotating), rotating or double motorised for driving longer drive shafts. The tailstock is hydraulically controlled, with the possibility of the W-axis for automatic compensation of workpiece length differences.Details that make the difference
Cast iron basement
Stabilised, ribbed cast iron basement with peripheral coolant circulation channels. The machine model is designed using advanced 3D parametric modelling techniques and FEM analysis..
CNC Siemens 840D
This powerful CNC allows efficient and advanced management of the machine's functions, facilitating the operator's task by allowing him to have everything under control.
Integration with automated systems
Tacchella Multitech is designed to be easily interfaced with automated loading systems or external robots for maximum productivity Multitech è predisposta per essere interfacciata agevolmente con sistemi di caricamento automatizzati o robot esterni, per ottenere la massima produttività.
Software Tool Operator Package
Our interactive software T.O.P. (Tool Operator Package), dedicated to grinding, guides the operator step by step on how to operate the machine in compliance with safety regulations. The software allows to easily manage automatic grinding cycles, roughing, semi-finishing, finishing and flash hider during plunge grind and reciprocating grind cycles.
This man-machine interface uses a few simple pages with graphic support. The operator can set up operations to perform through guided procedures and the execution of all available workings.
Workhead
The workhead, with fixed and rotating spindle, is perfect for grinding between the centersand between centers on chuck . Manufactured with high-precision bearings, which guarantee the highest roundness accuracy of less than 0.001 mm, the new workhead can be on a swivelling base, with the option of a micrometric adjustment device. Progressive speed variation is by means of a Brushless AC motor, while to facilitate movement during machine set-up, the unit is equipped with a lightening system.
