Sarix Micro-erosion drilling centre can use electrodes ranging from 45 µm to 3 mm
The SX-50 drilling machine from Sarix targets a range of applications, including micro-moulds, according to the supplier.
The company said the unit has a worktable of 510 x 270 mm, and a standard X axis of 200 mm, with 250 mm version available as an option. The Y and Z axes are both 150 mm, it noted. The feed rate for all axes is quoted at a maximum of 600 mm. The table can handle around 20 kg, Sarix said.
The company noted that the unit offers a standard precision of positioning of ±10 µm. Precision of ±2 µm is available as an option.
The SX-50 is said to create perfectly round holes, concentric and accurate holes, offer control of hole taper, have no angle limit, no burning effect, no material alteration, no entrance or exit deformation, feature high quality of surfaces and productivity and suit high-precision finishing.
The company explained that a typical configuration for the unit includes a CNC controller with enhanced automatic configuration, unlimited programming capacity, free and unlimited micro-EDM technology settings, a high quality 8.4 in. TFT colour display, a USB port and an ethernet connection. The company said that virtually up to 16 axes of CNC control within 4 axis on simultaneous motion is available as an option. Other devices in this configuration include a micro-pulse shape generator, a dielectric unit for deionised water or dielectric oil with conductivity and temperature control for mass production and a 70-bar dielectric flushing unit.
Options include the SX-MFPS, micro-fine pulse shape with ultrafine finishing down to a roughness average of 0.05 µm. A micro-deep hole-drilling device with a diameter/depth ratio of 100-150 is also available.
