Machine at a glance

Before you inspect: make sure the machine is indeed the BF 5200 (or “BF 5200” series bed-type) with the specs you expect.

• According to MTE’s catalogue the BF series “bed type milling machines” cover X-travel up to ~5,000 mm (i.e., the BF-5200) with Y = ~1,000‐1,200 mm and Z up to ~1,000‐2,000 mm.
• Example spec sheet for BF 5200: table surface ~5,200 × 1,200 mm; X ~5,000 mm travel; Y ~1,000‐1,250 mm; Z ~1,000‐2,000 mm depending on configuration.
• Spindle typically ISO-50 taper (DIN 69871), speed up to ~4,000 or optionally up to ~6,000 rpm, power ~30‐32 kW (depending on head) for some configurations.

Make sure the equipment you’re looking at matches the claimed travel, table size, spindle spec, etc.

Pre‐Purchase / Inspection Checklist

1. Verify identity & documentation

• Confirm model, serial number, manufacture year, original spec.
• Check original documentation/manuals from MTE: travel spec, tool changer option, head options.
• Ensure claimed size (table 5 m length) is correct and matches your usage.
• Confirm it is truly built in Spain (MTE is Spanish based).
• Ask for past service logs, maintenance history, overhaul records, any major repairs.
• Ask how many hours the machine has been used, what kind of work (heavy milling vs light).

2. Structural & mechanical condition

• Check the bed (the large flat bed surface), the table and support structure for wear, cracking, damage, especially in a large machine like this. The BF series emphasises “flat guides and optimum vibration damping” for heavy applications.
• Inspect guideways, ball screws/ways (for any axial/backlash play, wear, corrosion). On large table machines the guideways may have wear from heavy loads.
• Verify table flatness and T‐slot condition: check for damage, slot width variation, etc. Example spec: 7 T-slots of 22H12 on table ~5,200×1,200 mm (for BF-5200) per specification.
• Check spindle head: runout, bearing play, excessive noise during rotation. If the head includes a swiveling or indexing capability (some BF machines include automatic head options), check that indexing mechanism and gear (if present) are in good shape.
• Inspect the ram/cross-slide and vertical travel for smoothness and no sag/tilt (especially critical for tall Z travels).
• Confirm there is no excessive vibration during a test run (which may indicate structural fatigue or looseness).
• Check hydraulic/pneumatic systems (if present) for leaks, correct pressure, functionality.

3. Control system, drives & auxiliary equipment

• Identify the CNC controller (e.g., Heidenhain TNC 640, iTNC530, or other) and check software status, backups, parameter history. Example listing: BF 5200 with Heidenhain iTNC 530.
• Test each axis (X, Y, Z) under manual (jog) and automatic feed for smoothness, no jerking, correct feed rates.
• Test spindle under load: speed up, slow down, measure actual rpm, observe temperature and behavior under light cut.
• Check tool changer (if included): does it index properly, any tool change errors, magazine integrity. Some BF machines offer 24, 40, 60 tool positions.
• Check the coolant system: pumps, filters, hoses, coolant-through-spindle (if option) and cleanliness.
• Inspect the electrical cabinet: look for signs of overheating, burnt components, cleanliness, proper labelling.
• Ensure lubrication/greasing system is operational (automatic lubrication of ways, ball screws if required).
• Check condition of wiring, motors, drive modules, feedback systems, safety interlocks.

4. Alignment, accuracy & performance tests

• Perform alignment checks: table flatness, perpendicularity of axes, straightness of X-axis travel, repeatability of table positioning.
• Measure machine accuracy under load: a trial cut is best—check surface finish, dimensional accuracy, repeated runs.
• Check backlash, axis play (especially X and Y on long travels), ball screw wear.
• Conduct spindle run‐out test (e.g., with dial indicator). If spindle bearings are worn the run‐out may exceed tolerances.
• Check thermal behaviour: run the machine for some time and check drift or heat‐induced errors.
• Ask for previous accuracy test reports if any (especially important for mold/die or precision work).
• Take note of any past collisions or major repair history (these often degrade accuracy significantly).

5. Usage history & parts availability

• Ask: what type of work was this machine doing? Heavy components, long runs, high‐load milling?
• A machine used for heavy continuous work may have more wear in ways/spindles.
• Ask about part replacements: have major components (spindle bearings, ball screws, guideways) been replaced or are near replacement?
• Check availability of spare parts from MTE (for Spain/Europe) and shipping to your country. Large machines may have long lead times for parts.
• Check for accessories included (e.g., tool magazine, rotary table/4th axis, probing systems). Do these function and are they included in price?
• Request clear documentation of condition, photographs, videos of machine under power (if possible).

6. Risk & cost factors

• Transport, disassembly/assembly, foundation, installation cost will be significant for a large bed‐type machine (table ~5 m long).
• Check if the machine will require re-grouting, re-leveling, or major alignment after shipping. Budget these.
• If the machine has been idle, check condition of unused components (rust, stale coolant, seals hardened).
• Consider retrofit/upgrades: older controls may require modernisation; guard/cover systems may need updating for safety compliance in your country.
• Consider power consumption and whether your site in your region is ready (voltage, phase, kVA).

Pre‐Installation & Installation Readiness

1. Site preparation

• Floor: The machine is large and heavy—ensure your foundation can support the machine plus workpiece weight. A bed-type machine with table ~5 m likely requires robust concrete plinth, vibration isolation, proper anchoring.
• Clearance: Need sufficient height for the machine’s vertical travel + guard, doors, crane/hoist for installation and large workpieces.
• Access: Ensure delivery route allows forklift/crane into the hall, placement of machine.
• Power supply: Verify voltage, phase (likely three‐phase), frequency, kVA requirement (from spec sheet ~32 kW spindle motor plus drives etc). Check your facility in Bursa can accommodate.
• Environment: Temperature control, ventilation, chip removal, coolant drainage and disposal system. Large machines often generate significant chips and coolant fluid.
• Safety: Guards, emergency stops, safety interlocks, proper wiring to local regulations (CE compliance if applicable).

2. Installation & alignment

• Place machine, anchor bolts, grout (if required), level machine using precision levels and shim/adjust until within tolerance.
• After initial mounting, run alignment tests: check X & Y axis orthogonality, Z axis alignment, table flatness. Use dial indicators/laser alignment tools.
• Calibrate CNC control, zero offsets, ensure tool magazine indexing, spindle alignment.
• Commission spindle: run at full speed, monitor vibration, temperature, noise.
• Test under real load: Place sample workpieces and run production style cut to verify machine meets your required tolerances and cycle times.
• Ensure coolant and chip management systems operate correctly (chip conveyor, coolant filtration).
• Train personnel: operators, maintenance staff must be trained on this particular machine (especially with any custom or oversized tooling).

3. Documentation & handover

• Ensure you receive as‐installed documentation: machine serial, major component serials, configuration list, drawings, manuals, software versions.
• Establish baseline measurements (table flatness, guideway wear, spindle run-out) immediately after installation for future comparison.
• Create maintenance schedule: lubrication, ball screw checks, spindle bearing inspection, coolant/filter maintenance, tool-changer checks.
• Ensure spare parts list: buy critical spares upfront (seals, filters, tooling components) to avoid downtime.
• Confirm warranty or guarantee from seller (if any) or understand the “as-is” condition.
