Machine Tool Guideway Section Steel

Tianchen cold-drawn machine tool guideway section steel is precision-engineered to meet the stringent demands of high-precision machining applications.Through controlled heat treatment, shot blasting and cold drawing with tungsten carbide dies, our guideway profiles deliver exceptional straightness, tight dimensional tolerances and a smooth, wear-resistant surface. Offered in standard and custom profiles with materials including 45#, 40Cr and GCr15, our guideway bars are widely used in CNC machines, lathes, milling machines and precision automation equipment.Excellent surface hardness reduces friction, prolongs service life and significantly cuts maintenance costs. Supporting flexible orders starting from 2 tons and with reliable global export capacity, Tianchen is your trusted partner for high-quality guideway section steel worldwide.
