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.

2. Granite Bed with Safety Enclosure (standard platform for this model)
3. 5,000 lbs. Mineral Cast Base with Enclosure
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”).
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.
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.
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.
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 simplifies troubleshooting and maintenance.
The P4K serves as a closed-loop quality control device that feeds back diameter to the control system for automatic size compensation.
Available metrology device (P4K) which can serve as a closed-loop quality control device that feeds back diameter to the control system for automatic size compensation
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.
Uses a formed template to dress shallow shapes into the grinding wheel. An auto dress version of this dresser available.
Uses a formed template to dress shallow shapes into the regulating wheel.
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.
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.
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.
30 gallon capacity with two removable settling tanks centrifugal pump & filtration package
Integrates into cell, built specific for the part.
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: A food equipment manufacturer approached Glebar to improve productivity and reduce costs for their food filler machines. The metal spout requires grinding for several reasons. They come in contact with food, therefore requiring a smooth finish for sanitary purposes. The tubes are often exchanged on the machines to dispense various size pastries. Also, the mating housing for the spouts must be a close fit to prevent leaking and to keep appropriate content pressure to dispense the precise amounts. Eight different components needed to be ground, all approximately four-inches in length, however they varied in diameters and weight. The variation of part geometries posed the biggest feeding challenge. Rapid changeover of grinding wheels was important to reduce setup time between the components.
Challenge: A tier one automotive fastener supplier needed to grind bolts for a major automotive company automatically at high volume, with a high degree of precision.The customer’s existing process was outsourced and was running one part at a time, resulting in a higher cost for our customer.In addition, quality and consistency of the components post grind was an issue.
Challenge: To devise a new process for an automotive component manufacturer to automatically grind and gauge pinion shafts for differentials. The shafts are made of hardened steel. The Customer is looking to expand their automotive manufacturing portfolio by bringing large volume production in-house.
Challenge: To design a fully automated turnkey feeding and inspection solution, integrated into to a Glebar GT-610 Thrufeed Grinder that ensures a one hundred percent defect-free product that is ground to a minimum 1.7 CpK and packaged hands-free.
Challenge: To auto thrufeed grind metal valve seat components which are used in the automotive industry. The customer needed a system which could accurately grind and gauge 3,000 parts per hour. The width and nonsymmetrical geometry, would be the most difficult challenge engineers would face in devising a successful staging and feeding process as they are not able to line and stack up onto a traditional conveyor without falling over.
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 thrufeed grind composite pellets, consisting of uranium oxide, which are used to manufacture radiopharmaceuticals used in CT scans. The pellet count had to be tracked through the machine and the customer needed to measure a set frequency of parts that would be programmable. In addition to accounting for all the components, the machine had to separate the set number of parts processed for data collection.
Challenge: To size thin walled tubing used for surgical instruments insuring a mirror like 3Ra finish.
Challenge: Quality, cost control and lead time issues of outsourcing the pre-sizing of titanium and steel bars
Challenge: To thrufeed automatically thru feed grind an automotive component and achieve a 1.2 Rz surface finish
