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.
BIG DAISHOWA has launched the HMCJ, a super-slim milling chuck with peripheral coolant supply, designed to support heavy-duty and finish end milling tasks with power and precision using Ø1/2” or Ø12mm cutters.
As cutting tool manufacturers increase the recommended operating conditions for their products, users achieve the desired result: shorter cycle times on existing machine tools.
The presetting machines available today are accurate, easy to use and provide closed-loop tool compensation on the CNC machine tool, saving significant time during job change-over.
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.
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.
Many machine shops lack objective criteria for making toolholder purchasing decisions & most are made by price alone. However they can improve runout significantly by using the right toolholders.
The precision and ruggedness of KAISER boring heads from BIG DAISHOWA deliver measurable performance advantages, significantly reducing finishing cost and cycle time.
Moldmakers hoping to avoid problems such as chatter, poor tool life and molds that fail quality control muster need to consider a variety of factors when selecting a long-reach toolholder.
If you purchase cheap dual contact tooling after being told by a supplier that it will work just as good as the original you risk unsatisfactory performance.
When that inevitable job arises that requires higher RPM output, operators are left with the choice of replacing the machine altogether to gain higher productivity, or looking into an attachment, like a spindle speeder, to close the RPM gap.
