Description
This Cross Feed Screw is manufactured from hardened, high-strength alloy steel for long service life and stable performance. The screw features precision-cut threads for accurate linear displacement and smooth saddle travel. The design includes a machined end for connecting to a handwheel, dial, or power feed unit.
It is commonly used as a replacement part in Bridgeport-type milling machines, M1TR mills, and other vertical milling machines requiring Y-axis feed repair or maintenance.
Applications:
- Vertical turret milling machines
- Bridgeport-type milling machines
- M1TR (RAM-type) milling machines
- Machine restoration, service, and maintenance
- Replacement for worn or damaged Y-axis feed screws
Advantages:
- Improves machining accuracy
- Reduces saddle vibration and wear
- Ensures smooth table travel
- Increases machine reliability and lifespan
- Direct replacement part for many mills
Compatibility:
- Bridgeport Series 1 Type Mills
- M1TR Milling Machines
- Vertical Turret Mills (Asian Bridgeport-style)
- 4S / 3S Milling Machines
- Custom retrofitted milling tables
More questions buyers ask
What is a Y-axis cross feed lead screw?
It is a precision-threaded rod that converts rotational motion from the handwheel into linear movement for the Y-axis (cross-slide) of a milling machine.
Which machines are compatible with this lead screw?
This lead screw is designed for Bridgeport-type vertical turret milling machines, specifically M3 and M4 models.
What material is the lead screw made of?
It is constructed from high-strength, hardened alloy steel for superior durability and wear resistance.
Does the lead screw come with a nut?
Yes, each unit includes a matching brass feed nut to ensure low-backlash operation.
What is the thread type?
It features a precision ACME thread, which is the industry standard for power transmission in machine tools.
How do I maintain the lead screw?
Regular cleaning and lubrication with high-quality machine oil or grease are essential to maintain accuracy and prevent premature wear.
Can this be used for CNC retrofitting?
Yes, many users utilize these high-quality lead screws for manual-to-CNC conversion projects on Bridgeport-style mills.
What is the typical backlash?
When paired with a new matching nut, the backlash is typically ≤ 0.10–0.15 mm.
Is the lead screw hardened?
Yes, the screw is hardened and ground to ensure smooth, accurate movement and a long service life.
Do you provide GST invoices?
Yes, all purchases include a valid GST invoice for business accounting purposes.
Who should choose the M3-compatible lead screw?
Choose this if you own a standard M3 turret milling machine with a 1270x254 mm table and require a direct, high-quality replacement for the Y-axis.
Who should choose the M4-compatible lead screw?
Choose this if you operate an M4 turret milling machine with a larger 1370x254 mm table and need a specific fit for the Y-axis cross feed.
How does the Y-axis screw differ from the X-axis screw?
The Y-axis screw is shorter and designed for cross-slide movement, whereas the X-axis screw is significantly longer to accommodate longitudinal table travel.
Why choose Pentagon over generic replacements?
Pentagon lead screws are manufactured with precision-ground ACME threads and high-strength alloy steel, offering better accuracy and longevity than generic alternatives.
