While standard linear shafts are supplied as plain rods, most practical applications require customized end machining to integrate the shaft into a machine frame. Because this machining is performed on shafts that are already case-hardened, it requires specialized equipment and processes .
Common Machining Configurations:
Radial Drilling & Tapping:
Description: Holes drilled and tapped radially along the length of the shaft.
Function: Primarily used to mount the shaft onto a continuous support rail (SR or TBR series), eliminating deflection over long travel distances.
Stepped Ends:
Description: Precision turning to reduce the shaft diameter at the extremities.
Function: Allows the shaft ends to fit into specific support blocks or bearings that are smaller than the main travel shaft diameter.
Threaded Ends (Male/Female):
Description: Internal (female) or external (male) threads machined onto the shaft tips.
Function: Enables the shaft to be rigidly secured to a wall or mounting plate using bolts or locking nuts.
Keyways & Flats:
Description: Milling a flat surface or slot onto the shaft end.
Function: Provides a mechanical lock to prevent the shaft from rotating, which is critical for single-rail system configurations.
