ROUND SHANK MICRO-ADJUSTABLE CARTRIDGES

Renuka Tools offers Round Shank Micro-adjustable Cartridges. It has many advantages. The adjustment spindle is rigidly secured at the rear of the cartridge housing between two thrust bearings, eliminating all axial and radial play, and is provided with fine micrometer threads into which the threaded shoulder of the tool is screwed. The tool is supported on adjustable bearing in the front part of the housing with two keys on its shaft, which slide in guide slots and prevent the tool from twisting. It is tightly clamped as closely as possible to the cutting edge with a split collet accessible from the front of the housing. Forward and backward adjustment of the tools is controlled by turning the setting spindle. When the tool is rigidly clamped, this also reduces the force required for adjustment, as the two ball bearings reduce the frictional resistance, making adjustment sensitive and accurate. The amount of adjustment can be read off against marking. Advantages: fast, accurate tool setting simply using setting spindle; maximum accuracy - tool is adjusted when clamped; anti-backlash design; large turning range - in addition to micro adjustment, the whole cartridge can be moved; easy mounting - only requirements close tolerance bore and tapped hole for clamping; minimum weakening of boring bar - due to small dimensions of cartridges; suitable for standard boring bars; and excellent for external turning - on automats, turret lathes and special machines. A range of tool bits and accessories for machine tools are available.
