For over 100 years, there have been many innovations and improvements made to the McKenzie Chip Separator but the basic premise of separating the parts from the chips without causing damage has remained the cornerstone. While efficiency, productivity and cost/benefit ratios have risen tremendously, today's machines have the distinctive look, toughness, and dependability of their predecessors. After all, while many changes have occurred in the industry, the basic heart of it hasn't. When making chips while making parts the McKenzie Chip Separators are there to separate one from the other in the most cost effective manner...
McKenzie Engineering Company
Founded in 1912 by William McKenzie, and passed on through his family over the years, it was
sold in 1998. In 2007, the company relocated to Maryville Tennessee, just south of Knoxville, and
is currently run by it's Vice President and
General Manager, Brian Bonamico. We currently
offer three basic platforms.
The MODEL B Chip Separator is very effective for smaller shops and departments producing parts under ½ inch in diameter and less than 1 inch long, such as that produced by Swiss type, Brown & Sharpe, and Davenport screw machines. Available now with either a flow control hopper similar to the floor models or the standard configuration without, the Model B can process from an average rate of 1.5 cubic feet per hour to a maximum of 3 cubic feet per hour.
The MODEL E Chip Separator has been designed specifically
for use by jobbing type shops having from
five to twenty-five automatic screw machines
doing Swiss, Brown & Sharpe and/or the
smaller multiple spindle type work. It's
flow control hopper will handle parts ranging
in size from .040" to ¾"
diameter and from ¼" to 3½"
in length, at an average rate of 14 cubic
feet per hour to a maximum of 30 cubic feet
The MODEL L Chip Separator is designed to separate parts
ranging in size from .060" in diameter
and ¼" in length up to 2"
in diameter and 6" in length. The automatic
feed feature with a flow control hopper permits
efficient separation of parts from chips
at an average rate of 34 cubic feet per hour
to a maximum rate of 60 cubic feet per hour
(or 1 cubic foot per minute). This machine
is generally used to meet quantity production
requirements for parts produced by Brown
& Sharpe, Davenport or other multiple
spindle type screw machines producing larger
and/or heavier parts.
Using the basic machine as the starting point, each machine can be custom fitted to the individual customer and the parts that are being presented for separation. Improvements have been continually made but the ruggedness and dependability still remain, separating part from chips, profit from loss, year after year.
McKenzie Engineering Company's History:
As the screw machine trade developed, more applications were found, and the quantities of parts produced increased, the problem of separating the machined part from the chips became more and more of an issue. Various methods were employed but they exhibited a common deficiency. They just weren't fast enough to the degree of efficiency required. Then in 1912 William McKenzie founded the McKenzie Engineering Company, developed and marketed his chip separator for automatic screw machines. It featured the unique concept of using relative density and turbulent air flow as it's discriminating criteria, not employing screens or riddles, nor was it limited by any weight versus size relationships. The concept worked well and suddenly production was no longer measured by how many pieces a man could pluck from the tray or sift through a screen.
Fine tuning and refinements continued as more and more applications were found for these three
workhorses. Continuing shifts in the materials being machined, the constant rise in labor costs,
the tightening of tolerances, the tougher delivery schedules, and the use of more and more
automatic assembly machines all contributed to the pressures felt by manufacturers which in turn
has resulted in continued modifications and improvements as well as wider applications and
greater versatility to the family of McKenzie Dechippers.™
