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

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: Customer wants to increase output for steel taps used to drill threaded holes as used in the machining and tooling industry. In addition to speeding up the throughput time, achieving the exact tolerances is critical for the component to create the proper threads.
Challenge: The customer is looking for a turnkey, one operation automated process allowing a single pass solution for Stainless Steel Bone Pins, for example.
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.
Asthma inhalers are comprised of a medicine canister fitting inside a plastic sleeve. When the patient pushes the canister, the stem, a small metal pin, releases an actuator inside the sleeve allowing the medication to be released and inhaled by the patient. The stem must mate properly with the actuator to ensure the medication is dispersed properly. Any defect could cause the device to fail.
Current Process & Challenges: Slow Production, High Labor and Integration Costs
Asthma inhaler pins are ground one at a time using multiple production lines and automation integrations. This setup requires a large footprint to meet high demand. Labor and numerous automation integration costs are expensive.
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.
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.
