Precimar 828 CiM 1000 Precision length measuring machine
EN
The 828 CiM precision length measuring machine is an Abbe compliant comparator mounted on highly homogeneous rigid granite in a horizontal configuration.
  • Electronically controlled measuring force generation
  • Motorized measuring spindle control with joystick and automatic contacting
  • Air bearings for smooth positioning of measuring slide, counter bearing and object table
  • Sensitive adjustment in 5 axes, and object table with a loading capacity of 25 kg
  • Motorized object table height adjustment via joystick or CNC
  • Maximum measuring accuracy
  • Fast and reliable measurement
  • Exceptionally low length measuring uncertainty for precision parts and gage monitoring
  • Compliant with Ernst Abbe's comparator principle
  • Online temperature monitoring
  • Software-supported measuring force generation, especially advantageous for thin-walled workpieces and gages
  • Semi-automatic bore and inner thread measurement
  • Measuring and evaluation software runs under MS Windows®, 828 WIN
  • Patented measuring procedure
  • Aerostatic guides for all slides mounted on the machine bed ensure extremely low measuring uncertainties
  • Movable measuring spindle mount via a spring parallelogram free from play and friction
  • Electronic measuring force adjustment and automatic contacting – largely eliminating subjective influences and avoiding unintended collisions with the testpiece
  • Possibility of calculating measuring result down to measuring force 0 N (dynamic measuring)
  • Technical data
  • Applications
  • Accessories
