While all spindle platforms (30T, 40T, & 50T) of vertical machining centers (VMCs) are capable of the vast majority of machining operations, there are major differences that exist between them that can make a 30-taper a better choice for certain applications. The best way to maximize profitability is to determine the best platform for each machined part. When hunting for an additional machine, it may be time to diversify your lineup.
Here are some factors to consider that may warrant a 30-taper compact machining center over a more traditional VMC:
At their conception, 30-taper compact machining centers were specifically designed for secondary operations, such as high-speed drilling and tapping. The 30-taper spindle is optimized for these operations, allowing it to operate at much faster speeds & feeds than a traditional VMC. Recently, these compact machining centers have been designed to be more rigid and handle more demanding operations, making them a more suitable platform for smaller, complex parts of all materials.
When it comes to smaller parts, traditional VMCs can encounter bottlenecks and increased cycle times since more powerful configurations yield slower movement. This is direct to your overall profit and efficiency on the shop floor. Compact VMCs offer faster tool-change times and rapid traverse speeds, which reduce non-cutting time when machining. This allows you to produce more parts on the 30-taper and free up your 40/50-tapers for your larger machined parts.
Ease of use and reduced set-up times
Even though all CNC VMCs are easier to use due to modern advances of the CNC controller, CAD/CAM software, and conversational software embedded in the CNC controller, the Drill/Tap centers often have advantages ingrained since their inception. For example, ergonomics for safety and ease of use, quick-load tool changers and palletized systems that allow for greater throughput while the operator can load/unload during the machining cycle. Compact VMCs often come equipped for modern convenience devices that aid in the reduction of setup time, such as spindle probes, tool setters and tool breakage detection to name a few.
While compact machining centers can be more expensive than lower-end traditional VMCs, they are often more cost-effective in the long run because they are optimized for high-speed machining operations. Diversifying your lineup can help you save more money by reducing non-cutting time of your 40/50-taper VMCs, saving floorspace and energy usage. This lets you complete more jobs in less time, which can help you increase productivity and profitability over time.
Overall, if you manufacture smaller or more complex parts, a drill/tap center may be a better choice to add to your machine lineup than a standard VMC. It can help you complete jobs more quickly and accurately, free up your larger VMCs for more traditional operations and ultimately increase your bottom line.
