Holding your workpiece securely is essential to a successful project. A common and simple way to hold down a piece is with slotted clamps. You simply place the clamp on top of the workpiece then put the clamp screw through the slot. The M3 has a grid of sixteen points for fastening while the Carve King uses T track extrusions. It is cnc router edge clamps limited to have a shim piece on the backside of the slotted clamp approximately equal to the thickness of the material.

Examine the workpiece prior to clamping it down. Many workpieces will have some bow before you even clamp it. With this method, you should put the convex side face down, so the edges are raised up from the surface.

The clamps help pull the bow out. This video of the Power Route cutting aluminum shows the top clamping method in practice. We include a set of water jet cut slotted aluminum clamps with every machine bundle that we sell. Cons: Can actually add bow to the material depending on how it is clamped. Limited access to edge of stock. Heavy cuts can push the workpiece. Edge clamping is cnc router edge clamps limited less commonly used method, but still should have a place in your workholding toolbox.

This method involves applying pressure to the part from opposing sides in a similar way that a vise holds stock more on vises in a moment.

There are a couple ways to achieve this. You could make yourself some toe clamps, as described in this Instructable. We have eccentric spacers if you want to build some of the clamps described there. Another inexpensive edge clamping solution is to use blocks and wedges. You can find files for them here and cut them yourself. With blocks and wedges, you simply fix one block in place, then slide the stock up to it. On the opposite side, you fix another block to the table and leave a little space for the wedge to get between your stock and the block.

You then press or gently tap the wedge in with a mallet. Cons: Can add bow to thinner or less sturdy material. Less secure than vise workholding. Vacuum clamping is one of the most mesmerizing and effective methods. Everything around you is exposed to about What if instead the work piece is 10 inches by 10 inches? The hold down force increases to 1, pounds! Some vacuum systems require a large vacuum pump, but our vacuum clamping system uses your air compressor to generate vacuum with a venturi vacuum generator.

Just arrange the gasket material in the vacuum plenum to match the shape of your part, put on your work piece, cnc router edge clamps limited turn the valve on the venturi vacuum generator. Pros: Very quick to cnc router edge clamps limited parts on and off. Sucks material completely flat. Generates an extreme amount of holding force. Allows full access to the top of the work piece. Cons: You can cut all the way through your material, but you need to be strategic about where your gasket material is placed relative to the profile.

Alternatively, you could leave a few thousandths of an inch of material at the bottom so as not to break the vacuum seal. A vise is commonly used in metalworking on industrial mills, but this may be the best way to hold a piece you are cnc router edge clamps limited too.

The challenge in CNC router applications is using a vise that is low profile enough to allow gantry clearance. An added bonus of using a vise is that you can designate the corner of the fixed jaw of cnc router edge clamps limited vise as an origin of a work coordinate system if you have homing switches Side note: See this video for everything you wanted to know about work coordinate systems.

This will allow you to perform repeated work quickly. Pros: Immense amount of holding force. Very quick to clamp and unclamp work. Allows full access to top of work piece. Cons: Only relatively smaller pieces can be held. Thinner or weaker materials will surely bow or collapse. Direct fastening is just cnc router edge clamps limited it sounds like. You simply screw the stock down directly. You can run a cnc router edge clamps limited screw through your material and into your spoil board or you can pre-drill the stock and run machine screws or bolts through the material and fasten it to the table directly.

I sometimes use this method in conjunction with another. Allows you to profile the outside of a piece if edge clamping or top clamping would interfere. Cons: Can take longer than other methods to set work up. You must plan your cut paths not to collide with any screws placed within the cut boundaries.

Double sided tape is a favorite method among home PCB fabricators. You must clean the bottom of the work piece as well as your table or spoil board cnc router edge clamps limited make sure it sticks. Pros: Flattens out thin work pieces such as printed circuit boards. Allows access to the entire top side of work piece. Cons: You will be left with adhesive residue that needs to be cleaned up. Does cnc router edge clamps limited always provide a firm hold down.

A closely related method is to use painters tape and super glue. You start by cleaning both the table or spoil board surface and the workpiece surface. The surface should be free of dirt, burrs, and debris. Apply blue painters tape to each surface. Use wide tape. Use a putty knife or straight edge to remove any air bubbles and completely flatten the tape.

Apply a quality superglue to one side and press the work piece cnc router edge clamps limited to the table. Hold it down with your own pressure for about a minute as the glue sets. You may want to put a weight on top of the work piece for a couple more minutes as the glue further sets. Pros: Provides a very firm hold. Flattens out bowed pieces. Cons: Can take a little while to set up. Potentially messy.

Can be hard to get the material back u p. In many workholding cases, there is no right answer. There Cnc Router Low Profile Clamps Zoom is usually a wrong answer though.

Each method has its place. Be sure to try a few of the different methods to see what works best for you in each situation. Great info.

I work in wood only and primarily use the top clamp and painters tape superglue methods. Thanks Great info, however you have missed the one I use regularly. I fix a sacrificial board to my cnc bed, Plane it flat, clamp and then attach my wood blank to the board using hot melt glue around the edges of the blank. The advantage of using hot melt glue is that it is quck and you can easily destroy the glue bond using methylated spirit. The other advantage is that if the tool overruns the piece there is no clamp to damage your cutter.

Hot glue works to clean debris off magnetic surfaces too really well. While some people cut ferrous metals with our machines, they are often left to heavy mills. Our machines are for woods, cnc router edge clamps limited, plastics, and softer metals like brass and aluminum. To your point though, you can embed magnets in the spoil board and clamp thinner materials with good magnets by laying magnets on top of the material, over where they are embedded in the spoil board.

What methods do you use Jim? I came to this website at the invitation of an email, and not knowing what MillRight sells. I have used a magnetic chuck on our old, tired, manual Bridgeport mill, when cutting steel. Of course I put a very thin spoil board under the work.

Sometimes I use top clamps, other times, I use heavy weights to hold the thin sheets down. I think the suggestion of superglue and painters tape, and hot glue are good ones. The cnc router edge clamps limited on yellow banners and buttons do not show up good on my browser. At least not to cnc router edge clamps limited old eyes.

Thank you for the discussion Derek. I have been using the edge clamp setup holding down a spoilboard Cnc Router Clamps Hold Down 80 then screwing the workpieces directly to the spoilboard with great success. Getting there….
