A technical reference to the retained GC, GT and GS turning-centre records: separate tool position, moving member and working limit.
Model material reviewed 8 October 2026 · Technical reference only; transaction services unavailable for this record.
The GT8 Y limit depends on the tool centre.
The original GT8-300Y, GT8-500Y and GT8-500SY tables give two different Y conditions. At spindle centre, the listed range is +50/−16 mm. The +50/−50 mm range applies when the 90° tool centre lies 57–123 mm from spindle centre in X. Removing that condition changes the meaning of the specification.
- Spindle-centre condition
- Y +50 / −16 mm
- Specified 90° tool-centre condition
- Y +50 / −50 mm; X distance 57–123 mm
These are source-specific coordinate limits. They do not describe a symmetrical workpiece envelope through every tool orientation, nor prove that a fixture, holder or adjacent tool clears the machine.
The tables list X/Z/Y rapid traverse as 30/30/10 m/min and unidirectional repeat positioning as 0.003/0.003/0.005 mm in that order. Axis repeat positioning is different from feature position or the accuracy of a released part; the part's datum, support and thermal state remain separate matters.
W is not the same moving member in both 500 models.
| Retained record | Length field in its original table | W / workholding distinction |
|---|---|---|
| GT8-300Y | Maximum machining length 300 mm, configuration-dependent; Z travel 400 mm | 8 in chuck; servo tailstock marked optional |
| GT8-500Y | Maximum machining length 535 mm; Z travel 620 mm | 8 in chuck; W 580 mm explicitly assigned to a servo tailstock |
| GT8-500SY | 600 mm between chuck jaws; Z travel 620 mm | 8 / 6 in main/sub chucks; W 600 mm explicitly assigned to the sub-spindle |
Swipe or focus and use arrow keys on a phone. A jaw-spacing dimension is not a published machining length.
The 500Y introduction uses general wording about main/sub-spindle alignment, but its numerical table names a tailstock for W and lists a single chuck. That introduction cannot establish a sub-spindle package. The 500SY table separately identifies both spindles, their chucks, bores and speeds; its W value should not be copied back to the 500Y record.
All three GT tables distinguish Ø50 mm bar passage from a Ø76 mm main spindle bore. A bore diameter describes one component, whereas bar passage includes the workholding/feed path. Similarly, their Ø340 mm disc turning figure does not establish an arbitrary Ø340 mm by full-length occupied cutting envelope.
The GC entries describe different tooling and spindle records.
GC6-E: short-part reference
The table states CL42/CL30 main/sub workholding, Ø42 mm bar passage, Ø120 mm disc turning and 160 mm maximum machining length. X1/X2 is 145/360 mm; Z1/Z2 is 260/230 mm. The upper Y axis and 12T/70 driven turret are options. The lower tool arrangements are listed separately, so every pictured tool package cannot be treated as included.
GC6-C: upper and lower Y differ
Main/sub chucks are 6/6 in, bar passage Ø45 mm and maximum machining length 555 mm. The product description makes upper Y standard and lower Y optional; the table's ±50/±50 mm row carries the option condition. Its 16-station driven turret differs from the GC8-C entry. The visible table only specifies a main spindle speed/bore, not a complete sub-spindle performance schedule.
GC8-C: separate slide limits
Main/sub chucks are 8/8 in, bar passage Ø60 mm, disc turning Ø260 mm and maximum machining length 550 mm. X1/X2 travel is 220/190 mm, and the travel row labels 690/570/580 mm as Z1/Z2/Z3. The rapid row instead labels Z1/Z2/W; the two labels are preserved as a source discrepancy, not silently harmonised. Upper Y is standard and the tooling row names a 12-station driven turret.
GS6-200Y has its own asymmetric Y range.
The GS6-200Y record identifies a compact hard-guideway turning centre with a composite Y arrangement and oil-cooled synchronous spindle. Its table lists X/Z travel 165/275 mm, Y +35/−22.5 mm and C 360°. These values differ from the GT8 conditional Y geometry and must remain separate.
- Working dimensions
- 200 mm maximum machining length; Ø550 mm bed swing and Ø350 mm swing over the slide. Neither swing entry is named maximum turning diameter.
- Workholding and tooling
- 6 in chuck with 8 in optional; hydraulic clamping; 12T/80 driven turret. The Ø56 mm spindle bore is not a published bar-passage rating.
- Motion and tailstock
- X/Z/Y rapids 16/16/8 m/min; hydraulic tailstock optional, with Ø65 mm quill, 100 mm quill travel and Morse 4 taper in the table.
The speed and spindle-power entries are 6,000 rpm and 7.5 kW, each configuration-dependent. Its published 2,050 × 1,600 × 1,950 mm external dimensions are not an installation drawing or the additional occupied space for access and ancillary equipment.
Keep the technical record separate from transaction availability.
The current manufacturer material identifies 浙江金火科技实业有限公司. The US Treasury's SDN dataset reviewed on 8 October 2026 names Zhejiang GFIR Technology and Industrial Co Ltd under the RUSSIA-EO14024 programme and records identifier 91330183759536548T. This is a named entity restriction record, not a statement about machining accuracy or product certification.
The seven original technical URLs remain available for reference. CNCVerified's factory-specific transaction services remain unavailable for this record. Current technical tables do not resolve that restriction or constitute a transaction clearance.
