CNC technology allows us to harness MagnaCut Steel’s properties, from its high hardness to its corrosion resistance, to create knives that perform as well as they look. This section covers the processes, tools, and tips for machining MagnaCut Steel, along with real-world insights to help you succeed.
CNC Machining Processes for MagnaCut Steel
CNC machining MagnaCut Steel involves several key processes: milling, grinding, and polishing. Each step requires careful consideration to maximize the steel’s potential while minimizing tool wear.
Milling MagnaCut Steel
Milling is often the first step in shaping MagnaCut Steel blanks. The steel’s high hardness (up to 64 HRC after heat treatment) demands specific settings to avoid overheating or tool damage. I’ve found that low cutting speeds (50-80 m/min) and high feed rates (0.05-0.1 mm/tooth) work best. These settings reduce heat buildup, which can affect MagnaCut Steel’s properties. Using shallow depths of cut—typically 0.5-1 mm per pass—helps maintain tool life and prevents surface defects like scratches.
In my experience, milling MagnaCut Steel in its annealed state (before heat treatment) is easier for roughing out shapes. I once milled a batch of MagnaCut Steel knife blanks on a 3-axis CNC machine, and the process was smooth as long as I kept the coolant flowing. Coolant is critical—it prevents thermal stress and keeps the workpiece surface clean.
Grinding for Precision
Grinding is where MagnaCut Steel shines in CNC machining. Its uniform microstructure makes it less abrasive than other high-alloy steels, reducing wear on grinding wheels. I recommend using cubic boron nitride (CBN) wheels for the best surface finish. In my workshop, I’ve used CBN wheels to grind MagnaCut Steel blades to a near-mirror finish, achieving tolerances as tight as ±0.01 mm.
Grinding parameters depend on the desired outcome. For rough grinding, I use a wheel speed of 20-30 m/s and a feed rate of 0.02-0.05 mm/pass. For finish grinding, slower speeds and lighter passes (0.01 mm) produce a smoother surface. I learned the hard way that rushing the grinding process can lead to burn marks on MagnaCut Steel, so patience is key.
Polishing for a Flawless Finish
Polishing MagnaCut Steel with CNC equipment is a joy. The steel’s fine grain structure allows it to take a mirror-like finish with minimal effort. I’ve used CNC-controlled polishing heads with diamond paste to achieve a reflective surface on MagnaCut Steel blades. The process typically involves multiple stages, starting with coarse abrasives (400 grit) and progressing to ultra-fine compounds (2000 grit or higher).
In one project, I polished a MagnaCut Steel knife blade to a mirror finish using a CNC grinder. The result was a blade that not only looked stunning but also performed exceptionally, with a smooth edge that sliced effortlessly. For CNC polishing, maintain low pressure and consistent speeds to avoid overheating, which can compromise MagnaCut Steel’s hardness.
Tool Selection and Parameter Optimization
Choosing the right tools is critical when machining MagnaCut Steel. Its high hardness can wear out standard tools quickly, so I stick to carbide or ceramic-coated end mills and inserts. In my workshop, I’ve used carbide bull-nose end mills for milling MagnaCut Steel, as their rounded edges reduce chipping compared to square-end mills.
Here’s a table summarizing recommended tools and parameters for CNC machining MagnaCut Steel:
| Process | Tool Type | Cutting Speed (m/min) | Feed Rate (mm/tooth) | Depth of Cut (mm) | Coolant |
| Rough Milling | Carbide Bull-Nose End Mill | 50-60 | 0.07-0.1 | 0.5-1.0 | Flood Coolant |
| Finish Milling | Carbide End Mill (Coated) | 60-80 | 0.05-0.07 | 0.2-0.5 | Flood Coolant |
| Rough Grinding | CBN Wheel (120 Grit) | 20-25 | 0.02-0.05 | 0.05-0.1 | Mist Coolant |
| Finish Grinding | CBN Wheel (400 Grit) | 25-30 | 0.01-0.02 | 0.01-0.03 | Mist Coolant |
| Polishing | Diamond Paste (400-2000 Grit) | 10-15 | 0.005-0.01 | 0.005-0.01 | Dry or Light Mist |
| Drilling | Carbide Drill (TiAlN Coated) | 40-50 | 0.03-0.05 | 0.5-1.0 | Flood Coolant |
| Tapping | Carbide Tap (Coated) | 10-15 | 0.02-0.03 | N/A | Flood Coolant |
These parameters have worked well in my experience, balancing efficiency with tool longevity. Coolant is non-negotiable—without it, you risk burning the MagnaCut Steel or damaging your tools. I once skipped coolant during a test run and ended up with a discolored blade surface, which was a costly lesson.
Recommended CNC Equipment for MagnaCut Steel
Choosing the right CNC equipment is essential for machining MagnaCut Steel effectively. In my workshop, I’ve experimented with both industrial and desktop CNC machines, and I’ve learned that the right setup can make or break your project. For professional knife makers, a 5-axis CNC machine is ideal for MagnaCut Steel. These machines offer the flexibility to create complex blade geometries, such as compound bevels or contoured handles, with precision. Brands like Haas and DMG MORI produce 5-axis machines that handle MagnaCut Steel’s hardness without flinching. I visited a local machine shop last year where they used a Haas VF-2 to mill MagnaCut Steel blanks, and the results were flawless—clean edges and tight tolerances.
For small workshops or hobbyists, desktop CNC machines are a great option for MagnaCut Steel.

Desktop CNCs are also budget-friendly, making MagnaCut Steel accessible to enthusiasts who want to craft high-quality knives without breaking the bank.
When selecting a CNC machine for MagnaCut Steel, prioritize rigidity and spindle power. MagnaCut Steel’s high hardness can stress low-end machines, leading to vibration or poor surface finishes. I learned this the hard way when I tried milling MagnaCut Steel on an underpowered hobbyist CNC— the chatter marks on the blade were a nightmare to remove. A machine with at least 5,000 RPM and a robust frame is a safe bet for MagnaCut Steel projects.
Case Study: MagnaCut Steel in Action
To illustrate how MagnaCut Steel performs in CNC machining, let’s look at a real-world example. Spyderco, a leading knife brand, has embraced MagnaCut Steel for its Salt series, designed for marine environments. I had the chance to tour a knife manufacturing facility where Spyderco’s CNC processes were in action. They used a 5-axis DMG MORI machine to mill MagnaCut Steel blanks into precise blade shapes, followed by CNC grinding to create razor-sharp edges. The facility’s engineer shared that MagnaCut Steel reduced their tool wear by about 15% compared to M390, saving time and costs.
Here’s a breakdown of Spyderco’s CNC process for MagnaCut Steel, based on my observations and industry insights:
| Process Stage | Equipment | Time per Blade (min) | Cost per Blade (USD) | Key Advantage |
| Rough Milling | DMG MORI 5-Axis CNC | 10-12 | 2.50 | Precise blank shaping |
| Finish Milling | Haas VF-3 | 8-10 | 1.80 | Smooth surface preparation |
| Rough Grinding | CNC Surface Grinder (CBN Wheel) | 6-8 | 1.20 | Reduced wheel wear with MagnaCut Steel |
| Finish Grinding | CNC Grinder (CBN Wheel) | 5-7 | 1.00 | High edge precision |

Tips for Optimizing CNC Machining of MagnaCut Steel
Machining MagnaCut Steel isn’t without challenges, but a few tricks can make the process smoother. First, always machine MagnaCut Steel in its annealed state for roughing operations. I made the mistake of milling a hardened MagnaCut Steel blank once, and my carbide tools wore out twice as fast. Roughing in the annealed state saves tools and time, leaving final grinding for after heat treatment.
Second, monitor coolant closely. MagnaCut Steel is sensitive to thermal stress, and insufficient coolant can cause micro-cracks or discoloration. I use a high-pressure flood coolant system in my workshop, which keeps the workpiece cool and flushes away chips. Third, invest in quality fixturing. MagnaCut Steel’s hardness can cause slipping in low-quality vises, leading to inaccurate cuts. A precision vise or custom jig ensures stability during CNC operations.
Finally, don’t skimp on tool maintenance. I check my carbide end mills after every few passes when machining MagnaCut Steel, as even minor wear can affect surface quality. Regular tool inspection and timely replacement keep your CNC process efficient and your MagnaCut Steel blades pristine.
