PCB UV Exposure Machine (UV260D)

  • Model NO.: UV260D
  • Trademark: Torch
  • Dimension: 510*410*150mm
  • Origin: Beijing. China
Exposure time: Photo script and line script is usually 60-90 seconds, the manuscript is 70-120 seconds, semitransparent script increase 10-30 seconds (electron sensitive board is better), other underpans which are low sensitive increase exposure time 1.5-3 times. 2. To open vacuum clamp, please use vacuum spanner outward and upward. 3. Put sensitive board on the glass of vacuum clamp, and then click inspiratory mouth, keep 1-3 cm distance. Please with JE close in scripts and then adhesive tape paste margin, put the sensitive board into scripts. 4. Close vacuum clamp and confirm it has been locked. 5. Open vacuum pump power, after drawing out vacuum, close cover, open light up or down or up and down open at one time. A. KVB-30A Red LED indicate exposure process, when all red LED are off and yellow LED are on which indicate finishing exposure process. B. KVB-30D The number of LED indicate exposure seconds, when finishing exposure, the calculagraph stop and sound tip for 2-3 seconds. KVB-30D When adjust preset time in the exposure process, it is easy to break exposure off, please press intermit time to provide exposure reference. 6. Close vacuum PUMP power, open cover, wait for several time and then make vacuum clamp outward and upward, after relieving vacuum, it is easy to open cover and take sensitive board. 7. If continue to exposure, please press RE-EXPROSE to pass over operation process. If stop exposure, please turn off all switches on the panel and then closer cover. Technology parameters: Voltage 100V; 110V; 220V; 240V Frequency 50/60HZ Input 200W Light source Chemical lamp 15W*6 Mask Area 220*370mm Dimension 510*410*150mm Weight 12KG

Machinery shell with gearbox shell processing
Machinery for typical gearbox shell body parts, main processing plane and hole system, to ensure that the size of the hole in the process of machining precision and position accuracy, handle the relationship between hole and plane. Should follow the principle of surface before hole, namely first processing box on the datum plane, and then to datum plane positioning processing other plane, then processing hole system. Because of the planar area is large, with its positioning can ensure reliable positioning, clamping and firm, and therefore easy to guarantee machining precision holes. Secondly, cut off the casting surface uneven, create conditions to improve the machining precision of holes, facilitate and adjustment of the knife, is conducive to protect the cutting tool. Processing technology should also follow the principle of separate rough finish machining.
