If a drawing or specification
sheet has not been provided by the custome
r, a company may provide general specifications to follow to manufacture a model. These specifications may change from one company to another. In addition, some companies do not have default tolerances and will require the customer to provide the specifications.
Listed below are the specifications Xometry follows when a customer has not provided any.
Tolerance for all dimensions will be ¡À.005 in. for all metal parts and ¡À.010 in. for all plastic parts.
The finish will be an as milled finish to a maximum 125 microinches RMS.
If tapped holes are not added on the quote and a provided drawing, they will not be added to the part and will be machined to the diameter specified in the model.
No surface treatment (bead blast, anodize, powder coat, etc.) will be applied unless specifically requested by the customer.
For metal parts, walls should be a minimum 0.030 in. (~0.75 mm) thick.
For plastic parts, walls should be a minimum of 0.060 in. (~1.5 mm) thick.
When the customer doesn¡¯t supply specifications, Xometry follows its own set of specs.
These are the reasons and treatment methods for the general tolerance in the production and processing process.
