Glebar

Introducing the GT‐610 CNC

Building on over 65 years of twin-grip spindle design technology, Glebar is now offering an ABEC 7 twin-grip work wheel spindle design (with 12" work wheel option) on the GT-610 CNC for increased rigidity, faster component processing speed and larger diameter parts.

• 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.
• Glebar's vast experience and 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 GT-610-CNC includes integrated two-axis CNC work-wheel and regulating wheel dressers capable of dressing an 8.625-in. (219mm) wide grinding wheel and a 10" (254mm) wide regulating wheel. Another available option is our patented programmable work rest blade, which adjusts the lateral position of the parts (when grinding).

GT‐610 CNC Highlights

Rigid Mineral Cast Base

The GT-610 CNC weighs over 8,000 pounds and built on a mineral cast base for rigidity, vibration and thermal stability.

Independent Slides for Quick Setup

The GT-610 CNC'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

The machine comes standard with a 10" work wheel with super precision twin grip spindle. Glebar is now offering an ABEC 7 twin-grip work wheel spindle design (with 12" work wheel option) on the GT-610 CNC for increased rigidity, faster component processing speed and larger diameter parts.

Movable Work Rest Blade

Glebar’s patented programmable motorized work rest blade option adjusts the lateral position of the parts (when grinding), which is ideal when controlling a radius behind a fastener head or when grinding the tip of an arthroscopic shaver, for example.

CNC Work Wheel & Regulating Wheel Dressers

The CNC work wheel dresser incorporates 0.1 micron linear scales on both axis and a high-speed roll dress spindle, single point dressing also available. The CNC regulating wheel dresser allows for the dressing of complex shapes to achieve optimal diameter and roundness accuracy. 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.

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. 

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. 

Automation and OPC

As with other high performance Glebar machines, the GT-610 CNC 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

This is done by using EtherCAT® by and large the fastest industrial Ethernet technology.

P4K Compatible (Metrology Device)

The P4K serves as a setup reduction device while providing 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).
