Supporting Bearing Designs With Advanced Machining Solutions


Israel – Bearings are necessary for almost any mechanical system and other items that require rotational motion. Iscar provides comprehensive solutions for bearings applications with efficient tools for parting, trepanning, grooving, profiling and turning operations, the company explains.

Iscar’s turning division provides a large variety of latest geometries and carbide grades as well as ceramic and CBN inserts for finish turning operations of hardened bearing rings up to 64 HRc.

If something, turns, twists or moves, it most likely has a bearing in it. While the most popular bearing type in the market is the ball bearing, roller bearings, needle, tapered, spherical and thrust bearings are also common. Bearings range in size from very small diameters such as 2 mm for electronic systems up to diameters of 6000 mm mostly for wind-power turbines.

When it comes to bearings, one of the most demanding industries today is the automotive industry. Every car has an average of 100-150 bearings, while motorcycles have between 25-30. With an annual production rate of over 93 million cars and 140 million motorcycles a year, the demand for bearings is higher than ever and continues to rise. The need for bearings is also increasing in other industrial sectors such as machine production, electrical appliances, construction and infrastructure machinery, aviation and power generation. According to Iscar, its experienced engineers are capable of supporting any bearing design with advanced machining solutions that can ensure maximum performance, efficiency and precision.

Many Iscar inserts are designed as multi-corner inserts, such as the Penta, and feature economic advantages due to their five cutting edges, the company says. These inserts are mostly used for parting-off operations, seal groove machining and raceway grooving. The unique structure of the Penta inserts enable grinding unlimited numbers of different shapes and geometries with a very attractive cost per edge, so helping customers to reduce production costs and increase competitiveness.

Penta inserts can also be used for trepanning, an axial operation for the separation of one thick forged ring into two separate outer and inner rings. For such operations, Iscar also offers other types of inserts such as BGR and BGMR for wider rings that dictate deep separation operations.

Iscar has also developed multi-parting systems for customers that feature an assembled set of parting blades or adapters designed for parting a few rings at a time. Such sets are provided with the Tang-Grip and Do-Grip inserts, and also with the Penta inserts. Such parting systems dramatically shorten one of the most common operations in bearings production.

Iscar’s unique parting-off products are provided in very narrow sizes that enable manufacturers to significantly reduce the width of inserts, down to 0.7 and 1.0 mm, therefore saving on raw materials, savings that help produce up to 15% more rings out of existing steel tubes, the company explains.

For finish-turning operations of hardened bearing rings up to 64 HRc, the company’s turning division provides a large variety of the latest geometries and carbide grades as well as ceramic and CBN inserts. CBN inserts with chipformers are Iscar’s ultimate solution for such operations and can easily replace expensive grinding processes.

Wide-profiling operations on multi-spindle machines can be addressed with Iscar’s V-Lock and FTB inserts that provide a solution for wide profiles of 10 up to 51 mm width.
