Thread Rolling Systems

Axial Rolling
The fastest method of producing accurate threads with superb finish especially on difficult to cut material. Ideal for use on CNC and conventional lathes.

Tangential Rolling
Fast thread rolling from the cross slide.  Ideal for rolling short threads close to the shoulder on multi spindle and CNC lathes.
 
 
Radial Thread Rolling
Extremely fast rolling of short threads with both stationary and rotating heads. Typical rolling times of under 0.3 seconds!
 
 
Replacement Thread Rolls
The widest range of high quality thread and knurling  dies to suit many popular makes of rolling attachments.  Our manufacturing program includes axial, tangential and radial rolls in both standard and special variations.

The following shank options available upon request: plain ground, keyway, cross drill & reamed, 30/40 ISO taper, morse taper, tension/compression.
 
 Unique circular chasers outlast plain blade style chasers. External mounting gives excellent coolant flow and chip evacuation. 

Tangential Rolling
 
Our RT Tangential system is interchangeable with the Fette style tangential thread rolling system. They will fit into your existing machine tool holders and take the same rolls you are currently using:
 
RT10 Diehead = T12 Diehead
 
RT20 Diehead = T18 Diehead
 
RT30 Diehead = T27 Diehead
 
By using lathe type machine tools with automatic, power infeed as with controlled or hydraulic automatics, hydraulically operated copy lathe, NC/CNC lathes, etc., it is now possible to feed from the side of the part and  obtain all of the advantages of the rolling method. RSVP tangential type rolling attachments are especially suited to produce the following threads and profiles:
 
Thread rolled behind a shoulder
 
Extremely short thread lengths
 
Threads with a very short runout 
 (approx. 1/2 - 1 x pitch)
 
Tapered threads
 
Straight knurls DIN 82
 
Burnishing
 
Forming
 
The component must rotate for this application.
 
RSVP tangential side rolling attachments are available in 3 sizes covering a wide range of diameters. It is recommended that the largest rolling attachment that can be adapted on the machine always be used, thereby offering the advantage that the entire work range of the machine can be utilized. Longer threads, maximum component shoulder diameters, and a higher efficiency of the rolling attachment will be attained that way.

Radial Rolling

RSVP Radial rolling heads offer an ideal solution for producing very short threads with tight runout, rolling close to a shoulder or into an undercut. Due to the 3-roll action of the radial system, the component is well supported during the rolling process, even when threading the ends of long shafts. Since the rolling action is completed within one revolution of the rolls, cycle times are extremely short and in most cases, under 0.5 seconds.

Radial rolling heads are automatically reset after each threading pass, but are normally actuated by external means when positioned over the component to be rolled. This is by means of the external trip lever on stationary heads, or an internal push rod on rotating heads.
