SS AL-6XN Machinability

SS AL-6XN is quite ductile in the annealed condition, but it works hardens more quickly and requires more power to cut than do the plain carbon steels. Chips are stringy as well as tough. Approximate speeds for turning and milling are 70 sfm, and for drilling 50 sfm. Machine tools are not flexible and used to no more than 75% of their rated capacity. Both work piece as well as tools is not flexible; tool overhang should be minimized. Tools, fast speed steel or cemented carbide, should be sharp, and reground at predetermined intervals. Turning operations require chip curlers or breakers. The feed rate should be sufficient to ensure that the tool cutting edge is getting under the previous cut in this way staying away from work-hardened areas. This is vital. With heavy cuts slow speeds are usually required. Lubricants for example, sulfur-chlorinated petroleum oil, are recommended in SS AL-6XN machinability. Such lubricants may be thinned with paraffin oil for finish cuts at higher speeds. The tool should not expeditiously on the work piece as this will work harden the material and result in early tool dulling or breakage. All traces of cutting fluid must be separate from prior to welding, annealing, or utilized in corrosive service.
