This integrated and coordinated development of thermoforming machines and tools is our most important customer benefit and unique on the thermoforming market. With the comprehensive know-how of our experienced experts in both tool and machine engineering, our clients benefit from a unique synergy effect that leads to a higher service life of both machine and tools, and also an optimal formed component quality. We try to surpass your goals and make sure your success with this quality.
For a long time, a machine tool builder had manufactured their own precision gear racks to achieve ultra-precise positioning on their machines. They also required this because their vital clients demanded that their machines maintain accurate positioning without any error compensation on the axis.
To save costs, they wanted to find a gear rack supplier who could accomplish the same tight rack tolerances and performance level that they had come gear rack for Machine Tool Industry accustom to.
Choosing from their wide selection of regular rack & pinion drives, ATLANTA offered a Ultra-High Precision DIN 4 (UHPR) gear rack, which got a total pitch deviation of significantly less than twelve microns (< 0.012 mm) over a one meter length. The real pitch deviation was measured at 20º C and marked on each rack. To attain the high rack strength the customer required, the main of the teeth were hardened together with the tooth flanks. Finally, precision grinding was used to achieve the needed flatness tolerances on the trunk and sides of the rack.
At Industrial Sprockets & Gears, Inc., we are capable of manufacturing complicated gears and sprockets that no additional manufacturers can produce. The part shown here is a helical gear rack that is utilized on a Maag gear manufacturing machine. The apparatus rack is 6′ long, includes a nominal cross-section of 3” by 2”, and is constructed of 4130 steel.
The customer needed a replacement part which is essential to the procedure of their machine and had previously been unable to find someone with the capability to slice the required size of helical rack. Many times customers e mail us because OEM parts are no longer available or are price prohibitive. Often, clients have found that the quality of replacement parts made by us exceed the quality their OEM parts.
Quite a few projects are unique within the industry and represent one of the most challenging sizes and geometries of gears produced today. We maintain a wide selection of rare gear shaping tools as well as advanced CNC milling and turning centers, which allows us to produce a vast array of gear, sprocket, work, and rack sizes, forms, and patterns.
The rack was manufactured on a specialized CNC gear rack milling machine to tolerances as tight as ±0.001″. The client was not only very happy to find a producer with the capacity of producing the part; they remarked that the quality far exceeded their objectives. We created this helical gear rack with a business lead time of only two weeks. For additional details about this custom gear rack machining project, contact us directly.
A rack and pinion drive program includes a rack (or a “linear equipment”) and a pinion (or “circular gear”). The teeth of a rack and pinion drive could be directly or helical, although helical teeth are often used because of their higher load capacity and quieter operation. For a rack and pinion drive system, the maximum force that can be transmitted is largely dependant on the tooth pitch and the size of the pinion.
