Operating Instructions

Use the diagram from page 3 under this section. It visually shows the difference between Standard (Figure A) and Ramping (Figure B) entry and exit modes.

Operation Mode	1. Position	2. Preload	3. Feed	4. Stop	5. Retract
Standard – Figure A	Approach the tool without rotation	Compress spring and set depth	Feed with rotation	Stop rotation and feed	Retract upward vertically
Ramping – Figure B	Arc entry with rotation	Compress spring and set depth before feed	Feed with rotation	—	Arc exit with rotation

Ramping provides smoother engagement, reducing tool marks and improving surface finish quality.

Usage Guidelines

Approach the brush vertically and engage it with the workpiece
Avoid side contact, as it can damage the bristles
Do not let the tool drop into pockets
Do not contact protruding features
Ensure the floating mechanism can move freely at all times
Prevent lateral side loading on the brush or tool

Practical Recommendations

Apply preload before starting the cutting process
Maintain consistent spring engagement throughout machining
Proper setup improves both entry and exit surface quality
Stable operating conditions help achieve longer tool life and repeatable results

Precautions for Use

Ensure the collet and holder are securely tightened before operation
Confirm that the tool shank is properly clamped in the machine chuck
Always wear appropriate protective equipment
If the tool is not fully inserted, vibration may cause loosening, detachment, breakage, or injury
Use a chuck that matches the shank diameter correctly
Operate only with equipment capable of controlling rotational speed
Do not use through-spindle coolant
After extended use, reduced spring force may affect floating function, so check functionality before use
During machining, particles and dust may scatter, so use suitable extraction
Processing dust may be harmful to health
Perform a short test run before use
Stop operation immediately if vibration or abnormal behavior occurs
Do not exceed maximum rotational speed, depth of cut, or brush projection
