The LR-Series 5-Axis machine is a highly customizable machine. If you don’t find the accessories you need, please contact us to discuss your machining requirements and business goals.
C-AXIS
With a C-Axis (aka 4th axis), you can machine at an angle, including on the sides of your material, to create complex contours (such as helixes), otherwise not possible with a 3-axis machine. This comes standard on a 5-axis machine.
CONTINUOUS C-AXIS
With continuous C-Axis, a 5-axis machine gets unrestricted rotational movement of the C-axis. Without this option, a traditional 5-axis spindle has to unwind itself after a set amount of rotation.
AIR BLAST
Bursts of air keep tools cool and remove debris and chips from the cut without the need for coolant.
FLOOD COOLANT
Flood coolant absorbs the heat from high-intensity milling and removes the debris from your workpiece.
THROUGH-SPINDLE COOLANT
Through-spindle coolant prevents tools from softening from the excessive heat generally caused by deep drilling or heavy cutting operations in nonferrous metals.
ATLM SYSTEM (METROL)
Precisely measures the length of your tool and automatically feeds that value into your CNC machine controls.
ATLM SYSTEM: TS27R (RENISHAW)
Precisely measures the length and diameter of your tool and automatically feeds that value into your CNC machine controls. It also detects if a tool is broken.
ATLM: NC4 (RENISHAW)
Precisely measures the length and diameter of your tool, without contact, and automatically feeds that value into your CNC machine controls. It also detects if a tool is broken. NC4 is application dependent; table constraints may apply.
AUTOMATIC GREASE LUBRICATION
Automatically greases your tools, bearings, and ball screws at regular intervals.
GREASE DRIP PANS
Drip pans (a.k.a. trays) catch excess lubrication that might otherwise cause contamination or other hazards.
LINEAR ENCODER (SCALES)
With noncontact sensing, linear encoders (scales) measure and monitor linear movement, position, and speed and provide that feedback to your CNC machine.
VOLUMETRIC LASER COMPENSATION
With volumetric laser compensation, machining tools are automatically calibrated and the machine makes any necessary adjustments.
Note: Depending on your machine, C.R. Onsrud sends out a third-party A2LA-accredited company to your facility to perform volumetric compensation.
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. The LR-Series can be customized with dust and chip management systems you need, contact us.
BELLOWS ON X, Y, Z
Bellows (covers) keep abrasive materials out of your motion-controlled components.
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.
FULL ENCLOSURE WITH OR WITHOUT A ROOF
A fully enclosed machine contains debris, reduces noise levels, protects your electronics and mechanical drives from both wet and dry machining, and safely isolates the operator from the machining zone and airborne particles.
RETRACTABLE BELLOWS ROOFING SYSTEM
A bellow roof covers the top section of your machining mill to completely enclose it and contain debris. It can retract to give unobstructed access to a forklift or overhead crane and it can adjust with the movement of your spindle or gantry.
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.
CHIP PANS
Located beneath the machine’s vacuum table, chip pans collect dust and debris from the work environment. These can be manually cleaned or integrated with a dust collection system.

CHIP AUGERS
Used for materials that require flood coolants, chip augers funnel chips to the conveyor where they are removed from the machine’s enclosure and into a chip bin.
CHIP CONVEYORS
The chip conveyor carries away end cuts and other debris from your workspace.
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.
Automation systems are typically not integrated with the LR-Series except as listed below. If you are looking for material-handling, infeed and outfeed systems for panel processing applications, we recommend the T-Series, M-Series, or G-Series. See Automation for more information or contact us. We are happy to discuss options with you.
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.
ROBOTICS INTEGRATION
Devices are strategically incorporated into your production to automatically perform repetitive tasks, so you and your team can focus on projects that grow your business.
Onsrud Tooling is a direct and easy way to buy high-quality cutting tools at great prices for your Onsrud machine.
Drill Blocks support the simultaneous machining of a set number of holes, evenly spaced with the same or varying diameters. These are not available on a 5-axis machine, but if you’re interested in this capability, see our 3-Axis machines.
Depending on your specific application, the LR-Series 5-axis supports 1000’s of specialty tools to perform specialized functions for unique projects. Not all aggregates work with every machine configuration. We recommend discussing your specific application requirements with our team.
Saw Blades attach to a CNC machine to create intricate notches, miter cuts, and straight cuts on up to 5 sides of your material on a 5-axis machine. The saw can also be used as a cutoff tool.
Not sure what you need? We’ve got you covered, our knowledgeable staff is on hand to help with your tooling needs.
AGGREGATE RING
The Aggregate Anti-Rotational Retention Ring mounts to the underside of the spindle, giving it the capability to pick up specialized tooling from the Automatic Tool Changer and preventing the aggregate head from rotating during machining.
90° HEAD
A 90° head gives you the capability to perform lateral machining operations on a 3-axis machine.
DUO 90° HEAD
A Duo 90° head gives you the capability to perform lateral machining operations using different tools in opposite directions on a 3-axis machine.
QUAD 90° HEAD
With a Quad 90° head, you’ll easily add lateral machining operations to your 3-axis machine using four tools in each direction.
ADJUSTABLE ANGLE
An adjustable angle head allows you to set the angle at which you want to cut, for up to 5-sided machining on a 3-axis machine.
FLEX ANGLE
With a flex angle head, you can perform horizontal and angular machining operations on a 3-axis machine without having to reposition your workpiece.
MOULDER HEAD
Mill, plane, carve, and bevel, symmetrical and asymmetrical shapes on a 3-axis machine, with the addition of a moulder head aggregate.
OSCILLATING KNIFE
Cut out sharp corners and radii from flexible materials, such as packaging foam, tool foam, plastic, or cardboard with an oscillating knife aggregate.
SMALL DIAMETER SAW BLADE
(up to 6″)
The spindle automatically picks up and returns small diameter saw blades (up to 6″) from the station that is mounted on the machine’s bridge or column.
Note: (Requires a 5-axis machine unless an aggregate is utilized)
DEDICATED AGGREGATE STATION
With a dedicated aggregate station, you can automatically store and retrieve specialty tools (such as saw blades) that are too large or heavy to fit in a standard automatic tool changer.
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. The floor inside the LR-Series supports any type of fixturing.
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.
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.
