CNC Machining of an Aluminum Safety Coupling

CNC Machining of an Aluminum Safety Coupling

A customer in the valve industry approached Hogge Precision to manufacture an aluminum safety coupling. The customer has previously purchased a machined blank from China and brought it in-house to perform the cross drilling and O.D. finishing requirements.

Safety couplings are designed to slip or disengage when a pre-determined torque limit is reached. All safety couplings serve as an absolute emergency stop for safe and reliable disengagement between drive and loads.

Unsatisfied with previous manufacturing, the customer came to us. We took on the project and performed CNC turning and CNC milling using a twin turret twin spindle turning center running lights out. The finished product, made of 7075 aluminum, measured 2.425 inches in length and the O.D. was .875 inches. We performed full testing and inspections on the product before shipping.

The client was highly pleased with the outcome, and now purchases 5,000 units of the product per month.

Hogge Precision is an ISO 9001:2015-certified contract manufacturer of precision-machined components.

Project Specs

With our skilled technicians and advanced equipment, we can meet specific tolerances and specifications to manufacture the best solution for our customers. Below are some of the spec highlights and equipment details from this project:

  • The tightest tolerances that can be met are within ±.001″
  • The component was manufactured using 7075 aluminum, a primary alloying element that exhibits good ductility and high strength
  • The primary piece of equipment used was a twin turret – twin spindle turning center with automatic raw material & parts handling
  • The overall part dimensions included an outside diameter of Ø.875″ and a length of 2.425″. These dimensions were easily replicated and can be produced through lights our manufacturing through our automation capabilities.
