BIG DAISHOWA introduces the EWN & EWD Smart Damper - precision boring heads with a patented damping system to eliminate vibration in deep-hole finish boring.
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.
Here are some insights into the extra care and know-how needed to achieve success and build a successful reputation as a reliable supplier of micro machined parts.
BIG DAISHOWA has introduced the new, large diameter Kaiser 318 Series - a complete tooling system supporting a variety of aluminum and steel components optimized for twin cutter rough boring, precision finish boring and precision OD turning operations.
While the latest machine tool technology may go a long way towards eliminating vibration and chatter, adding a new one may not be realistic. Luckily, there are less disruptive options that can make positive impacts on vibration without breaking the bank.
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 chances of a tool slipping or pulling out in its holder during work is increasing. Here are some insights to help you select the proper holder for your work.
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.
Tool presetters are used to measure offsets offline to keep machine tools running. They quickly pay for themselves by reducing downtime on machine spindles.
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.
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.
