XT40-1-E BT40 ATC + through-spindle coolant
A rear-mounted BT40 automatic tool-change configuration with a through-spindle coolant path for applications that need deep-hole cooling and chip evacuation.
XT40-1-E-BT40-MB-CTS combines a rear-mounted BT40 motorized spindle and automatic tool change with through-spindle coolant. Confirm the tool, seal, pressure, flow, plumbing, controls and machine envelope as one system.
Application fit
Start with the workpiece and process. The model name is only a starting point; final selection follows the tooling, load and real machine layout.
Deep-hole cooling
Route coolant through a compatible tool and spindle path when external delivery is not enough.
Chip evacuation
Use the coolant path to support chip control, while confirming tool and process compatibility.
Concentrated machining
Combine BT40 tooling, automatic tool change and coolant delivery in one machine module.
Controlled integration
Coordinate seals, pressure, flow, drainage, sensors, guarding and service access before release.
Published selection data
| Model platform | XT40-1 BT40 motorized boring and milling spindle head with automatic tool change |
|---|---|
| Spindle interface | BT40, 7:24 taper |
| Tool change | Automatic tool change with an unclamping cylinder; magazine, gripper and control sequence are application dependent |
| Servo spindle motor reference | 3.7 kW / 23.6 N·m is labeled on the CTS assembly drawing; this is a pictured configuration, not a universal motor specification |
| CTS motor range | No separate CTS motor-range table is printed on the cited CTS page; confirm the selected motor and transmission |
| CTS motor speed | Rated and maximum motor speed must be confirmed for the selected CTS build; the adjacent ATC table is not a CTS specification |
| Spindle-head assembly weight | 95 kg is shown for the pictured CTS assembly; actual assembly weight depends on configuration |
| Published roundness | ≤ 0.004 mm; confirm measurement point, method and acceptance conditions |
| Published temperature rise | ≤ 20°C under the conditions represented by the published data |
| Coolant option | Through-spindle coolant (CTS/TSC) for deep-hole cooling and chip evacuation; pressure and flow must be confirmed |
| Integration file | Request the matching BT40, motor, ATC and coolant interface drawing before integration |
| Series spindle speed reference | 2,500 / 4,500 / 7,000 rpm; 7,000 rpm requires the listed NSK-bearing configuration. Confirm the complete variant and drive ratio |
| Series bearing reference | 2,500 rpm: NN3011/234411BM1 with 7010AC/DB; 4,500 / 7,000 rpm: 7011AC/TBT with 7010AC/DB |
CTS/TSC requires a compatible tool, spindle sealing, coolant supply, drainage and machine control. No generic pressure or flow value is promised here; confirm the complete coolant interface in the approved drawing and quotation.

Cutting load, finish, accuracy and duty-cycle requirements.
Mounting drawing, center height, envelope, orientation and control.
XT40-1-E-BT40-MB-CTS selection questions
Confirm these items before the drawing and quotation are approved.
What is included in the BT40 ATC configuration?
The published configuration shows a BT40 7:24 spindle, motor drive and automatic tool-change hardware with an unclamping cylinder. The magazine, gripper, sensors and control sequence must be matched to the machine.
Can the ATC cycle time be specified from the product page?
Cycle time depends on the magazine, tool mass, control sequence, spindle orientation and machine motion. Request a complete cycle review instead of using a generic time claim.
What is the benefit of through-spindle coolant?
Through-spindle coolant can carry coolant through a compatible tool and spindle path for deep-hole cooling and chip evacuation. Confirm tool, seal, pressure, flow and machine-interface requirements in the approved design.
Is the 3.7 kW / 23.6 Nm motor value universal?
It is a reference shown in the published CTS configuration image, not a universal promise for every build. Confirm the motor, torque curve, drive, pulley ratio and duty cycle for the order.
What information is needed for an ATC quotation?
Send the tool list, holder standard, magazine capacity, tool mass and length, change sequence, spindle orientation, coolant requirement, machine envelope and destination country.
Catalog source and configuration limits
JNYO product catalog, printed pages 13–14 (PDF page 10); ATC and CTS drawings, printed pages 15–16 (PDF page 11); Chinese edition, approximately 74 MB.
Spindle speed and motor speed are separate values; output speed depends on the selected drive ratio and complete configuration. Catalog roundness and temperature rise require defined measurement and operating conditions and are not guarantees of workpiece accuracy. HP and kW retain the source units.
The website groups this variant under the enhanced E series; the source drawing is labeled XT40-1-BT40-C-MB. Match the complete tool interface, clamping system and configuration list rather than relying on the shortened series name.
NT40 rear-drawbar and BT40 automatic tool-change arrangements are shown separately. ATC does not by itself include through-spindle coolant; CTS also requires compatible tooling, a coolant passage, rotary union, supply, filtration and control interfaces.
Move from product review to machine integration.
Use the model as a starting point. The approved dimensional drawing and configuration record remain the final integration reference.
Confirm mounting faces, center height, spindle interface and machine envelope.
