MAINLAND CA6140/750 MANUAL LATHES

Technical Description

The MAINLAND CA6140/750 Manual Lathe is a precision-engineered machine designed for versatile metal turning applications. It features a **maximum swing of 15.75 inches (400 mm)** over the bed and a **distance between centers of 29.53 inches (750 mm)**, suitable for machining medium-sized workpieces. The lathe is equipped with a robust spindle having a **bore diameter of 3.15 inches (80 mm)**, enabling the accommodation of sizable shafts and tooling. Its spindle operates at speeds up to **1,400 RPM** with multiple steps, providing flexibility for different cutting operations and materials. The **swing over the cross slide is 8.25 inches (210 mm)**, allowing accurate machining close to the tool post. Powered by a 7.5 kW (10 HP) motor, the CA6140 supports precise turning, threading (metric and inch), drilling, reaming, and grooving on steel, cast iron, and nonferrous metals. The lathe bed is 400 mm wide with hardened rails for long-lasting durability and precision. It accommodates standard 25x25 mm tool post sections and features a manual braking system for operational safety. The tailstock spindle travels up to 150 mm and uses an MT5 taper for tooling attachment, enhancing versatility. The CA6140/750 model balances rigid construction with smooth, high-accuracy machining to achieve fine surface finishes and dimensional tolerances up to IT7, making it suitable for tool rooms, maintenance, and small batch production environments.
