Specifiable Dimensional Tolerances

  • When uploading 3D CAD data, you can specify any dimensional tolerances for parts where dimensions and tolerances are not displayed.
  • The minimum specifiable tolerance range for tolerances depends on the combination of the part shape.
  • Depending on other settings, in-range precision may not be covered by the service.

Fit Tolerances

The fit tolerances that can be set for turning machining and secondary machining are as follows.

Type of MachiningFit Tolerances
turningMetal: Grade IT6 or above
Resin：：Grade IT7 or above
  • MC
  • (Secondary Machining)
Metal: Grade IT7 or above
Resin：：Grade IT7 or above

Caution

  • “The following surface treatments cannot be specified with a tolerance range of less than 0.1.”

Tip

    • (1) Holes on the same circumference are called P.C.D. (Pitch Circle Diameter). Cross bores are not supported.
    • (2) P.C.D is recognized even with different hole types.
    • (3) P.C.D. is recognised regardless of whether the positions of the holes are equally or unequally divided. ​
    • (4) It is possible to add diagonal dimensions that indicate the distance between the holes and the P.C.D.
P.C.D. Equally divided P.C.D. Unequally divided The distance between P.C.D. holes.

Caution

  • The P.C.D. recognition is an additional and reference information in meviy for turning parts.
  • If you need to specify the tolerance between holes, please select the “Add tolerance” icon and specify the tolerance for the target position.

Tip

  • The positional relationship of holes on both end faces of the reference model in the figure below is a general tolerance.

Notes

  • 3D Model Color Schemes
  • If a colour scheme for an unsupported shape is displayed, automatic quotation is not available.

Geometric Tolerance

Possible geometric tolerance setting conditions are as follows.
configurable plane
  • Holes, keyways (inner diameter/outer diameter), notches (including pockets), inner diameter grooves, and end grooves cannot be specified.
  • If a datum or geometric tolerance is specified for the threaded part, we guarantee it based on the measured value before threading.
Configurable geometric tolerances
*Depending on the material and size, the estimate may be provided by the person in charge.
