Zero Nut
The return-to-zero nut locks the collet and allows fine adjustment of tool runout via six screws, ensuring high-precision machining.
Suitable for high-precision machining to improve machining quality.
- Dual functions: not only can it lock the collet, but it can also fine-tune the tool runout accuracy.
- Six-point adjustment design: There are six screws on the nut to fine-tune the tool runout and improve machining stability.
- Reduce tool runout: Even if the tool is extended, it can maintain high precision, suitable for tools such as hinges, drill bits, and milling cutters.
A total of 6 oil circuit screw holes
With AA grade collet
Steps for usage
STEP 1
Loosen and adjust the screws first.
STEP 2
Lock the cutting tool first, and then lock the side adjustment screw.
STEP 3
Measure the current runout accuracy of the tool that needs to be zeroed.
STEP 4
Adjust the runout accuracy of the tool by adjusting the side screw until the desired accuracy is achieved.
STEP 5
Done.
