Perfect engineers presents roller burnishing tools [yantra brand] and centreless od burnishing machines. All the mechanical surfaces consist of peaks and valleys of irrefular shapes and sizes. These roller burnishing tools are made of plastic work method in which precision finished rollers are caused to rotate in contact with the work area, which results in some plastic deformation of metal. These tools are very efficient for all type of industries, like automobiles, textile and engineering components, hydraulic and pneumatic components, fans, motor coves, valve seats and guides, bushes, bearing sizes, etc. By using these tools, many advantages can be obtained, such as mirror like finishing, tough work hardened surface, accurate size, close tolerances in taper and ovality, no operator skill required, economical and fast process, low torque and power requirement, no additional machine investment, etc.
