| Vo-Tech has served the power generation industry for the past 15 years. In fact, the company’s owner has been involved for many more years and that is primarily how we got our start as a machining and service company (See “History” for more info).
Vo-Tech offers and has provided the following services to the power generation industry >> |

Please also see the “Custom Tooling” and “Machines Designed & Built” sections for more tools and equipment, not mentioned here, and more pictures of each of these items listed below.
Below is a brief list of the machinery and equipment we have designed and supplied specifically to and for the Power Generation Industry:
Note: These items have many applications adaptable to other industries than just the power generation industry. If you have a specific need/requirement or don’t see what you need here……..…….call us with the challenge to design something for you.
MSIV Machine System
The industry’s first ever remotely operated automatic CNC/Servo controlled complete system
- One time setup to complete all needed repairs
- Laser accurate measurement head - documents dimensional data acquisition
- Dual boring bar attachments for line boring, flange and seat machining
- Milling head attachment for spot machining/repairs
- Automatic welding head attachment
- Lapping head attachment for seat finishing
- Reduces exposure and repair time
- Fully remote operation up to 50’ away
Portable Milling Machine
(Compact Design Horizontal Boring Mill)
- Design custom scalable to virtually any size requirement
- Precision ground lead screw with zero backlash
- Precision Linear Guides and Roller Bearings (heavy duty)
- Existing design very rigid that can easily handle 2,000 lbs. table load
- Travel capability: 28” in X axis, 32” in Y axis, 12” in Z axis (on 36” X 36” table)
- User friendly Windows based Mach Motion CNC Controls with built in CAM feature & optional 4th axis capable
- Touch Screen Monitor with custom views and tool path features
- Jog handle control with track ball and keyboard inputs
- 6.6 HP Spindle with speeds up to 3,000/1,500 RPM’s with torque at 111/222 inch lbs. (depending on desired configuration)
- Common CAT 40 tool holder (unique for a horizontal mill)
- Small footprint of only 85” in length (Z) X 79” long (X)(L shaped design) and only 73” tall overall
- 4,500 lb. machine that is easily disassembled and transportable
Flange Machine
- Hydraulically operated
- Internal or Externally mount capable
- OD & ID machining capable up to 36“ diameter
Engine Bearing Gauge Tool 
Designed to fit into the cavity of an assembled engine replacing the bearing halves and measuring ID & OD surfaces of crankshaft and bearing housing to measure and spec. a replacement eliminating the need of entire disassembly
- Scalable to measure shafts 12” to over 30” in diameter
- Measurement accuracy to within +/-.0005 to 1 degree increments across 5” in width (also scalable to wider dimensions)
- Working 14” model has 8 ID and 8 OD probes
- Collected data downloadable to PC w/proprietary software
Stud Cleaning Machine
(for studs from Vessel Reactor Domes)
- Designed to automatically clean studs of corrosion and contaminants
- Helps reduce likelihood of cross threading and/or lockup increasing down time
- Reduces thread wear prolonging life of studs
- Speeds up assembly of Dome saving time on exposure improving safety
RVDS Pneumatic Nut Runner
- Assists in the removal of the studs for reactor domes by capturing the lower nut and washer preventing loss or expensive recovery while reducing employee exposure
- Also holds nut and washer during assembly minimizing employee fatigue
RVHS Nut Runner (electric)
- Assists in speeding removal or assembly of top nut readying for torque - saves time and reduces employee exposure
Stud Lifting Wrench
- This custom wrench was developed to expedite the process of disassembly and assembly of the reactor vessel drywell dome. After dome studs are de-tensioned and bottom nuts removed, this wrench is used to lift the studs to set in position before removing the dome.
- Pneumatically operated tool to raise or lower assembled studs on reactor dome – saves time & reduces exposure
Probe Exchange Device
- Adaptable and scalable to many different sizes/pressures depending on need
- Allows for the exchange of probes without compromising system pressure
- Prevents system(s) having to be shut down to change out probes (moisture, temperature or any other critical sensor needed replacement)
- Permanent solution quick disconnect design saves time and allows for replacement should failure occur – especially during a non-outage cycle
Seal Testing Machine
- Designed to perform testing on mechanical seals with upwards of 1,000 PSI before installation
- Pre-testing saves cost of labor to install and remove should seal failure occur
- Saves on downtime and improves employee safety
Accumulator Cart
- Designed to install, remove and transport accumulators in space restricted areas
- Assists with labor when normal rigging equipment space limited
Stud Tensioning Wrench
- Clutch actuated wrench that eliminates physical need to loosen/tighten fasteners operated manually or automatically
- Eliminates worker fatigue for otherwise difficult removal in a contaminated environment improving safety
- Upgrade to existing pressure vessel stud tensioning wrench
Tilt Camera Module
- Developed to remotely operate a crawler for visual inspection of vessels and pipes
Sealed Cable Adapter
- Adaptable and scalable concept for multiple size ranges/capacity’s if needed
- Universal design both pivots and rotates where this is a requirement
- Developed with sealed components to function in corrosive/harsh environments
- Very strong. Current design is load rated at 1,000 lbs.
MSIV LRT Plug
- Designed to isolate MSIV loop during Leak Rate Testing
- Saves considerable time as compared to having to assemble entire valve to achieve same test
- Reduces labor and improves employee safety
