T-Slot / V-Slot

Guide to Graphics Card Slot Types. Difference between single slot, dual-slot, 2.2 slot, 2.3 slot, 2.5 slot, 2.75 slot and triple slot graphics cards. The height of a graphics card is generally expressed in terms of slot number i.e. Single, dual, 2.5, 2.7, triple. This number specifies the number of slots a graphics card will occupy on a motherboard and probably on the computer case expansion. Hi all, I have recently purchased some 2020 T-slot profiles which are well made with a good finish and was just looking at V-slot prices for comparison. The V-slot is 2-3 times the price, yeah it has a V profile but trying to understand why there is such a price difference? T slot is great for assembly, but will not allow you to run it as a linear guide rail. A v-slot rail is either a single purpose or modified t-slot rail with angled sides In the slot that will let you run a self-centering wheel / guide rail. The T-Slot Block is a new workholding product.now available to make your precision machine jobs faster and easier. The T-Slot Block is a versatile system for workholding having many important features and advantages, such as industry standard T-Slots, and threaded holes for corresponding T-Nut studs or bolts. T-Slots and threaded holes are designed into each T-Slot Block.

T-Slot has been around for many years. It has matured to a solid building system using in industry and by hobby engineers to build everything from machine enclosures to CNC machines, 3D printers and robots! It is strong enough to withstand many industrial stresses and modular enough allow for universal designs.

The T-slot system consists of extruded aluminum of various sizes with a “T” shaped slot on one or more of its sides. The shapes, sizes and designs may be different, but the “T” slot is common to all. The “T” slot allows of a variety of hardware to be connected to the extrusion so that complex structures can be constructed.

Types of T-Slot

There are many types of T-Slot available on the market. Some of the most common for small scale engineering include:

• V-Slot
• MakerBeam
• OpenBeam
• MicoRax

As show above, these 4 type range from 10mm to 20mm square profile. Each profile has its unique features, but all share the “T” slot function.

T Slot V Slot Difference Game

The profiles are not limited to square. V-slot, for example, comes in 4 sizes 20x80mm, 20x60mm, 20x40mm and 20x20mm :

Some manufactures produce larger square and other shaped profiles:

MakerBeam can fit a screw into its T-slot:

MicroRax is small, light and uses t-nuts and screws:

OpenBeam can fit a standard nut into its t-slot:

V-Slot uses t-nuts and is different from the other profiles because has “V” grooves that fit special “V” wheels and allow for easy linear motion:

Above are four different approaches to T-slot, there are in fact many more.

T-slot structural framing is a framing system consisting of lengths of square or rectangular extruded aluminum, typically 6105-T5 aluminium alloy, with a T-slot down the centerline of one or more sides. It is also known as 80/20 framing, after the company 80/20, Inc., one of the prominent T-slot framing brands, the name of which is based on the 80/20 principle. While there is no published standard defining this framing system, manufacturers have settled into two categories of product comprising several series each that is generally intercompatible across manufacturers.

T-slot framing is divided into metric and fractional (imperial) categories. The T-slot is always centered along the long-axis of the piece. Pieces are available in each series with a square cross-section. Rectangular cross sections are available as well which measure x by 2x (where x is the defined width) - e.g. 40mx80mm for 40 series.
