A larger table does not solve every reach problem.
Kejie’s JIATIE catalogue spans engraving/milling, vertical machining, grinding, drilling and multi-axis equipment. For the three reviewed references, compare the loaded fixture and access to the critical feature first. JTVC-855P3 and JTVC-1166 provide different vertical work envelopes and loads; JTGK-1100i places the longer travel along Y, with a smaller load and different tool interface.
| Setup reference | JTVC-855P3 | JTVC-1166 | JTGK-1100i |
|---|---|---|---|
| X / Y / Z travel | 800 / 500 / 550 mm | 1100 / 650 / 600 mm | 500 / 1100 / 300 mm |
| Worktable | 1000 × 500 mm | 1200 × 650 mm | 500 × 1100 mm |
| Listed maximum workpiece height | 500 mm | 600 mm | 370 mm |
| Listed table load | 800 kg | 1100 kg | 300 kg |
| Published tool arrangement | BT40; 24-tool arm magazine | Short-nose BBT40 spindle | BBT-30 / BT30 catalogue reference |
| Question to resolve | Clamps, holder reach and 24-pocket allocation | Loaded height and distribution; compatible BBT40 tooling | Long-Y part/fixture orientation; fine-feature tooling and chip/coolant plan |
Swipe to compare the last model on a phone. Workpiece height is the manufacturer’s listed reference, not Z travel or spindle-nose clearance. Request the complete working-envelope drawing with the fixture, tool and safe change position.
Vertical machining: review the holder and the complete loaded fixture.
JTVC-855P3: map the 24 tools and clamps.
The model page describes three linear guide axes, a BT40 tool connection and a 24-tool arm magazine. The 800/500/550 mm travel, 1000 × 500 mm table and 800 kg load should be checked with the part, base plate and clamps together. Ask for the load distribution and centre-of-gravity conditions; the nominal table size does not prove that every feature remains accessible.
Send the longest holder and highest obstruction, together with roughing and finishing cuts. The reviewed page describes spindle cooling but does not give a model-specific speed or motor-duty table. Request the offered spindle curve, control, holder limits and pocket clearance rather than importing the engraving machine’s 24000 rpm entry.
JTVC-1166: use the extra space with a reach review.
The larger reference lists 1100/650/600 mm travel, a 1200 × 650 mm table, 600 mm maximum workpiece height and 1100 kg table load. The page describes a short-nose BBT40 spindle with forced cooling and automatic chip removal. Confirm the actual holder/stud compatibility, loaded fixture height and unobstructed tool-change position.
For a housing or mould setup, show the deepest bore, longest finish tool and datum transferred into a second clamping. Ask how the chosen conveyor and coolant arrangement handle your material. A larger machine body or listed load does not establish spindle torque, stable heavy cutting or a finished-part accuracy result.
JTGK-1100i: orient the long feature along the actual travel.
The Chinese catalogue calls this an engraving and milling machine; the English page calls it a CNC machining centre. Its 500/1100/300 mm X/Y/Z travel makes Y the longer direction. Orient the proposed part, datums and clamp rows in the process drawing; do not turn “1100” into an X travel or assume the entire 500 × 1100 mm table is a reachable finished-part envelope.
The February 2025 catalogue lists 7.2 kW / 24000 rpm, BBT-30 / BT30, 12 m/min rapid traverse and 10 m/min cutting feed. The power duty and spindle curve need confirmation. A small cutter’s runout, holder reach, engagement and material matter more to a fine feature than maximum speed alone. The 300 kg load includes the complete setup.
Keep fine milling, rotary options and graphite equipment separate.
The catalogue lists an automatic tool setter and spindle cooling among its standard accessories, with a fourth-axis rotary table among options. Agree the delivered configuration, axis/control and postprocessor; an optional table does not make the base reference a simultaneous five-axis machine.
Published positioning is 0.008 mm/300 mm and repeatability 0.005 mm. These are catalogue machine references, not a guarantee of the same tolerance or finish on an electrode, mould or released thin part. Graphite machines are a separate catalogue route: an electrode illustration does not establish dust extraction, sealing or suitability for dry graphite on JTGK-1100i. Specify the material and chip/dust-control process before selecting.
Choose the sample that exposes the buying risk.
Housing or loaded vertical setup
Trial the tallest clamp, deepest bore and longest holder on the quoted JTVC configuration. Include roughing, chip removal and finishing; inspect datum relationships after unclamping and after the planned second setup. Record loading and tool-change time separately from cutting.
Fine feature or electrode/mould surface
Trial the smallest critical feature, long-Y reach and required surface on the quoted JTGK tooling. Agree cutter/runout check, CAM programme, warm-up, measurement and surface method. Inspect after release; include tool wear, breakage detection and safe restart in the result.
Ask for serial-machine test records and an accepted sample programme. A gallery of application parts or inspection instruments does not prove your tolerance, material-specific process or cycle. Include the intended batch mix and intervention frequency when agreeing productive output.
Body references are 2580 × 2210 × 2750 mm / 4500 kg for JTVC-855P3; 2960 × 2750 × 2950 mm / 7500 kg for JTVC-1166; and 2050 × 3010 × 2380 mm / 4000 kg for JTGK-1100i. Obtain the delivered layout including door, conveyor, coolant, maintenance and loading access. The JTGK catalogue’s 3-phase AC380V ±5%, 50Hz reference must be reconciled with destination power.
Connect the brand, builder and actual support scope.
The Chinese official profile identifies 广东科杰技术股份有限公司 and JIATIE/佳铁 among its brands. Its older profile dates the JIATIE brand to 1998; that brand history is not a claim that every current legal entity or plant was registered in that year. A November 2024 Pengjiang Science and Technology Bureau report names the company and its participation in a drive/control technology project. That is dated external identity and research corroboration, not certification of these three machines.
The manufacturer describes development of CNC controls, motorised spindles, rotary tables and tool magazines, and publishes laser, ballbar, vibration and sample-inspection methods. Ask which components, control version and serial test records apply to the offered machine. General in-house capability does not determine every model’s delivered control or configuration.
Confirm the selling/manufacturing entities, assembly location and destination commissioning. Agree CAM/postprocessor validation, training, programme and parameter backups, spindle/toolchanger spares and warranty responsibility. Domestic service-network claims do not establish response time at your installation country. The wider grinding, graphite and multi-axis catalogue needs a separate model-specific review when that process is required.
Send the loaded setup and the critical feature.
Include the drawing, material/blank, datums and released tolerances, surface requirement, batch mix, loaded fixture height/size/mass, complete holders, longest reach and the critical roughing or fine-feature operation. Add destination power and access constraints.
Request a model/revision proposal, spindle/control and accessories list, fixture-reach check, sample programme and inspection plan through CNCVerified.
