Test Run

After all preparation steps have been completed, the machine and its safety features must be tested to ensure correct operation. If you discover a problem with the operation of the machine or its safety components, do not operate it further until you have resolved the problem.

If you discover a problem with the operation of the machine or its safety components, do not oper- ate it further until you have resolved the problem. Refer to the Troubleshooting section on Page 49 for solutions to common problems that may occur with all mills. If you need additional help, contact our Tech Support at (570) 546-9663.

Mill Test Run

1.Read and follow the safety instructions at the beginning of the manual, take required safety precautions, and make sure the machine is set up and adjusted properly

2.Clear away all tools and objects used during assembly and preparation.

3.Make sure that the mill is properly lubricated (refer to the Lubrication section on Page 44 for specific details).

4.set the spindle speed to the low range (refer to Page 33 or 35 for detailed instructions).

5.Move the downfeed selector to the manual (forward) position so that the spindle does not downfeed during this test (refer to the Downfeed Operations section on Page 36 for detailed instructions).

6.Connect the mill to the power source speci- fied in the POWER SUPPLY section on Page 14.

Model G0747/G0748 (Mfg. Since 8/12)

7.use the spindle switch to turn the mill ON.

For Model G0747: Turn the spindle switch to the FLOW (forward low) position, as shown in Figure 14.

Figure 14. Model G0747 spindle switch.

For Model G0748: Turn the spindle switch to the FOR (forward) position, as shown in Figure 15.

8.listen for abnormal noises and watch for unexpected actions from the mill. The machine should run smoothly and without excessive vibration or rubbing noises.

—strange or unusual noises or actions must be investigated immediately. Turn the machine OFF and disconnect it from the power source before investigating or cor- recting potential problems.

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.
