Our precision centerless grinding machines are used to manufacture bone pins, anchors, arthroscopic shavers and numerous other implants and instruments required in the surgical repair of sports injuries such as joint repairs, bone fractures, and torn soft tissue. Our centerless grinders consume minimal footprint in your factory and deliver precision product at high volumes and low cost.
Our versatile precision centerless grinders 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 turnkey a precision centerless grinder, complete with a series of pre- and post-grind inspection steps, ensuring the product going into the Glebar grinder meets the requirements of the final ground product with guaranteed accuracy.
The arthroscopic shaver teeth are commonly produced by conventional abrasive grinding, wire EDM, or laser cutting; slow processes resulting in long cycle times. EDM and laser cutting burn away the metal at high temperatures leaving changes to the metal surface including a heat affected zone, recast, and slag. Laser cutting requires significant post processing to produce an acceptable sharp edge and surface finish. Conventional grinding requires a secondary process of deburring without damaging the cutting edge. It also involves frequent wheel dressing to maintain the correct form.
Design a process that can cut shaver teeth burr free, without recast, slag, or heat damage that improves cycle times.
Tubes are cut one at a time using a standard abrasive cutting saw which leaves burrs. Requires secondary process of wire brushing and tumbling to deburr tubes and remove any debris. Older machines have poor accuracy and outdated safety features. Debris from abrasive cuts cause frequent maintenance issues.
Design a process that can cut multiple tubes burr free simultaneously without damage from debris. Reduce the number of steps in the production process. Provide a machine that won’t deteriorate over time.
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.
The customer was outsourcing grinding of components and came to Glebar looking for a way to reduce lead times on parts, reduce costs, and bring grinding capability in-house.
Original challenge was to thrufeed 1-½” diameter, 15’ aluminum tubes removing 0.003”-0.006” per pass. The second requirement was for the machine to be capable of grinding 8’ steel tubes which featured a 1” diameter bearing surface in the middle of the tube which could not be ground. This meant that the grind would have to begin in the middle of the tube where the machine had to infeed into that section and then initiate a thrufeed process. The part also had a thin wall that had to be maintained and the grinding process had to be controlled to avoid burning.
Challenge: To grind diameters on parts of many sizes and lengths for a manufacturer of aerospace fasteners. The goal was to provide a solution that gave the customer a machine with intelligence, in-process inspection, ease of use and to maximize 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.
Manufacturers use lapping machines which are unable to hold consistent tolerances or capacity, creating inconsistent surface finishes and longer cycle times.
Provide a form grinding solution for 1" and 1.4" deodorant balls while meeting the customer's cycle time and surface finish requirements.
A top tier technical ceramics OEM in the consumer goods industry required a precision grinding solution for their ceramic shaft components. They needed an automated turnkey process that could integrate with the company’s existing ceramic press to accurately grind and handle multiple-parts per cycle and do so in a way that will ensure the parts do not chip or break due to the brittle consistency of pre-sintered ceramics.
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.
Challenge: Lack of a clear, simple method to inspect the geometric profile of many components, including titanium aerospace fasteners. Existing systems are slow, unreliable, and complex to operate.
