The Roller Hold-Down (RH-Series) of 3-Axis fixed bridge CNC routers maximizes speed and output when cutting large quantities of single sheets or stacked sheets, or when machining parts too small to be held by vacuum alone. The four rollers help to prevent accidental slippage of the top sheet of stacked material and provide the holding power for effective, accurate cutting of warped sheets to minimize waste and maximize yield. The regulated pressure of each roller prevents premature wear and “slamming” of the rollers. When cutting single sheets, or other materials such as plastics or aluminum, the rollers can be disengaged.
Integrate C.R. Onsrud’s automated material-handling systems that fit the flow of your production. With customized linear and cell-based solutions, you get as much or as little automation as you need, from simple loading/offloading with or without pre-labeling to fully automated material storage and retrieval systems with integrated routers and saws. See also Automation for more information.
By adding a second spindle, you can double your production by performing machining operations simultaneously on the same machine. For larger parts, park one spindle to have access to the entire table.

AUTOMATIC GREASE LUBRICATION
Automatically greases your tools, bearings, and ball screws at regular intervals.
Dust management systems connected to appropriate dust collection systems capture chips, dust, and other airborne particles that would otherwise be harmful to humans and the machining environment. We offer dust management systems that are geared toward the materials you’re machining and your production environment.
DUST HOOD
Targeted to the machining area, a dust hood suctions away dust and debris that can impact your health as well as the performance of your CNC machine.
Note: Due to the range of motion required for 5-axis machines, a machine enclosure is recommended over a dust hood.
DUST STANCHION KIT
Designed for low ceilings and shop floors with layout constraints, a dust collection stanchion kit transitions dust to your collector from either side of the machine.
OVERHEAD OFFLOAD DUST HOOD
Targeted to the machining area, a dust hood suctions away dust and debris that can impact your health as well as the performance of your CNC machine.
AIR KNIFE
Engineered especially for fine or coarse chips (e.g., hard composites, fiber cement, metal, etc.), programmable air knives clear harmful debris from your linear guides.
REAR ENCLOSURE
Partial standalone enclosures provide additional safety when the back of a machine is not against a wall.
MANUAL SLIDING DOORS
These doors are manually controlled by you for access to the machine’s enclosure. For safety purposes, the doors should be closed when the machine is in operation.
AUTOMATIC SLIDING DOORS
These doors are activated and controlled by PMC servo motors. For safety purposes, the machine is placed in a feed hold state if the doors are not properly closed.
ENCLOSURE DUST COLLECTION PORTS
Dust collection ports are integrated with your vacuum system to move dust and debris away from the work area.
LASER SAFETY SCANNER
The Onsrud Laser Safety Scanner sets an invisible barrier that triggers your machine’s E-Stop when crossed.
SENSING MATS
Sensing mats sense the pressure of an operator or object on them, alerting the machine to turn off.
Automated material-handling systems fit the flow of your production to make manufacturing processes more efficient and safe.
STATIC PRE-STAGE TABLE WITH OR WITHOUT PUSHER
Automatically reloads the scissor lift with another bunk of material prior to the first bunk running out. Since your material load is always stocked, you never have to synchronize your forklift timing or stop production.
SIDE LOADER
The side loader uses vacuum to lift material from the side of the CNC machining table enabling an operator to safely and automatically load heavy materials.
REAR LOADER
The rear loader uses vacuum to lift material from the back of the CNC machining table enabling an operator to safely and automatically load heavy materials.
PUSHER SWEEPER
The pusher automatically clears the machining area by moving parts to an offload table while the sweeper sucks up any additional dust and debris.
STATIC OUTFEED
A static outfeed table provides a work area for sorting and stacking parts without interrupting the machining operations.
CONVEYOR OUTFEED
Safely and automatically moves parts (e.g., heavy and bulky ones) down your machine’s production line for easy off-loading.
PRE-LABELING SYSTEM
Pre- or post-affix removable labels to parts for tracking, identification, or to provide descriptive details. (Most common for cabinets and sheet goods).
PART MARKING - INK
Applies marks (e.g., alpha-numeric), without contact, for part tracking. Marks can be permanent or removed based on how porous the material is.
PART MARKING - PAINT
Applies one or multiple colored paint for layout lines and shapes/symbols needed downstream (e.g., hot/cold water lines, nail locations, wiring, etc.) (Commonly used in the prefab home industry).
STANDALONE LABEL PRINTER
This auxiliary equipment can create and affix labels to parts for tracking and identifying parts for use in downstream operations or at the job site.
BARCODE SCANNER
Scan a barcode (machine-readable data) from a document and the machine automatically retrieves the specified program, tooling list, and set-up directions for that job.

Note: (Requires a 5-axis machine unless an aggregate is utilized)
These devices accurately locate your workpiece in orientation to the table and the tooling. To properly secure your workpieces, it is important to have the correct work-holding device for the material you are cutting. Proper work holding and material positioning ensure precise and efficient machining.
CUSTOM VACUUM ZONES
With custom vacuum zones, you tailor the size and location of vacuum areas for part-holding and can shut off sections of the table to concentrate vacuum to specific zones.
ONSRUD MATRIX GRID TABLE
The Onsrud grid table provides a grid pattern for multiple part-holding options, such as gasketing, vacuum pods, clamps, etc. and is compatible with most third-party products.
CUSTOM / MECHANICAL FIXTURING TABLE
Custom fixturing is adapted to hold irregularly shaped parts or panels that cannot be held by traditional methods.
T-SLOT
The channels of T-Slot tables are used for linear positioning of clamps and vices across the surface of the machine’s table.
ROLLER HOLD-DOWN
Roller hold-down uses rollers to apply pressure to the top of your material for additional hold and flattening of stacked, warped, or porous materials.
Note: This option is common for plywood processing, foam panel processing, and composite sheet processing.
REFERENCE (POP-UP) PINS
Reference pins are for quick, reliable, and repeatable placement of your workpieces on your CNC machine.
SURFACE PROBE
A surface probe or part finder helps your machine accurately identify the position of your material on your worktable.
PROBING
(RENISHAW PROBE)
A part-probing system adjusts the origin of your part prior to machining, performs in-process QC for tight tolerance applications, and performs post-machining QC to approve or reject a part before it is taken out of its work holding.
LASER PATTERN PROJECTION SYSTEM
Without touching the material, a Laser Pattern Projection Alignment System provides true to scale patterns of one or several aligned or nested objects, transferred from CAD software onto the CNC table.
Note: This option is common for high-mix shops and when using vacuum pods.
VISION RECOGNITION (FIDUCIAL)
A fiducial vision recognition system scans for reference points to identify a sheet’s position. The program and tool paths automatically adjust to the position.
Note: This option is common in the signmaking industry where sheets are otherwise difficult to align perfectly.
