Pentagon Milling Machine Lead Screw Price in India — Cross Feed Y-Axis Lead Screw-Turret mill M3-0027

A lead screw is a crucial component that translates rotational motion from a handwheel or motor into precise linear motion of the machine's table (X and Y axes) or knee (Z axis).

These lead screws are manufactured from high-grade, hardened alloy steel for maximum durability, precision, and a long service life.

TPI stands for Threads Per Inch. A 5 TPI pitch means there are 5 threads for every inch of the screw's length, which determines the travel distance for each rotation.

Each lead screw comes as a set with a matching brass nut to ensure smooth operation and minimize backlash.

Backlash is the small amount of play or lost motion between the screw and the nut. A new screw and nut set reduces backlash to a minimum (≤ 0.10–0.15 mm), which is critical for machining accuracy.

While designed for PENTAGON M3 and M4 models, they may be compatible with other Bridgeport-type turret mills. Please check the dimensions (total length, diameter) carefully before ordering.

Signs of a worn lead screw include difficulty in moving the table, excessive backlash (sloppy handwheel feel), and inaccuracies in your machined parts.

The Y-axis (cross-feed) lead screw moves the milling machine's saddle towards and away from the operator, controlling the 'in-and-out' position of the workpiece.

The X-axis (longitudinal) lead screw moves the milling machine's table left and right, controlling the primary cutting feed.

The Z-axis lead screw moves the machine's knee up and down, controlling the depth of cut.

This screw is specifically for owners of the PENTAGON M3 Turret Milling Machine (or compatible models with a 1270x254 mm table) who need to replace a worn or damaged Y-axis (cross-feed) screw.

This vertical feed screw is designed for the knee (Z-axis) of both PENTAGON M3 and M4 models. Choose this part if you need to restore precise vertical movement to your machine.

This is the longitudinal feed screw for the PENTAGON M3 Turret Mill. It is the correct choice for replacing the main left-right table movement screw on the M3 model.

This screw is specifically for the larger PENTAGON M4 Turret Milling Machine (1370x254 mm table). It is designed to handle the Y-axis (cross-feed) movement for this model.

This is the longitudinal feed screw for the PENTAGON M4 Turret Mill. As the longest screw, it is essential for replacing the main left-right table movement screw on the larger M4 model.

The primary difference is length. The X-Axis screw for the M4 (1530mm) is longer than the one for the M3 to accommodate the M4's larger table size. Always choose the screw that matches your machine model.

No, while they share the same model number (D-0027), they are distinct parts. You must select the variant specific to your M3 or M4 machine for correct fitment.

The X-axis (longitudinal) lead screws are the longest, with the version for the M4 model being the longest overall to support its larger table.
