Description
High-performance Doringer D350-SA Semi-Automatic Circular Cold Sawing Machine, engineered for precision repetitious cutting of solids, pipe, and wide sectionals.

Doringer cold saws are the industry benchmark for burr-free metal cutting. This semi-automatic model features a hydro-pneumatically controlled downfeed unit with adjustable rapid movement and return. The cutting cycle is entirely controlled via a bellows hydrocheck for consistent production. For maximum safety, the motor automatically shuts off when the head is in the upper rest position, and the system is designed to stay inactive if electrical power is disconnected.

Heavy-Duty Motor & Gearbox Performance
Driven by a 3 HP AC constant torque motor, this unit offers two speed ranges to suit your material needs. The Motor Type "A" configuration provides 1700/3400 RPM (54/108 sawblade RPM) for mild steel and non-ferrous materials. The Motor Type "B" configuration provides 850/1700 RPM (27/54 sawblade RPM) specifically for alloys and stainless steel. All power is delivered through a precision 1:31 reduction ratio for maximum torque.

Precision Construction & Clamping
The D350-SA features a turn table constructed of Class 40 cast iron—machined to tolerances within ±0.001". The clamping unit utilizes two separate air cylinders, each individually adjustable for depth and pressure, providing a total of 8,000 pounds of clamping power. Each cylinder can be moved left or right to allow the blade to finish the cut completely while maintaining a safe 0.250" forward stroke movement.

Fair Sell Price Analysis
Current Asking Price: $18,850.00

Market Context: The Doringer D350-SA is a premium, American-engineered asset. With its 8,000 lb clamping force and semi-automatic cycle, it significantly outperforms standard manual cold saws. Newly factory refurbished units represent a top-tier investment. On the secondary market, these units command high value due to their "lifetime" build quality and "Made in USA" support.

Fair Price: $18,850.

Rationale: At $18,850, this price reflects the machine's industrial capabilities and high-grade construction. Given the 12-month manufacturer warranty on materials and the machine's ability to eliminate secondary finishing through burr-free cuts, this represents a solid ROI for any precision fabrication facility.
