Shrink-fit and hydraulic holders are both useful in low clearance, tight work envelopes found in moldmaking and multi-axis machining applications. When deciding which one to use, their differences will guide your choice. Here are some of the fundamental contrasts to help you decide which holder type is best for your work.
Aerospace is unique among industries in its thirst for component accuracy with ‘blemish-free’ precision. Unlike any other industry, anything that goes into the air has to be on spec, as the smallest imperfection in machining can adversely affect flight safety.
As lathes and turning machines pivot toward quick-change tooling models from traditional stick tools, tool presetters present benefits of keeping chips flying while reducing human error and increasing precision.
Micromachining, cutting where the volume of chips produced with each tool path is very small, is not a high-speed operation in relation to chip load per tooth. Rather, it involves a high spindle speed due to cutter diameter. The part may be physically larger, but details of the part require ultra-small profiles achieved only by micromachining. In other words, micromachining is not limited in scope to only miniature parts.
As cutting tool manufacturers increase the recommended operating conditions for their products, users achieve the desired result: shorter cycle times on existing machine tools.
