Our versatile precision grinding machines are workhorses which require a smaller footprint than similar machines yet excel in demanding high production environments where the name of the game is high volume at low cost. Glebar engineers can tailor a mining and/or energy precision grinding turnkey solution, complete with a series of pre- and post-grind inspection steps, ensuring the product going into the Glebar machine meets the requirements of the final ground product with guaranteed accuracy.
Current Process
Zirconium tubes are cut one at a time using carbide tools on a lathe. A lathe cutoff leaves burrs requiring deburring to achieve a smooth surface finish. Carbide tooling wears quickly when cutting zirconium and is expensive.
Challenges
Deliver a cost-effective process to cut zirconium tubes which reduces the number of steps in production. Zirconium is highly flammable, and a dull carbide tool can cause the material to overheat and catch fire. Zirconium fires are dangerous and very hard to extinguish.
Challenge: To grind a ceramic insulator body for lean burn gas engines for use in cogeneration plants and containerized power generation units. Customer required four diameters as well multiple compound angles and radii to be ground concentric to the ID within .003”.
Challenge: To process carbide and polycrystalline diamond with complete automation, conserving grinding wheels and using little power, all on a machine within a small footprint
Challenge: To accurately grind alumina spacers used in nuclear power plant control rods. The length of the components are extremely critical to the efficiency of the fuel rod. The components need to be processed at a high rate and length verified for all parts.
Found at the highest end of the GT‐610 series spectrum, the GT‐610 CNC High Precision Automated Infeed/Thrufeed Centerless Grinding Machine excels at grinding a wide range of materials and is the complete "lights‐out" solution for applications where a high degree of automation, data gathering and gauging feedback is required. In addition to our 10" work wheel design, 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 Automated Infeed/Thrufeed Centerless Grinding Machine can be custom fitted with automation. This system is the ideal option for when infeed applications do not require a CNC dresser and for the vast majority of thrufeed applications. The GT-610 excels at hard metals and composites, producing carbide blanks, spools, bushings, and engine components such as automotive fasteners and valve lifters. It can also effectively size down metal bars.
The GT-610-SD is a highly automated infeed/thrufeed multiple pass machine with a cleaning station, inline gauging and automatic size compensation, designed for use on hard materials. This machine is ideal when a high degree of data gathering is required along with a desire to limit consumable usage. Applications include PCD drill bits and hard carbide components for drilling industries. It is available with enclosure (as shown).
The GT-610 EZ is the newest addition to the GT Series Centerless Grinder suite. A lean version of the GT-610, the GT-610 EZ brings slide motion control to the operator at an affordable price point. Operating on a much smaller footprint than the competition, this system excels at thrufeed grinding hard materials such as steel, carbide, pcd inserts and technical ceramics. Slide positioning allows for precise diameter control on close-tolerance components. The machine is also capable of gauge feedback for even more precise diameter control.
The GT-610M is an affordable, compact, precision thrufeed grinding system, built for the machine shop. Applications include spool valves, bar stock, pins, bushings, metals, hard and green ceramics, and other engineered materials.
The P4K Gauging System is the fastest and most accurate profile metrology system available for long parts or multiple short parts and is the gold standard quality control device for the measurement of guidewires. As a setup reduction device (for the GT-610 CNC), the P4K 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).This is done in a matter of seconds, drastically reducing setup time and improving quality control. For other compatible Glebar machines, (GT-610, GT-610 SD, CAM.2 and GT-9AC) the P4K serves as a closed-loop quality control device that feeds back diameter to the control system for automatic size compensation. From titanium fasteners to medical guidewires, the P4K system has you covered.
The PG-9X20DHD form grinding machine was developed to size pre-sintered carbide rods in the pre-fired state. Additional applications include crystal quartz glass boules used to make fiber optics.
The PG-9DHD Centerless Form Grinder produces multiple parts from a single piece of material, in addition to grinding pre-formed parts to finished shape with extreme precision. Examples of applications are carbon fiber components, fuse bodies, golf balls, drumsticks, felt pen nibs, check valves for pumps and valves, and insulators for electronic components.
The FW-9D Ferris Wheel / OD machine forms parts concentric to the inner diameter. Typical applications of the FW-9D are car oxygen sensors, spark plugs, rubber feed rollers, and ceramic insulators.
The PG-9BHD is a hydraulically-driven centerless Form grinding machine designed to form multiple components from rod or preformed parts. Examples of parts ground on this machine include carbon fiber and Teflon® (PTFE) components, golf balls, check valves, drumsticks, deodorant balls, pen nibs, ceramic balls, rubber balls, billiard balls, and more.
