Automated Centerless Grinder

Description

The GT-610 CNC is the complete “lights-out” centerless grinding solution for applications where a high degree of automation, data gathering and gauging feedback is required. Built on a mineral cast base for rigidity, vibration and thermal stability, the GT-610 CNC weighs over 8,000 pounds.

 

The unique infeed centerless grinding technology shine in this higher precision machine tool, able to process challenging components, such as titanium aerospace fasteners, arthroscopic shavers, bone drill blanks and small powdered hard metal components.

 

This fully automated system is capable of grinding and gauging multiple components (up to 8 or more) to a high degree of precision. Configurable with pick/place gantries or six-axis robots, this machine ensures a hands-off, high production or frequent changeover operation with the assurance of automatic size compensation and 100% inspection.

 

The CNC includes integrated two-axis CNC work-wheel and regulating wheel dressers capable of dressing an 8.625-in. (219 mm) wide grinding wheel and a 10-in. (254 mm) wide regulating wheel. Another available option is the patent pending programmable work rest blade, which adjusts the lateral position of the parts (when grinding).

Features:

  • A proven technology for grinding multiple parts per cycle on a 10 or 12-in.diameter grinding wheel
  • Twin Grip Spindle is our standard design
  • Available ABEC 7 bearings and super high precision regulating wheel housing to maintain extremely tight tolerances 
  • Automatic CNC work wheel and regulating wheel dressing capability 
  • Available with a variable frequency drive on the work wheel spindle for increased wheel surface feet when running super abrasives such as vitrified CBN. Spindle RPM can be varied depending on the wheel type and wheel dressing parameters
  • High-production, lights-out grinding capability
  • Remote Connectivity using EtherCAT by and large the fastest industrial Ethernet technology.
  • This machine can also interface with Glebar Advanced Analytics, our new cloud-based solution that allows operators and managers to remotely receive actionable real-time analytics on easy-to-read dashboards; reduce downtime. boost capacity, increase your availability and more.
  • Ease of changeover and setup for short production runs
  • Super high rigidity roller guides with 0.1 micron scale feedback on the ram and ram bed & CNC work wheel dresser
  • Patent-pending controlled, motorized work rest blade slide adjusts (while grinding) lateral position of parts
  • Quick Change Gripper assembly for rapid changeover from one set of part holding grippers to a different set (i.e. 8 station to 5 station) - the entire gripper assembly is easily disconnected, lifted out of the keyed mount, and then dropped into the next mount and reconnected
  • Automatic wheel balancing and acoustic emissions system for ease of setup
  • Auto dress feature to set redress after grinding a set number of parts
  • Servo regulating wheel drive
  • 15 HP in small form factor
  • 10 to 15 minute wheel change
  • Intuititive HMI touch screen operator interface
  • Inline part diameter feedback to the control system allows the machine to correct the wheel dress profile for size variation by station
  • Available setup reduction metrology device (P4K) which scans and provides feedback of the entire component geometry for all parts in a cycle to automatically correct the grinding wheel dress shape (correcting the wheel dress shape from any measurement device is patent-pending)
  • Machine is fully serviceable in the field
  • CE certification available
  • Offline wheel dressing options to decrease downtime
