Start with the part: small-part turning or an 850 VMC-L machining setup

Which features set the first operation?

A component that combines turned datums with off-axis holes or milled faces may need an agreed transfer and second setup. FCL-140's ordinary hydraulic turret is not the FCL-200MC live-tool package described elsewhere in the catalogue.

FCL-140: distinguish swing, cutting diameter and bar passage

470 mm swing ≠ 470 mm cut

The FCL-140 catalogue column gives 470 mm bed swing, 284 mm saddle swing and 260 mm maximum machining diameter. Use the machining figure as the initial cut-envelope check, then prove jaw, holder, turret and tailstock clearance on the actual setup.

57 mm bore ≠ 57 mm bar

The same column gives a 57 mm spindle through-hole but a 45 mm maximum bar passage, with an A2-5 nose and six-inch chuck. Specify the stock diameter, liner, collet/chuck and feeder interface together.

290 mm machining length

The catalogue lists 290 mm maximum machining length and 397 mm between centres. Those dimensions do not remove the space taken by jaws, grip allowance or the tailstock centre. Submit the blank length, gripped length and end-face access.

The page describes a 6000 rpm spindle, a ten-tool hydraulic cam turret and an MT4 hydraulic tailstock. Gang tooling is a separately described option; the FCL-140A column is a different tooling arrangement. Choose the installed tool package from the actual sequence, rather than combining both columns or promising the catalogue's claimed productivity increase.

850 VMC-L: fit the fixture and tool stack inside the travel

Worktable

1000 × 510 mm; published maximum table load 500 kg.

X / Y / Z travel

850 / 530 / 510 mm.

Spindle nose to table

150–660 mm in the 850 catalogue column.

Tool system

BT40 reference, 24-position arm-type ATC; catalogue tool envelope Ø80 mm and 300 mm length.

Count the fixture, part and any rotary unit in the table load. Lay out clamp reach and the furthest toolpath over the 1000 × 510 mm table; the full table is not covered by 1000 mm of X travel.

Stack fixture height, part height and the tool/holder extension against the 150–660 mm nose-to-table range. Check the lowest cut, longest drill, tallest clamp and tool-change clearance. If a fourth axis is required, request its swing, support, added mass and control/postprocessor package; it is an option in the catalogue.

Freeze the machine package before comparing quotations

Prove the cycle that the operator will actually run

1. Turning: retain the real grip and support

   Trial the intended bar/chuck blank, jaw or collet, tailstock condition and tool sequence. Include part-off or unload, the next-stock advance and a restart where applicable. Inspect the specified diameter, roundness, face runout, bore and length using the drawing's datums after release. Keep the grip/support parameters with the results.

2. Milling: include the tallest fixture and longest tool

   Run the datum setup, tool changes, deepest hole/pocket and any second setup. Check reachable surfaces and collisions before cutting. Measure the relationship between features after unclamping, and include loading, probing, chip clearing and tool replacement in cycle evaluation.

3. Separate machine checks from part acceptance

   The VMC webpage cites JIS positioning/repeatability figures, while its linked catalogue uses VDI 3441 entries with different numerical limits. Do not combine those methods into a tighter advertised result. Agree the actual machine inspection standard, travel, temperature and compensation state; separately define the trial-part size, geometry and finish requirements.

Ask for the installed tool/chuck list, electrical and lubrication documents, control and compensation backups, machine inspection record and agreed part-trial report. Repeat the relevant tool or setup change rather than accepting one specially prepared first piece.

Confirm the Suzhou supply and destination-service parties

The official company page identifies 苏州伟扬精机有限公司 in Changshu, Jiangsu. Its navigation and catalogue cover turning, machining centres and grinding equipment, and link to the wider Chevalier business. That does not establish that every global group machine is built, stocked or supported by this entity.

For the quotation, name the contracting entity, actual manufacturing/configuration location, installation provider, training and warranty/service party at the destination. Confirm which control version and regional components will be delivered and who supplies the commissioning records and replacement parts.
