A dvances in C utting , S awing & S awblades

A NEW range of tungsten carbide tipped bandsaw blades, designed for cutting large cross-sections of metals that are difficult to machine, has been introduced to the UK and the Republic of Ireland by US manufacturer Lenox. It claims the Tri-Tech CT products are versatile in their ability to saw accurately a wide range of materials from high strength steels to nickel-based alloys and says the blade’s robust construction results in longe- vity, high productivity and low cost per cut. Tri-Tech CT has a proprietary set-style tooth pattern, and the positive rake provides strength and durability at the cutting edge. With each pass, the tooth design creates three chips that are claimed to be 50% thicker than most other bandsaws. The sawing action produces straight cuts and eliminates the pinching and seizing that can occur when sawing high stress and work-hardening metals like inconel and other super alloys. High grade carbide tips are precision ground for efficient bandsawing and to balance the work load across all of the teeth in the cut. The backing steel of the Lenox band goes through a detailed preparation process that minimises body breakage and extends the life of the blade. Carbide bandsaw blades for cutting tough metals

Tri-Tech CT blades are available in fourteen specifications ranging from 34mm to 80mm in width and from 1.07mm to 1.6mm thick. There are five teeth per inch configurations: 0.6/0.8, 0.9/1.1, 1.4/1.8, 1.8/2.0, and 2.5/3.4. Two of these are new, making it possible to cut high stress metals in an even wider range of sizes. Materials processed include high-nickel superalloys such as inconel, nimonic, Hastalloy and Waspalloy, iron-based superalloys, tool and mould steels, stainless steels, high chrome alloys, titanium, non- ferrous alloys such as bronze, copper and brass and aluminium. Lenox has also introduced a series of bi-metal bandsaw blades, which it claims last up to 60% longer than other products when cutting solid aluminium and alloyed steels. Marketed under the designation QXP, they are available in the UK and Ireland through the existing Lenox network of distributors.

TheQprefix signifies the proprietarymethod of manufacture, developed by Lenox, that improves the blade’s performance and extends its life. Tooling costs are lower and productivity is increased, as the blade needs to be replaced less frequently. The QXP series is suitable for use on solid stock of mild to moderate machinability, such as aluminium, carbon steel and alloyed steels including stainless and bearing steels. The deep gullet improves chip-carrying capacity, enhancing the blade’s ability to cut at increased speed and feed rates, while the extreme positive rake tooth form penetrates material with less feed force. QXP blades are supplied in sizes from 27mm to 54mm wide and 0.9mm to 1.6mm thick. TPI can be 2/3, 3/4, 4/6 or 5/8.
