If you’re looking for a rotary indexing table, and you have specific application requirements, Weiss has just what you’re looking for. Their line-up of indexing tables includes fixed position, freely programmable, heavy duty, direct drive, as well as hybrid units.
With that in mind, here’s a brief synopsis of what each entail.
Fixed Station Indexers (TC and TR)
Fixed Station or Fixed Position indexers involve the use of a high-precision barrel cam with a dwell. With these units the movement pattern is determined by the cam track. They’re highly accurate and offer a smooth motion profile, offering zero backlash due to tensioned cam followers at the stop positions.
With fixed station indexers once the number of stops has been determined there is no going back. Unlike freely programmable indexers you cannot change the number of stops down the road.
Here are a few of the more salient features:
- 4-year mechanical warranty
- Never need to change the oil (low maintenance)
- No need for an overload clutch
- TC indexers offer 2 to 60 positions
- TR indexers (ring indexers with a large open centre) offer 4 to 36 positions
- With the Weiss line of TR ring indexers, the cam followers run along the entire outside perimeter of the track offering greater accuracy
- Lots of stock at the Weiss location in Willoughby, Ohio
- Triple bearing of rotary plates (helps with high loads)
- Mechanics are stronger than the motor: cannot break the cam followers. With other manufacturers you need to invest in an overload clutch. With Weiss you cannot exceed the permitted inertia. Their weak link is the motor coupler, with is inexpensive to replace.
- Multiple drive positions, multiple mounting positions, stationary centre with a through hole, side window for cabling
- All surfaces from the casting to the rotating dial plate to the stationary plate have accurate mounting holes. All you need to do is transfer our bolt hole and dowel hole pattern to your mounting plate.
- Very low profile – the motor and belt pulley housing always has a smaller profile than the casting itself, so you don’t have any costly cut-outs in your machined top plate
Weiss Freely Programmable Indexers (NC, NR, CR)
For the Weiss line of freely programmable rotary indexing tables, you have the option of choosing a NC, NR, or CR.
The NC rotary indexing table offers the robustness and reliability of the TC series indexers, with the added advantages of a freely programmable rotary indexing system.
NR – this is like the TR indexer with the large center hole, with the added advantage of utilizing a freely programmable system.
CR – this is the Heavy-Duty version of the Weiss line of freely programmable rotary indexing tables.
Here are some of the more salient features:
- Constant lead cams
- No “in-station” prox switch
- Optional secondary encoder for the NC version of freely programmable indexers. We can supply the encoder or prep the unit to mount a customer supplied encoder. When the customer supplies the encoder, we simply provide a plate to cover up the spot, which the customer then removes when it is time to install their encoder.
CR Heavy Duty Indexers
- The CR heavy duty rotary indexing rings provides a lot of power and precision in an extremely small size
- Great for applications calling for high loads & forces
- Often used in body shop applications for automotive welding
- More cam followers engaged, which increases the amount of inertia the units can carry, and provides for better a stop time for light curtain applications
- Always has 5 cam followers engaged
- Quick index times
- Quick e-stop times
- Low profile
Weiss Direct & Hybrid Drive Indexers
ST – Torque Rotary Table
- Small & compact. About the size of a beer can
- Commonly put on the end of a tool
- Very lightweight
- Think of this indexer when you need fast, precise, highly dynamic rotation, or tilting, and when gripping motions are required
- Great for feeding or orienting parts, or as a swivel module for grippers
- No oil, no gears
- High power density
- Any installation orientation is possible
- Absolute encoder
- Long service life
- Optional holding brakes are available
TO – Torque Rotary Table
- User programmable direction of rotation
- Direct, rigid connection of the load to the drive
- High speeds
- Highly accurate and repeatable
- All motors are equipped with over-temperature protection
- Long service life (low maintenance)
- Lubricated for life
Weiss TW Hybrid Drive Rotary Tables
- Designed to greatly outperform pneumatic indexing solutions
- Much faster than pneumatic solutions; more precise; very little dwell time
- Higher power density than pneumatic solutions
- Precise teaching of each position
- Electronic overload protection
- Integrated holding break
- Hybrid drive includes gear reduction
- Servo and gear are built inside the unit
- Permits any installation orientation
