SECTION 6: MAINTENANCE

To reduce risk of shock or accidental startup, always disconnect machine from power before adjustments, maintenance, or service.

Schedule

For optimum performance from your machine, follow this maintenance schedule and refer to any specific instructions given in this section.

Ongoing

To maintain a low risk of injury and proper machine operation, if you ever observe any of the items below shut the machine down immediately, disconnect it from power, and fix the problem before continuing operations.

•loose mounting bolts or fasteners.

•Worn, frayed, cracked, or damaged wires.

•Missing belt guards.

•reduction in braking speed or efficiency.

•Any other unsafe condition.

Before Beginning Operations

•Turn the spindle direction switch to the off (middle) position to prevent spindle startup when connected to power (see Page 23).

•Move the spindle speed range selector to the manual (forward) position to prevent the spindle from unexpectedly auto-downfeeding when rotation is started (see Page 38).

•Make sure the X-axis power feed is turned OFF to prevent unintentional table movement when connected to power (see Page 28).

•perform lubrications tasks as directed in the Lubrication section on Page 44.

•Check table movement in all three axes directions for loose/tight gibs. Adjust the gibs if necessary (see Page 51).

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

Daily, After Operations

•Disconnect the machine from power.

•Vacuum/clean all chips and swarf from table, slides, and base.

•Wipe down all unpainted or machined sur- faces with a good quality rust preventative.

Cleaning &

Protecting

Regular cleaning is one of the most important steps in taking good care of this mill. Each opera- tor is responsible for cleaning the machine imme- diately after using it or at the end of the day. We recommend that the cleaning routine be planned into the workflow schedule, so that adequate time is set aside to do the job right.

Typically, the easiest way to clean swarf from the ways and table is to use a wet/dry shop vacuum that is dedicated for this purpose only. The small chips leftover after vacuuming can be wiped up with a slightly oiled rag. Avoid using compressed air to blow off chips, as this may drive them deep- er into moving surfaces and could cause sharp chips to fly into your face or hands.

Besides the ways and elevation leadscrew, all other unpainted and machined surfaces should be wiped down daily to keep them rust-free and in top condition. This includes any surface that could be vulnerable to rust if left unprotected (this espe- cially includes any parts that may be exposed to water soluble cutting fluids). Typically with these parts, a thin film of oil is all that is necessary for protection.

Keep tables rust-free with regular applications of products like G96® Gun Treatment, SLipit®, or Boeshield® T-9 (see Section 5: Accessories on Page 42 for more details).

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.
