Size: ER25x4
ER25x4 ER Collet Clamp Fixture is a workholding fixture for securing compatible 4 mm shanks with an ER25 collet system. Its purpose is to keep the tool or workpiece aligned while the spindle or fixture applies controlled clamping force.
ER25x4 ER Collet Clamp Fixture Overview
Before ordering, confirm the ER25 interface, 4 mm nominal shank size, fixture mounting method, available clearance and the machine or holder drawing. Collet fixtures depend on correct seating and concentric contact; the title specification should be matched against the complete product dimensions rather than used alone.
Key Selection Points
- Match the ER25 collet system and nut or clamping interface.
- Confirm the 4 mm shank diameter and usable clamping length.
- Check mounting holes, locating surfaces, height and spindle clearance.
- Use a clean, undamaged collet and compatible tightening tool.
- Verify that the fixture supports the expected cutting forces and workpiece size.
Application and Setup Guidance
Use the ER25x4 ER Collet Clamp Fixture for compatible CNC routing, milling, drilling or tool-holding setups. Clean the taper, collet, nut and fixture seats before assembly. Insert the shank to the recommended depth, tighten evenly with the correct wrench and check runout before machining. Make a conservative test pass and recheck the setup after the first cut.
Fixture Setup Checklist
- Inspect the collet, nut, fixture and shank for burrs or damage.
- Clean mating surfaces and remove chips from the bore.
- Confirm full collet engagement without bottoming the shank.
- Check toolpath, spindle travel and surrounding hardware clearance.
- Verify clamping force and runout before production.
- Stop immediately if the tool, fixture or workpiece moves.
Safety and Maintenance
Use the ER25x4 ER Collet Clamp Fixture only with compatible equipment and follow the machine manufacturer instructions. Keep hands clear of moving parts, secure the workpiece and wear suitable eye, hearing and respiratory protection. Review OSHA machine guarding guidance for general safeguarding principles. For help confirming the interface, contact JEEFOO Tools with drawings and photographs.
ER25x4 ER Collet Clamp Fixture FAQ
What does ER25x4 mean?
It identifies an ER25 collet clamp fixture intended for a nominal 4 mm shank. Confirm the full interface and dimensional drawing before use.
How do I confirm compatibility?
Compare the collet series, shank diameter, mounting pattern, clamping length, clearances and machine interface with the fixture drawing.
How can I improve repeatability?
Use clean reference surfaces, a correctly seated collet, even tightening, verified runout and a documented setup procedure.
When should the fixture be replaced?
Replace it when the bore, threads, locating faces or clamping components are worn or damaged enough to reduce secure and repeatable holding.
For an accurate replacement request, quote ER25x4 ER Collet Clamp Fixture with the machine, collet and mounting details.
