How to support the Upper X Beam

This article explains how to support the Upper X Beam when using a small piece of stock material.

< Previous | List | Next >

Why does the Upper X Beam need support?

SmartBench needs to consistently clamp the material between the rollers of the Lower and Upper X Beams throughout the job. 

Click here to learn more about material clamping technology, and why it is important.

A - Stock material

B - Spoilboard

C - Upper X Beam rollers

D - Lower X Beam rollers

If an offcut sheet material is only just big enough to accommodate the job, the Upper X Beam rollers will move away from the surface of the material during machining. 

In this case one side of the Upper X Beam will not be supported, and the X Beam will no longer be fully clamped around the materials. 

Methods for supporting the Upper X Beam

To support the Upper X Beam rollers throughout the job, ensure that there is always some supporting material that sits under the rollers, and extends a minimum of 70 mm from the job boundary along the Y axis. 

You can achieve this by:

  • Choosing a larger sheet of stock material

  • Adding support tracks around the stock. 

Choose a larger stock material

Ensure that the stock has an extra 70 mm of material either side of the job boundary, along the Y axis. 

E: Cutting area

F: Minimum stock size

Add support tracks around the stock material

It is still possible to use the same stock material, provided it is used with additional pieces of support material. These additional pieces of support material will form tracks for the Upper X Beam rollers.

The thickness of the tracks must be at least the same as that of stock material, or up to 6mm thicker than stock material. The track material must be flat and hard to prevent the Upper X Beam rollers digging into it.

The length of the support material along the Y axis must be at least 70 mm longer than the stock material on both sides to continuously support the Upper X beam, and wide enough to accommodate the rollers. 

G: Additional support material 

H: Stock material

During set up, adjust the Upper X Beam rollers so that they run on the tracks.
