CLG-500
1) Dresser
The dressing device is made of high-grade cast iron via precision grinding and scarping. the angle of dressing device on the control wheel can be adjusted(±5°) during grinding according to the nature of the workpiece and actual requirements, so as to ensure a good contact surface between the workpiece and control wheel, and to achieve optimal straightness and surface precision.
2) Spindle
The spindle of the grinding wheels and control wheels are made of high quality alloy steel that has under-gone normalization, tempering, high frequency and subzero treatment before the precision grinding, in order to improve product stability, prevent deformation and prolong service life.
3) Bottom slide
Shaped slide rails and double wedge auxiliary guides are used for the bottom slide. the double ^-shaped slide rails have undergone high-frequency hardening treatment and precision grinding, which can block out mud, while offering a lightweight and precise structure.
4) Machine bed
The centerless grinding machine adopts a high-grade cast iron lathe bed, its internal stress is eliminated through appropriate heat treatment to ensure the durability of the machine
