18CrNiMo7-6 34CrNiMo6 4140 Carbon Steel Forgings Carburizing Treatment Splicing Arc Rack

18CrNiMo7-6  34CrNiMo6 4140 carburizing Q+T treatment Splicing arc gear rack

Products:

Gear racks are utilized to convert rotating movement into linear motion. A gear rack has straight teeth cut into one surface of a square or round section of rod and operates with a pinion, which is a small cylindrical gear meshing with the gear rack.

Custom properties

Process procedure:

Forging process flow quality control:

1. Raw material steel ingot into warehouse(test the chemical content)
2. Cutting→ Heating(Furnace temperture test)
3. Heat treatment after forging(Furnace temperture test) Discharge the furnace(blank inspection)
4. Machining→ Inspection(UT,MT,Visal diamention, hardness)
5. QT→ Inspection(UT, mechanical properties, hardness, grain size)
6. Semi-Finish machining→ Inspection (dimension)
7. Carburizing quenching
8. Sand blasting
9. Finish machining
10. Painting
11. Packing and Marking(steel stamp, mark)→ Storage Shipment

Commerce clause

We can supply many types of gear racks. If the application requires a long length requiring multiple gear racks in series, we have racks with the tooth forms correctly configured at the ends. These are described as gear racks with machined ends. When a gear rack is produced, the tooth cutting process and the heat treatment process can cause it to try & go out of true. We can control this with special presses remedial& processes.
