When a leading North American manufacturer serving the aerospace and defense industry began automating more of their CNC operations, one thing kept getting in the way: their workholding. 

Despite running a high-end UMC-1250 with a pallet pool, the shop was struggling with OEM-compatible base plates that simply couldn’t deliver the reliability or precision they needed. Misalignments, worn interfaces, and inconsistent pallet locking were creating delays, rework, and downtime—costing them both time and trust. 

Their team needed more than just compatible tooling. They needed a solution that would remove friction from their workflow—and a partner who understood what was at stake. 

The Breaking Point: A System That Couldn’t Keep Up 

Their EROWA MTS-compatible plates were supposed to streamline operations. Instead, they became the bottleneck. Each mismatch or mechanical issue triggered hours of manual corrections, interrupting the precision flow their industry demands. Even worse, long OEM lead times made it impossible to respond quickly when a replacement was needed. 

When the situation finally became unsustainable, they turned to Rapid Holding Systems. 

Listening First. Then Solving. 

We approached the challenge by doing what we do best: listening. The shop’s goal wasn’t just better tooling—it was to regain control. To achieve smoother automation, consistent results, and setup reliability they could trust. 

That’s where our MTS-Compatible Base Plate came in. 

Our recommendation: the RHS MTS Base Plate – EROWA ER-041600 Compatible, custom-built to their 180 x 360 mm configuration. With a 200 mm center distance between locators and lateral air-control access, it integrates effortlessly into robotic workflows and supports repeatable, high-precision setups. 

We also included optional boreholes for custom machine table configurations. 

From Test to Transformation 

After installing the first RHS base plate, the difference was immediate. 

Setup became faster. Precision improved. Downtime dropped. And their team could finally rely on the system to do its job—without micromanagement or backup plans. 

The real proof? They ordered two more systems, back-to-back. 

RHS had not only solved the problem—they had exceeded expectations. 

Cost Savings and Confidence 

Beyond performance, the switch to RHS brought another major advantage: cost savings. 

By choosing our MTS-compatible base plates, the manufacturer cut their palletization tooling costs by nearly 50%, while gaining better service and technical support. 

Our team worked closely with their engineers to make sure every detail aligned with their goals—not just in theory, but in daily production. 

A Better Way Forward 

This story is not just about a better tool. It’s about building a better process. 

With Rapid Holding Systems as a guide, the manufacturer turned a chaotic, unreliable setup into a streamlined, confident workflow. 

Now, they’re not chasing compatibility—they’re leading with it.

Let’s talk. 

Explore EROWA-Compatible Base Plates 

When it comes to aluminum diecast mold making, most shops know it’s no walk in the park. Unlike plastic injection molds, diecast tooling involves molten aluminum, Dievar steel blocks, and deep, complex cavities that require both precision and durability. These types of jobs can wear down your tooling, consume too much machine time, and lead to unstable setups — especially when dealing with awkward angles or deep ribs. 

At Rapid Holding Systems, we recently worked on a challenging diecast mold project for a Canadian customer — and it was the perfect example of how the right workholding solutions can completely change your workflow. 

The Problem: Deep Cavities + High-Wear Steel 

This project involved machining Dievar steel blocks — a tough material chosen for its durability under extreme conditions like molten aluminum casting. The mold required deep cavities, tight tolerances, and side-mounted setups for boring mill operations. Conventional fixtures simply wouldn’t offer the stability or flexibility needed. 

The question was: 
How can we safely machine complex geometry into hardened steel blocks, without compromising precision or tool life? 

✅ The Solution: RHS Tooling for Deep and Rigid Setups 

Using Rapid Holding Systems tooling, we were able to set up, machine, and EDM burn this diecast mold block efficiently and precisely. 

Tools used in this project: 

1. 🔧 RHS EDM Extensions 
   These extensions allowed us to burn deep cavities that couldn’t be reached by standard tools. Built for Wire EDM and EDM burning operations, they’re rigid, precise, and designed for difficult geometries. 

2. 🧱 RHS U Holders 
   Our U Holders helped secure the graphite during EDM setup and ensured consistent positioning for critical dimensions. 

3. 🛠️ CNC Pull-Down Units 
   Compatible with FCS and Schunk-style systems, these pull-downs allowed us to side-mount the blocks on the boring mill. With M16 threaded screws and precision-ground spigots, the result was a rigid and accurate setup that could handle both vertical and horizontal machining. 

💡 Why It Matters for Other Machinists 

Whether you’re machining plastic molds, aluminum diecast cores, or high-precision steel components, the right workholding system can save hours of setup time and prevent costly errors. 

By integrating modular EDM extensions, precise U holders, and rigid pull-down clamping systems, your shop can: 

• ✅ Eliminate vibration and deflection during deep cavity machining 

• ✅ Speed up changeovers between setups 

• ✅ Improve repeatability and reduce scrap 

• ✅ Handle tougher jobs with more confidence 

Ready to Upgrade Your Diecast or EDM Setup? 

This project is just one example of how Rapid Holding Systems tools are helping moldmakers, machinists, and manufacturers across North America solve real-world challenges on the shop floor. 

If you’re tackling deep cavity EDM burns, complex diecast molds, or want better setups for your CNC boring mill — we’ve got your back.

For Wire EDM Shops, Setup Isn’t Just a Step—It’s the Foundation 

In Wire EDM, precision isn’t a luxury—it’s survival. Whether you’re cutting aerospace components or delicate medical parts, even the slightest misalignment can wreck tolerances and scrap an entire job. So why are many shops still relying on guesswork when it comes to aligning their chucks and pallet systems? 

The Wire EDM Master Ruler from Rapid Holding Systems offers a smarter way to calibrate your work envelope—accurately, repeatably, and with minimal downtime. 

What It Is (And Why It Matters) 

This isn’t just another ruler—it’s a master reference tool designed for System 3R-compatible setups. Built with a precision-machined indicating face and laser-etched coordinates, the ruler allows machinists to align their chuck and pallet systems to the machine’s wire path with pinpoint accuracy. 

• ✅ Comes in a durable case for protection 

• ✅ Compatible with 70mm 3R-style pallets 

• ✅ Includes an indexed spigot and chuck interface 

• ✅ Etched with X, Y, and Z coordinates for direct offset readings 

If you’re using a 3R-compatible chuck mounted to your EDM rails, this master ruler tells you exactly where your zero-point is—so every fixture, vise, or electrode holder clamped to it aligns perfectly from job to job. 

Why Shops Are Upgrading to Master Rulers 

🔹 You Need Repeatable Accuracy 

Your entire EDM setup depends on knowing where your chuck is. With the Wire EDM Master Ruler, you can quickly thread your wire through the master hole, indicate along the ruler face, and pick up precise offsets without complex macros or manual math. 

🔹 It Speeds Up Your Setup 

The ruler mounts directly onto your chuck and rail system using a fitted spigot. No need to tweak or shim—just lock it in, calibrate once, and go. The quick-spigot interface mimics real production conditions, so what you set up is what you get. 

🔹 It Reduces Scrap and Rework 

By giving you the Z height and XY offsets right from the tool, you avoid part misalignment and tolerance stack-ups. The result? Better first-article accuracy and fewer bad parts on the back end. 

How It Works: Step-by-Step Setup 

1. Mount Your 3R-Compatible Chuck 
   Bolt your chuck directly to your EDM rail system using standard M8 holes. 

2. Insert the Spigot into the Master Ruler 
   Give it a twist—the locking dogs engage and pull the spigot down into the chuck’s seating face. 

3. Lock It In 
   Use the included plastic locking ring to secure the assembly. The ruler is now seated with full XY and Z contact. 

4. Thread Your Wire Through the Master Hole 
   Indicate along the flat face and set your EDM program zero based on the etched measurements. 

5. Record the Offsets 
   With laser-marked dimensions like “X: 9.981 mm, Y: 130 mm, Z: 24.523 mm,” you can now set up your tooling with confidence. 

Who This Is For 

If you’re a Wire EDM machinist, production manager, or maintenance engineer dealing with tight tolerances and setup variability, this is your tool. 

This master ruler is built for: 

• Shops using System 3R-compatible tooling 

• Teams tired of wasting time on manual alignment 

• Anyone chasing tight ±0.005 mm tolerances 

• Facilities aiming to scale production without increasing downtime 

Final Word: The Master Ruler Isn’t Optional—It’s Foundational 

This isn’t a “nice to have.” For shops that run high-precision jobs, a master ruler is essential. The RHS Wire EDM Master Ruler helps you lock in your setup, protect your tolerances, and avoid surprises on the final cut.

Specializing in machining ferrous and non-ferrous metals, they’ve consistently invested in cutting-edge CNC and EDM technologies to stay ahead of the competition. 

But as their operations grew, so did their challenges. 

Their EDM workholding system was slowing them down — causing long setup times, higher scrap rates, and unnecessary downtime. 

They needed a better solution… and they found it with Rapid Holding Systems. 

The Problems Holding Circle 5 Back 

Before working with us, Circle 5 faced three major issues 

1. Inefficient Setup Times 

“We were using manual chucks on the table before, but now we’ve switched over to multiple pneumatic chucks. It’s been a game-changer for us.” 

The old manual chuck system needed constant adjustment, wasting precious machine time and keeping operators focused on setup instead of production. 

2. Inconsistent Precision 

“With the old system, the turret handle would work its way loose, causing inconsistencies. But now… it’s a lot more rigid and repeatable.” 

Loose handles meant parts could shift mid-process — hurting precision and creating costly rework. 

3. Difficulty with Deep & Complex Machining 

“The biggest issue was getting down into deep pockets and small areas. The custom extensions from Rapid Holding Systems solved that perfectly.” 

Standard workholding simply couldn’t handle their deep cavity jobs efficiently. 

The Solution: Pneumatic Chucks + Custom Extensions 

Recognizing the need for a modern, reliable, and scalable setup, Circle 5 replaced their manual chucks with multiple pneumatic chucks from Rapid Holding Systems — and added custom-designed extensions for their most challenging jobs.
