  • Precision Positioning Switches Case Study : Detected Deviation of the X-Y Axes of a Machining Table
    Metrol's IP67 waterproof "Precision Positioning Switch" can demonstrate 0.5 repeatability even under harsh environment in machine tools where coolant and cutting chips splatter.
  • Putting Together a Plasma System
    Choosing a plasma power supply is one thing; putting together an entire system is something else altogether. A complete plan includes an X-Y table, CNC system, software, and fume control. Putting together a complete plasma cutting system can be a daunting task. It starts with the machine
  • MICRO: Products
    by other industrial solid-state lasers. The low-noise unit has pulse power variations <4% peak to peak. With an average power >8 W at 1064 nm, the laser offers high throughput for high-speed applications based on galvanometer scanning or rapid x-y table motion. The Q-switched laser produces
  • Improving Motion Positioning With Dual-Loop Control and Scurve
    encoder (on the motor) to be used to stabilize the motion, while the second (on the stage) is used for positioning accuracy, with all of the control details handled by the Magellan chip. Dual-loop corrects automatically for mechanical errors from backlash, lead screw or table assembly non-linearities.
  • Medical Device Link .
    the machine to achieve high precision levels. The manufacturer has employed hydrostatic rather than linear drives in the machine design because the former do not create a whipping cogging effect. Hydrostatic guideways lift the machine table 18 um, thus there are no metal-to-metal contacts or wearing
  • Machining - Five-Axis Machining: What Are The Benefits and How Can You Achieve this Capability? - 09/07
    or Z axes. There are currently three main ways of achieving simultaneous five-axis milling: (1) a dedicated five-axis machining center; (2) a tilting/rotary or trunnion table; and, (3) a spindle head attachment. There are currently more than 15 original equipment manufacturers of five-axis
