The DMS35 Machine:

The EMMS of BCI is the first in North America to successfuly
install and use DMG’s Ultrasonic machining technology, the
DMS35.
|
Developed by Sauer & Company, (Stipshausen, Germany) the DMG DMS35
Ultrasonic machine’s integrated Siemens 840D power line allows for
maximum performance throughout 4-axis applications through process
monitoring by way of ADR and ACC that automatically adjust the machine’s
rate of movement as it machines.
How Ultrasonic Technology Works:
The machine uses, and then converts, a high frequency electrical
signal into an oscillating motion through electrically polarized
motors that are amplified by a booster. This process causes the
diamond-coated cutting tool to expand and contract at 20 kHz or
20 000 cycles per second while at the same time, rotating at speeds
between 20 and 6000 rpm and up to 60 000 rpm on optional spindles.
Cutting then takes place at the highest point of amplitude or expansion
of the tool. Machining is done wet using low concentration water
based synthetic coolant that floods the work piece, center of the
tool, and machining area. As the diamond particles collide with
the work piece surface, the material is broken up and flushed away.

Benefits of Ultrasonic Technology:
 |

Workspace of the DMS35
|
- Can machine engineered materials such as fired ceramics, (alumina,
and zirconia oxides), glass, silicon nitride, graphite, composite
materials and precious stones. Including work pieces made from
these advanced materials ranging in hardness from 55 Rc to just
softer than diamond.
- Can yield an increase in productivity three-to-five-fold as
compared to conventional machining methods and machine complex
geometries and tolerances so that post-fired materials can be
readily machined.
- Is capable of surface finishes of 0.2 micrometers and on average
readily produces roughness of 0.8 micrometers.
- Can machine solid-fired billets to high tolerances in a variety
of sizes, (127mm in diameter by 19.05mm in width) attain positional
tolerances of 0.0127mm, and controlled diameters as small as plus
or minus 0.005mm.
- Can reduce time-to-market and prototyping as machining begins
as soon as the piece of fired material is available.

Ultrasonic Technology and the Future:

As a result of the EMMS’s proactive approach to business
and its commitment to the advancement of the machining
industry, with this new technology on hand, the EMMS
is revamping the ceramics industry by the hour.

Many engineered materials are a challenge to machine.
Many parts or components can be difficult or costly to manufacture
because of short runs, close tolerances, processing and/or tooling
requirements.
Using ultrasonic technology these hurdles can be overcome. Unique
parts can be used in a range of unusual applications.
For instance, ceramic components are extremely hard and resist
wear. Many are also inert and can be used in a variety of situations
from the human body to insulators.
Ultrasonic precision machining sets the stage for new applications
with various advanced materials. The future of precision
machining is friendly with the arrival of ultrasonic technology
with optimum benefit going to the medical and space sciences, oil,
gas and nuclear industries.
BCI’s EMMS succeeds in using ultrasonic technology because the
EMMS has mastered all four of the critical success factors associated
with ultrasonic technology.
Critical success factors: Ultrasonic equipment, diamond-cutting
tools, engineered material knowledge and manufacturing technique.
They have the DMS35 ultrasonic machine, equipped with the Sauer
spindle that gives them extremely high accuracy and the ability
to manufacture components in advanced engineered materials.
They have the critical diamond cutting tools that when combined
with the Sauer K System on the spindle enable 100 percent of the
ultrasonic frequency to transfer directly to the tool.
They have the knowledge. The EMMS has over 40 years of combined
business and hands on highly skilled trades experience and a solid
understanding of the materials and how they machine.

Our Commitment
to You
We can provide you with an innovative solution or
alternate method of manufacturing to meet your engineered
materials requirements.
|
They have, and can effectively use and apply, the appropriate cutting
technique and/or methodology for cutting. Sound methodology, insightful
tooling and work holding combined with proven processes is key to
project successfulness, and even more so in the early project development
phase.
The Tandem (USB 12.2) sub spindle is an available option
for the DMS35 ultrasonic machine that the EMMS offers to its customers.
The sub spindle allows BCI’s EMMS to offer their clients the manufacturing
of holes ranging in diameter from 6mm down to 0.3mm at a maximum
of 12,000 RPM’s. It is equipped with high pressure through tool
coolant and a core ejector system.
This option is ideal for customers with a need to: drill high
precision holes within plus or minus .0254mm and 0.05 concentricity
and perpendicularity.
