CNC Machining
Joincast operates 49 CNC machining systems, including 14 OKUMA horizontal lathes, 33 FANUC vertical machining centers, and two vertical machining centers. All all of our machines are equipped with 4th-axis capability to handle complex geometries. We also have automated loading and unloading systems to support efficient high-volume production.
Our CNC facility is fully temperature controlled to maintain dimensional stability throughout machining operations. This is vital when you are targeting consistent ±0.01 mm accuracy (H6–H7 tolerances).
We perform n-line quality inspection at every stage of the machining process. CMM sampling and 3D scanning are carried out at defined intervals to confirm geometrical accuracy, so that we can identify and correct any deviation immediately before parts move on to surface treatment or final inspection.

CNC Machining FAQ
Can you machine features that cannot be die cast, like internal threads or tight-tolerance bores?
Yes, our 49 CNC machines handle secondary operations including threading, precision boring, tapping, and chamfering that cannot be achieved in the casting process.
All machining centers have 4th axis capability for complex angled features, and our OKUMA horizontal lathes are specifically configured for precision bore work on valve bodies and cylindrical components.
What tolerances should I specify for as-cast surfaces versus CNC machined surfaces?
As-cast surfaces typically hold ±0.1mm, while our CNC machined surfaces achieve ±0.01mm (H6-H7 tolerances) in our temperature-controlled facility.
We recommend specifying tighter tolerances only on critical mating surfaces and functional features to optimize cost, as excessive machining removes the economic advantage of die casting’s near-net-shape capability.
Do you require customers to provide CNC fixtures, or are they included in tooling costs?
Our fixture design and fabrication team develops all CNC fixtures in-house as part of the project setup. Fixture costs are separate from die casting mold costs but are included in the initial quotation.
We maintain all fixtures at our Changhua facility for the life of your project, ensuring consistent setup for repeat orders.
How do you prevent dimensional drift during high-volume CNC production runs?
Our quality team performs CMM sampling at defined intervals throughout production runs, with automatic process adjustment if measurements trend toward tolerance limits.
Temperature-controlled machining prevents thermal expansion issues, and our ISO 9001:2015 system requires statistical process control documentation for all high-volume orders to ensure consistency from first part to last.
Can you handle secondary operations like deburring, tapping, and countersinking in-house?
Yes, all secondary operations are performed within our facility. Our 8 polishing machines and 3 shot blasting systems handle deburring after casting, while tapping, countersinking, and chamfering are programmed into CNC operations.
This eliminates the quality control gaps and lead time delays that occur when these operations are outsourced to third-party machine shops.
What CNC machining capabilities do you have for large castings from your 900T die casting machine?
Our 2 Victor Taichung vertical machining centers accommodate parts up to 1300 x 600 x 610 mm with ±0.01mm accuracy. These machines have reinforced beds and temperature monitoring specifically for large aluminum castings, preventing deflection during heavy cuts.
Large parts receive additional CMM verification points to ensure dimensional accuracy across the entire casting surface.
