1. Introduction
(1) Introduction
WARNING
Any modification and change in usage of the machine is highly
prohibited for unexpected damage or hazard may occur.
Since the Saw Head of the machine cuts down smoothly the material
through the guide on the vertical column, the surface of material is very
clean and has almost no burr. This machine is very efficient for the precise
cutting.
The gear box consists of several “Carburizing Heat-Treatment”Helical
Gears, which are very durable. There is almost no noise and no vibration.
High drive-efficiency makes it possible to perform a powerful and fast
cutting.
Specially designed vise structure brings it to perform a powerful clamp
capacity. Knurling process and a high frequency heat treatment of vise
surface help the material to stick to the vise well. The support vises can be
adjustable depending on the length of material and they can move freely
according to operator’s preference.
The Sawing Head can be adjusted from left 45° to right 40° in order to
work the angular cutting.
The chip of cut-material on the saw blade can be rejected by chip ejector.
The cleaning of coolant tank is very easy.
You can keep the tools and blade in the front drawer inside of stand.
