HEADING MACHINES
High-precision multi-station cold heading presses engineered for maximum stroke accuracy, long tool life, and versatile component production.
Key Technical Advantages
Explore the structural innovations behind CEVA high-speed heading presses.
Aluminum-Bronze Slide Precision
Precision is guaranteed by the dimensions of the lateral and support slides, built in aluminum-bronze, which allow proper tolerances between the sliding surfaces.
Conjugated Cam Transfer System
The movement of the Transfer is realized through conjugated cams studied for smooth movements, especially during the phase of introduction of the pieces in the dies.
Large Head Conformation
The opening of the fingers allows the extraction of the dies without the need to lift the transfer, thus allowing the conformation of large diameter heads.
Low Speed Stainless Steel Forging
Due to its design, even at reduced speeds, the press is able to forge parts with high precision. This is an advantage when forging parts that are difficult to transport or made of stainless steel.
1/4 Reduction Flywheel Drive vs Conventional Designs
Another major advantage is that the flywheel is not mounted directly on the crankshaft (as in conventional Chinese designs) but on an independent reduction shaft.
Key Benefit: This 1/4 reduction allows the flywheel 4 full turns to recover energy used during pressing, outperforming designs where the flywheel must recover turn-after-turn.
Custom Cycle Timing
Varying the operational times allows the machine to produce extremely difficult and unique geometry parts that could not be manufactured with ordinary machines.
High Pressure Continuous Lubrication
Continuous lubrication at high pressure (60-80 bar) ensures a constant oil film on moving parts (connecting rod bushing, lateral/vertical slides) to maximize durability and press accuracy.
Flexible Length & Pneumatic Trimming
Minimum length under the head is restricted only by cut-off length. Pneumatic trimming occurs in the final two stations with front or rear extraction shaft pushes based on customer specs.
Dual Gear Motors & Straight Cut-off
Top gear motor regulates wire blank cutting length, while a second gear motor allows fine tool adjustment without running the main motor (significantly reducing energy consumption).
Standardized Commercial Components & Ergonomic Maintenance
Commercial parts are widely utilized across the design, resulting in lower total cost of ownership and fast global availability for spare parts. Maintenance is intuitive and ergonomic: all critical moving assemblies are positioned externally to the main machine frame for easy access.
