Video: The Impact of a Horizontal Machining Center
A small shop describes the efficiency gains it is seeing now that it has a horizontal machining center instead of solely verticals. One of the shop’s leaders talks through processing of parts then and now.
Tri-State Tool Grinding is a Cincinnati, Ohio, shop that, along with the tool grinding in its name, also does general CNC machining. For this latter work, the shop recently made a move many small shops contemplate: the jump from vertical to horizontal machining.
For the shop’s first HMC, it invested in an a61nx from Makino. In the video above, Quality Manager Michael Newcomb describes parts that were formerly machined using verticals, and how those same parts are now machined more efficiently (thanks to fewer setups) on the horizontal machine. He also describes the shop’s use of Mastercam for programming these jobs.
Fast CNC processing and high-pressure coolant contribute to removing metal at dramatic rates. But what should a shop know about cutting tools in high speed machining?
When this aerospace job shop settled on machining tungsten alloys and other heavy metals as its specialty, it had to have a machine tool, cutting tools, workholding and process know-how to succeed.
The recipe for best results is simple: Start with a rigid machine, add a high pressure through-the-spindle coolant system, then combine these with the right drill geometry plus the right speeds and feeds.
