WORKPIECE AND MATERIAL
The workpiece is selected based on the finished part, and not vice versa
Seamless pipe can reduce metal removal for a range of bushings. Solid flanges, lugs and fittings may require rolling or forging. The decision depends on the dimensions, material, allowances and subsequent heat treatment.
WHAT TO CHECK
Workpiece input characteristics
The parameters are fixed before being submitted for machining.
Size
Diameter, wall, length and allowances.
Geometry
Form defects and accessible bases.
Identification
Connection between a batch of material and production.
HOW THE WORK IS CONSTRUCTED
The preparation should leave a manageable allowance
Cutting and primary processing form the workpiece for subsequent installations. The allowance takes into account thermal deformations and the amount of finishing grinding.

BEFORE AGREEMENT
The choice of workpiece determines the further route
Seamless pipe, rolled and forged pipes have different allowances and geometry restrictions. Before selecting a workpiece, the wall, length, transitions, fiber direction and batch size are checked. The decision is made based on the drawing of the part and subsequent operations, including heat treatment and grinding.
Geometry
Diameters, wall, length, flange and transition zones.
Material
Brand, delivery condition and confirmation requirements.
Allowance
Margin for machining and modification after hardening.
Party
