Cam Turn & Trim

Advanced Duplex Turn & Trim System
Cam-Driven Dual-Head Machining
The OTM-4250 leverages cam-operated technology to synchronize head turning and trimming through a rigid through-hole spindle architecture, delivering consistent dimensions, superior surface finishes, and reduced errors in demanding ammo brass processing environments. Unlike traditional systems, this cam-driven turn & trim machine offers high accuracy and flexibility—perform simultaneous cuts using a single datum surface for alignment: simply swap pins and add a trim cutter to transition processes quickly. Ideal for high-volume ammunition production, it minimizes handling while maximizing output.

• Process: Simultaneous head turning and trimming in one continuous motion for efficient brass casing machining
• Outcome: Tight dimensional control, improved finish, and shorter cycle times in ammo finishing
• Control: Physical touch buttons, Allen Bradley PLC for reliable operation

Through-Hole Spindle Efficiency + Precision Alignment
Experience breakthrough efficiency with the OTM-4250’s through-hole spindle design, providing flexibility in part positioning and quick transitions between head turning and trimming to accelerate workflows in ammunition manufacturing. The single datum surface and cam-based operation ensure stable, concentric workholding across a wide caliber range, protecting brass integrity and enhancing overall productivity with repeatability within 0.004”.

• Mechanism: Through-hole spindle, cam operation, single datum surface for precision ammo processing
• Benefit: Reduced handling, faster transitions, and cleaner workflows in high-volume production
• Applications: Post-draw head profiling and length trimming for pistol, rifle, and large-caliber casings

Robust, Production-Ready Design
Engineered for the rigors of ammunition production, the OTM-4250 features heavy-duty construction for superior stability and durability, full guarding with 3/8″ polycarbonate windows, and magnetic door interlocks for operator safety. With anti-static systems, IP65 minimum and Class 1 Division 2 electrical ratings, this USA-made machine supports reliable, low-maintenance operation in challenging environments—making it the ultimate choice for cam-operated ammo equipment.

• Components: Cam-driven heads, OTM-240A case feeder, anti-static systems for durable brass machining
• Benefit: High uptime, reduced maintenance, and robust performance in ammo manufacturing settings
• Environment: Protected surfaces, sealed electronics, and safe operator access for long-term reliability
