YAMASA SX  Type Tools are used for the aim of burnishing the stepped-plain shafts, female tapers and flat surfaces. The tools provide as well as surface hardness and at low rate calibration (measurement accuracy) beside of burnishing. The tools provide time saving through a high processing power and speed and this is a motive to prefer  for the serial production.

Tool Structure

SX Type Single Roller Burnishing Tools consist of a connecting shank, precision body which is special designed, roller head which contains  special mechanism parts for long using life and a dial gauges which is assembled for adjusting the force. According to the preference, shank is delivered as Square, Weldon or VDI Shank. Whole shanks are demountable.

Technical Features and Advantages

  • The surfaces in quality of Rz< 1 µm (Ra<0,2 µm) can be obtained
  • It is possible to burnish in different sizes with same tool.
  • Tools can be used in two different ways by changing the shank. Shank of the tool can be dissemble and can be interchanged on the body. So with same tool both shafts and flat surfaces can be burnished. For this reason it does not require to have two other tools for two different surfaces.
  • Used on CNC and  Universal  Lathe Machines.
  • Tool shank and indicator have a special right and left interchange. So the tool can used both on Universal  and CNC  Machines.
  • Tools don’t require settings and when the tool is fixed to the machine it is ready to use.
  • During the operation the tool is fixed and workpiece rotates. Rotation is possible in two directions.
  • Roller burnishing force can be adjusted. So it is possible to achieve high quality and standard roughness values.
  • Special design and spring system apply rolling force consistently. So it provides high quality and standard work flow
  • Roller burnishing of shoulders and other edges is possible up to the end.
  • It is capable to burnish all kinds of metallic metarials up to the tensile strength of 1400N/mm² and to the hardness 42-45 HRC.
  • It is easy to change the spare part.
  • Process time is short.
  • It removes the second machine and personnel requirements.
  • It is enough a little lubrication (oil or emulsion)
  • It does not make sawdust.
