Model Coverage

Feintool Press Models We Service

Our engineers have 10-20+ years of field experience across every Feintool fine blanking press generation — from the relay-controlled GKP series of the 1980s through the HFA general-purpose platform and MFA compound-forming series, to the current XTF mechanical-hydraulic platform. Each generation has distinct hydraulic architecture, control hardware, and failure patterns that dictate a different refurbishment approach.

Feintool XTF Series

The XTF (X-Tra Force) platform is Feintool's flagship mechanical-hydraulic fine blanking press, covering 200 to 800 tons. Its four-cylinder hydraulic architecture — main ram, V-ring, counter-pressure, and ejector — provides independently programmable forces that deliver the edge quality and flatness demanded by automotive safety parts. The most common XTF models we refurbish include the XTF-200, XTF-320, XTF-500, and XTF-800.

Typical age at first major service: 12-15 years of continuous three-shift operation. The mechanical frame and guiding columns are engineered for 30+ years of service life — what fails first is the hydraulic system, specifically the axial-piston pump volumetric efficiency, the proportional valve response characteristics, and the V-ring cylinder seal integrity.

⚙

XTF Series (200-800T)

Mechanical-hydraulic platform. Four-cylinder architecture with independently programmable forces. Common failure: hydraulic pump wear at 12-15 years, proportional valve drift, V-ring cylinder seal degradation causing 10-15% force drop.

⚙

MJP Series (100-200T)

Compact fine blanking press for smaller components. Valve block erosion is the dominant failure mode — the integrated hydraulic manifold develops internal leakage paths that reduce counter-pressure stability. Control hardware typically runs proprietary Feintool PLCs with limited spare availability.

⚙

GKP Series (160-500T)

Older-generation fine blanking press, many still in production after 25-35 years. Relay-based control systems are the primary obsolescence driver. Guiding bushing degradation is common after extended high-tonnage operation, requiring re-boring and bushing replacement.

⚙

HFA Series (400-880T)

Feintool's classic general-purpose platform (HFA400, HFA630, HFA880). The HFAplus variant adds upgraded CNC and hydraulic response. Common service: proportional valve replacement, HMI migration from legacy Feintool controllers, and main cylinder seal overhaul at 10-15 year intervals.

⚙

HFAspeed & MFA Series

HFAspeed: high-speed variant optimized for door lock and latch components at up to 100 SPM — flywheel and clutch inspections critical. MFA (MFA1600, 1600T): compound-forming press supporting bending and drawing after blanking; hydraulic circuit complexity doubles, requiring specialized manifold diagnostics.

⚙

HLT Long-Bed & Regional Models

HLT-1250: long-bed variant (1250 mm die area, 4000 kN blanking + dual 500 kN V-ring) for complex progressive dies. Regional models include HFT7000 (700T), 8800plus (880T), and 6300smart (630T). We reverse-engineer discontinued hydraulic and control components for all legacy Feintool platforms.

Failure Analysis

Common Failure Points by Feintool Model

Understanding which components fail — and when — is the difference between a targeted 3-day repair and a full 8-week refurbishment. Our diagnostic process begins with a site survey that measures the specific symptoms each model exhibits.

Feintool press diagnostic inspection and failure analysis

XTF Hydraulic Pump Wear (12-15 Years)

The Bosch Rexroth axial-piston pumps on XTF presses lose volumetric efficiency after 12-15 years of continuous operation. The symptom is gradual: cycle time increases by 5-10%, tonnage buildup at the start of the shear phase slows, and the press may fail to reach rated force during high-speed stroking. Our diagnostic measures pump output flow at rated pressure and compares it against the factory baseline. When flow drops below 85% of nominal, pump reconditioning or replacement is indicated — typically a 5-day on-site intervention with 12-month warranty.

MJP Valve Block Erosion

The MJP series uses an integrated hydraulic manifold that distributes flow to all four force circuits. After 10-15 years, cavitation erosion creates internal leakage paths between adjacent channels — most critically between the V-ring and counter-pressure circuits. The visible symptom is counter-pressure fluctuation of ±15-20% during the shear phase, which directly degrades edge quality on the part. Manifold replacement requires reverse-engineering the original Feintool casting and machining a replacement — a capability we maintain in-house.

GKP Guiding Bushing Degradation

GKP presses rely on cast iron guiding bushings that undergo progressive wear from high-tonnage cyclic loading. After 20-30 years of operation, bushing clearance exceeds the 0.02 mm specification, producing visible ram tilt that shows up as uneven die-roll height across the part — one edge has 0.3 mm die-roll while the opposite edge has 0.8 mm. Our refurbishment re-bores the bushing housing, installs replacement bushings machined from bearing-grade bronze, and regrinds the guiding columns to restore the original clearance and ram parallelism to 0.01 mm/100 mm.

Refurbishment Scope

Full-Scope Feintool Press Refurbishment

A complete Feintool refurbishment addresses every system that degrades over the press lifecycle — hydraulics, controls, guiding, and precision geometry — in a single coordinated project that returns the press to 70-85% of new-machine capability.

Hydraulic Circuit Rebuild

The hydraulic rebuild begins with complete system drainage, reservoir cleaning, and a full component inventory. Every hydraulic pump is bench-tested for volumetric efficiency at rated pressure — pumps below 85% are reconditioned with new cylinder kits and valve plates, or replaced with genuine Bosch Rexroth equivalents. All proportional and directional valves undergo response-time testing on our valve test bench; valves with drift exceeding 2% of commanded position are replaced. Every seal in the system — V-ring cylinder, counter-pressure cylinder, main ram, ejector, and all line connections — is replaced with NOK or Trelleborg equivalents matched to the original Feintool seal specifications. Cylinder bores are honed to restore surface finish, rods are inspected for chrome plating integrity, and the complete hydraulic circuit is pressure-tested at 1.25x rated pressure before commissioning.

CNC Control Retrofit

For XTF presses with obsolete Feintool PLCs and for all GKP presses with relay-based controls, we perform a complete CNC retrofit. The legacy control hardware is replaced with a Siemens 840D sl or Beckhoff TwinCAT system, selected based on the press's existing sensor infrastructure and the buyer's maintenance team familiarity. The retrofit preserves all hydraulic safety interlocks, stroke sequence logic, and force monitoring functions while adding recipe storage, real-time force curve display, alarm diagnostics with timestamp logging, and remote connectivity for our diagnostic support service. The new HMI is installed in the original control panel footprint — no external additions, no panel butchery.

⚙

Guiding Column Regrinding

Guiding columns are measured for straightness, roundness, and surface finish. Columns with wear under 0.05 mm are reground in-place using portable grinding equipment. Columns with deeper scoring or galling are removed, reground at our Huangshi facility, hard-chrome plated, and finish-ground to restore the original tolerance band. Replacement bushings are machined to match the reground column diameter, maintaining the 0.01-0.02 mm running clearance that Feintool specified at factory assembly.

⚙

Ram Parallelism Restoration

Ram parallelism is the single most critical geometric parameter in fine blanking — it directly determines part flatness and edge quality uniformity. We measure parallelism at four positions across the ram face using precision dial indicators, identify the high and low corners, and adjust the guiding system and lower die seat to bring parallelism within 0.01 mm/100 mm. The result is verified with a production trial using the customer's die and material, measuring die-roll height variation across a 50-part sample.

Timeline detail: On-site refurbishment (3-6 weeks): Suitable for hydraulic rebuild, seal replacement, CNC retrofit, and guiding regrinding where the frame remains in position. Our team works in parallel with your maintenance staff to minimize learning curve. In-shop refurbishment (8-12 weeks): Required when frame welding, stress-relief annealing, or column replacement demands removing the press from its foundation. The press is transported to our Huangshi facility, rebuilt, load-tested, and reinstalled with re-leveling and production trial.

Parts Supply

Reverse-Engineered Spare Parts for Discontinued Feintool Components

Reverse-engineered spare parts inventory for Feintool fine blanking presses

Feintool's OEM parts catalog is comprehensive for current-production models, but the XTF predecessor platforms and all GKP series components have been progressively discontinued. When a GKP-250 needs a replacement V-ring cylinder and the OEM part has been out of production for 15 years, the options are: find a used part with unknown remaining life, or have it reverse-engineered and manufactured to specification.

We maintain a library of reverse-engineered drawings for discontinued Feintool components — hydraulic manifolds, valve blocks, cylinder assemblies, guiding bushings, seal plates, and ram components — built from measurements taken during previous refurbishment projects. Each replacement part is manufactured from material certified to EN 10204 3.1, machined to the original Feintool tolerance specification, and bench-tested before installation. For critical hydraulic components, we provide dimensional inspection reports and material certificates with every shipment.

Common reverse-engineered parts: GKP valve manifolds, MJP integrated hydraulic blocks, XTF cylinder seal kits (NOK/Trelleborg equivalent), guiding bushings (bearing-grade bronze), V-ring piston assemblies, and ejector hydraulic cylinders. Lead time for stocked reverse-engineered parts: 3-5 business days. Custom manufacturing from measurement: 2-4 weeks.

Remote Support

Remote Diagnosis for Feintool Presses

Before dispatching a field team, our remote diagnosis service connects to your Feintool press control system — whether it's the original Feintool PLC, a previously retrofitted Siemens system, or a Beckhoff TwinCAT installation. We read PLC alarm codes, hydraulic pressure curves at each stroke phase (fast approach, V-ring engagement, shear, counter-pressure, ejection), and servo encoder position data in real time.

This remote assessment resolves 60-70% of reported faults without an on-site visit. For the remaining 30-40% that require physical intervention, the remote diagnosis produces a condition report with specific component-level recommendations, enabling a fixed-scope quotation before our engineers arrive — no discovery charges, no open-ended billing.

Compatibility: All XTF models with PLC-based controls, MJP models with accessible diagnostic ports, and GKP models that have been previously retrofitted with modern controls. For GKP presses still running original relay logic, we provide phone-based troubleshooting with photo and video support, supplemented by on-site assessment when needed.
