Metal wire cutting technology has significant advantages and important applications in the processing of watch parts. Watch parts are often small in size and complex in shape, requiring extremely high precision and finesse. For example, the processing of small gear shafts, clockwork shafts, pointers and other parts. The processing accuracy of wire cutting technology can reach the micron level, which meets the strict requirements of clocks and watches for travel time accuracy.
Recently, a Brazilian watchmaker consulted about WEDM machine for processing precision watch parts. The customer provided the workpiece size: 600*600*400mm. According to the customer’s needs, ANTS engineer successfully matched a WEDM–DK7763 for the customer, with a worktable travel of 630*800m and Max. cutting thickness of 500mm. The following are the basic parameters of DK7763:

| Total machine power | kw | 2.5 |
| Processing surface roughness | μm | Ra≤2. 5 |
| Maximum cutting speed | m²/h | 8000-10000 |
| Maximum load capacity | kg | 950kg |
| Machine size | mm | 1800*1400*1700 |
| Machine weight | kg | 2800 |
The following is an explanation by Shanghai ANTS engineer on how to process watch parts with the wire cutting machine DK7763:
First, according to the design requirements, use computer-aided design (CAD) software to draw the precise graphics of the gear.
Then, import the graphic data into the control system of the wire cutting machine.
The control system on the wire cutting machine accurately controls the moving path of the wire electrode wire and cuts according to the preset trajectory.
Since wire cutting is a non-contact processing, it will not produce mechanical pressure on the work-piece, thus avoiding deformation or damage of the gear during processing.
At the same time, by adjusting the discharge parameters, the processing accuracy and surface quality are effectively controlled.
The tooth profile accuracy of the watch gear after processing has reached the micron level, and the surface finish is high, which fully meets the high-precision requirements of watches.
