Guangzhou Machine Tool: fit the loaded setup.

G-XK1203: 2200 mm Y travel is not a 2200 mm passage

Guangzhou Machine Tool's range includes turning and vertical, horizontal and gantry machining. Its G-XK1203/1202 page describes a moving table and fixed crossrail. For a large die, plate or housing, separate the loaded workpiece entering the frame from the cutter's travel along the crossrail.

Use four different envelopes

Table and load

3000 × 1200 mm; 12 tonne loading reference

Axis travel

X / Y / Z: 3000 / 2200 / 800 mm

Column passage

1800 mm between the columns

Spindle-nose window

320–1120 mm above the table

Include fixtures, projecting clamps and all blanks in the mass and physical passage. Then check each cutting feature, holder projection and retract position in the travel and nose window. The larger Y travel does not allow a loaded 2200 mm-wide block through an 1800 mm column opening.

For a side face or deep pocket, obtain the head/attachment drawing and a collision check rather than assuming an attachment is included. The shorter G-XK1202 shares this page but lists a 2000 mm table/X stroke and 8 tonne load; these are not the 1203 figures.

For a smaller fixture, compare the actual G-VMC column

G-VMC650, 850 and 1160 share one original page. The reference image is marked G-VMC650. Use the verified 650 setup for the first fixture check; an 850 quotation needs its own axis/clearance drawing because the original 850 column lists a 500 mm Z stroke beside a 110–810 mm nose window.

G-VMC650: locate the complete fixture

Its table is 750 × 450 mm with 500 kg loading reference, X/Y/Z travel 600/450/480 mm, nose-to-table range 150–630 mm and spindle-centre-to-guide reference 500 mm. Include the plate, clamps and loaded parts; a 750 mm table length does not give 750 mm X cutting travel.

The page lists 18 mm T-slot width and 135 mm spacing for 650. Check fixture positions, the furthest feature and the short-tool approach near the minimum nose position, then verify the longest holder at retract and tool change.

For 850, agree one current drawing resolving Y/Z travel and the nose window before planning a tall part or a short tool. The shared source lists BT50 and 8000 rpm across the VMC range; verify the selected spindle, pull stud, tool changer and motor duty rather than carrying assumptions from similarly named machines.

Keep guideway and spindle-drive alternatives separate

The gantry source lists BT50, X/Y rapid 12 m/min and cutting feed 5–6000 mm/min. Its Z rapid row has an inconsistent unit, so use a confirmed axis-speed sheet for cycle planning. A tool/holder interface, maximum rapid or short-time torque figure does not establish the complete cutting process.

Make the fixture and the released workpiece part of acceptance

1. Locate and reach

   Provide material/heat treatment, blank allowance, datums, fixture drawing, loaded mass and centre of gravity. Check clamps and holder projection at the deepest cut, near-table approach, side face and retract. For the gantry, demonstrate passage and all intended head/attachment positions.

2. Cut with the quoted package

   Record selected guides, spindle drive, tools, holders, coolant/chip removal and motor duty. Trial the roughing and finishing operations with the proposed fixture. Measure full elapsed time, including tool changes, probing, chip clearing and loading; rapid travel alone is not output.

3. Inspect after release

   The source gives axis positioning/repeat-positioning references using ISO230-II wording. Agree the current applicable test procedure and separately inspect the released part's drawing datums, flatness, bores, finish and dimensional relationships. Record thermal and clamping conditions; an axis result does not certify every finished surface.

A 45 tonne gantry needs a different site plan

The G-XK1203 table gives 9.3 × 5.3 × 4.5 m outer dimensions and 45 tonnes net mass. Add moving-table clearance, head/tool exchanges, conveyors, service access and installation access to the site plan. Obtain foundation, floor-loading, lifting and utility drawings for the actual build. Neither outer dimensions nor a 12 tonne table reference describes foundation loads or a transport plan.

Guangzhou Machine Tool's company page traces the factory to 1958 and describes its 三环箭 brand, machining/assembly history and development of turning and machining-centre systems. It identifies Guangzhou Industrial Investment Holdings Group as its parent. Confirm the contracting entity, actual build site, configuration revision and destination service scope in the quotation.

The standards platform record for GB/T 26676-2011 names 广州机床厂有限公司 as a drafting participant in the machine-tool electrical withstand-voltage test specification; it records continued validity at the 30 May 2025 review. Drafting participation is not an electrical test certificate for a specific machine. Request the delivered electrical documents and test records, along with the agreed geometric and part-acceptance package.
