-Installed an isolated cooling fan in the interior of motor to dissipate heat. Make the machine can be operated continuously,steady and durable.
-The vertical column is enlarged (60mm),vertical column is solid and treated by tempering to get rid of stress, surface is chrome plated, wear resisting and no rust.
-High speed rotation continuously which can rotate 50 times/per Minute.
-Free to exchange tiny pitch.
-Quick and easy to change gear pitch and collet.
-Gear drives by one side teeth so won't have gap there.
-The rotation of gear is slow, so the gear won't get wear.
-Because one rotate one pitch, it can process perfect thread and prolong the TAPs life.
-The workpiece won't be lifted while the spindle retracting, so don't need to keep pressure on the workpiece, only need to avoid anti-rotation when tapping. This can simplify the fixture and make cost down.
