Leveling & Mounting

Generally, you can either bolt your machine to the floor or mount it on machine mounts. Although not required, we recommend that you secure the machine to the floor and level it while doing so. Because this is an optional step and floor materi- als may vary, hardware for securing the machine to the floor is not included.

Unless otherwise specified by your local codes, this machine MUST be secured to the floor if it is permanently connected (hardwired) to the power supply.

Leveling

Leveling machinery helps precision components, such as dovetail ways, remain straight and flat during the lifespan of the machine. Components on an unleveled machine may slowly twist due to the dynamic loads placed on the machine during operation.

For best results, use a precision level that is at least 12" long and sensitive enough to show a distinct movement when a 0.003" shim (approxi- mately the thickness of one sheet of standard newspaper) is placed under one end of the level.

See Figure 7 for an example of a high precision level available from Grizzly.

Bolting to Concrete Floors

Anchor studs and lag shield anchors with lag screw (Figure 8) are two popular methods for anchoring an object to a concrete floor. We sug- gest you research the many options and methods for mounting your machine and choose the best that fits your specific application

Machine Mounts

Machine mounts (see Figure 9 for an example) provide the advantage of fast leveling and vibra- tion reduction. The large size of the foot pads distributes the weight of the machine to reduce strain on the floor.

G0747 and G0748 specifications

The Grizzly G0747 and G0748 are advanced metal lathes designed for precision machining and versatility, catering to both amateur machinists and professional workshops. These machines stand out in the realm of metalworking equipment, thanks to their robust construction and innovative features.

One of the key attributes of the G0747 and G0748 is their solid cast iron construction, which provides excellent vibration dampening during operation. This enhances stability and precision, crucial for producing high-quality machined parts. Equipped with powerful motors, both models are capable of handling a wide range of materials, from aluminum to harder metals like steel.

The G0747 features a variable speed drive system, allowing users to adjust the spindle speed based on the project at hand. This flexibility is beneficial for tasks that require different cutting speeds, enabling machinists to optimize cutting performance and tool longevity. Its variable speed output ranges, alongside smooth torque delivery, make it ideal for intricate turning operations.

On the other hand, the G0748 includes an advanced digital readout (DRO) system. This feature provides real-time feedback on the machine's position and speed, significantly improving accuracy in measurements during machining tasks. The DRO system allows operators to set precise limits and keep track of their progress, essential for complex projects where exact dimensions are critical.

Both lathes are equipped with a user-friendly interface, making them accessible for beginners while still offering advanced functionalities that seasoned professionals appreciate. They include multiple tooling options, allowing for an expansive range of machining techniques including turning, threading, and drilling.

Moreover, the G0747 and G0748 come with a comprehensive assortment of accessories, such as different types of chucks and tool holders, which further extends their capabilities. The ease of changing tooling and quick setup times are significant advantages for shops aiming for efficiency and versatility in their operations.

In conclusion, the Grizzly G0747 and G0748 metal lathes are exemplary units that balance power, precision, and user-friendliness. Their advanced features, such as variable speed capabilities and digital readouts, equip machinists with the tools necessary to produce exceptional work. Whether for hobbyists or industrial applications, these lathes are built to meet a variety of machining needs with impressive performance and reliability.
