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 an automotive 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.
The melamine fuse bodies are ground using a legacy hydraulically operated centerless form grinder. Decades of use have prompted customers to replace existing machines with newer versions.
Simplify the setup process and create a consistent operation. Ensure that the OD dimensions of the melamine fuse bodies are uniform and within the allowed tolerance.
Castle Nuts, also referred to as Castellated Nuts, are used for applications in aerospace and automotive markets where the nut cannot loosen. A cotter pin or safety wire is inserted through a cross-drilled bolt extending through the opposing slots to mechanically prevent the nut from loosening. Without the Castle Nut, the nut would separate from its shaft potentially leading to catastrophic results.
Slotting Saws, Abrasive Grinders, Wire EDM, and Sinker EDM are popular mechanical and abrasive processes used for slotting Castle Nuts. The slotting operation requires three cuts per part, cutting two slots per pass. Parts are loaded manually.
Typical saws and grinding processes require frequent wheel dressing or saw changing, dramatically reducing productivity and throughput. Current manufacturing processes can distort the slot, damage the thread, or deform the thread. Secondary deburring or re-tapping is often required after slotting. This results in increased scrap rates, increased cycle times, and reduced throughput.
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: 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 thrufeed automatically thru feed grind an automotive component and achieve a 1.2 Rz surface finish
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 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 DD-7 is one of the most compact double disc grinding machines on the market. Designed for grinding small diameter components, it accurately controls their length and perpendicularity. The machine is capable of grinding many high-performance parts for a wide range of industries from medical and aerospace to automotive. The DD-7 can be configured in three fixturing modes, depending on the application, the shape of the part, and the degree of automation required.
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-912DG Enclosed Centerless Form Grinder is designed to increase throughput, reduce setup times, and achieve tighter tolerances. Additionally, it provides better integration to gauges, automation, and remote service diagnostics. It can produce multiple cylindrical or spherical parts from a single piece of material.
The CS1-A Precision Abrasive Cutoff machine from Tridex Technology features superb accuracy and multiple bar cutting for applications requiring tight tolerances in medical, aerospace, fasteners, and automotive industries. The Precision Abrasive cut leaves almost no burr on the bar or tubing.
The SG-2060 Burr Free Electrochemical CNC Surface Grinder from Tridex Technology provides burr free and low force cutting leaving no heat affected zones while cutting. It has numerous applications across many materials and industries including medical device, automotive, and aerospace.
