Stop Setting It Up Twice.

Keyways shouldn’t be a production bottleneck.
But they still are.
Not because they’re complicated—
because the process around them is.
The Problem Isn’t the Feature. It’s the Workflow.
Need a keyway, slot, or internal feature?
Now you’re choosing between:
Broaching (if you even have the setup)
Wire EDM (slow + expensive)
Secondary ops on another machine
Sending parts out
So what happens?
You break the workflow:
Pull the part
Re-fixture it
Re-indicate it
Hope alignment holds
Now you’re stacking:
Time
Cost
Risk
All for a feature that should’ve been done in-cycle.
What Shops Actually Deal With
- “We’ll just broach it later.”
- “That has to go to EDM.”
- “We don’t have that capability in this machine.”
- “We lost position when we moved it.”
- And the hidden one:
- You just turned a one-op part into a multi-op problem.
duMONT CNC Slotting Brings the Operation In-Machine
The duMONT CNC Motorized Slotter converts rotary motion into a controlled vertical reciprocating stroke.
Meaning:
Your machine can now
slot, keyway, and shape internal features
without ever removing the part.
What That Actually Changes
Single-Setup Machining
No part transfer
No re-indicating
No alignment risk
You cut the feature exactly where it belongs.
CNC-Controlled Stroke
- Programmable positioning
- Controlled depth and feed
- Repeatable results
- No manual broaching variability.
Live Tool Compatibility
Runs on CNC lathes or mills with live tooling
Integrates directly into existing programs
No dedicated slotting machine required.
Flexible Tooling
- Keyways
- Internal splines
- Slots
- Form features
- If it can be cut with a reciprocating tool—it can be done in-cycle.
What That Means on the Floor
- No secondary operations
- No outsourcing
- No fixture changes
- No lost alignment
- You stop building workarounds…
- …and start finishing parts in one setup.
The Result
- Reduced cycle time (no additional setups)
- Improved positional accuracy
- Lower cost per part
- Faster turnaround
- Increased machine utilization
- And most importantly:
- You keep the entire process under your control.
Bottom Line
- If you’re moving parts to finish internal features…
- You don’t have a tooling problem.
- You have a workflow problem.
- The duMONT CNC Motorized Slotter fixes both.
