JK905
PVC Flush Joint Threading Machine

The JK905 has the capability to thread PVC pipe sizes of 1/2" up to 8" (8.625")

This machine is equipped with a 9" ID hollow spindle which is rotated by a 1hp gear motor powered by an AC frequency drive. The new design incorporates touch screen programming for all dimensions and movements. The automated movements are performed by hybrid closed loop stepper actuators and is controlled by a sophisticated PLC which has the capability to store 10 different thread dimensions and specifications (5 pin and 5 box). The thread cutting motor is a 3 hp 3500 rpm powered by an AC frequency drive. An additional 2 hp motor is used for cutting the part off and oring groove when needed. The JK905 PVC flush joint threading machine has been designed with the latest state of the art micro processing components. The machine’s ease of setup and supreme accuracy will truly amaze you.

The touch screen programming gives you the ability to easily change thread dimensions.  Each step of setting up the thread values is described on their own screen. Once you have entered the appropriate dimensions for each step, the information will be stored and will not have to be entered every time. 

Machine can be setup with 6 different thread pitches. The thread ratios are easily entered through touch screen. No gears, chains or lead screws to adjust. It is all electronically linked from spindle to actuator. Some thread ratios are 2 TPI, 4 TPI, 8 TPI, 3 TPI, 11 1/2 NPT, 8 round taper, 6mm DIN, or 12mm DIN and more. Changing between pipe sizes is much simpler on this machine. First change pipe holding collets and thread cutter if going from ID to OD. From there you will press "Thread Selection" and select the appropriate TPI and thread recipe.

This machine has proven to be extremely dependable and trouble free.  This system can be compared to a scaled down version of a CNC lathe but with more simplicity and ease of operation.  The long term dependability is a result of converting to an electrical system instead of air.  This design simplifies the machine by considerably reducing the number of parts required to operate.

Approximate Thread Times:
4" pipe 2 tpi, .042" step, pin or box thread: 2-3 minutes
2" pipe 2 tpi, .042" step, pin or box thread: 1 1/2-2 minutes
