Price estimate
We do not have a price for the Jingdiao JDGR400T that we can stand behind, so we show no number. Configuration, options and installation move the final price a long way: a quote is the reliable figure.
Overview
The Jingdiao JDGR400T is a 5-axis high-speed machining center built around torque more than speed. Its standard spindle is a 20,000 rpm HSK-A50 unit that the maker rates at 21.5Nm, fitted over an A/C rotary table of Ø400 mm (15.7 in) that carries 150 kg (331 lb). Travels are 450 mm (17.7 in) in X, 680 mm (26.8 in) in Y and 400 mm (15.7 in) in Z.
Jingdiao describes the JDGR400T as a precision type for drilling, milling and grinding of complex shapes in hardened metals above HRC 50, and states 2 ~ 10 μm machining accuracy. The reason it gives for the standard spindle is tool range: with that torque a large-diameter face mill can finish the big flat surfaces of a die, and the same spindle handles milling, grinding, drilling, boring and tapping. A coolant-through version is the option for deep holes and deep cavities. There is no small-taper precision spindle on the list, which is the clearest difference from the JDGR200T below it.
The long axis here is Y, at 680 mm (26.8 in), with the table tilting on A from -120° to 90° and rotating 360° on C. The data sheet lists 0.002 / 0.002 / 0.002 mm (X/Y/Z) positioning accuracy and 8 / 8 sec (A/C) on the rotary axes, with rotary rapids of 60 / 100 rpm (A/C). A direct-drive double-axis rotary table and a spindle and rotary table refrigerator are standard.
For batch production the maker lists a hydraulic fixture interface on the rotary table, an in-machine spray system working with a screw chip conveyor, and a scraper style chip conveyor, all as extras. The chain magazine holds 37 tools. Machine weight is 10,700 kg (23,589 lb).

Strengths & Limitations
Strengths
- Standard 20,000 rpm HSK-A50 spindle rated at 21.5Nm, enough for large-diameter face mills on die surfaces
- A/C table of Ø400 mm (15.7 in) with a 150 kg (331 lb) load
- Positioning accuracy of 0.002 / 0.002 / 0.002 mm (X/Y/Z) and 8 / 8 sec (A/C)
- Direct-drive double-axis rotary table with rapids of 60 / 100 rpm (A/C)
- Coolant through spindle available for deep holes and deep cavities
Limitations
- Only HSK-A50 spindles at 20,000 rpm are listed; there is no high-speed small-taper option for fine mirror finishing
- One magazine size, a chain type with 37 tools
- X travel of 450 mm (17.7 in) is shorter than the 500 mm (19.7 in) of the smaller JDGR200T
- The hydraulic fixture interface and scraper style chip conveyor for batch work are optional

Frequently Asked Questions
01
The rotary table is Ø400 mm (15.7 in) and the maximum workload is 150 kg (331 lb). Linear travels are 450 mm (17.7 in) in X, 680 mm (26.8 in) in Y and 400 mm (15.7 in) in Z, with the A axis tilting from -120° to 90° and the C axis rotating 360°.
02
The standard spindle is a Jingdiao high-speed precision spindle running to 20,000 rpm with an HSK-A50 tool holder; the maker states a torque of 21.5Nm for it. A coolant through spindle with the same speed and taper is optional and is recommended by the maker for deep hole and deep cavity processing.
03
The data sheet lists 0.002 / 0.002 / 0.002 mm (X/Y/Z) positioning accuracy and 0.0018 / 0.0018 / 0.0018 mm repeatability for the linear axes, and 8 / 8 sec (A/C) positioning with 5 / 5 sec (A/C) repeatability for the rotary axes. The stated machining accuracy on parts is 2 ~ 10 μm.
04
It is larger and built for heavier tools. The JDGR400T has a Ø400 mm (15.7 in) table for 150 kg (331 lb) and lists only 20,000 rpm HSK-A50 spindles. The JDGR300 has a Ø300 mm (11.8 in) table for 100 kg (220 lb) and can also take a 32,000 rpm HSK-E32 spindle for precision machining.
05
Jingdiao lists several items for batch work: an optional hydraulic fixture interface on the rotary table for rapid clamping, an in-machine spray system that works with the screw chip conveyor, and an optional scraper style chip conveyor that carries chips to a collecting trolley.
