Here is a detailed inspection-to-installation checklist specifically tailored for purchasing a PARPAS SL 60 CNC bed-type milling machine (made in Italy) — you can use this as a professional step-by-step guide from inspection through to installation on site . I’ll provide a breakdown of key areas: pre-inspection / seller due-diligence, on-site inspection & test, logistics & transport, installation & commissioning, and after-installation sustainability. This will help you minimise risk, avoid hidden costs, and ensure a smooth integration into your workflow.

1. Pre-Inspection / Seller Due-Diligence

Before visiting the machine or committing, make sure you gather and verify the following information from the seller:

a. Machine identification & history

• Confirm the exact model: SL 60 (or SL 60 TRT variant) — e.g., I found a listing: “Used PARPAS SL 60 TRT” with X = 2,000 mm, Y = 1,200 mm, Z = 750 mm.
• Year of manufacture, serial number. For example: “Year 1998 Model SL 60” in one listing.
• Machine hours (if available), number of shifts used, duty cycle (light vs heavy use) — according to used-CNC buying guidance this is important.
• Maintenance/service history: lubrication intervals, spindle rebuilds, way‐cover replacement, coolant system maintenance.
• Control system details: Which CNC control is installed (Heidenhain, Selca, etc)? E.g. one listing: Heidenhain TNC425.
• Confirm the tool‐holder/spindle taper: many SL 60 machines use ISO 50 or BT/ISO50 toolholders.
• Availability of original documentation: electrical drawings, parts manuals, CE certification (for European machines). One ad shows “Electrical drawings: Yes; CE certification: Yes.”
• Confirm that there are no legal or logistic impediments: export restrictions, customs in your country , VAT/tax issues.

b. Compatibility with your requirements

• Work envelope: Does the machine’s X-, Y-, Z-travels meet your needs for the machines you plan to trade/sell on CNCBUL? Example: one spec lists X = 2,000 mm, Y = 1,200 mm, Z = 750 mm for SL60 TRT.
• Spindle speed, power: Ensure it suits the materials you will be machining. For SL60 one spec: 4,000 rpm.
• Tool‐changer/ATC: How many tool positions? One spec: 60 tools.
• Precision/repeatability specs (if available).
• Floor space, weight: e.g., one listing shows machine total weight 10,000 kg and footprint 5,300×4,520×3,000 mm.
• Check whether spare parts/support are available in your country or regionally for PARPAS machines (controller, spindle bearings, etc).

c. Ask for photos/videos

• Exterior condition: bed surfaces, table T‐slots, way covers, ram or saddle.
• Spindle nose and tooling interface: check wear.
• Undercarriage: any leaks from hydraulic/pneumatic systems, coolant tank condition.
• Electrical cabinet: wiring neatness, dust, corrosion.
• Running machine (video) if possible: listen to spindle, check axis movement, tool-changer cycle.

d. Prepare questions for the seller

• What material and application was the machine used for (light finishing vs heavy roughing)?
• Has it ever had a crash (table vs column, head tilt, ram impact)?
• Has the spindle been rebuilt? What are the spindle bearings’ condition?
• Are ways (slides) resurfaced or replaced? Are there any known issues with backlash in axes?
• What condition are the way covers and chip guards in?
• Are all originals parts present (e.g., chip conveyor, guard doors, ATC magazine)?
• Are there any known electrical or control issues (fault codes, inconsistent operation)?
• Why is it being sold? (Often reveals wear/maintenance issues.)

2. On-Site Inspection & Functional Test

Once you visit the machine, you need a structured checklist. Here are recommended items:

a. Visual / structural check

• Check bed and table surfaces: Look for deep scoring, dents, gouges in T‐slots, corrosion.
• Verify that table moves smoothly in X, Y, Z (no jerky motion, no binding).
• Inspect saddle/ram or cross‐ram: Check for wear signs, lubrication access.
• Check head (if it’s tilting/rotating): Are bearings tight, any play in A/C axes (if applicable).
• Check way covers: Are they intact, do they cover full travel, any open gaps (which would allow chips, coolant ingress).
• Check for rust/corrosion, especially on large exposed surfaces (bed, column face).
• Check for leakages: hydraulics, pneumatics, coolant, lubrication systems.
• Inspect chip conveyor & coolant system: Condition of tank, presence of sludge or contamination.
• Check electrical cabinet: Enquire about overheating signs (brown/blackened wiring), cleanliness, proper labelling.

b. Spindle & tooling interface

• Insert a clean toolholder into the spindle and rotate by hand (if possible): Check for even contact, no visible pitting or scoring inside the taper. According to used-CNC guides, a damaged spindle taper is a major red flag.
• Run spindle up to full speed (if seller allows) and listen: Any unusual noise, vibration or heat. For example one Reddit post says: > “Run the spindle at several speeds to hear the bearings … rattling or gear whine could be a problem.”
• Confirm ATC functionality: Does the tool-changer pick tools cleanly, drop & pick time consistent, no missed cycles or alignment issues?
• Check drawbar and tool retention system: Any excessive play, damage, or missing parts.
• Check the spindle front bearing diameter (some specs mention 85 mm bearing for SL60) in one listing.

c. Axis movement & backlash / geometry

• Move table/saddle to extremes of travel. Check for backlash in each axis (X, Y, Z).
• Use a dial indicator or ask for test cut (if possible): For example run a circle or simple bore and measure deviation; this type of practical test is advised by users.
• Check for consistent speed of axes, look for signs of wear: e.g., uneven motion, dragging at ends, excessive clearance.
• Check the travel values: Are the full strokes available (compare to spec sheet: e.g., 2,000 mm X, 1,200 mm Y, 750 mm Z in one spec)
• Inspect way lubrication system: Are wipers intact, are there leaks, is the way oil reservoir present and filled.
• Look for large repairs or welding on bed, column, saddle: this may indicate past crashes or serious repairs.
• Check the head alignment and ram if applicable: For example, the head may have been knocked or tilted – look for signs of front face alignment mis‐match.

d. Control system & electronics

• Identify CNC control and verify software version, availability of manuals. As buying guidance says: “Check the machine’s control system & software compatibility.”
• Ask to run some simple program: Home all axes, run a simple machining routine (if permissible) to check functionality of control inputs/functions.
• Check for worn panel buttons, switches, missing covers – this can indicate heavy use or poor maintenance.
• Inspect wiring: Are there any signs of overheating, burnt marks, or broken connectors?
• Confirm servo drives and motors are present and working. Ask for hours or maintenance records (if available).
• Check coolant/pump system: Does the pump run, are there leaks, is the coolant clean or full of sludge?
• Check the hydraulic/pneumatic systems (if used by head or ATC): Are they functioning, any leaks, are hoses flexible or hardened?
• Ask whether there were any control modifications (retrofits, converter replacements) that might affect reliability or spare part availability.

e. Miscellaneous & accessories

• Check worktable load rating (can it handle your largest parts). Some listings for similar models mention e.g., table 1,000 × 1,000 mm in size.
• Inspect guards, doors, safety interlocks: Are they present and functioning? (Important for compliance and safety).
• Check availability of auxiliary equipment: chip conveyor, coolant tank, guard screens, fixtures, tooling.
• Check the machine’s footprint and ensure the exporting logistics and importing into Türkiye (customs, transport) will be feasible given weight/size.
• Ask for verification of machine “under power” status: Many used machine listings mention “under power” which is a positive sign.

3. Logistics & Transport

Once you decide to purchase, you’ll need to plan how to move the machine to your site (or the buyer/exporter’s site) and then install it.

• Confirm where the machine currently resides (country, factory floor) — this affects transport cost, import duties, shipping method.
• Calculate machine weight (e.g., one spec: 10,000 kg) and footprint; ensure your floor/pad at destination can handle load.
• Plan lift/rigging: Bed‐type machines are heavy and may need crane, special transport skid, removal of head or other parts to reduce height/weight.
• Check required disassembly: You may need to remove column head, spindle head, ATC magazine, guarding to load.
• Prepare for customs/import in Türkiye: ensure you have export documentation, CE‐marking if applicable, import duties, VAT, clearance.
• Plan for rigging at destination: Floor levelness, base pouring or grouting, anchor bolts, foundation required (many bed‐type machines require precision foundation).
• Plan for electrical power: Verify voltage, phase, protection, motor circuits match local supply in Türkiye. Also check control compatibility (50/60 Hz, etc).
• Plan for coolant, lubrication, hydraulic systems: You may need to flush, replace old fluids during installation.
• Transport insurance: Cover potential damage during transit.

4. Installation & Commissioning

Once machine is delivered, the proper setup is key to getting productive capability from day one.

a. Foundation and alignment

• Ensure foundation/pad is flat and level, and machine is anchored/grouted according to manufacturer recommendations. Poor alignment leads to inaccuracy.
• After installation, perform machine geometry checks: bed alignment, table flatness, axis squareness, head alignment.
• Use precision instruments (level, straightedge, dial indicator, laser alignment ideally) to verify column to table alignment, spindle orthogonality.
• Check spindle centre height, head tilt/rotation accuracy (especially for the SL 60 if it has bi‐rotative head).
• Run test cuts to verify repeatability and accuracy; check parts dimensional accuracy against your requirements.

b. Conditioning & “break-in”

• Change all fluids: hydraulic oil, coolant, way lubrication oil – used machine will likely need this freshened.
• Clean out coolant tank, replace filters, inspect for rust, sludge, bacteria.
• Clean all way covers, wipe down ways, ensure lubrication reaches all sliding surfaces.
• Run machine without load for some hours to allow any residual wear or settlement to happen; monitor for abnormal noises, vibration, heating.
• Gradually ramp up to production loads—don’t immediately push hardest jobs.

c. Controls, tool-changer, safety

• Verify that CNC control runs all axes, limit switches, emergency stops, etc.
• Check tool-changer under load: pick/drop cycle, no collisions, tool balancing if needed.
• Check spindle reverse, indexing, head rotation (if applicable).
• Restore or calibrate any axis scales/feedback (if the machine has linear scales, encoder).
• Ensure all guards, interlocks, light curtains (if required) are properly functional to meet TÜRKİYE safety standards.
• Program/test a “first part” of your expected production to ensure full suitability.

d. Documentation & training

• Make sure you have the machine’s manuals, parts lists, lubrication charts, etc.
• Train operators: even though it’s used, understanding its specific control interface and quirks is key.
• Set up maintenance schedule: lubrication, way cover check, spindle inspection, coolant cleaning, etc.

5. After-Installation Sustainability & Performance Monitoring

To make the most of your investment and ensure long-term value:

• Track machine performance: uptime, scrap rate, setup/teardown time, tool change reliability.
• Monitor spindle vibration/temperature periodically (to detect bearing wear early).
• Set up a preventive maintenance log: e.g., way cover replacement, coolant change every X months, spindle run‐out checks.
• Keep spare parts list: Especially for machine of this age/model—bearings, seals, way wipers, tooling interfaces.
• Evaluate consumables cost: tooling for ISO 50/BT50, coolant, maintenance items.
• Consider retrofits/modernisations: e.g., newer CNC interface, tool-monitoring, remote diagnostics — because older machines may lack latest features.
• Re-assess ROI: Make sure the machine meets the productivity and quality targets you set when you purchased.
