RCGX CBN Inserts

Features

Introduction

The RCGX series Solid CBN insert is a CBN insert developed and produced exclusively by our company. It adopts a 120 °cone positioning to tightly fix the insert and the cutter body to complete the cutting of difficult-to-machine material workpieces. The service life is 5-10 times longer than that of carbide tools and ceramic tools.

This type of insert is used in the finishing of the turntable bearing raceway efficiently, and the grinding is replaced by turning, which improves the efficiency more than 5 times compared with grinding. Cubic boron nitride inserts have extremely high hardness and red hardness, can withstand high cutting speeds, are suitable for ultra-high-speed machining of steel workpieces, and are ideal cutting tools for high-speed machining of hardened steel, chilled cast iron, high temperature alloys and other materials. Because CBN inserts can obtain good surface roughness when machining high-hardness parts, using CBN tools to cut hardened steel can greatly improve machining efficiency while ensuring quality, and has the longest service life in high-speed cutting. Cubic boron nitride tools are suitable for turning and milling of high-strength steel, and are mainly used for semi-finishing and finishing. CBN tools are used for finishing, and the cutting effect is significantly better than that of cemented carbide and ceramic tools.

Advantages

Characteristic	Advantages
1.Widely application	Can meet finishing, semi-finishing and roughing.
2.High fracture toughnes	Continuous cutting, general cutting, and interrupted cuttin
3.High bending strength	Large cutting depth(<1/3 length of insert)
4.High temperature resistanc	Can withstand high temperature of 1400 degree
5.More cutting edges	Unlimited regrind, high blade utilization

Precautions for the use of CBN inserts

1.Polycrystalline cubic boron nitride tools are suitable for roughing and finishing of gray cast iron (iron content is not greater than 10%), alloy cast iron, chilled cast iron, high chromium cast iron, high manganese steel cast iron, quenched steel, surfacing and other workpieces with high hardness.

2.In use, different grades of tool materials should be selected according to different processing materials.

3.Before using the inserts, check whether the blade is installed correctly and the compression is firm, to avoid damage caused by improper compression and positioning of the inserts.

4.Make sure that the inserts are installed correctly on the machine.

5.When the blade is indexed, the sipe should be cleaned to ensure that the inserts and the blade are properly combined, and whether it is normal.

6.Care should be taken to check the sipes, gaskets, and pressure plates frequently, and if they are deformed or damaged, they should be replaced in time.

7.Before machining, it is necessary to chamfer the workpiece with a non-CBN tool.

8.During the cutting process, pay attention to the cutting status of the tool at any time. If abnormality is found, stop the machine and check immediately to avoid unnecessary damage.

9.Do not use CBN tools to cut the workpiece to the end, but leave a small margin for cutting with non-CBN tools.

10.When using CBN inserts, please pay attention to the rigidity of the machine tool, the vibration should be small, and the clearance of each transmission amplitude should be small.
