TMG21.90 Indexable and fine-tuning boring cutters module for small diameter holes
 
The indexable and fine-tuning cutters module for small diameter holes is applicable to precessing high precision and roughness small holes parts with size range 3-32 mm in diameter by machine center, NC machine tools, and all kinds of boring and milling machine tools in the heavy machine tools industry, machine tools, textile, auto parts production and other industries. The boring cutters module should be used together with TMG21 tools module. This boring cutters module has built in cooling channel and cooling liquid can be directly rushed to the cutter blades through the inside cooling channel. The fine-turning scale resolution in diameter size is 0.02 mm, the fine-turning accuracy error in diameter size is 0.005 mm, with good rigidity and repeated adjust accuracy. For processing length-diameter ratio for 5-8 deep holes, boring tools rod is made of the special high gravity alloy materials to increase vibration resistance. The boring cutters module consists of cutter support, five boring tool rods and spanner, boring tool rods could change fast and convenient, reliable and high accuracy for adjust size.
