General Case Studies

ChallengeParts are cut using abrasive cutting saws, conventional abrasive grinding, wire EDM or laser cutting; slow processes resulting in long cycle times. Potential to expose material to high heat leading to heat affected zones, recast, and slag. Requires secondary process to deburr parts and remove any surface debris which reduces productivi...

Current ProcessThe 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.ChallengesSimplify the setup process and create a consistent operation. Ensure that the OD dimensions of the melamine fuse bodie...

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.SolutionSolution: Glebar’s GT-610 Thrufeed...

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.SolutionGlebar engineers devised a series of pre- and post-grind inspection steps to e...

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...

Challenge: To thrufeed automatically thru feed grind an automotive component and achieve a 1.2 Rz surface finishSolutionUsing a GT-610 thrufeed machine coupled with a vibratory feeding system that oriented pushrod parts for thrufeed grinding, we were able to use the same automation to cover a wide range of part lengths. The pre-ground 0.098”...

Glebar Company’s position in the machine tool industry is driven by its solution orientated leadership and skilled engineering staff. Market studies have indicated a healthy growth cycle in the specialty carbide cutting tool industries especially in the aerospace sector. Glebar identified this opportunity and introduced a ne...

Challenge: To grind both sides of composite strips (fiberglass), fully automated at high speed with tight tolerances.SolutionUsing Glebar’s DD-7 Double Disc Grinder (one of the smallest on the market), the composite strip material was successfully ground from spool to spool. The machine’s tractor feed extractor and 10” grinding wheels we...

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.SolutionGlebar’s automated GT-610 CNC Infeed Centerless Grinder con...

Challenge: The customer wants to decrease cycle time while maintaining tight concentricity specifications for roughing a tungsten carbide pin.SolutionThe Glebar PG-9DOD addressed the challenge. The system was configured with dual fixtures, a six-axis robot and bowl feeder – decreasing cycle time by 50% by grinding two parts...

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.SolutionSolution: The Glebar GT-610 Infeed Centerless Grinding System addressed the challenge. As the second process to thePG-9DOD grinding operation, this ma...

Challenge: To grind a variety of tooling punches to extreme precision, while accommodating small lot sizes with short changeover times. SolutionHydraulic punch machine tooling goes through punishment when forming and stamping materials of variable thickness and hardness. The punch design is more about stringent material hardness properties, a...

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 ...

Challenge: To end grind printed circuit board carbide drill blanks used by a major tool manufacturer to qualify the blank before fluting. The existing method relied on a batch process where parts were placed, a stack at a time, into a fixture and surface ground. Control over the length was highly dependent upon the setup of eac...

Challenge: To grind felt tips for pens. Customer required a high volume turnkey solution. SolutionBefore finding Glebar, the customer was grinding these felt tips manually. Glebar sold the customer a fully automated form grinder to grind the shape from rod to felt tip, processing 8 pieces per cycle with intricate geometric shapes and radii. C...

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 SolutionGlebar’s GT-610-SD uses machine intelligence and data to predict and preempt the machine’s operational parameters. The machine is a fully...
