So far, he's still right: no sensible CEO is going to get behind a serious investment in machining
capabilities for financial reasons.
Designs, builds, and repairs precision injection molds for thermoplastics and thermosets using CNC machining
. Also automatic molds and short-run tooling.
Because getting parts to the spindle and having the right tools available to do the cutting are key aspects of productive metal removal for horizontal machining
centers, Toyota Machinery USA (www.toyodausa.com) has developed the Flexible Pallet Automation (FPA) system and the Matrix Tool Magazine.
And the process of cutting a mold out of sand is sometimes more difficult than machining
metal, according to Reg Gustafson.
If you want a better production machine, then build one--that's more or less the approach that was taken by Haas Automation (Oxnard, CA; www.haascnc.com) in building the EC-630 horizontal machining
Another improvement area is environmental: the amount of air consumed during machining
is reduced 50%, a grease lube system reduces waste oil by 57%, and coolant life is boosted by 50% because there are no tramp oils from the linear guide lube system.
Using the FDM models, production of trim dies can begin without waiting for first-piece production, as can construction of fixtures for post-casting machining
and masks for surface finishing, if such operations are required.
It also takes on work from other foundries looking to outsource machining
Complete in-house capabilities utilizing CAD/CAM design and programming for 3-D surface modeling and CNC 3-D contour machining
. Mold repair and revision services.
* Take a high-level description of a part and automatically break down the machining
operations necessary to make it, then determine the required setups, fixturing and tools
Five more actual cases reveal that cast iron 'machining
' problems aren't necessarily foundry-related.
So they have developed a machining
module called the "Linear Tool Changer" (LTC) that reduces toolchange time to less than one second.
