SZGH-CNC1000TDc-4 — High-Performance 4-Axis CNC Lathe & Turning Center Controller

CNC1000TDc Series — Choosing the Right Model

The CNC1000TDc series covers entry-level to high-performance CNC lathe and turning center control. Use the table below to identify the right model for your axis count and feature requirements.

Key Specifications

What Position Feedback Adds

Position feedback — also called position verification or actual position readback — means the controller continuously compares the commanded axis position with the actual encoder feedback in real time. If an axis deviates from its commanded position due to load variation, vibration, or servo lag, the system detects the discrepancy and compensates rather than continuing to machine on an incorrect trajectory. For precision turning centers, automated equipment, and any application where undetected axis error directly affects part quality or machine safety, position feedback is the primary technical reason to select the TDc-4 over the TDc-3.

What Absolute Encoder Support Adds

Absolute encoders retain the exact axis position in memory after the machine is powered down — no homing cycle is required when the machine is restarted. For turning centers running production shifts, eliminating the homing sequence at every startup saves measurable setup time and removes a potential source of operator error.

Key Features

1. 4-axis control — X/Z plus two additional controlled axes for sub-spindle, Y-axis, tailstock servo, or rotary axis integration; supports configurations including X/Z/C/Y and X/Z/A/B

2. Position feedback — real-time closed-loop position verification on each axis; detects and compensates for axis deviation under load

3. Absolute encoder support — axis positions are retained after power-down; no re-homing required at machine startup

4. 2ms interpolation — high-speed interpolation cycle for smooth, precise axis motion and improved surface finish on turned and contoured features

5. Open PLC (editable online/offline) — customize machine logic, interlocks, and I/O sequences without proprietary software; accessible to your machine builders and maintenance engineers

6. USB DNC (Direct Numerical Control) + macro program — run large or complex programs directly from a USB flash drive; build custom fixed cycles using the macro programming environment to reduce per-part programming time

ATC, Threading & Spindle (Inherited from TDc Platform)

The TDc-4 inherits the full turret, threading, and spindle capability of the TDc platform:

• ATC (Automatic Tool Changer) support — compatible with four turret types: Electric, Binary, Servo, and Special; covers the full range of powered and non-powered turret configurations used on CNC lathes and turning centers

• Dual threading modes — Following Mode and Interpolate Mode; supports standard and complex thread forms including taper threading and variable-pitch threads

• Dual analog spindle (0–10V) — two independent analog spindle outputs for two-spindle turning center configurations (main spindle + sub-spindle)

See the SZGH-CNC1000TDc-3 for full turret and threading specification detail.

Applications

The SZGH-CNC1000TDc-4 suits any turning machine or automation cell that requires four independently controlled axes. Common applications:
