The machine adopts a careless way through oil superfinishing cylindrical roller, needle, needle, dowel pin and the valve core thereof round surface, can efficiently improve the roundness and geometrical precision of the workpiece surface, reduce the surface roughness of workpieces. High efficiency, high accuracy and high reliability. Through the special design and processing of the guide roller, a variety of roller convexity types such as straight line, semi-convex, full convex and logarithmic type can be obtained.
Widely used in bearing, automobile, motorcycle, oil pump, hydraulic parts and other industries, especially suitable for cylindrical and tapered roller superfinishing.
Processing technology: the user prepared the oil stone, will install the equipment, according to the requirements of processing precision and inspection project, the test piece continuous processing 50 pieces of assessment, meet the requirements.
Processing objects: cylindrical roller, can be processed linear, semi-convex, full convex and logarithmic type and other convex types, can be extended to taper roller and ring outer diameter and other kinds of workpiece superprecision machining.
Control system: the machine tool adopts PLC control, the touch screen dynamic display, has the fault self-diagnosis function, the system is stable and reliable, adjust, operate, the maintenance is convenient. The action of machine tool is controlled by pneumatic system.
Construction structure: when the roller is not changed, the change time is < 10 minutes; The guide roller is < 1 hour.
Guide roller: the guide roller is used in pairs to ensure the penetration speed of the workpiece on the guide roller, the two guide roller stagger the Angle and adjust the distance of the guide roller according to the specific size of the workpiece. Guide roller diameter: 120 mm Φ; Effective length of lead roller: 730mm; Guide roller speed: 15 ~ 200r/min
Filter system: using magnetic separator and sponge and pressure filter filter, filter precision 5 mum.
Pneumatic system: water vapor separation, oil and gas atomization; Maximum pressure of pneumatic system:≤ 0.6 MPa; 8 superfine cylinder; The pressure is adjustable in 0 ~ 0.4mpa and can be adjusted independently and up and down.
Oscillation system: adopt mechanical double eccentric mechanism, with high oscillation frequency, momentum and 0, the overall vibration is small; Oscillation frequency: ≤ 1500r/min stepless speed adjustment; Oscillation amplitude: 0 ~ 2mm; Height: 115mm; Pressure cylinder: quantity 8; Piston stroke: ≤ 20mm.
Bedstead: the bed is made of casting structure, the design of the inside of the bed frame is reasonable, the rigidity is good, the shock absorption is good, after the strict aging treatment, completely eliminate the internal stress, not deformation.
Documentation: instructions for use of random parts and components of important electrical appliances; Pneumatic lubrication chart; Electrical wiring diagram; Main standard parts of machinery (including model, quantity and origin, etc.); Schematic diagram of main component assembly; Details and quotation of spare parts and vulnerable parts.
Machine color: according to the requirement of color card.
