Overview:
- This training provides an introduction to using and operating the TrimSaw 2 diamond cutting saw including:
- Blade Types
- Metal cutting blades
- Glass cutting blades
- Fixtures
- Safety
- PPE for saw
- Hazards
- Saw use
- Saw Maintenance
- Coolant tank cleaning/refill
- Blade Replacement
- The Trimsaw 2 uses 4, 5 or 6 inch diamond blades to make fine cuts in metals, glass, ceramics and PCBs. Specific blades for each material are available and should be changed before cutting new material. A variety of fixtures and guides are available with custom fixtures available for specific jobs (contact Dave Bothman or a Workshop Wizard for custom tooling). Spinning up to 3000 RPM the bottom of the blade is submerged in coolant to lubricate and cool the blade while in the cut. A blade splash guard and plexiglass cover reduce the amount of lubricant thrown by the blade.
Safety
- Eye protection should be warn at all times while operating the saw
- All guards and shields should be in place before turning the saw on
- Hands should be kept free and out of the way of the blade at all times
- Nitral (NOT RUBBER OR CLOTH) gloves should be warn when cutting specific composites including carbon fiber and fiberglass
Job Setup
Switching Blades
- Remove the table to expose the reservoir and the saw blade arbor
- Insert the two pins into the saw arbor and blade retaining nut normal to the surface of the arbor
- Using the leverage on the pins, loosen the blade retaining nut to free the blade
- Carefully remove the blade from its arbor and replace with the blade matching the material you intend to cut (blades should be inspected for ware and cracks, damaged blades should be disposed of in the broken glass box)
- Lightly LUBRICATE the threads on the end of the blade arbor with silicone grease to prevent thread galling. Silicone grease is on the bottom shelf of the chemical storage rack between the two fume hoods.
- Tighten the blade retaining nut HAND TIGHT (no need to go crazy on this)
- Check to make sure that the blade is submerged in the coolant by about 0.25 inches. The required coolant level will depend on the blade diameter.
- Replace the table
Blade Selection
- CBN Bond blades are used for cutting ferrous metals. Metal bond blades <1,000 RPM, Resin bond blades >1000 RPM
- Diamond Metal Bond blades: high concentration blades for general use at high or low speeds, low concentration blades for ceramics, Silicon, glass. Cut at low speed ,1,000 RPM
- Plated blades (diamonds nickel-plated to the rim) are good for cutting plastics, PCBs and composites. Cut at low or high speeds
