Product Introduction
Machine Tool Guide is a nano-polymer composites based on PTFE material,applying in all types of predision machine tools requiring high accuracy,CNC equipments and high-end guide bands products of processing centers. The guide bands contain rich solid lubricant particles,which enables the bands have a excellent friction and wearing properties. By force of nano super fine recipe,uniform and dense material and strong wearing resistance,the soft bands are widely used in all types of common machine tools,textiles,printing,paper-manufacturing,food,chemical engineering,woodworker or manufacture and maintenance of other mechanical sliding guide.,especially precision machine tools etc.
Property Characteristics
1)High Wearing Resistance: normally ten times of cast iron guide,good accuracy maintenance
2)Low Friction: friction coefficient<0.04,only 1/3 of cast iron guide,reducing the driving-energy consumption
3)No Creeping: moving steadily
4)Good Shock-absorbing Ability: improving processing accuracy
5)Good Lubrication
6)Easy-to-do Maintenance: as the hardness is much lower than metal,friction is mainly on the bands,we can just replace new bands. Meanwhile,it prevents the middle-deboss of the machine tool body.
