What Tolerance Standards Do We Ensure?
We assure that our factory adheres to ISO 2768 standards for all CNC machined parts.
For parts machined with metals, we strictly follow ISO 2768-m (medium) or ISO 2768-f (fine) standards.
In the case of parts machined with plastics, we comply with 2768-m (medium) standards.
While geometric tolerances as tight as ± 0.0004 inches (0.010 mm) are attainable, it is imperative
that they are clearly specified in the technical drawings.
We can achieve even finer tolerances on shafts, with up to H7 fits, through manual quoting and,
on occasion, even tighter ones.

Specialist Industries
CNC machining is a go-to manufacturing process to get precision parts, whether for prototyping or
end-use production.
It is widely used throughout the aerospace, medical, automotive industries for its ability to rapidly
manufacture precise parts in production-grade materials, such as:
1. housings and enclosures
2. brackets
3. fixtures for manufacturing
4. gears and bearings
5. internal mechanical components
6. medical instrumentation
Company Profile
How Can I Lower the Cost of My Machined Components?
Costs associated with CNC machining can be categorized into machining time, start-up expenses,
material expenditures, and feature-related costs. To effectively reduce overall costs, it is essential
to comprehend the influence of these factors on the final expense.
1. One of the most effective means to minimize machining time is through the strategic design of
features that can be machined swiftly.
This entails making choices such as opting for appropriate radii for internal corners, reducing cavity
depth, increasing wall thicknesses, limiting thread lengths, and designing holes with standard
dimensions.
2. To curb material costs, thoughtful consideration should be given to the size of the initial blank
required and the cost-effectiveness and machinability of the base material. Softer alloys, for instance,
tend to be faster to machine.
3. Start-up costs can be mitigated by minimizing the number of part rotations or repositioning steps
needed to complete the component.
This can be achieved by dividing complex geometries into multiple parts that can be subsequently
assembled.
4. In terms of feature costs, it is prudent to employ tolerances only when absolutely necessary,
eliminate all text and lettering, and steer clear of multiple surface finishes whenever possible.
These measures collectively contribute to cost reduction in CNC machining projects.
