Bases
Surfaces for sequential installations.
MECHANICAL PROCESSING
CNC machining
Turning and milling of dimensions, fits and base surfaces.
Turningdiameters and ends
Millinggrooves and platforms
Holeslubrication and fixation
MECHANICAL PROCESSING
Processing bases specify the relative position of surfaces
Turning and milling operations create bore diameters, ends, grooves, holes and special features. The sequence of installations is selected taking into account the alignment and subsequent heat treatment.
WHAT TO CHECK
What is controlled in machining
Not all dimensions are brought to their final value before hardening.
Allowances
Reserve for deformation and grinding.
Coordinates
Position of holes, grooves and grooves.
Edges
Chamfers, radii and no burrs.
HOW THE WORK IS CONSTRUCTED
Roughing and finishing are separated by function
Working surfaces can be completed after heat treatment. At the same time, holes and grooves must be technologically tied to stable bases.
- DraftShape and main allowance.
- IntermediateStructural elements and control of bases.
- FinishingDimensions that do not require grinding.
RESULT
Geometry ready for next transition
The part is passed on with control of the required dimensions and a preserved allowance for finishing.
- BaseStable orientation.
- elementGrooves and holes.
- AllowanceReserve for the finish.
BEFORE AGREEMENT
Bases and control zones are determined before processing
Turning and milling operations are built around the functional surfaces of a part. The drawing must have legible bases, relative position tolerances, holes, grooves and areas of subsequent processing. Allowances are consistent with heat treating and finishing sanding to avoid judging each operation separately.
Basing
Surfaces that define the alignment, length and position of elements.
Transitions
Chamfers, radii, grooves, holes and unmachined areas.
Allowances
Material for hardening and subsequent finishing.
Check
Intermediate and final dimensions along the route.
