Performance and Structure

The ACE Jobber LM is built for rigidity and performance. Its Linear Motion (LM) guideways bring smooth, low-friction movement, which improves both speed and precision. Compared to traditional box-type guideways, LM guideways offer better dynamic response and reduced wear. This makes the Jobber LM particularly effective when frequent rapid moves or precise positioning are required.

The machine’s spindle is also thermally stabilised, which helps maintain accuracy under varying operating conditions. A stabilized spindle reduces thermal drift, a common issue in high-speed machining, ensuring consistent performance over long production runs. The bi-directional turret (8 stations) allows flexibility and quick tool changes.

Control Options

The Jobber LM supports both Fanuc and Siemens CNC control systems. These widely used systems allow the operator to choose based on preference and compatibility with existing shop infrastructure. The control drives the spindle and axes, enabling smooth acceleration and accurate taper or threading operations.

Features and Accessories

A number of standard and optional features make the Jobber LM a versatile machine tool for a variety of turning applications

• Hydraulic Power ChuckStandard chuck option (Ø200 mm) helps secure parts reliably for consistent machining. contentReference[oaicite18]
• Tailstock with Live CenterUseful for supporting long workpieces during turning to avoid deflection and vibration. contentReference[oaicite19]
• Automatic Central Lubrication SystemEnsures constant lubrication of critical components without frequent manual intervention. contentReference[oaicite20]
• Chip ConveyorRear or side-mounted chip conveyor helps maintain a clean workspace and efficient disposal of turned chips. contentReference[oaicite21]

• Programmable quill for more flexible tailstock operations contentReference[oaicite25]
• Rigid tapping functionality for producing threads with precision contentReference[oaicite26]

Operational Advantages

One of the main benefits of the Jobber LM is its efficiency in job shop production. The combination of a fast 4,000 rpm spindle and rapid axis traverse (30 m/min) reduces cycle time, allowing more parts to be completed in less time. The precision of LM guideways helps maintain quality, even under continuous production.

Another advantage is the machine’s stable design. With a heavy machine base and thermally stabilised spindle, the Jobber LM is built to withstand heat fluctuations and maintain alignment, contributing to consistent part quality over long runs.

The 8-station turret supports a variety of tools, making it flexible for multi-operation tasks such as facing, boring, and external turning. This flexibility reduces the need for multiple machines or setups.

Applications and Industry Use

The ACE Jobber LM is particularly well-suited for industries where medium-volume turned components are required. Typical applications include

• Automotive parts, such as shafts, pins, and threaded components.
• Hydraulic components, including valve bodies and connectors.
• General engineering work requiring precise cylindrical parts.
• Small to medium-scale workshops looking for a reliable CNC lathe for contract jobs.

Economic and Productivity Considerations

For small and medium enterprises, the Jobber LM offers a strong balance between cost and capability. Its design allows for high productivity without compromising on precision, making it a cost-effective capital investment. Also, the availability of both Fanuc and Siemens controls means that shops can use existing programming skills and tooling standards, reducing training and setup costs.

Maintenance and Reliability

Maintenance for the Jobber LM is made easier through its automatic lubrication system and clear access to hydraulic and coolant systems. Regular upkeep of the linear motion guideways ensures long-term performance and precision. The machine’s design aims to minimize downtime, making it reliable for demanding shop environments.

Safety and Ergonomics

Operator safety is addressed through well-thought-out features. The power-operated chuck simplifies loading and unloading, while the machine’s guards and chip conveyor help manage debris. The control panel is positioned for operator convenience, and the machine architecture supports a clean working space.

The ACE Jobber LM specification defines a well-engineered horizontal CNC turning center optimized for precision, speed, and durability. Its LM guideways, high-power spindle, and flexible tooling make it an excellent choice for job shops and small to medium manufacturers. With strong performance, a robust build, and a suite of features designed for production efficiency, the Jobber LM offers a reliable solution for turning tasks across diverse applications. Whether for automotive components, general engineering parts, or daily workshop jobs, this machine provides a balanced combination of accuracy, power, and productivity.
