Our versatile 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. A 3.75” diameter fiberglass rod can be plunged down producing two 3.75” balls in 2 minutes, in comparison to alternative process where the material is turned in 10 minutes consuming a large number of turning tools in the process. Another example, 6 to 8 golf ball cores can be ground round to under 0.002” in 15 seconds. Countless consumer goods can be ground on a range of Glebar machines.
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 pastries. Also, the mating housing for the spouts must be a close fit to prevent leaking and to keep appropriate content pressure to dispense the precise amounts. Eight different components needed to be ground, all approximately four-inches in length, however they varied in diameters and weight. The variation of part geometries posed the biggest feeding challenge. Rapid changeover of grinding wheels was important to reduce setup time between the components.
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 each batch in the machine, and length adjustment and perpendicularity were cumbersome to adjust for small diameter parts. Existing machines on the market were extremely large in comparison to the small diameter of the part to be processed, and were very expensive.
The computer controlled TF-9DHD Infeed/Thrufeed Micro Grinder grinds both hard and soft materials, specializing in parts from 1” in diameter down to .002". The TF-9DHD is utilized to grind catheter, guidewires, pins, bushings, PTFE, plastics, ceramics and other engineered materials.
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 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.
