Gear Rack for Machine Tool table Drive

SECTOR
  • Machine Tool Manufacture
GRADE
SUITABLE TO REPLACE
  • Sand Castings
ADVANTAGES
  • Better machinability – self lubricating chip generating
  • Higher wear resistance
  • Higher tensile strength
  • Better surface finish
  • Scrap reduction
  • Shorter deburring time
  • Good vibrational absorption
  • No shrinkage or porosity
  • Finer grain structure than sand casting
COST SAVING
  • No pattern costs
  • No rejected parts
  • Extended tool life because of no sand inclusions and self lubricating properties
  • Smaller machining allowance
