Stop stacking 1-2-3 and 2-4-6 blocks just to get the work high enough.
The Rogue Machine 10" 5 Axis Riser Block gives you a reusable way to raise a fixture or workpiece when you need more clearance around the setup. Articulating-head 5-axis work is a primary use case, but the same elevation problem can show up on horizontal machining centers, boring mills, high-column machines, large VMCs, CNC routers, and unconventional one-off fixtures.
The riser is built from 6061 aluminum, welded first, then machined. The machine-table seating surface and upper workholding surface are machined after fabrication, and every finished riser is 100% inspected before shipment.

Where a Tall CNC Riser Can Help
Sometimes the machine has plenty of travel, but the setup is simply too low for the spindle, head, toolholder, or cutter to reach the feature the way you want. Raising the workholding plane can open up additional access around the part.
- Head-head 5-axis and articulating B/C-axis machines
- Horizontal machining centers and horizontal boring mills
- High-column and specialty CNC machines
- Large vertical machining centers with unusual fixture setups
- Large-format CNC routers
- One-off jobs that would otherwise require stacks of setup blocks or a custom pedestal
5-Axis and Articulating-Head Clearance
On head-head 5-axis, gimbal-head, and other articulating-head CNC equipment, the physical size and motion of the B/C-axis head, spindle, and toolholder can limit access when the workpiece sits close to the machine table. Additional fixture elevation can provide more room to approach side features or angled geometry.
Mounting and Application
The riser can be toe-clamped to an appropriate machine table. Mounting hardware is not included. Because every machine and setup is different, the buyer should verify the machine envelope, table interface, clamping arrangement, fixture/workpiece geometry, available travel, and planned application.

Frequently Asked Questions
Is this only for 5-axis machines?
No. 5-axis and articulating-head machines are an important application, but the same need for fixture elevation can occur on horizontals, boring mills, high-column machines, VMCs, routers, and unusual workholding setups.
How tall is the riser?
10 inches. Rogue Machine currently offers this product only in the 10-inch configuration.
What is the workholding pattern?
The top uses 1/2-13 form-tapped holes on 1.25-inch centers for flexible fixture and workholding placement.
How accurate is the riser?
Overall height is held to ±0.001 inch, with parallelism of less than 0.001 inch.
How much does it weigh?
Approximately 37 lb finished. Packaged / shipping weight is approximately 42 lb.
How does it mount?
It can be toe-clamped to an appropriate machine table. Mounting hardware is not included.
Does Rogue publish machine-specific fitment?
No. Buyers should verify their own table interface, machine envelope, clamping arrangement, fixture/workpiece geometry, and planned application.
What is the maximum load?
Rogue Machine does not currently publish a calculated or tested load-capacity or overturning-moment rating.
Is it machined after welding?
Yes. The aluminum structure is welded first and then machined. The table-seating and upper workholding surfaces are machined after fabrication.
Is every riser inspected?
Yes. Every finished riser is 100% inspected before shipment.
