Haimer Repair & Vise Jaws Part 1

Doom, Haimer Repair & Vise Jaws Part 1

Things that happen when machining. Haimer 3D probe repair. Machining some softjaws.

My first week experience with the Haimer 3d Universal Probe did not go great. With in 30 minutes I had broken a tip. A few days later while running a part the probe fell from the BT40 ATC pot and damaged it. I contacted the manufacture and was advised repairs were not possible. No parts other than the probe tips are available.

At this point the expensive indicator was a door stop so I decided to disassemble it. I began assessing the damage, zeroing the indicator via 4 grub screws, and clean up of the rubber boot ring. I used my lathe to check out the probe position and accuracy. It now works just fine.

Fanuc Keysheet Replacement DIY HowTo

Fanuc Keysheet Replacement DIY HowTo

I have a Excel PMC 5V20 Vertical Machining Center with a Fanuc OM control. Keys below the CRT were busted and damaged. After purchasing a new keysheet, I verified fitment. The keysheets for the Fanuc are glued on and need to be removed and reapplied.

After cleaning the front of the Fanuc bezel, I replaced the keysheet and the control looks like brand new. In conclusion, I'm really happy with the results and the PCB board is again protected from coolant and other contaminates.

Home Shop Garage VMC Machining.

Home Shop Garage VMC Machining.

Home Shop Garage VMC is machining parts. I did some test cuts and rigid tapping in 6061. I purchased a used mill and moved it into my home shop. So far, the mill is in good condition and making tolerances on parts. It has taken some time to go from an older HAAS control to the Fanuc OM control.

First chips from the new mill and DNC controller testing.

First chips from the new mill and DNC controller testing.

First chips, file io with new controller and drip feed testing to the Fanuc OM.

Cutting the first chips on the CNC Mill. I used a Titan Ausys DNC to upload code to the Mill. Tested workflow getting programs on the mill directly. I also tested drip feeding programs to the Fanuc OM.

Toolchanger finally working again!

ATC Finally working again!

Late night of work but the toolchanger is now working. The issues was a simple one. The motor that drives the toolchanger was out of phase. It was in reverse rotation. I switched L1 and L2 connections. The toolchanger for the CNC Mill now works like it should.

ATC Troubleshooting on the Excel Mill / Fanuc OM

ATC Troubleshooting on the Excel Mill

Troubleshooting the automatic toolchanger on the cnc mill.

I put some G-Code on the machine with a Titan DNC. Noticed issues getting toolchanges to happen. I went over the Fanuc Ladder determine what was happening. Finally, I decided to start tearing into the ATC to debug. I also did some more cleaning and maintenance of the toolchanger. I removed guards and the main three phase drive motor.

First Power Up of the VMC mill in the shop

First Power Up of the VMC mill in the shop

First power up of the Excel VMC CNC into the shop. Testing of the American Rotary three phase AD-20 converter with the Mill.

After verifying the three phase connection voltages and placing the high leg on non-control leg inputs of the machine I powered the machine on without issues. I did initial leveling using the bed with the center bed screws loose. All the rigging preventing table and Z axis movement was removed. I used simple green cleaner for most of the machine. The automatic tool changer area I used purple power. A fresh load of coolant will do the rest of the cleaning for me.

I did have an issue after startup with a servo drive alarm. It ended up being a fiber optic connector on the Fanuc controls. After reconnecting, everything worked fine.

Moving the VMC into the Garage.

Moving the VMC into the Garage

Moving the Excel VMC CNC into the shop. I used 1" steel to roll the VMC into the location I wanted in the shop.

The CNC Mill was shipped on a hot shot trailer to a local yard. The yard used a large forklift to move the mill to a rollback wrecker that transported and slid the mill into the shop. I used a hydraulic mini cylinder to lift the machine and placed 1" steel rod underneath. I shifted the machine around with a long prybar. Both the rollback wrecker and Egyptian style of moving the CNC mill worked great. I was able to place the machine exactly where I wanted it in the shop.

Putting a VMC in a home garage is dream of many and I'm so glad to have a larger VMC back in the shop. There is a lot left to do to get this in operation. Things to consider are tooling, power, air, cleaning, coolant and a few other odds and ends.

This wasn't my first VMC and wasn't the first large piece of equipment I've installed in the shop. With that being said it wasn't much different than the first and I'd encourage anyone into a home machine shop to just plan careful and have a Plan B,C,D ready to go.

Machine moving into the home shop checklist...

1. Will it fit? (Making it thru the entry, ceiling height. etc)
2. How is it getting to the shop? (Rollback, Semi, Trailer)
3. How is it getting inside the shop? (roll on steel, machine movers, etc)
4. How am I powering it? (3 phase, 1 phase)
5. Do I have the proper tools to set the machine up? (Level, Air)
6. Do I have items to complete a test run of the machine? (Coolant, Tooling, etc)
