The CNC machine has many more features which differentiate it from the list of other machines falling in the same price range. But are those features enough to make this machine a valuable one when compared to the price at which it is offered? Well, we can only tell after giving it an in-depth look. So, let’s get started.


Apart from the two of the most noteworthy features mentioned above, HD4 also has a new touch-screen pendant controller which makes users’ overall interaction more interactive. An auto-alignment function with X and Y homing capability makes things a lot easier even for beginners.

Moreover, some users really appreciate how the machine is compatible with commercial routers and carve metal with other materials. Also, it offers a relatively large workspace permitting users to take projects of varying sizes. Below mentioned and explained are some of the most striking features of the machine.

Huge Work Area

HD4 houses a huge work area i.e., 25 inches * 25 inches * 7 inches which is almost four times that of the standard X-Carve model offered by the company.

This is a really massive workspace that opens up a lot of probabilities in terms of the variety of projects that can be done on the machine. As a user, you can cut more parts from larger workpieces, make complete size designs, and even carve panels on a single screen.

Capable of Cutting Various Materials

The machine features a rigid interlocking aluminum table as well as a robust gantry. Also, the overall structure of HD4 includes thick steel shafts, lead screws, and adjustable bearings that give it the required stability during heavy cutting.

Because of such an arrangement, you can use the machine with large routers that are meant for commercial use. HD4 is capable of carving and machining a wide variety of projects that include processing materials like hardwood, laminate, soft metals like aluminum and plastics.

Easy to Use Interface

The CNC Shark HD4 is offered with a handle control in the form of a touch screen pendant that is extremely convenient as it not only eliminates the need of connecting with the computer but also saves space.

A simple user interface makes the machine easy to use. Users can operate the complete machine using the pendant. You can toggle it manually up, down, near, right, or left.

Moreover, you can set the X and Y homing position and also stop the movement of the gantry as well as the spindle from the pendant in case anything goes wrong. The overall operation of HD4 is simple.

Equipped with Separate Spindle Controller

The unit doesn’t plug into the CNC controller. It has an appearance like that of a UPS with an LCD screen and some buttons. Using it, you can adjust the spindle speed and change the format or measuring unit of the speed.

After doing the tool change, it is able to tell you which tool you are using. Moreover, as soon as the machine completes the first tool path after the pocket tool path is done, it returns the spindle to its starting position.

First Impression

CNC Shark HD4

The first thing that strikes out when you get to see the construction of the Shark HD4 is its rigidity and stability. The machine has a heavy-duty gantry made from a thick aluminum plate and polyethylene while the bed is from an equally thick extruded Aluminium featuring multiple grooves for attaching clamps.

One can say that the machine manufacturer has learned from the downside of its previous models. HD4 has a sturdy as well as stable setup design that reduces wobbling as well as backlashing, which was a problem with its predecessors, specifically when carving metal as well as other slightly hard materials.

The heavy-duty stepper motors control overall movement on all three axes. Also, they drive the threaded lead screws that are equally thick and durable. Moreover, the movement is guided using adjustable linear bearings that are on heavy steel shafts.

HD4’s overall construction is quite stiff and capable of providing a great amount of stability while cutting. It is equipped with Next Wave Automation T30506 water-cooled spindle that features ER-11 collet framework allowing users to either use 1/8 inch or ¼ inch shark bits.


The complete unit is relatively easy to set up. All that you have to do is work a little bit on:

  • Attaching the gantry to the base
  • Mounting the router
  • Attaching the pendant
  • Calibrating the bed

After performing these steps, the final step is to register the machine on its manufacturer’s website. That’s it! You are ready to go hereafter.

CNC Machining Quality

CNC Router

HD4 delivers outstandingly accurate parts and functional prototypes, specifically when accompanied by the 3D carving module.

The NWA 3D digital touch probe – a 3D duplicator that you employ to scan or trace a 3D image and either duplicate or reproduce the object to the tiniest details can duplicate an object down to around 0.001-inch detail.

Such a high accuracy makes the machine perfect for cutting out intricate shapes or doing projects that are detail-sensitive like carving/engraving a custom circuit board. Above all, the machine delivers great results with other complex projects like carving inlays and corbels from plastics, wood, or soft metals.


Although the machine does not come along with separate CAM software, it is paired with VCarve Pro design software along with Vector Art 3D sampler pack. Note that, the former one provides more features than most other CAM software, that’s relatively more than what average users will ever need.

It permits users to cut not only in 2D but also in 3D and has powerful drawing tools with hundreds of clip art files enabling you to come up with the design of the part or project you wish to, right from scratch. The program also includes the virtual zero function that assists for twists and warps in the workplace as well as the table.

Having stated so, the application does take some effort in understanding and master it. But, the instructional videos and tutorials are available to guide you through the complete process. Also, the software is compatible with 3D modeling programs such as SketchUp.

Customer Support

In case you face any issue with the machine, getting customer support from the manufacturer is not a hassle at all. There are multiple ways in which you can reach out to them, two of the most common ones being:

  • Via website
  • Via phone

The team is always quick to respond. Apart from this, the company has a very active and supportive community including their own shark forums where users can access information.
