Burnishing Reamer

Burnishing Reamer : Highlights

(A) Blade with appropriate cutting edge geometry. The guide pads are positioned to absorb and utilize the radial and tangential force. Hence, overall effect is an efficient material removal and size - control of the bore.

(B) Axial parallelism and ovality is within 1 to 3 m and is maintained over the entire bore length. Same accurracy is obtained in broken and interrupted bores with extended guide pads.

(D) Guide pads while controlling the cutting edge, burnish the whole surface by exerting a counter force to the cutting action.

(E) The only wearing part in Burnishing Reamer is the Blade. This blade can be used from the both sides, Resharpened & Replaced.

(F) The guide pads require a constant lubricant film for longer life. Any commercial coolant emulsion (1:9 mixture) serves the purpose.

(G) Stock removal: Burnishing Reamer reams in straight line and does not follow the pre-machined bore. For good allround finish, stock removal should be 0.15 mm i.e. 0.3 mm on dia.

(H) Cutting Speed: Standard speed 12-25 m/min. (Surface speed). Trials with different RPM, feed abd rake angle of the blade should be carried out for achieving required finish, accuracy and production.

(J) The adjustment is only within the tolerance. The range given is to inform the Morse-Taper and reaming length available.
