Technical Evaluation of the FEINTOOL HFA 8000
Hydraulic Fineblanking Press (Nominal 800T, Retrofit Year 2018)
1. Technical Evaluation Overview
The FEINTOOL HFA 8000 is a hydraulic fineblanking press originally rated at 630 tons and retrofitted by FEINTOOL in 2018 to an 800-ton configuration. The press provides a total force range of 50–800 tons, with dedicated forces for fineblanking processes, including vee-ring force (40–400 tons), back pressure force (20–200 tons), stripping force (130 tons), and ejection force up to 65 tons.
Stroke capabilities include a slide stroke of 30–200 mm, vee-ring stroke of 40 mm, and back pressure stroke of 40 mm, supporting controlled fineblanking cycles. Speed ranges are specified for each phase: rapid approach up to 120 mm/s, blanking speed of 5–50 mm/s, and return speed up to 135 mm/s.
Die clamping areas are listed as 1000 × 1000 mm (top) and 1010 × 1600 mm (bottom), defining the tooling envelope. The press requires 160 kW of installed power. An integrated uncoiling line is included, featuring 5 rollers, strip widths from 50–450 mm, maximum strip thickness of 10 mm, and a hydraulic straightener with strip lifter.
2. What to Check Before Buying
Given the retrofit history, verification should focus on the scope and documentation of the 2018 FEINTOOL retrofit, including hydraulic upgrades, structural reinforcements (if any), control modifications, and safety compliance.
Hydraulically, pressure stability and response should be tested across all force circuits (main press, vee-ring, back pressure, stripping, and ejection). Stroke accuracy and synchronization between slide, vee-ring, and back pressure systems should be verified under operating conditions.
Mechanically, inspection should include slide guidance, frame condition, die clamping surfaces, and wear at high-load interfaces.
For the uncoiling line, rollers, straightener function, strip tracking, and lifter operation should be tested across the full stated width and thickness range. Electrical systems, safety interlocks, and emergency circuits should be confirmed functional, noting that control system details are not provided.
3. Typical Industrial Applications
Based on the stated forces, strokes, and strip handling capacity, this press is suited for fineblanking of precision steel components requiring high edge quality and dimensional control. Typical applications include automotive and industrial drivetrain parts, safety-critical stamped components, and precision blanks produced from strip material up to 10 mm thickness, provided tooling and material specifications align with the press capabilities.
4. Common Risks in Used Machines
Common risks for used fineblanking presses include hydraulic wear or leakage, reduced force consistency, and misalignment affecting part quality. For retrofitted machines, risks may also involve incomplete documentation, non-original component integration, or mismatches between upgraded capacity and legacy structural elements. Wear in uncoiling and straightening equipment can impact strip flatness and feeding reliability.
5. Maintenance and Service Considerations
Maintenance requirements depend on operating hours and service history, which are not provided. Regular attention should be given to hydraulic oil condition, seals, valves, and cooling, as well as slide guidance lubrication and die clamping surfaces. The uncoiling and straightening systems require periodic inspection of rollers and hydraulic components.
Confirmation of FEINTOOL service support, availability of retrofit documentation, and access to hydraulic and electrical schematics is advisable to ensure long-term serviceability.
Final Note:
While force ranges, strokes, and strip handling parameters are clearly stated, critical details—such as control system type, safety certification status, and detailed retrofit scope—are important. These elements should be verified through documentation review and operational testing before forming final technical conclusions.
