| − | =====Work Holding=====
| |
| − | {{Note|type=warning|text=Treat the fixture plate as a precision instrument. It is precision ground out of 6061 Aluminum, and won't function correctly for long term use if it excessively nicked or scratched.}}
| |
| − | *[https://saundersmachineworks.com/products/tormach_1100_aluminum_fixture_plate Saunders Machine Works fixture plate]
| |
| − | **The fixture plate allows for precision, repeatable placement of vises and fixtures, greatly improving the speed of making multiple parts.
| |
| − | **'''The fixture plate is 34" x 12". The Tormach travel is only 18" x 9.5". This means that much of the fixture plate can't be reached by the spindle, so before fixturing a part to the table, make sure it will be accessible.'''
| |
| − | **The fixture plate is trammed to the mill table movement. Do not loosen or remove the low-profile screws in the fixture plate that secure it to the mill table, it is quite difficult to re-tram and in almost all cases, unnecessary to remove.
| |
| − | **The holes are spaced 1.25" on-center
| |
| − | **Each hole in the fixture plate will accept a 1/2" dowel pin for alignment or work stop use, and is also threaded for standard 1/2-13 bolts.
| |
| − | **To preserve the integrity of the threads in all of these holes, each hole is plugged with a black rubber plug when not in use. You should not operate the mill with any exposed holes, they should always have either a plug, a dowel, or a bolt in them. This keeps chips and coolant out and makes cleanup much simpler.
| |
| − | **To remove and replace the plugs, there is hook / pick tool in the tool chest. Pierce the center dot on the plugs with the pick, twist, and pull up. This motion will eventually deteriorate the plugs. If they appear to be in need of replacement, more are available in the tool chest, but simply piercing the center dot doesn't render them inoperable.
| |
| − | **The fixture plate works best with fixtures or mod vises. If you want to use a standard machine vise, it will bolt to the fixture plate using 1/2-13 bolts. The machine vise will need to be trammed with a dial indicator if you install it.
| |
| − | **Because the fixture plate is uncoated aluminum, it is subject to galvanic corrosion if steel or cast iron is left attached to it long term. There are small tubes of dielectric grease available in the tool chest. Ideally a thin coat should be maintained on the vises if they are being left on the plate for an extended period of time. The bottom of the plate has also been coated to prevent corrosion between the plate and the table. One tube of grease is enough to coat the entire surface area of the fixture plate, so use it sparingly.

| |
| − | **These are also precision ground instruments. Every surface is machined and the fixed-side jaw can be used as a reliable work coordinate system origin.

| |
| − | | |
| − | *The probe is in a labeled hard case in the tool chest. The case contains the probe, cable, and a very easy to miss hex wrench that is used for adjusting concentricity.
| |
| − | *The probe has already been indicated and measured in PathPilot, and should be ready to use.
| |
| − | *The probe's cable has been hot glued to the probe itself. If the cable is not connected to the probe for any reason, please red tag the machine so we can address that issue to prevent crashing and ruining the probe. To start, ALWAYS plug the into the DIN5 cable into the accessory port on the machine electronics cabinet FIRST. The probe will light up green when the connection is good. DO NOT proceed if the light is not on. The machine will happily crash and ruin the probe if you run a probing routine without power to the probe.
| |
| − | *Next, put the probe in the collet and tighten the collet. Light / hand-tight is sufficient. It's a good practice to leave the spindle cover door open while the probe is in the collet, this guarantees you'll never spin up the machine with the probe in the collet.
| |
| − | *Once the cable is connected and the probe is installed, select tool 99 in the tool DRO. The probe is hard coded in PathPilot to be tool 99.
| |

Safety
Universal Safety
- Be aware of your surroundings, especially when handling large materials.
- Do not approach anyone operating equipment. Stand patiently in their field of view.
- Use PPE, including filtration and eye protection, when handling dust or emptying dust/shaving containers.
Equipment-Specific Safety
Safety glasses must be worn when working with the soldering station, as solder can "spit." Never touch the tip of the soldering iron to avoid burns, and always work with the soldering iron above the workbench. When not in use, the soldering iron must be returned to its stand and never laid on its side. The fume extractor should be powered on while soldering to mitigate health risks from inhaling fumes, and skin contact with melted solder should be avoided.
The soldering iron should only be used for fusing solder, not for other purposes such as burning through materials. Avoid using the soldering iron on the plastic insulation of wires; instead, use a wire stripper to remove the insulation. Additionally, avoid prolonged contact between the soldering iron and PCB boards, as the iron should primarily make contact with the solder.
Prongs or tweezers are recommended for holding wires while soldering, minimizing the risk of accidental contact with the soldering iron and reducing the chance of burns from conductive heat in the wire. Finally, when finished using the soldering iron, always clean the tip before returning it to its station.
Use Case
Soldering uses a fusible metal alloy (solder) to join two metal surfaces by heating them and applying melted solder. It creates electrical connections on PCBs, allowing current to flow between the soldered components.
Materials
The soldering station can accommodate two common types of solder wire.
Tin-Lead Rosin Core Solder Wire
Typically has a low melting point, with excellent flow, wetting, and electrical conductivity. Contains lead, which poses health risks through the release of toxic fumes.
Lead-Free Rosin Core Solder Wire
Typically has a higher melting point, with good flow, wetting, and electrical conductivity. Produces less harmful fumes, making it safer to work with.
Setup
Preparing the Soldering Iron
- Turn the the power supply unit for the soldering iron.
- Adjust the temperature of the soldering iron as needed. 400°C typically works for most applications.
- Wait for about 2 minutes for the soldering iron to heat up.
- Pick up the soldering iron, burn some solder on the tip of the iron, and clean the tip with copper wool.
- Doing this before soldering helps improve heat transfer, prevent oxidation, and enhance soldering quality.
Soldering
- Use clamps to hold your board in place.
- Place the solder wire on the surface you wish to fuse with your wire, then position the soldering iron on top of the solder wire without letting the iron touching the surface. Hold it in place until the solder melts.
- A good solder joint should have a smooth, shiny appearance, indicating proper melting and wetting of the solder. It should also be evenly distributed around the connection and have no cracks or excessive lumps.
- Move the solder wire away, and hold your conductive wire on the melted solder.
- If the wire is insulated, use wire strippers to remove the insulation.
- Move the soldering iron away from the solder, allowing it to harden so that the wire remains adhered to the surface.
- Use the copper wool to clean the soldering iron after every solder.
Cleaning Up Solder
To clean up solder on a wire or surface, heat the solder with the soldering iron, then place a solder wick near the iron and solder to absorb the solder. You can also use a solder sucker to vacuum the melted solder.
Turning Off the Soldering Iron
When finished using the soldering iron, always ensure to clean the iron tip before storing it back to its holder. Turn off the heat when it is not used.
Cleanup
Universal Cleaning Guide
- Return the equipment to neutral.
- Sweep up any dust and debris around the tool, your table top, and the floor - both in the equipment area and your work area.
- Clear the floor of any tripping hazards, like power cords.
- Empty trash cans and dust collectors that are halfway full or more into the Asmbly dumpster behind the workshop.
- Leave the shop 110% better than you found it.
Tool Specific Cleaning Guide
- Hit the E-stop button on the outside of the enclosure
- Clean the whole interior of the enclosure
- Use the appropriate shopvac for the material you machined
- There is a squeegee on the left side of the machine. Use it to remove coolant and chips from the walls of the enclosure. Squeegee the table/fixture plate as well
- Don't forget to move the table of the machine to clean the accordion ways covers on both sides.
- Turn the rotary power switch off
- Return the console to beside the enclosure, out of the aisle
- Make sure the floor in front of the machine is clean and dry
- Return all tools to their proper places
- Return all tool holders to the drawer
Resources
Tooling
- Asmbly has a Tormach SuperFly cutter with inserts for aluminum. These inserts should not be used to cut steel
- There may be a limited selection of end mills and chamfering tools in the drawer with the tool holders
- Tooling used with the manual mills (in the cabinet across from the Rong Fu RF-45 Mill) can be used with the Tormach, but is not high quality and is considered a consumable (will not be replaced if worn or broken)
- It is recommended that you bring in the tooling that you need for your own jobs
