PSG

Machine Feature
◆ Table uses proximity switch for stepless, side to side speed changes and increased convenience.
◆ Table can switch to manual grinding. For safety, manual grinding and hydraulic control cannot be simultaneously operated.
◆ Longitudinal/cross slide ways employ full support design, are precision hand scraped to offer high accuracy and stability on both axes.
◆ Before any machine leaves the factory, it is checked for perpendicularity using a cylindrical angle square.
◆ Imported motor on Z axis (cross) drive ensures accuracy. (on 2A, 3A, AD only)
◆ Full length of slide ways protected from lubricant.
◆ Worktable longitudinal and cross feed parallelism. Gauge is fixed in spindle and placed in light contact with worktable. Standard cross feed results below 0.002mm.
◆ The new hydraulic box with cooling fan, effectively reduce the impact generated by the temperature rise.
