Aeromet "Stick and Run" Reversing Mill Mandrel for the Steel Producing Industry

01. Challenge

A steel producing industry client charged Aeromet with the task of designing and manufacturing a mandrel drum that was capable of tremendous gripping power, yet had a simplistic design for ease of maintenance and longevity.

02. Approach

Aeromet’s experienced engineers worked with the customer to determine their requirements, and designed and manufactured the "stick and run" mandrel. To machine this part, we used a CNC Ryazan lathe, CNC Union floor bar mill, CNC Giddings and Lewis bar mill. Made from 4340 steel HT to 160,000 yield and 4140 steel, the mandrel was CNC machined to 24" x 234", weighed 22,000 lbs. and met tolerances of ±.002". We applied chrome plating and ion nitriding with a turned or milled finish.

03. Results

After extensive inspection of the components during the production process and full testing of the mandrel once it was completed, our machining process met ISO 9001:2015 standards and fulfilled all of the client’s requirements.
