Why RTCP Matters for 4-Axis Milling

RTCP (Rotary Tool Center Point) is a critical feature that allows the CNC controller to compensate for the tool's actual center position during rotary axis movements — rather than just controlling the machine's mechanical pivot point. This means:

✅ More accurate surface finishes on angled and curved workpieces
✅ Simplified programming — program the part geometry, not the machine kinematics
✅ Reduced scrap rates on complex 4-axis parts

Most controllers in this price range do NOT offer RTCP. The GH-1000MC-4 gives you this advanced capability as standard.

Rigid Tapping: Two Modes for Maximum Flexibility

The GH-1000MC-4 supports rigid tapping in both Following Mode and Interpolate Mode, ensuring perfect spindle-to-axis synchronization at the exact thread pitch. This eliminates the need for tension/compression tap holders and delivers:

Consistent thread quality at high speeds
Reduced cycle times vs. floating tap holders
Compatibility with all standard thread pitches

Frequently Asked Questions

What is the difference between this 4-axis controller and the 5-axis version?

The GH-1000MC-4 controls up to 4 simultaneous axes with RTCP support, ideal for 4-axis milling and indexing applications. If you need full 5-axis simultaneous machining, consider our GH-1000MC-5 5-Axis Controller.

Does this controller support RTCP for 4-axis machining?

Yes. The GH-1000MC-4 includes RTCP (Rotary Tool Center Point) mode as a standard feature, enabling accurate tool-center control during rotary axis movements.

What servo motors are compatible?

The controller supports Pulse+Direction, AB Phase, and 0~10V analog output — compatible with Delta, Yaskawa, Mitsubishi, Panasonic, and most other servo brands.

Can I use this for a CNC retrofit project?

Absolutely. The 36×36 configurable I/O, universal power supply (100-240VAC), and multiple position control modes make this controller ideal for retrofitting older manual or CNC machines.
