Adjustable Reamers

A micrometer is used for setting blades to the required dimension. Reaming allowance recommended 0.12mm to 0.17mm. The micrometric scale permits very fine adjustment of blades to correct size. Each division adding or reducing 0.02mm on the diameter. First four sizes covering 13.00mm to 19.00mm are provided with Tungsten carbide Tipped blades for reaming through bores only Extended blades for blind bore are not provided in this range. Instead of Morse Taper parallel shank can also be supplied on specific demand. Additional length of the bore can be achieved by using extension sleeves. The range of 13.00mm to 300.00mm is covered by 17 SAMARS and can be fitted with Blind Bore Blades also 21 SAMARS
  General
  The Self Aligning Machine Adjustable Reamer (SAMAR) is developed to fulfill the requirement of a micro-adjustable reamer.
   
  Outstanding features of the reamer are :
 
  1. It covers a wide range of sizes within one reamer.
  2. It has replaceable tungsten carbide tipped cutting blades.
  3. It has a positive constant float through-out the range.
  4. The float is at the cutting end eliminating special floating tool holders.
  5. It is easy to set size in the machine itself.
  6. No special wrenches or tools are required for setting.
  7. Two-bladed construction, with diametrically opposed blades fully supported over the width of blades allows.
 
  • Greater coolant and chip passage.
  • Lower cutting pressure.
  • Cooler cutting permitting closer tolerance and finer finish of the bore.
   
  CONSTRUCTION OF SAMAR
The blades have a diagonal key way in each. This forms ‘X’ when they are assembled. A diamond guide is located within these key ways. The pair of blades with the diamond guide which has an elongated hole in position between the blades is assembled in a carrier where they are held by guide pin. This pin in Conjunction with the elongated hole in the diamond determines the float of the blades in operation. The carrier is controlled in its longitudinal movement by means of carrier pin which is positional between the Adjuster and lock ring. When this assembly of rings is rotated along the micrometer threads on the shank body, carrier responds by moving the diamond guide in its key way thus expanding or retracting the blades.
   
  SETTING SIZE
Use micrometer to check over blades. Rotate the ring assembly till required size is obtained. Adjuster ring with micrometer reading can help obtaining the correct size quickly. Then lock the position by lock ring. Each division of the micrometer reading on Adjuster ring is 0.02mm.
