CNC machining finds its best application in one-off manufacturing projects and in the
low-to-medium volume production range, spanning from several hundred to 1000 parts.
It stands out as the most economically viable option for the production of metal prototypes,
making it a preferable choice. Furthermore, CNC machining is the ideal selection when the
parts in question require exceptionally tight tolerances.
Product Details
CNC machining machines possess the versatility to cut through an extensive array of materials,
encompassing aluminum, bronze, copper, ceramics, plywood, diverse steel types, stone, wood,
zinc, and various engineering materials.
This broad range of capabilities positions CNC machining as an optimal solution for prototype
creation in product development. It facilitates the ability to make accurate and swift adjustments
until achieving satisfaction with the final product.

FAQ's
1. Can you ensure my designed component dimensions and tolerances are suitable
for production?
Rely on our team of experts to offer valuable "Design for Engineering" (DFM) support, assessing
the suitability of your designed component dimensions and tolerances for production.
We acknowledge the urgency during idea testing and strive to provide rapid turnaround on
quotes. For a comprehensive understanding of the order progression, explore our production
process page.
2. What is your typical lead time? Can my parts be produced on a rush basis?
When it comes to screw machine products, our standard lead time, which encompasses quoting,
manufacturing, and shipping, typically stands at one week. With a stellar on-time delivery rate
exceeding 99%, we prioritize timely fulfillment. In certain situations, considering factors like
tooling, gauges, and material availability, we might be equipped to produce your parts on a rush
basis. Don't hesitate to reach out and discuss your specific needs!
3. What tolerances can achieve?
Tolerance specifications are not one-size-fits-all and are influenced by factors like part size, design
geometry, the number and size of features, material properties, surface finish, and the manufacturing
process.
Upon order confirmation, a Design for Manufacturing review is conducted to pinpoint areas for potential
modification to enhance manufacturability. Clearly indicating critical tolerance areas in your design is
beneficial, allowing for adjustments to streamline production time and costs.
General tolerance guidelines are available for CNC machining in metal and plastic, plastic injection
molding, CNC metals and plastic injection molding materials, metal 3D printing (+/- 0.5mm), and an
expected shrinkage rate of +/- 0.15% for vacuum casting. It is imperative to specify all manufacturing
and technical requirements clearly in the 2D drawings for accurate adherence.
