Custom Made CNC Milling Service CNC Machining Steel Precision Parts


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.
