SZGH-CNC1000TDc-3 — High-Performance 3-Axis CNC Lathe & Turning Center Controller

The SZGH-CNC1000TDc-3 is a high-performance 3-axis CNC controller purpose-built for CNC lathes, turning centers, grinding machines, and specialized automation equipment. Designed as the step-up solution for builders and retrofitters who have outgrown basic 2-axis turning controllers, the TDc-3 adds C-axis (spindle servo positioning), EtherCAT and Powerlink bus servo support, four Automatic Tool Changer (ATC) turret configurations, and dual threading cycle modes — giving machine builders and job shops the control architecture needed for live tooling, servo turret integration, and high-precision interpolated threading. The controller ships with an 8.4-inch 800×600 full-color LCD, full English-language interface, open Programmable Logic Controller (PLC), and USB + RS232 Data Numerical Control (DNC) file transfer. Factory-direct from SZGH (Shenzhen Guanhong Automation Co., Ltd.), CE certified, with a 2-year warranty and 24-hour one-to-one engineer support.

When to Choose the TDc-3 Over a Basic 2-Axis Controller

Your machine uses a servo turret or special turret. Servo and special-configuration turrets require servo-driven positioning that a standard 2-axis controller cannot coordinate. The TDc-3 natively supports servo turret and special turret ATC types, handling tool-change sequencing with the precision servo positioning those mechanisms demand.
You need C-axis (spindle servo positioning) for live tooling or milling on a turning center. C-axis turns the spindle into a controlled rotary positioning axis via the M800 command, enabling driven tool operations — milling, drilling off-center, and contour turning — directly on the lathe. This is the defining feature of a turning center controller vs. a plain lathe controller.
Your servo drives use EtherCAT or Powerlink bus communication. Modern bus-servo drives from major international manufacturers communicate over EtherCAT or Powerlink protocols rather than traditional step/direction pulse trains. The TDc-3 supports both bus types for feeding axes, providing deterministic timing and faster servo response that translates to better surface finish and more accurate thread profiles.
You need automatic tool setting or workpiece probing integrated into the CNC cycle. The TDc-3 includes built-in scanning function, auto tool setter (ATL), and probe support — so tool length measurement and workpiece reference setting happen inside the CNC program rather than as manual setup steps.

For basic 2-axis turning with standard ATC, see the SZGH-CNC1000TDc-2.

ATC: Four Turret Types Supported

The TDc-3 supports four turret configurations — select the type that matches your machine's tool-change hardware.

Turret Type	Description
Electric Turret	Standard electrically indexed rotary turret — the most common configuration on CNC lathes
Binary Turret	Binary-coded tool position detection turret, typically used on older or custom machine designs
Servo Turret	Servo-motor-driven precision turret — high-speed indexing with closed-loop position control
Special Turret	Custom or non-standard turret configurations for specialized machine architectures

Servo turret configuration delivers the highest repeat accuracy and fastest index times.

Threading Modes

Two threading cycle modes cover the full range of lathe threading applications.

Mode	Description
Following Mode	Spindle encoder-following threading — the controller reads the spindle encoder in real time and synchronizes the Z-axis feed to cut standard parallel, taper, and multi-start threads. This is the standard threading method for the majority of CNC lathe work.
Interpolate Mode	Interpolated threading cycle — the controller generates the thread path by interpolating axis motion, enabling complex thread forms and profiles that require coordinated axis movement beyond simple encoder following.

Following Mode handles virtually all standard threading requirements. Interpolate Mode is the right choice when thread geometry requires precise axis coordination — such as variable-pitch threads or threading cycles integrated with C-axis motion.

C-Axis & Spindle Control

C-axis support (spindle servo positioning via M800) is what separates a turning center controller from a plain lathe controller. When a servo drive is connected to the spindle, the TDc-3 can command the spindle as a controlled rotary positioning axis — enabling spindle indexing for part loading, rigid tapping, and live tooling operations such as off-center drilling and milling on the part face or OD while still in the lathe chuck. Dual analog outputs (0–10 V, two independent channels) support two-spindle configurations — such as main spindle and sub-spindle lathes — within a single controller.

Servo Bus Support

In addition to standard stepper and incremental/absolute encoder servo systems, the TDc-3 supports EtherCAT and Powerlink bus servo systems on all feeding axes. EtherCAT-connected drives communicate over a real-time industrial Ethernet protocol with deterministic cycle timing — typically 1 ms or less — which means the controller and drives stay perfectly synchronized even during high-speed threading passes and C-axis live tool paths where timing errors would create surface or pitch defects. This makes the TDc-3 compatible with modern bus-servo drives from major international manufacturers, allowing machine builders to specify high-end drives without changing the CNC controller platform.
