10/2019 • Issue 21Machining Titanium: An article by WIKUS
"Band sawing techniques for titanium are no more difficult than those for other high performance metals; for instance the austenitic stainless steels.
Reasonable production rates and excellent surface finish are readily attainable on sawed parts, provided some unique characteristics of titanium are taken into account. These characteristics are:
• The unusual chip-forming tendency and low thermal conductivity of titanium tends to cause a build-up of heat on the edge and face of cutting tools.
• The reactivity of titanium with cutting tools contributes to seizing, galling, abrasion and pick up on cutting edges and faces.
• The low elastic modulus of titanium permits greater deflections of work pieces and, therefore, may require proper backup.
Machining conditions can be selected which minimize or circumvent the adverse effects of these characteristics of titanium, thereby allowing good tool life at acceptable production rates."
USE LOW CUTTING SPEEDS
Tool tip temperature is strongly affected by cutting speed. A low cutting speed helps minimize tool edge temperature and maximize tool life. Lower speeds are required for titanium alloys such as Ti-6Al-4V than for unalloyed titanium.
MAINTAIN HIGH FEED RATES AND CONSISTANT DECENT RATES
Tool temperature is affected less by feed rate than by speed. Therefore, use the highest rate of feed consistent with good practice. The depth of cut should be greater than the work hardened layer resulting from the previous cut.
USE A GENEROUS QUANTITY OF CUTTING FLUID
Coolant carries away heat in addition to washing away chips and reducing cutting forces, thereby improving tool life.
MAINTAIN SHARP TOOLS
Tool wear results in build-up of metal on cutting edges and causes poor surface finish, tearing and deflection of the work piece.
NEVER STOP FEEDING WHILE TOOL AND WORK ARE IN MOVING CONTACT
Permitting a blade to dwell in moving contact with titanium causes work hardening and promotes smearing, galling, and seizing, which may lead to total tool breakdown.
USE RIGID SETUPS
Rigidity of the blade (proper blade tension) and workpiece (secure clamping) ensures a controlled depth of cut and reduce vibration
TOOL MATERIALS
Cutting tools for titanium require abrasion resistance and adequate hot hardness. Carbide tools (such as Grades C-2 and C- 3), where feasible, will optimize production rates. The general-purpose high speed tool steels (such as Grades M1, M2, M7, and M10) are often suitable for machining titanium. However, best results are generally obtained with more highly alloyed grades (such as M42, M51 and X3000 series).
CUTTING FLUIDS
Correct use of coolants during sawing operations on titanium will greatly increase the blades tool life. Chemically active cutting fluids transfer heat efficiently and reduce cutting forces between tooth tip and workpiece. The result is prolonged blade life. Large quantities of cutting fluid are needed to keep the titanium workpiece and the tooth tips cool during the sawing operation. Water base fluids are more efficient than oils. A weak solution of rust inhibitor and/ or water-soluble oil (5 to 10 percent) is the most practical fluid for bandsawing operations running higher cutting speeds. Slow speed and complex operations may require chlorinated or sulfurized oils to minimize frictional forces and reduce the galling and seizing tendency of titanium. Best blade life in intermediate speed operations may be achieved by utilizing a good coolant containing a chemically active additive.

Bandsaw Blade Plastic Strip Capping Machine
Saw Systems has invested in a machine to directly benefit our customers! This Capping Machine was an investment to work hand in hand with our customers, along with the safety of both our staff and customers. This machine directly protects the teeth of the blade. It does this by the safety features which are programmed in, to provide safer installation of the saw.
Shown in the media, is how the machine operates to safely do its job while protecting the blade as well as the user. The outcome is a sealed blade, making it easier to handle the blade, while simultaneously keeping the blade protected.
Some key details:
• 1"-3" Capacity
• Unlimited Length
• All Tooth Pitches
o Protects operator from sharp teeth handling and installing band on machine.
o Protects the teeth during installation from damage.
o Easy removal.
o Made from recyclable materials.

Back to School Drive
Saw Systems teamed up with one of our employee's (Amanda Jacobs) sister, Erica Ward Cherry, at Family Promise of Summit County. Family Promise is a non-profit organization that works to keep families together and reduce homelessness through programs including: Rental Assistance, Utility Support, Housing Location, Transportation and Temporary Hotel Stays.
This organization was chosen by Saw Systems because it not only helps homeless families throughout a time of struggle, but it is right here in our own community. It started when Founder Karen Olson was in her town and sat down with a homeless woman, which she had bought a sandwich for. She then started delivering food with her two children to homeless people regularly. In 1986, began the first connection and Karen brought together both people who were in need and people who wanted to help. In 1988, the network went national, with much more attention and awareness and Interfaith Hospitality Network came to light in more people’s eyes. In 1992, President Bush realized what such a help this was and gave Family Promise a title as one of the most beneficial agencies in the country. In 2004, the 100th Affiliate came about and expanded into Georgia, in numerous types of living environments, whether it be cities or rural communities. In 2013, 4-Star Charity recognized Family Promise as a 4-star rating overall with everything they do and how they handle what they do, as well as celebrating 25 years of helping others.
Today, Family Promise continues helps families in need, and asks its community for help. Saw Systems saw this and realized how good of an opportunity it would be to give back to its community this way. We donated over $1,000 worth of school supplies and donations with the help of our staff, friends, and family. We look forward to working with Family Promise again in the future.
