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, with exceptional precision. Glebar engineers can tailor an Metals Precision Grinding Solution which can offer the customer a machine with intelligence, in-process inspection, ease of use, and mulitple part-per-cycle capability -- maximizing up time and production rates.
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.
To establish a process whereby pre-sintered carbide drill blanks processed in a hot isostatic press (HIP) can be pre-sized to produce straight rod stock for long blanks. The existing method of manufacture involves sintering the carbide rods in a hot isostatic press then grinding them to size in a hard state before the fluting operation is performed. This procedure requires multiple thrufeed grinding operations which is labor intensive and accelerates wear and tear to the grinding machine and tooling since the hard carbide usually has a non-uniform lumpy surface; furthermore several thrufeed passes are need post-sintering to size the carbide to its final diameter and to achieve the uniform diameter required.
Challenge: Customer wants to decrease cycle time by taking this from a one-sided traditional surface grinding application requiring two operations to a single double end grinding application.
Challenge: The customer wants to decrease cycle time while maintaining tight concentricity specifications for roughing a tungsten carbide pin.
Challenge: Satisfying the high volume finishing requirements for the complex form geometry on a hard carbide pin application. This compliments the PG-9DOD Carbide Pin Roughing Operation.
Challenge: To grind a variety of tooling punches to extreme precision, while accommodating small lot sizes with short changeover 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.
Challenge: Quality, cost control and lead time issues of outsourcing the pre-sizing of titanium and steel bars
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.
