Floating reamer holders are used on machine tools such as single-spindle lathes, multi-spindle lathes, NC machines, CNC milling machines, drilling machines, and transfer machines. They are mainly used for floating reamer holder lathe operations and can also be used for rigid tapping. Free movement between the two axial bearings allows the reamers to follow an existing drilled hole, ensuring high-quality work.
Additionally, they can be supplied with a vise taper adapter, metric and inch cylindrical shaft adapter, and VDI adapter. Quality floating reamer holders are made of certified steel of the highest quality, they are hardened and completely ground. The floating holder of the reamer is adjusted with minimal axial play and the reamer play is provided by radial vibration. To keep the floating reamer holder centered, the tool holder is equipped with a self-centering mandrel that is pressed against by a spring that can be adjusted according to the size of the reamer mounted.
Reaming is a cutting operation with a multi-edge cutting tool that is constantly in action. Reaming is used to finish the drilled holes exactly to size and with a good surface finish. Reaming with floating reamer holders has the advantage that a greater number of holes of consistently good quality can be made. This requires a cutting tool reamer that has the exact diameter required and the correct edge profile (lead, straight/spiral, and tapered reamers) and is well sharpened on the top. Reaming requires a hole that has been thoroughly pre-machined with good rotational accuracy and sufficient machining allowance. The reamer uses specialized equipment to make a hole to precise specifications. Unlike flexible bits, the reamer is designed to produce holes of near-perfect concentricity.
Floating reamer holders are typically used to gradually widen the initial hole created by drilling. Instead of drilling the entire hole all at once, which can cause inconsistencies and tearing. The reamer gradually expands and forms the shape of the workpiece to suit your high demands, and the use of lubricants will extend the life of the tool. Reaming is used for both countersunk and tapered holes.
There are hand reamers and machine reamers. They vary mostly in terms of the shank and the cutting part. Hand reamers are primarily used for assembly work to make the pieces match properly. Its key feature is a long, conical lead. This ensures a strong direction of the floating reamer holder in the hole and avoids warping. By turning clockwise and applying light friction, the reamer is inserted into the hole using a milled square and a tap spanner. The system reamers used for the lathes include non-adjustable reamers, mandrel-mounted reamers, adjustable reamers, spiral grooved reamers, and conical reamers.
Adjustable Reamers and arbor-mounted reamer holders are primarily used for the reaming of multiple holes in one set-up and greater volumes. Helical reamers are used for fluted holes and taper reamers for taper holes. Machine reamers are used for the reaming of drills and floating reamer holder lathes. They're guided through the working spindle. Therefore, the lead does not have to be as long as the hand-held reamers. When reaming, the cut is made with lead, while the straight part is used to smooth the hole. To avoid vibration on the workpiece surface, the reamers have uneven tooth spacing. This avoids vibrations and produces exactly round holes. The even number of cutting edges allows the dimensions to be checked on opposite sides.
Of course, even a reaming tool within a floating reamer holder has a margin of error. The lathe tailstock and main axis must align so close to 0.0002 inches for an accurate hole otherwise there may still be scarring and oversizing. The high-quality floating holders of the reamers use free-moving axial bearings to allow them to follow an existing hole with incredible precision. These reamer holders use the latest precision engineering and high-quality steel to ensure long-lasting performance in industrial applications. You can make the most of your reaming tool lathe operations and by investing in a floating reamer holder. Any workpiece that requires a precise, consistent hole in metal or wood can benefit from a floating tool holder reamer.
If you are using a reamer without a floating reamer holder, you are sacrificing precision and overall quality of work. Look for signs of tear, oval, and other reamer issues to determine if you need a floating reamer holder. H. A damaged tool holder will prevent the reaming tool from following accurately in the hole. The most common sign of damage to a tool holder is the inefficiency of the workpieces. Invest in repair services before you need to replace the tool holder or reaming tool. Even the best tool holders require repair or replacement, so watch out for signs of wear on your existing tool holder.
