CNC MILLING OF HELICAL GEAR RACKS

At Industrial Sprockets & Gears, Inc., we are capable of manufacturing complex gears and sprockets that no other manufacturers can produce. The part shown here is a helical gear rack that is used on a Maag gear manufacturing machine. The gear rack is 6′ long, has a nominal cross-section of 3” by 2”, and is constructed of 4130 steel.

The customer needed a replacement part which is necessary to the operation of their machine and had previously been unable to find someone with the capacity to cut the required size of helical rack. Many times customers contact us because OEM parts are no longer available or are cost prohibitive. Often, customers have found that the quality of replacement parts produced by us exceed the quality their OEM parts.

Many of our projects are unique within the industry and represent some of the most challenging sizes and geometries of gears produced today. We maintain a wide range of rare gear shaping equipment as well as advanced CNC milling and turning centers, which allows us to produce a vast array of gear, sprocket, work, and rack sizes, shapes, and patterns.

The rack was manufactured on a specialized CNC gear rack milling machine to tolerances as tight as ±0.001″. The dimensions were verified using the measurement over wire method to AGMA Class 8 standards. The customer was not only pleased to find a manufacturer capable of producing the part; they remarked that the quality far exceeded their expectations. We produced this helical gear rack with a lead time of only two weeks. For additional information about this custom gear rack machining project, contact us directly.
