Metal — Open questions

Verify the exact GUANGDU/controller revision, production-code interpretation and serial identifier; obtain the matching manufacturer's original manual and any applicable service/electrical documentation.

Resolve M2 holder availability versus the arm's M3 minimum. Publish an approved operating limit rather than extending the rating from the chuck inventory. Confirm material-specific maximum sizes; the nominal M20 rating is not proof that every material or tap is suitable.

Inventory each GT12 holder by DIN/ISO dimensional standard, thread-size label, actual shank diameter, square size and clutch type. Inspect the M18 and other large holders recalled as non-clutch types; do not turn “M18, IIRC” into a verified inventory entry.

Confirm that the preset mechanical clutches remain correct; record any measured calibration and permitted maintenance method. The two-hole outer ring is a torque adjuster, not the routine tap-release control.

Check the electronic torque function: it was photographed Off and later reported nonresponsive. Verify its actual behavior, units and protection before relying on it; do not substitute it for secure clamping or a verified chuck clutch.

Demonstrate normal stopping, jam recovery and emergency isolation for both manual and automatic modes. Identify whether a dedicated emergency stop is fitted; the visible red rocker is a power switch.

Verify workholding after the April 2026 near-miss: clamp the workpiece and restrain the vise/fixture to the bench. Record available clamps/bench holes, column anchoring and any completed bench modification.

Demonstrate ordinary depth setup, true thread pitch, displayed depth accuracy, reverse speed and automatic-cycle behavior. Document separate approval/setup for deep-hole cycles (specified in revolutions), left-hand threads and horizontal/head-orientation changes.

Finish/check organizer labels, storage locations and DIN/ISO slot mapping; link the printable model if available. Local January documentation describes hidden magnets and Gridfinity-compatible bases.

Confirm the machine's current instruction/contact, booking, cost and usage-log requirements. None has been verified specifically for this arm.

Record suitable tapping fluids, supported tap types/materials, service responsibilities and checks of the balance struts, pivots, head alignment, coupler retention, cable and controls.

Photograph the installed rating plate and record supply, power, speed, serial number and revision; confirm applicability of the current manual to the older local housing/storage layout.

Identify the installed wheel: maker/part number, CBN or other abrasive, dimensions, grit, speed rating, condition and compatible drill materials. Confirm replacement stock; an unidentified loose stone or generic “diamond” wording is not proof of compatibility.

Inventory and label the actual collets and holder: nominal diameter, clamping range, series and condition. Verify usable drill diameter/length limits; the manual's initial ~35 mm projection is not a minimum overall length. Resolve the inconsistent “2–13 (15)” text without expanding the stated 3–13 mm range.

Confirm the mapping and operation of the upper lip-relief and point-splitting fixtures, their indexing pins and current geometry. Demonstrate all stages on this machine; keep the shared point angle at 118°.

Check alignment, clamping, repeatability and the measured trial-drill point/clearance geometry with a competent maintainer. Record results in the log; establish who may adjust calibration and what drill types/geometries are supported.

Demonstrate normal stopping and emergency power isolation. Identify whether any dedicated emergency stop is fitted, and verify switch, cable, enclosure, stability and access to controls.

Confirm current instruction/contact, course, booking, fee and usage-log arrangements. No machine-specific requirement was verified in the reviewed sources.

Establish suitable fine-dust collection/cleanup and service responsibility. Prefer controlled brush/filtered-vacuum cleanup to blowing dust around; check any proposed coolant or unusual material setup before approval.

Record present electrical connection/protection and supply frequency, which are not established by the plate photographs. Keep any measured spindle-speed checks separate from the nominal chart values; do not substitute E100S or modern Arboga instructions.

Identify the actual spindle taper, chuck arbor at both ends, chuck model/gripping range and any sleeves. Resolve the local MK2 versus MK3 accounts against the installed assembly; do not select replacement tooling solely from an old Slack recollection.

Check and document chuck/bit runout, arbor fit/retention, quill travel and depth-stop operation. A historical report of replaced bent arbors does not establish current runout.

Demonstrate table/head-height locks and cranks, load support, cable clearance and travel stops. Check the present arrangement following the resolved January 2024 lock/cable incident.

Inspect and document the ceiling-securing arrangement, base fixing and stability; preserve the securing described in January 2026 until a competent maintainer approves any change. The photograph does not prove floor-anchor holding strength.

Verify guards, normal stopping, emergency isolation, electrical protection and any no-voltage release. Identify the fitted breaker's exact model, current setting and wiring from the installed device; the GV2ME06 carton in a historical photograph is not proof of the fitted model. A historical pedal proposal does not establish a fitted pedal.

Confirm current instruction/contact, course, booking, fee and usage-log arrangements, suitable drilling/cutting-fluid practices and available clamps/fixtures.

Record the installed spring kit's version and parts/drawing reference, and confirm its kit-specific servicing/adjustment procedure. Keep original counterweight instructions separate from the fitted spring mechanism.

Identify the intended lubrication cups/holes and current suitable lubricant, quantity and service interval. Do not fill the gear casing with oil or generalise a different model's greasing method.

Document suitable sheet-metal tooling and clamping/backing arrangements following the February 2026 local grab report. Keep any proposed setup consistent with the Metal room's material rules.

Photograph the maker/model, motor and serial plates and a readable speed chart. Keep the existing manual and specifications, but distinguish their nominal ratings from measured machine performance.

Document the current readout procedure and the exact function/selector mapping for the labelled front controls.

Record the installed machine/motor plates and serial number; resolve the existing work-area and motor-power placeholders from matching documentation or the installed plates.

Check the current ER25/tool inventory against the dated November 2015 list, and determine whether the old tailstock-centering and replacement-lever plans have since been completed. Add confirmed present information to the guide and dated work to the log.

Photograph the installed model/motor plate and serial number; confirm the exact LC1230 variant and rating rather than deriving them from the current overall photograph.

Check and record the current blade inventory, part numbers, material markings and matching magnetic labels. The photograph does not establish which blade is mounted or its condition.

Obtain a complete original DS 7211 D operating/maintenance manual. Targeted searches and Metabo's public manual search did not yield one; a modern DS 200 manual is not a verified substitute.

Record the fitted wheel labels, actual dimensions and flange/mounting arrangement for future replacement orders, including the 20 mm finer wheel. Check replacement compatibility against the machine and manufacturer instructions.

Obtain a complete matching ES 160 machine manual. The recovered manufacturer cover is not an operating manual; BGM-100 documents cover the accessory system.

Record actual spindle/reducing-bush and flange dimensions, fitted wheel label and wire-brush specification for future replacements. Preserve the machine's 160 × 20 mm maximum and verify replacement fit and speed rating.

Record the exact purchased JH-1A/JH-1B/JH-1C variant, fitted auxiliary-lens marking and current working distance. Resolve the manual/listing differences in pupil spacing, mount opening and broad distance ranges from the actual setup before using them for fitting or replacement purchases.

Check that the mount holds the installed head securely and the storage cover protects both objective and eyepieces. Record any actual adjustment or repair in the log; the manual's friction controls do not specify a spring-preload method.

Document the current illumination, power supply, switches and accessory inventory. The manual lists OK65 / 5 V DC USB for A/B packages and the ball vise/clamps for B; that does not establish which items are now fitted.

Confirm ownership/loan status, local instruction/contact and any access or booking arrangements. Procurement involvement does not establish personal ownership.

Obtain and retain the original serial-specific SM/400 operating/parts instructions and electrical diagram. A four-page German SM300/SM400 scan is readable online; no verified unrestricted PDF was found. Current wiring must reflect the overhaul rather than assuming the old diagram still applies.

Record final supply and all motor, lamp and IDEAL welder ratings; document completed electrical work, checks and the rebuilt start/stop/isolation/emergency controls. Record commissioning results in the child log.

Measure the actual blade loop and usable tensioning range before replacement orders; resolve the seller's 2780–2980 mm range against the installed machine. Establish allowed width/thickness, fitted blade material/tooth pitch and matching upper/lower guide inserts.

Confirm the actual default blade installation and record its maker/product, construction, length × width × thickness, variable pitch, break-in status and matching upper/lower guide inserts. Establish its material/section/radius limits, plastic suitability and speed/lubrication guidance; the intended 10 mm / 10/14 TPI setup is not yet an installed specification.

Confirm usable throat, work height, table dimensions/tilt, guards, table insert, wheel tyres and blade tracking. Inventory any optional straight-cutting, weight-feed or band-filing accessories before adding their operating procedures.

Identify the IDEAL welder model, serial, voltage and capacity, plus grinding unit. Obtain matching instructions and establish demonstrated weld/anneal/dress/inspection procedures, including compatibility with proposed bimetal stock.

Establish suitable lubrication grades/levels and service intervals; confirm cutting-fluid arrangements, supported materials and actual blade-speed/selector checks after the overhaul.

Record member instruction/access, booking, fees, logging and contact arrangements before general use; these have not been confirmed for this newly acquired machine.

Photograph the installed machine/motor plates and serial number, complete machine and final controls. Record VFD make/model, electrical installation/protection and the approved parameter/wiring record.

Establish allowed speed/load/duty limits, actual rotation, motor cooling and wheel compatibility. The factory 2,850 rpm and Vario data do not define the local permitted range; the shared manual lists S6 60% duty.

Document and test pedal behavior, normal stopping/coast-down, emergency stopping, safe isolation and power-loss/fault/reset behavior. Do not infer momentary/dead-man operation or automatic restart prevention from the word “pedal.”

Record fitted wheel/compound inventory and rated speeds, spindle sleeves/flanges/cap nuts, shaft covers, mounting stability and required guarding. Resolve conflicting nut-thread directions on manual pp. 21 and 36 before publishing a wheel-changing procedure. Measure the actual envelope/mounting pattern; the catalogue and p. 16 drawing differ.

Establish dust extraction and cleanup for the approved materials/compounds. Check operation throughout the allowed VFD range; factory current-sensing extraction may not trigger at low speed.

Demonstrate polishing contact area/orientation, secure workholding for small/irregular parts and the approved pedal sequence. Confirm instruction/contact, access, booking, fee and logging arrangements; the former machine's entries do not apply automatically.

Record completed commissioning checks and explicit release in the log, then replace the main guide's commissioning placeholders with the verified procedure.

Inspect the current pressure-plate pin, its seating/fit, pressure plate, forming blocks and fasteners. Establish whether the 2025 faults were repaired; record actual work/results before removing the main guide's condition warning.

Confirm the present mounting, stability and stock/lever sweep clearances. The last reviewed report describes a temporary wall mounting near the hydraulic press. Do not assume the proposed horizontal vise adapter was completed.

Inventory and photograph all forming plates, clamp/seat variants, radius labels, bend-stop parts and length gauge. Check fit before ordering substitutes; the October 2025 discussion identified different pin and pressure-plate geometry on a suggested replacement version.

Check the angle scale, stop retention, repeatability and bend alignment with suitable sample work after the tool is confirmed sound. Record material, section, tooling, radius and released angle; the manual's capacity table is not a current load-test result.

Establish suitable material/radius combinations and any hot-working method. The Millart manual does not state steel strength/grade or hot-working temperature; other UB-100 suppliers' higher figures do not define local limits.

Record a local demonstration/contact and an appropriate cleaning/lubrication routine for this version. Photograph any readable machine plate and record the exact supplier/version if available.
