Brake Lathe 4000SP Combination Disc and Drum – Ammco

The AMMCO® 4000SP Combination Disc and Drum Brake Lathe offers such legendary reliability and proven performance with one-pass finishing that we’re surprised it even requires an operator. It’s more efficient than ever because it integrates single-speed spindle and feed rates for one pass precision finishes. Technicians can turn standard work quicker and easier. The 4000-SP uses positive rake toolbits for quality cuts you can see, time after time. The result of this simplification is one of the most accurate, durable, and easy-to-use machines you could ever put into your shop.

Product Details

One-Pass Finishing

The AMMCO® 4000-SP is designed for speed. It cuts rotors in one pass, with a high-quality finish. Positive rake tool bits allow for precision turning that produces superior machined surfaces every time. Set it and forget it.

Easy, Efficient Operation

Work quickly and efficiently. Ergonomics are designed for minimal operator movement. Twin cutter dials and depth of cut are clearly marked, and even new operators can quickly turn rotors like seasoned professionals.

Superb Accuracy For Customer Satisfaction

Like every AMMCO® brake lathe, the 4000-SP is a precision tool that cuts to one-thousandths of an inch tolerances. With today’s more sensitive vehicles, this helps ensure customers get smooth braking and complete satisfaction.
Industry Leader in Durability

Many AMMCO® 4000’s are still in service after 40 years of continuous use. Massive “floating spindles” offer superior weight support, and a unique patented system provides a constant oil feed to bearings. It’s designed to work like brand new—for a long, long time.
