Come calibrare gli utensili su macchine utensili CNC
La calibrazione degli utensili per macchine utensili CNC è un'abilità importante nella lavorazione. La precisione dell'impostazione dell'utensile determina la precisione della lavorazione del pezzo, e l'efficienza dello strumento di calibrazione influisce direttamente sull'efficienza di lavorazione della parte. Il presetting utensile è molto importante per le operazioni di lavorazione della macchina utensile.
CNC milling of precision hardware parts
The CNC milling machine can perform milling processing of complex-shaped hardware parts. Milling is to fix the blank, and use a high-speed rotating milling cutter to move on the blank to cut out the required shapes and features. La fresatura tradizionale viene utilizzata principalmente per fresare elementi di forma semplici come contorni e scanalature. CNC milling machines can process complex shapes and features.
Broaching of part holes
Broaching of aluminum alloy, acciaio inossidabile, copper and titanium alloy parts:
Broaching is a highly efficient finishing method. In addition to broaching round holes, it can also broach through holes and internal keyways of various cross-sectional shapes, come mostrato in figura 7-19. The achievable dimensional tolerance grade for broaching round holes is IT9~IT7, and the surface roughness value is Ra1.6~0.4μm.
Turning and milling combined processing of cylindrical parts
In order to meet the different machining needs of customers, Methods Machine Tool Company provides two models of Nakamura Tome machines equipped with B-axis. The STW-40 machine tool with a standard 40-station automatic tool changer is designed to process large and heavy parts. Such as: castings and forgings, and can process workpieces up to 17 inches in diameter. Tuttavia, in response to customer needs, Methods Machine Tool Company can now provide a smaller model of B-axis machine tools, namely NTJ (B-axis turret).
Surface finishing of metal parts (trattamento superficiale)
Mechanical surface treatment of parts
It mainly includes wire brush roller polishing method and shot peening method. The polishing method is that the brush roller is driven by the motor, and the brush roller rotates at a high speed on the upper and lower surfaces of the strip in the direction opposite to the movement of the rolling piece to remove the oxide scale. The brushed iron oxide scale is washed away with a closed circulating cooling water washing system.
