The originally invented method of fluid pressure control in a hydrostatic burnishing tool is characterized in that the tool is hydraulically powered by a lubricating coolant supplied from a spindle (13) to the main body of the tool (1) through a filter (9). The fluid is then directed to micro-hydraulic control unit (10) and it is divided. The flow of lubricating coolant with pressure p 1 controlled by micro-valves (11) that control one-way actuator consisting of piston (2) and cylinder (4) is directed over piston (2). The flow with pressure p 2 controlled by micro-valves (12) that control pressure in hydrostatic bearing is directed to burnishing element (6) whose bearing is supported in bearing bush (7). The originally invented hydrostatic burnishing tool is equipped with a main body of the tool (1), a piston (2), and a cylinder (4) that make up a one-way actuator, a burnishing element (6), a bearing bush (7) and a ring (8). The tool is characterized in that it has a micro-hydraulic control unit (10) powered by a lubricating coolant, piston (2), micro-valves (11) that control one-way actuator consisting of piston (2) and cylinder (4), micro-valves (12) that control pressure in the hydrostatic bearing and it has a bearing of burnishing element (6). The micro-hydraulic control unit (10) is mounted in main body (1) of the tool and cylinder (4), encasement (5), piston (2) and bearing bush (7) contain a pipe supplying the lubricating coolant from micro-hydraulic unit (10) to burnishing element (6). |
