CNC Mold Machining for
Tool Steel &
Complex Components
In-house 3-, 4-, and 5-axis CNC machining built for hardened tool steel, deep cavities, and tight-tolerance mold components.
Engineered for Mold Components
General CNC shops focus on aluminum prototypes. At YCS, we are built for the rigorous demands of tooling. We specialize in machining hardened tool steels, deep complex cavities, and maintaining tight tolerances. By seamlessly integrating our CNC capabilities with in-house EDM, grinding, and polishing workflows, we deliver complete, ready-to-assemble mold components for OEMs and independent mold shops.
CNC Equipment & Specifications
High-rigidity machine tools equipped with high-speed spindles and advanced probing systems to ensure superior surface finish and accuracy on hardened steels.

Pre-Hardened Steels P20, 718H, NAK80
-
Hardened Steels (Up to HRC 52) H13, S136, SKD61, SKD11
-
EDM Electrodes Copper Alloys, Fine-grain Graphite
-
Specialty Materials Carbide (Evaluated per project requirements)
Size & Capacity Limits
Precision & Surface Finish
Advanced CAM & In-Process Verification
Eliminating human error through simulation and automated on-machine probing.
CAM Programming & Simulation
Utilizing UG/NX, Mastercam, PowerMILL, and HyperMILL. Every 5-axis toolpath is fully simulated to prevent collisions and optimize cutter engagement.
On-Machine Probing
Renishaw spindle probes perform automated part alignment and in-process critical dimension checks before the part leaves the machine table.
Adaptive Machining
Automated tool wear compensation and electrode spark gap adjustments ensure that the downstream EDM process is perfectly matched to the CNC output.
Multi-Axis Machining Strategies
3-Axis CNC
High-speed roughing and finishing for standard mold cavities, flat surfaces, and large mold bases.
4-Axis CNC
Rotary table integration for multi-angle cavities and cylindrical mold components, reducing setups.
5-Axis CNC
Simultaneous 5-axis for complex organic surfaces, deep cavity side walls, and undercuts in a single setup.
Uncompromising Quality & Traceability
ISO 9001 certified processes guarantee that every component matches your 3D CAD data. We provide full inspection documentation with every shipment.
