Reaming allowance is the size of the depth of cut reserved for reaming. Usually, the reaming allowance is smaller than the reaming or boring allowance. Too much reaming allowance will increase the cutting pressure and damage the reamer, resulting in the roughness of the machined surface. When the allowance is too large, the coarse hinge and the fine hinge can be separated to ensure the technical requirements.

For example, if the speed of the drilling spindle is 500r/min, it is reasonable to set the speed of the reaming spindle to 2/3 of it: 500*0.660=330r/min

There is an experience that recommends setting a thickness of 1~3% of the diameter of the reamer as the reaming allowance (diameter value). For example, a reamer of Φ20 and a hole diameter of about Φ19.6 are more suitable: 20-(20*2/ 100)=19.6 For hard materials and some aerospace materials, the reaming allowance is usually made smaller.

Each element of reaming amount has an effect on the surface roughness of the reaming hole, among which the reaming speed has the greatest influence. For example, reaming with a steel reamer should have a better roughness Ra0. It is said that the reaming speed should not exceed 5m/min, because it is not easy to generate built-up edge at this time, and the speed is not high; and when reaming cast iron, because the chips are broken into granular, no built-up edge will be formed, so the speed can be increased. to 8~10m/min. Usually the spindle speed of reaming can be selected as 2/3 of the spindle speed of drilling on the same material.

Smooth finishes on your new tools are fundamental for customer satisfaction and overall tool quality. When you work with a weaker material such as steel, there can be unevenness and inconsistency in the cutting bit, resulting in an uneven finish. By working with an experienced machinist who knows which size diameters to use and a high-powered material like tungsten, you will receive shiny, even and perfect tooling solutions. Manufacturing companies know the value of using consistently aesthetic and robust tools, which is another reason so many of them prefer to work with carbide.

For standard steel reamers to process steel parts, to obtain surface roughness Ra0.63, the feed rate cannot exceed 0.5mm/r, and for cast iron parts, it can be increased to 0.85mm/r.

The so-called reamer is actually boring. The fine boring usually has a unilateral allowance of 0.03-0.1, and the speed is 300-1000. The feed rate of 30-100 is suitable.

On the other hand, if the blank allowance is too small, the reamer will wear prematurely, it will not cut properly, and the surface roughness will be poor. Generally, the reaming allowance is 0.1~0.25mm. For larger diameter holes, the allowance cannot be greater than 0.3mm.

The feed rate of reaming is larger than that of drilling, usually 2~3 times. The purpose of taking a higher feed rate is to make the reamer cut material rather than friction material. However, the roughness Ra value of the reaming hole increases with the increase of the feed rate. If the feed rate is too small, the radial friction will increase, and the reamer will wear quickly, causing the reamer to vibrate and roughen the surface of the hole.

Carbide is the superior material. Technicians can work this tool faster, for a more extended amount of time, at higher temperatures and without breakage. The longevity will be extended if you work with a highly skilled CNC machinist who knows their way around the material and machine. Typically tungsten carbide can be more expensive than its counterpart competitors, but you get what you pay for. Instead of having to replace tool parts or get them fixed, when you buy carbide, you are purchasing an excellent long-term investment for your business.

One of the top reasons so many manufacturers and businesses choose carbide is its longevity. A carbide tooltip will last 20 or 30 times longer than a tip made with an alternative material. Manufacturers need to depend on their machine parts and crafting tools. Whether it is an automotive or aerospace manufacturing business, they need to trust their tools with last. Having to repair parts of a machine on a temporary basis can be costly and time-consuming. Carbide retains its strength and has an overall longer tool life. Steel and other materials do not have the same elemental components and therefore break and chip much easier than carbide.

Our technicians have considerable expertise in crafting and distributing custom carbide tools for manufacturers. Contact us today if you are a newer manufacturing business or a seasoned owner looking to find a new tooling solutions company. We would love to discuss the advantages of working with us and carbide.
