Three-jaw Solid Pneumatic Chuck

Features:

This product is a national patented product with independent intellectual property.

Connecting way of this chuck and spindle is in accordance with relative national standards. Without of changing tool structure, the user only needs to install piston flange with corresponding size of chuck.

With chuck body itself as cylindrical and internally-installed piston, the chuck carries out clamping and loosing actions by controlling devices in spindle end.

Chuck with solid chuck has the advantage of strong clamping force.

This product is suitable for processing for gear, disc type work pieces and short axis etc.

Installation process of a Pneumatic Chuck:

open wooden box, take out the
connecting sleeve and connect it
to the spindle tail by pinching screws. Open wooden box, take out the
connecting sleeve and connect it
to the spindle tail by pinching screws. Use the dial indicator to rectify the
outer Cylindrical of connecting sleeve,
and the tolerance must be less than 0.05mm

Use the dial indicator to rectify the
outer Cylindrical of connecting sleeve, and the tolerance must be less than 0.05mm. Open wooden box; take out thechuck, and put it on the table, Check whether the accessories is complete.Prepare the vice, scissors, dial indicator, adhesive tape, clean cloth rags, caliper, wire (1-meter), one electric drill, one hammer. Use caliper to measure the chuck’s back stage height and diameter, checking whether the chuck can match the flange on the lathe. If not match, according to chuck size, adjust and finish the flange.

With a clean cloth to wipe clean the back of chuck. With a clean cloth to wipe clean the lathe and flange. Take out the trachea, and take out two hoops from the annextransparent bag, then set them on trachea top

Use scissor to expand trachea interface (should not be too large, so as not too loose when insert) or put it in boiling water making it easy to install. Install the trachea in the trachea tip, marking 1 and 2 trachea, as a mark
Note: After installing trachea, straighten it up; check the trachea and trachea mouth is smooth. Tracheal here can not be distorted, or else after installing the spindle it will be of poor ventilation, and the chuck will not work neither. Use the vice to clamp the hoops, in order to prevent the loss of the trachea. (Take care not to break the folder of trachea)

Bind up the trachea with adhesive tape, and prevent distortion of tracheal. Pull the trachea smoothly, then inspect whether it bend or not. Use Wire to thrill through the trachea `s other side, through the spindle lathes, gently pull the trachea, and move the chuck synchronous backward, then buckle the chuck on the flange plate.

Cut off redundant trachea on spindle tail; we must again distinguish between NO.1 and NO.2 trachea.	Remain about 100mm at the spindle external, and it can spring back to the spindle.	Using air gun, blow into the NO.1 trachea, to see whether the chuck is clamp; blow into NO.2 trachea, to see whether the chuck is release, so as to determine whether the trachea in spindle is distorted.

Connecting air derivative cricoid sleeve, NO.1 and NO.2 trachea will be connected to the trachea mouth 1 and 2 respectively, before insert; the hoop must be put on the trachea.	Using air gun, blow into the NO.1 and NO.2 air derivativecricoid sleeve, to see whether the chuck is clamp or release,so as to determine whether the tracheas in derivativecricoid sleeve is distorted	L-tighten the nut, fix the air derivative cricoid sleeve


Tighten the screw under the air derivative cricoid sleeve, to prevent it rotate with the lathe	Connect the trachea in order, fix the LJW on lathe.	Connect the trachea in order, fix the LJW on lathe.	Open the oil reservoir; add clean oil to 80%. Note: When Open, take care not to damage or fall the O-ring on top surface.


Upward and turn right and left the pressure gauge to 0.60 Mpa, at this time, the trachea in a intake state. After adjusting, reset the knob down.	Turn right and left the oil reservoir, + is to enlarge the volume, - is to reduce the volume. Push the switch, if we can see the oil upward to drop out, it is ok. In general, the arrow on the knob adjustment points to the figures 3-4.	Installed pneumatic chuck and trachea’s bending state in spindle.
