Much of the mechanics of chip formation during high speed machining involves heat. Relative to the material being cut during machining operations, a lot of energy is being transferred to the work piece - and that energy converts to heat.
In the recent blog article "Machining Intelligently the Green Way", The Canadian Metalworking Magazine takes notice of the SPINJET, coolant-driven HSM spindle, as a greener alternative. Marketed under the trade names SPINJET and Typhoon, this innovative, eco-friendly high speed spindle increaser really does help promote a greener way of machining by utilizing the machine tool’s existing coolant supply, driven by a high pressure pump; creating an independent, internal energy source to rotate the spindle's turbine.
High speed steel (HSS) tools and flood coolant have traditionally combined for reliable and cost-effective machining processes. However, when a machining giant like Haas Automation, Inc., starts to transition from HSS and flood coolant to carbide tools and through-spindle coolant, the manufacturing world takes notice. In a recent video, two representatives from Haas Automation demonstrated the advantages of through-spindle coolant over flood coolant.
As new technology emerges, many companies are rethinking manufacturing practices that have been established for decades. Staying on top of the latest news and tech trends can help you maintain a competitive edge in your market. This edition of The Manufacturing Mix highlights some of the biggest news in November 2015 to help you get out ahead of new technology trends.
While small milling and drilling processes can seem like a minor piece of the massive manufacturing projects taking place in the medical and aerospace industries, these small machining processes are often where you lose the most production time. When the Matimop Eureka R&D network recognized this issue, they started looking into ways to boost efficiency without revamping their entire network of CNC machines. After researching coolant-driven spindle speed increasers, it became clear that they could rely on this solution to boost machining RPMs without sacrificing precision or accuracy. In fact, they found that working at higher speeds could actually improve quality in many key cutting applications.
For many machine shops, water is an essential part of the coolant mixture for more balanced lubricity and cooling capabilities. However, introducing water to your machining environment changes your maintenance requirements. If you aren’t on top of coolant quality, you risk allowing microorganisms into your cutting processes.
The days of old-school machine-driven spindles for high-speed applications are coming to an end. As throughput demands increase, bulky machine-driven spindle solutions simply can’t keep up. Because mechanical heads are large, require the installation of a stop block and can’t be indexed where multi-position machining is required, CNC machine builders are looking for more efficient ways to speed up their finishing and semi-finishing processes.
