In doing so it has extended its comprehensive range of turning inserts. The grade incorporates the company's state-of-the-art coating technology that provides outstanding wear resistance, as well as a product that improves productivity and usability. At depths of cut up to 0.8mm and at cutting speeds up to 250m/minute means a wide range of applications can be covered by a single grade. This brings a simplification of choice for the production programming and reduces inventory costs. The new line of inserts deliver a variety of performance and benefits through constant refinement and R&D work. This has created a new sintered substrate containing both micro and medium grain CBN particles, but with an ultra micro-particle binder. This new binding technology in the substrate offers high heat resistance and prevents sudden fracture by eliminating the potential for linear crack development. With the cutting forces being dispersed radially by the new binder formula, BC8220 excels when machining extremely hard steels. Additionally, the new substrate enables a wider range of applications, provides greater chipping resistance and wears less. The latest technology has also been applied to a specially developed, multi-layer ceramic PVD coating that the BC8220 grade utilises. This all new multi-layer coating includes a TiAlN bottom layer that greatly improves adhesion between the base layer and the CBN surface and provides exceptional peeling resistance. Above this layer is an additional TiAlN ceramic layer that provides excellent chipping and crater wear resistance. Together with a gold coloured, TiN top layer for easy identification of used edges, BC8220 achieves high performance and reliability over a wide range of hardened steel machining applications. A brand new edge honing, named VA, has been included in the choice of BC8220 inserts. It is an ideal all-round honing for light to medium machining and complements the existing GA, GH, TA and TH types. Two chipbreakers, BF and BM complete the series. The BM type is designed for easy and effective removal of carburised layers at depths of cut up to 0.8mm. The BF type is now available as a standard item and can be combined with a wiper geometry for producing first class surface finishes. The initial launch of BC8220 will include an extensive range of negative geometries with multiple cutting edges in CNGA, CNGM, DNGA, DNGM, SNGA, TNGA, VNGA and WNGA types, plus positive CCGT, CCGW DCGT DCGW TPGB CPGB VBGW VCGW geometries.

Scraping bearings and chamfering edges and housing bores is an important task in building an engine. I have several shapes and sizes of lathe tooling cutters that I use by hand. They are precision ground on all four sides for accuracy and a sharp edge. I find that they work better than bearing scrapers for some tasks.

I constructed what I call my tear down cart over 30 years ago. It’s 3′ x 5′ with a bend down the middle and a 1″ drop to one side with a drain. I used a plastic 5-gal pail with a Little Giant parts washer pump. The hose comes up through a standoff pipe opposite of the drain. I disassemble heads, strip blocks and if they’re really nasty and dirty I’ll give them a quick scrub to keep the spray washer cleaner longer. It’s great for rinsing off honing oil from rods and pistons.

Many times, the flange diameter of the rod nuts will contact the radius around the nut seat on some rods. Some jobs may not warrant the expense of spot facing the nut seat on the connecting rods. In that case, it can be quicker and more effective to just machine a chamfer on the ARP rod nuts.

First, too prevent stripping the socket head on tiny screws holding inserts to the tool, or worse, damaging the tool’s threads, apply a small amount of anti-seize or moly grease on the screw threads. Second, to prevent over-tightening, use the proper, small “winged” wrench to tighten the screw.
