Instruction Manual BARRIQUAN [ C-FSB01 ]

Instruction Manual (Web Manual) of BARRIQUAN BRQ-TX01 for back burr removal, a tool holder for deburring with floating mechanism.

A conical carbide rotary bar with a tip angle 90° is recommended.

Use of spherical cutters will shorten the life of the tool due to forces that prevent it from floating.

A cutter with a large number of blades is preferable for float processing.
Fewer blades will deteriorate the finished surface.

• Use a flare nut wrench (3-point support) to screw in the collet.
• Using a spanner (2-point support) to screw in the collet causes deflection of the tool and affects the finish of the working surface.
• Attach the tip tool to a φ6 collet (spanner size 10, 13).
• The tightening torque of the collet is 6 N･m.

Although the entrance area is one of the most difficult areas with float deburring, you can obtain stable deburring surface with high spindle speed.

The guideline ratio of spindle speed (min^-1) and feed speed (mm/min) is approx. 1 : 0.3 – 0.6.

Higher spindle speed enables higher feed speed.

Smaller deburring cuts can be obtained at higher spindle speeds.

Set the offset amount to 4.5 mm for the cutter C-BF01 (made by Sugino Machine) for back burrs as a guide.

Set the compression amount from 1 to 4 mm as a guide.​

For ferrous materials, the minimum chamfer width is 0.1 mm and the maximum is approx. 0.4 mm.

For nonferrous materials (such as aluminum A5052), the minimum chamfer width is 0.2 mm and the maximum is approx. 0.8 mm.

Soft materials tend to have large chamfer widths.

If runout occurs when installing the tool, the chamfer width will increase.
Set the tip runout accuracy of 0.01 mm/rev or less when processing smaller chamfer widths.

First, use the Spring (medium) assembled in the main body for processing.

If you want to increase the chamfer, replace the Spring (heavy).
If you want to make the chamfer smaller, replace the Spring (light).

Create a Tool path so that a down-cut is performed.

Replace the tip tool with a new one when the blade is chipped or cutting power is significantly reduced.

• Be careful to avoid deformation of the two-sided portion of the Floater when attaching/removing the tool. If the Floater is deformed, the extending/contracting mechanism may not operate properly.

Replace the Spring after 100,000 cycles.
Coil springs lose tension after prolonged use.
