Eliminating HVAC Production Bottlenecks

Refrigeration components demand absolute geometric precision to prevent gas leaks, often requiring secondary honing or burnishing operations that kill production speed. APEX SPM designs dedicated automated machines that execute boring, tapping, and honing simultaneously in a single continuous cycle, slashing your cost-per-part while guaranteeing airtight quality.

🗜️

Single-Setup Clamping

Complex multi-port AC valves are machined from 3 or 4 directions simultaneously without ever un-clamping the part, ensuring perfect concentricity.

Integrated Honing

For compressor cylinders, our rotary transfer machines can feature built-in honing stations to achieve mirror-like internal finishes (Ra 0.4) inline.

⏱️

Massive Volume (UPH)

Drop cycle times from minutes down to 5–10 seconds per piece. Fully compatible with automated vibratory bowl feeders for unattended runs.

Frequently Asked Questions

How do APEX machines prevent refrigerant leakage in valves?

Refrigerant leaks are usually caused by poor surface finishes or concentricity misalignment between ports. Our Rotary Transfer SPMs process all internal bores and sealing surfaces simultaneously in a single clamping setup. This eliminates the re-fixturing errors common in standard CNC lathes and easily achieves Ra 0.8-1.6 finishes for hermetic sealing.

Can your machines handle both brass and cast iron compressor parts?

Yes. Our machines are built on rigid, vibration-dampening cast iron beds. We configure spindle speeds, coolant delivery systems, and tool holders specifically for the material you process—whether it’s high-speed cutting for forged CW617N brass valves or heavy-duty boring for cast iron compressor cylinders.

Can you integrate automatic honing for compressor cylinders?

Absolutely. For compressor cylinder machining lines, we integrate specialized precision honing stations directly into the Rotary Transfer dial, allowing you to achieve the final required micro-finish without moving the part to a separate honing machine.
