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.
Manufacturing miniature parts and features is not new. In the past, EDM and laser technologies were used to create these features. Although these technologies worked for low volume jobs, they are not practical for the high volume micro applications that are in demand today.
In-machine laser technology is touted by machine tool builders and distributors as the way of the future and an indispensable tool for machinists. Do you really need an offline presetter if you have in-machine lasers?
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.
The return on investment from digital boring comes from the time saved making adjustments on the spindle, as well as the increased adjustment accuracy.
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.
Tool management system (TMS) software & a tool presetter can accomplish both cutting cost and increases in productivity for a shop’s day-to-day activities.
By using digital technology and optimized indexable inserts, Schmauser Müller Metalltechnik has increased process reliability and efficiency in fine boring, as well as increased the lifetime of its tools by a factor of three.
The SPERONI ESSENTIA features a compact bench-top design, works with any brand of router tools and handle complex tool profiles in stone cutting with ease.
