Waterjet Cutting for Machine Shops

Expand Capacity, Cut Any Material, and Handle Every Customer Demand

In a modern machine shop, success depends on versatility, rapid turnaround, and the ability to handle whatever drawing or material a customer sends through the door.

While traditional CNC milling, turning, laser, and plasma systems excel at specific tasks, relying solely on them can limit the jobs you can accept. Thermal distortion, hard-to-machine metals, thick plates, or long lead times from external suppliers often create unnecessary bottlenecks.

Integrating an in-house waterjet cutting system gives machine shops and job shops an extremely versatile edge. From cutting quick one-off prototypes to prep-machining near-net shapes, waterjet technology delivers cold-cutting capability for virtually any material without changing tooling or risking thermal damage.

Why Machine Shops Choose Waterjet Cutting

Machine shops face constant pressure to adapt quickly, reduce lead times, and maintain profit margins on short production runs. Waterjet cutting addresses these core operational challenges by streamlining how material enters your workshop.

Unmatched Material Versatility: Cut everything from aluminum, steel, and titanium to copper, composites, glass, and rubber on a single machine.
Eliminate Thermal Distortion: As a pure cold-cutting process, waterjet cutting creates zero heat-affected zones (HAZ), eliminating material warping, structural hardening, or edge discoloration.
Zero Dedicated Tooling: Transition from one customer drawing to the next in minutes using digital DXF or CAD files without investing in specialized cutting tools.
Streamline Existing CNC Workflows: Use waterjet systems to quickly cut near-net blanks, reducing roughing times, tool wear, and material waste on your CNC mills and lathes.

Expand Your Service Offering and Accept More Jobs

When your machine shop can handle any material and complex geometry, you never have to turn away high-margin customer requests.

Adding waterjet capabilities allows you to accept custom parts, intricate internal cut-outs, tight-radius contours, and thick-plate components that would be too slow, costly, or difficult to process using conventional milling or thermal cutting methods.

Whether producing specialized industrial components, repair parts, or architectural brackets, one waterjet machine enables your shop to win business that previously went to competitors or specialized external vendors.

Complete Cold-Cutting Capability Across All Materials

Different customer projects demand different materials. Waterjet Sweden systems handle both hard and soft substances with ease using two primary processes:

Abrasive Waterjet Cutting

For hard materials, natural garnet abrasive is introduced into the high-pressure water stream. This enables rapid, clean cutting through dense metals and hard substances, including:

Structural & Alloy Steels: Carbon steel, stainless steel, tool steel, and hardened armor plate.
Non-Ferrous Metals: Aluminum, titanium, brass, copper, and bronze.
Hard Non-Metals: Glass, stone, ceramics, dense composites, and carbon fiber.

Pure Waterjet Cutting

For soft, flexible materials, pure high-pressure water cuts at supersonic speeds without abrasive additives. This provides razor-sharp edges and fast processing for:

Plastics
Rubber
Foam
gasket materials
Insulation
Thin laminates

Reduce Lead Times and Take Control of Production

Waiting days or weeks for external laser, plasma, or waterjet suppliers delays job completion and hurts customer satisfaction. Bringing waterjet cutting in-house transforms your responsiveness.

Immediate Job Execution: Load drawings and start cutting parts the moment an order or revision arrives.

Fast Emergency Turns: Accommodate urgent customer repair jobs or rush orders without disrupting main production schedules.

Seamless Drawing Revisions: When customer specifications change mid-project, update the digital cutting path instantly—no scrapped custom tooling required.

Ideal for Prototypes, One-Off Parts, and Small Batches

Job shops often struggle with the setup costs associated with short production runs. Waterjet cutting excels in prototype and low-volume environments because it relies entirely on software-driven parameters.

Because the cutting stream exerts minimal mechanical force on the workpiece, clamping requirements are simple and fast. Engineers and machinists can cut a single prototype, verify dimensions, adjust the CAD file, and cut a modified version in a fraction of the time required by traditional methods.

Precision Custom Work and Complex Geometries

Waterjet cutting handles delicate features, sharp corners, narrow slots, internal cut-outs, and hole patterns across varying material thicknesses.

Whether cutting 0.5 mm thin sheet metal or 200 mm thick solid alloy plates, the process maintains consistent edge quality without mechanical chatter or tool deflection. This makes it ideal for project-specific components that require complex contours.

Complementing Your Existing CNC, Laser, and Plasma Machines

A waterjet system does not replace your existing workshop machinery—it makes your entire facility more efficient.

The Waterjet Pre-Machining Workflow

Raw Material Preparation: Load full-sized metal plates, sheets, or blocks onto the waterjet table.
Cold-Cutting Near-Net Shapes: Rapidly cut out complex outer contours, weight-reduction pockets, and internal openings with zero heat damage or material hardening.
Optional CNC Finishing: Move the pre-cut blank directly to your CNC mill, lathe, or drilling center only for high-precision finishing features like tapped holes, close-tolerance bores, or critical mating surfaces.

How Waterjet Compares to Other Technologies

Versus Thermal Cutting (Laser & Plasma): Waterjet cuts thick plates and non-conductive or highly reflective materials (copper, brass, stone, glass, composites) without heat damage, edge hardening, or toxic fumes.
Versus CNC Milling: Instead of spending hours machining away massive amounts of solid block material, rough out complex blanks on the waterjet in minutes, dramatically reducing milling time, tool wear, and scrap material.

Edge Quality and Precision Tailored to Your Needs

Precision and edge finish in waterjet cutting are entirely controllable based on target application, material type, thickness, and speed.
Raw / Separation Cut: Fast cutting speed for rough blanks, weld preparation, or parts receiving secondary machining.
Standard Industrial Cut: Balanced speed and finish suitable for most structural components, brackets, and general job shop work.
Fine / Precision Cut: Slower cutting speed delivering smooth edge surfaces with minimal taper, often eliminating the need for post-processing entirely.

Selecting the Right Waterjet Configuration for Your Workshop

Every machine shop operates differently. Choosing the right waterjet machine depends on your typical workpiece sizes, material mix, and output goals:

Table Size & Footprint: Compact machines fit tighter workshop spaces, while larger gantries accommodate full-sized raw sheet stock to reduce pre-cutting material prep.
Multi-Head Configurations: Increase throughput on recurring small-batch runs by cutting multiple identical parts simultaneously.
2D vs. 5-Axis & Bevel Cutting: Standard 2D systems handle flat sheet and plate work, while 5-axis heads enable beveling for weld preparation or taper compensation on thick parts.
Micro Waterjet Cutting: Designed specifically for high-precision miniature components, narrow kerf widths, and tight tolerance medical or instrument manufacturing.

Maximize Profitability and Lower Outsourcing Costs

Investing in an in-house waterjet machine directly impacts a machine shop’s bottom line:

Eliminate Vendor Markup: Keep profit margins in-house rather than paying third-party cutting services.
Optimize Material Usage: Advanced nesting software packs parts tightly together on raw plates, reducing material waste on expensive alloys.
Eliminate Bottlenecks: Control your production schedule from raw stock to finished delivery.
Win Higher-Value Contracts: Offer single-source solutions to customers who require fast turnaround on multi-material assemblies.

Why should machine shops invest in waterjet cutting?

Machine shops should invest in waterjet cutting when they need more flexibility, shorter lead times and the ability to cut a wider range of materials. A waterjet machine can support customer-specific parts, prototypes, one-off jobs and short production runs without dedicated tooling.

For job shops that handle many different customer requests, waterjet cutting can make it easier to accept complex jobs, reduce outsourcing and respond faster when drawings, materials or deadlines change.

What materials can a machine shop cut with a waterjet machine?

A waterjet machine can cut many different materials, depending on the machine configuration and cutting process. Common examples include steel, stainless steel, aluminium, titanium, copper, brass, composites, glass, stone, ceramics, plastics, rubber and foam.

Hard materials are usually cut with abrasive waterjet cutting, while softer materials can often be cut with pure waterjet cutting. This makes waterjet technology useful for machine shops that work with many material types and customer applications.

Is waterjet cutting suitable for prototypes and one-off parts?

Yes, waterjet cutting is well suited for prototypes and one-off parts. The process is digitally controlled and does not require dedicated tooling, which makes it practical for early-stage designs, test parts and small batches.

This is useful for machine shops that support product development, engineering projects, repair work or customer-specific components where fast turnaround and design flexibility are important.

Can waterjet cutting help machine shops reduce lead times?

Yes, waterjet cutting can help reduce lead times by bringing more cutting capacity in-house. Instead of waiting for external suppliers, machine shops can cut parts directly from digital drawings and respond faster to customer needs.

This can be especially valuable for urgent jobs, short runs, prototype work and projects where dimensions or drawings change during the process.

How can waterjet cutting expand a machine shop’s service offering?

Waterjet cutting can expand a machine shop’s service offering by making it possible to cut more materials, more shapes and more customer-specific parts. It can be used for flat parts, complex contours, holes, slots, internal cut-outs and detailed geometries.

By adding waterjet cutting, machine shops can take on jobs that may not be suitable for laser, plasma, milling or other existing processes. This can create new business opportunities and support more varied customer requirements.

Can waterjet cutting replace outsourcing for custom cutting jobs?

In many cases, yes. A waterjet machine can help machine shops handle more custom cutting jobs internally, especially when external suppliers create long lead times, high costs or limited flexibility.

Whether it can fully replace outsourcing depends on material types, part sizes, thicknesses, tolerances, production volumes and the machine setup. For many machine shops, waterjet cutting becomes a way to reduce outsourcing and keep better control over customer projects.

How does waterjet cutting compare with laser, plasma and CNC machining?

Waterjet cutting is different from laser and plasma cutting because it is a cold cutting process. It does not create heat-affected zones, thermal distortion or heat-related changes along the cut edge.

Compared with CNC machining, waterjet cutting can be an efficient way to cut near-net shapes before additional machining. It can also be useful for materials or geometries that are difficult, slow or expensive to process mechanically. In many machine shops, waterjet cutting works best as a complement to existing machining, laser or plasma capabilities.

Can waterjet cutting be used before milling or other machining processes?

Yes, waterjet cutting can be used before milling, turning, grinding or other machining processes. It can cut blanks, contours and near-net shapes that are then finished with other production methods.

This can help reduce machining time, remove less material in later stages and make the production workflow more efficient. It is especially useful when parts need accurate outer contours before final tolerances, surfaces or features are machined.

What type of waterjet machine is best for a machine shop?

The best waterjet machine for a machine shop depends on the type of jobs, materials, part sizes, thicknesses and production volumes. Some machine shops need a compact and flexible system for varied customer work, while others need a larger working area, higher capacity or more advanced cutting options.

Important factors include table size, pump capacity, cutting head setup, abrasive handling, software workflow, precision requirements and whether the shop needs 2D cutting, bevel cutting, micro cutting or 5-axis cutting.

What should machine shops consider before choosing a waterjet machine?

Machine shops should consider the materials they want to cut, the thickness range, part sizes, tolerance requirements, expected production volume and how the machine will fit into the existing workflow.

It is also important to think about software, operator training, abrasive handling, service needs, available floor space and whether the machine should support prototypes, recurring production, urgent jobs or a wide variety of customer-specific parts.
