A Vertical Bridge Mill Provides Big Opportunities

Seeing your company as a boring-mill shop is a problem when only 20 percent of your jobs are actually boring-mill related. It’s also a problem to have the space and potential to produce large parts when you only win 6 to 14 percent of the large-part jobs you quote.

When Paul Schlatter established Napoleon Machine in 2010, the facility and machines he leased hadn’t been used in years. The machines themselves hadn’t been updated since 1996. In 2011, Mr. Schlatter brough on current president and owner Keven Febrey to lead shopfloor operations and strategic planning for the company. To remake the old job shop into a success, Mr. Febrey basically had to start from scratch.

“The biggest hurdle was the equipment itself,” he says. The facility’s size gave it the possibility of large-parts machining, but the outdated equipment was holding it back, keeping it from winning an adequate number of boring-mill-related jobs and large-part jobs. And for the large-part jobs it did win, setup times were between four and eight hours.

After investing in a Toyoda LB63324M mill with a vertical bridge, right-angle head, through-tool coolant and a 60-tool-capacity ATC, the company hit the ground running. The Toyoda made a solid impact on the shop floor in three ways:

  1. The right-angle head reduced setup times and improved part quality by increasing machining capabilities.
  2. It enabled the company to run repeat parts and processes.
  3. It reduced the shop’s run time per machined component by 49 percent on large-part projects.

While it used to win between 6 and 14 percent of its large-part jobs it quoted each year, these factors have enabled Napoleon to win 52 percent of the work quoted on its Toyoda bridge mill. It has also helped the company begin a transition in the type of work or the mix of work it can do.

  • Rigid Tapping--Sometimes You Need A Little Float

    One of the most common methods of tapping in use today on CNC machines is 'rigid tapping' or 'synchronous feed tapping.' A rigid tapping cycle synchronizes the machine spindle rotation and feed to match a specific thread pitch. Since the feed into the hole is synchronized, in theory a solid holder without any tension-compression can be used.

  • Choose The Best Drill Point Geometry

    The more common twist drill point geometries often are not the best for the job at hand. By choosing the best point for the material being drilled, it is possible to achieve better tool life, hole geometry, precision, and productivity.

  • Successful Application Of Ceramic Inserts

    Applying ceramic inserts is not a simple substitution of one cutting tool material for another. There are significant process considerations that shops should examine carefully in order to realize performance and tool life expectations from ceramic inserts. Here's a look at some of the ways they are used.
