Introducing the GT-610 SD

  • Designed to grind supermaterials such as polycrystalline diamonds, the GT-610SD platform can be adapted to solve other hard materials where the process is unknown and challenging.
  • This machine was configured to gather all the parameters affecting the grinding process for the sake of analysis and optimization. The result is the ability to fine tune the grinding process through data acquisition and then modify it to improve throughput, increase wheel life, and achieve the most optimum setup.
  • The GT-610 SD is built on a mineral cast base for thermal and vibration stability and it is powered by a 15HP spindle motor driving a high precision spindle assembly on the work wheel side.
With a 10" x 8.25" work wheel, one would assume the machine is too small to optimally grind the hardest material on earth. However, Glebar's Intelligent Motion Control software, adapts the cycle to in-process, measured grinding pressures.

GT-610 SD Highlights

Machine Bed

Machine Bed

Like the GT-610 CNC, the GT-610 SD weighs approximately 8,000 pounds and is built on a mineral cast base for rigidity, thermal and vibration stability. 

Independent Slides and Multi-axis Precision Control

Independent Slides and Multi-axis Precision Control

The super high rigidity roller guides carry the work rest blade on one axis and the regulating wheel on an independent second axis. Both are precision ground surfaces and maintain a resolution of 0.1 microns. The high-speed, high-performance multi-axis controller ensures that diameter control is maintained.

Workhead Assembly

Workhead Assembly

A 15HP motor drives the 10" (254 mm) diameter x 8-5/8" (219 mm) wide grinding wheel mounted on a twin-grip super precision spindle. With a variable speed vector drive, the machine maintains constant surface speed as the work wheel wears, ensuring repeatable and efficient grinding performance. The workhead assembly design allows a single operator to replace the grinding wheel in under 15 minutes.

Work Wheel Dresser

Work Wheel Dresser

The machine control detects loading on the grinding wheel and initiates the dressing cycle to maintain efficient grinding.

Controls and Custom Software

Controls and Custom Software

Where this machine shines is in the control software, which is entirely developed at Glebar and customizable to address your application and your process. The intuitive touch screen interface allows all movable axes of the machine and peripherals to be programmed for an efficient, short cycle.The controller can also interface with a gantry system for efficiency. A laser micrometer can also be integrated to directly feedback part diameters for automatic size compensation.

Automatic Wheel Balancing System

Automatic Wheel Balancing System

A built-in automatic wheel balancing system dynamically adjusts and eliminates wheel vibration, producing superior surface finishes and improved wheel life. 

Six-Axis Robot Automation

Six-Axis Robot Automation

To provide a completely hands-off system, this machine incorporates a 6-axis robot, which picks a part from a pallet, places it in a high accuracy optical gauge, measures the component in three places, and then the machine determines what to do next to reach its target diameter. It then proceeds to grind, clean and dry the part. OPC interfacing to supervisory plant controls is also available to gather production data and track maintenance and critical operational statistics.

Remote Connectivity

Remote Connectivity

Remote connectivity simplifies troubleshooting and maintenance.
