Glebar's GT-610 CNC outperforms larger competing grinders, which require a much larger footprint and grinding wheels so large and heavy, a crane is required to change them. It 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.

CNC Regulating Wheel Dresser 
The GT-610 CNC weighs over 8,000 pounds and built on a mineral cast base for rigidity, vibration and thermal stability.
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”).
The machine comes standard with a 10" work wheel with super precision twin grip spindle. A 12" diameter work wheel option with cantilever spindle design -- for frequent and easy changeover is also available. Constant surface speed monitors grinding wheel circumference and adjusts spindle rotational speed to maximize grinding efficiency.
Glebar’s patent pending 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.
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.
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.
A built-in automatic wheel balancing system dynamically adjusts and eliminates wheel vibration, producing superior surface finishes and improved wheel life.
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 simplifies troubleshooting and maintenance.
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).
When a requirement exists to infeed centerless grind aerospace components in a high production environment using a high level of automation, the GT-610 CNC significantly outperforms alternative processes. Before finding Glebar, the customer had to grind one component at a time on a rebuilt Cincinnati machine. In order to meet their demand, they needed several machines with a dedicated operator on each machine. Glebar’s GT-610 CNC gives them the capability of running millions of fasteners per year (8 pieces at a time) to micron precision. The machine provides automatic size compensation by station, and the machine can run 12,000 parts before redressing the wheel on certain components. The GT-610 CNC wheel life was much greater than that of their larger Cincinnati.
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)
Designed to part specifications and integrated with machine controls. Custom feeding is available built to part specification.
Built specific to the part, Glebar offers a variety of conveyors which move parts through the process seamlessly and quickly.

An electromagnetic testing method used in nondestructive testing (NDT) making use of electromagnetic induction to detect and characterize surface and sub-surface flaws in conductive materials.
Built specific for the part, the gantry picks and places parts in the grind zone in one motion.
Diameter contact gauge mounted on exit side of the machine measures the ground part. Diameters at several points can be measured, used for size compensation, and compared against high and low user-defined limits. Contact measurement is unaffected by coolant.
Collects and removes debri and dust from the work area.
Glebar’s patent pending controlled 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, for example.
Comes with arbor, flange with four weights and stand. Balanced grinding wheels are critical for high precision parts.
A built-in automatic wheel balancing system dynamically adjusts and eliminates wheel vibration, producing superior surface finishes and improved wheel life.
Integrated acoustic emissions system for ease of setup.
Post grinding and cleaning, the data is collected, analyzed and fed back to the machine for automatic size compensation. Measurements are shown on a trend graph on the machine control.
Built specific for the part; integrated into the cell.
System engineered and developed by Glebar to separate the incoming parts and inspect each part individually at a fast rate (as fast as 2 parts-per-second in a recent case study) after exiting the vibratory bowl as a continuous row of parts.
Post grinding, system is integrated into the cell to pressure clean parts.
Both Z and X axis of feeder have velocity and position control set on the machine touch screen.
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.
Automatically picks parts from trays, loads into machine, unloads and places back to parts tray. Fully guarded and interlocked access doors. Robot arm incorporates two grippers for staging the loading and unloading during the grind cycle, reducing idle time.
Supports and facilitates the material rotation at the entry and exit sides of the grinding machine. Typically used in a thrufeed operation.

Glebar prides itself on selling precision grinding machine system solutions, tailored to your specific needs. Below is a small subset of applications, performed on this machine, that Glebar has provided solutions for over the years.
Challenge: To grind diameters on parts of many sizes and lengths for a manufacturer of aerospace fasteners. The goal was to provide a solution that gave the customer a machine with intelligence, in-process inspection, ease of use and to maximize up time and production rates.
Challenge: To grind two mating metal components, with a tight clearance requirement between their surfaces, to create a powered arthroscopic shaver used in orthopaedic joint surgeries.
Challenge: To grind a variety of tooling punches to extreme precision, while accommodating small lot sizes with short changeover times.
Challenge: Infeed grinding 0.010” on two diameters over a 7” long metal drill blank in one operation while maintaining 0.0002” diameter accuracy, .00006 roundness and maintaining part straightness and concentricity.
Challenge: To grind 2 diameters for a large manufacturer on an intricate, metal injection molded part (asthma inhaler) in high volume (millions of parts per year) to micron precision. The component needed to be precisely ground to insure critical fit in a mating portion of the device to guarantee that the device would function as intended at all times.
Challenge: To grind burnishing and expander rolls used in manufacturing tubes for a multitude of applications ranging from oil and gas tubes to automotive. Due to the shape of the parts which includes several tapers, the material removal is dramatic requiring several operations. Additionally the rolls are custom shapes so changeover between part types requires reshaping the grinding wheel.
