Description

Carbide Bars

Rotary BarRotary Bar

Carbide Rotary Bar

The carbide rotary bar can be used to attach to tools such as small manual grinders, precision grinders, pen grinders, etc.Unlike disc grinders, this hand grinder features a cutting tool that attaches to the tip is not a disc.

The tip of the carbide rotary bar has a variety of shapes, and is mainly suitable for a wide range of processing, such as deburring, heavy grinding, and finishing.In addition, it is compatible with both metal and non-metal, and depending on the product, it is possible to process materials that are difficult to cut like stainless steel. In addition to the product material, the edge shape of the blade is also available in a variety of sizes and groove depth, uneven patterns, and sizes, so you can select the material and processing purpose.

Blade shape of carbide rotary bar

Carbide BarsCarbide Bars

6 popular choices.

The blade shape of the carbide rotary bar has several types, each has different characteristics.It is important to select the shape of the blade and the length of the blade to match the shape and processing area, and the shaft diameter that fits the grinder to be installed.ps: A rotary bar with a shaft diameter of 0.2 - 0.6 inches (6 - 16 mm). The blade shape of the carbide rotary bar has the following shapes.

Note:

Incorrect use of carbide rotary bars can cause rough finishes, scratches to unintended parts and damage rotary bars causing unexpected accidents and injuries.Be sure to pay attention to the following points when installing and working on rotary bars.

Shank protrusion is minimum.

The distance between the grinder body and the rotary bar blade the larger the shake and more difficult to control.As a countermeasure, the main point is to insert deep into the shank to ensure that the protruding length of the shank (shaft).

Normally, 2/3 of the overall length of the axis should be inserted into the collet section of the grinder.By inserting the shank deep into the shank, it prevents the core-shaking and the shank from being warped.

Do not press too much during processing.

Avoid using rotary bars to hold onto material during processing.The rotary bar shavings by rotating the blade, so there is no need to press hard on the material.

Too much pressure may cause the shank distortion of overheating, oscillating the shank, chipping of the blade, and the head will fall off.

Processed with a suitable rotation speed according to the material.

The rotation speed can be adjusted according to the blade diameter of the material you are processed and rotary bar for stable processing.Too slow rotation will lead to cutting power loss and blade chipping, and too fast will lead to heat failure.

When processing materials with low thermal conductivity such as stainless steel and titanium alloys, the speed of rotation is slower.

Please be careful on surfaces that come into contact with.

If you attempt to make a process where 1/3 or more of the circumference of the rotary bar touches the material, the cutting resistance of the rotary bar is increased, and the phenomenon of the blade is prone to bouncing, called tapping.Tapping can not only damage the product, but also damage the rotary bar.

Especially when machining with a cylindrical or spherical tip, or conical V-groove processing, the two sides contact the material at the same time, making tapping easier.Avoid making it as much as possible as possible that two points contact at the same time.

Avoid using for machining.

The carbide rotary bar (bar) is designed and manufactured as a manual tool.Due to the looser tolerance compared to other drill and end mill tools, such as blade diameter, blade length, shank diameter, and total length, it is not recommended for machining using a machining center.
