Precision clamping chucks
Applications
Koch stainless steel chucks are especially suitable for applications where low clamping forces, but high precision and small size are required:
metrology
measurement of gearbox shafts
measurement of spindles
testing of needles and cannulas
electrical discharge machining
wire erosion with rotating spindle
usage as work piece holder in dividing machines
underwater applications
ultrasonic testing
ultrasound cleaning
laser applications
laser marking
laser welding
All stainless steel manual chucks are suitable for vacuum and underwater use and can be supplied with special greases for these applications on request.
Benefits
Koch stainless steel chucks offer many advantages over normal chucks:
Superior precision
All chucks in the DBF series have excellent concentricity (guaranteed: ≤20µm, typical ≈10µm) and a high clamping repeatability (5µm).
small size
Koch chucks are much smaller than other chucks with comparable clamping range.
100% stainless
All chucks are completely made of stainless materials. The chucks therefore do not require any corrosion protection and can also be used under water.
Simple assembly / disassembly
The chucks of the DBF series consist of few components and are accordingly quick to disassemble and assemble.
Easy disassembly / assembly of DBF63 (mounted on an adaptor for a Hirschmann zero-point clamping system
No tools required
All chucks of the DBF series can be conveniently adjusted by hand by turning the clamping ring. No key or similar tools are required.
