Infeed/Thrufeed Precision Centerless
Grinding Systems

The Glebar Advantage

Competing designs require a much larger footprint, with wheels so large and heavy a crane is required to change them. The compact GT-610 offers high horsepower, high rigidity and superior slide positioning. Through intelligent control and design the G-ratios (part volume removed divided by wheel volume used) can exceed machines twice its size, all while maintaining better roundness, diameter, and taper tolerances.

Introducing the GT-610

  • The highly automated GT-610 Infeed/Thrufeed Grinding System was originally designed to grind the hardest material on Earth -- diamond -- but it now also excels at grinding metal (steel, carbide, titanium etc.) and composite materials for the automotive, aerospace, medical, metal and mining industries.
  • The machine has been field tested in some of the harshest industrial environments, proving again and again its reliability and its ability to offer large capabilities, all in a small package.
  • Enclosed on a granite bed (standard platform) for reduced vibration and thermal stability. An enclosure with mist collection protecting the operator from debris and misting offering a clean and safe work environment also comes standard.
  • As with our GT-610 CNC, the GT-610 can also be put on a 5,000-pound mineral cast base designed for superior vibration dampening, rigidity and thermal properties.
Competing designs require a much larger footprint, with wheels so large and heavy a crane is required to change them.

GT-610 Highlights

Three Different Platform Options

Three Different Platform Options

1. Cast Iron Bed (no enclosure)

2. Granite Bed with Safety Enclosure (standard platform for this model)

3. 5,000 lbs. Mineral Cast Base with Enclosure

Independent Slides for Easy Setup

Independent Slides for Easy Setup

The GT-610's two independent slides (upper and lower), which control the regulating wheel and the work rest blade position, holding the part being ground in place, provide significantly easier and quicker set up than competing systems. The multi-axis controller can position both grinding wheel slides to a resolution of 0.1 micron (0.000004”).

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.

Controls and Custom Software

Controls and Custom Software

The control software is entirely developed at Glebar and is fully customizable to address your application and process. The intuitive touch screen interface allows for ease of use and flexibility. The machine software interface was developed to allow an unskilled operator to run many high precision machines simultaneously. 

Work Wheel and Regulating Wheel Dressers

Work Wheel and Regulating Wheel Dressers

The template tracing work wheel dresser incorporates single point dressing. The template tracing regulating wheel dresser allows for the dressing of shallow profiles to achieve optimal diameter and roundness accuracy.

Automation and OPC

Automation and OPC

As with other high performance Glebar machines, the GT-610 can be fitted with robots, pick-and-place gantries, cleaning and drying stations, laser inspection systems and more to provide a truly hands-off turnkey solution for high production grinding applications that demand ultimate precision. OPC interfacing to supervisory plant controls is also available to gather production data and track maintenance and critical operational statistics.

Remote Connectivity
