Dual Spindle Thread Roller
Dual Spindle Thread Roller
The VA-D, Dual-Spindle thread rollers are designed to roll threads above and below the shoulder.
■ The threads can be either different or similar.
■ The two heads are independent, eliminating influence of one on the other, enabling use of simple and economical rolling dies.
■ Both stations have Controlled Thread Rolling Start, Hydraulic Clamping, Zero-Taper Mechanism for parallel threads and Micrometric Thread Pressure Screws as well as an AC Speed Controller, Automatic Air Shut-Off and two Operator Control Panels.
The VA-K models are designed to roll threads in the first station and roll knurls in the second station
■ Independent adjustments on both stations assure better quality of each thread.
■ Higher production speeds. The second operation does not slow down the machine.
■ Less handling, eliminating possibility of mixing parts.
■ Inexpensive tooling and full control of the quality of each rolling operation. Tools are replaced in minutes.
