Test Run

 

Floor Mounting

 

 

 

 

 

 

Once assembly is complete, you are ready to test run the drill press.

Wear safety glasses whenever starting or using machine. Failure to comply may result in serious personal injury.

Keep loose clothing rolled up and out of the way of machinery and keep hair pulled back.

To test run the drill press:

1.Turn the power supply ON at the main panel.

2.With your finger poised on the paddle switch (in case there is a problem), flip the START button ON. The drill press should run smoothly, with little or no vibration or rubbing noises.

Investigate and correct for strange or unusual noises before operating the machine further.

If you cannot easily locate the source of a potential problem, refer to Troubleshooting on Page 35. If you still can't solve the problem, contact our Technical Support at (570) 546-9663.

Once you have confirmed that your machine is running properly, we strongly recommend mounting it to the floor to ensure optimum stability.

Lag shield anchors with lag bolts and anchor studs (Figure 22) 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.

Mobile Base

Mounting

Because the drill press is top-heavy by nature, we recommend mounting it to the floor, rather than a mobile base.

If you must use a mobile base, ALWAYS mount your drill press to a base plate inside of the mobile base, as shown in Figure 24.

A good quality base plate increases the standard footprint of the drill press to make it much more stable. The base plate must be at least 11⁄2" thick and made of plywood (do not use OSB, MDF, or particle board) to hold the weight of the drill press. A common way for making the baseplate is described in this sub-section.

Always use extreme care when moving the drill press around with the mobile base!

G7947, G7948 specifications

The Grizzly G7948 and G7947 are powerful, professional-grade milling machines designed for precision metalworking. These models cater to the needs of machinists and hobbyists alike, combining innovation with robust features ideal for various milling tasks.

The Grizzly G7948 is a vertical mill with a large working table, allowing users to handle bigger workpieces efficiently. It features a 2 HP motor, providing a spindle speed range from 50 to 3,000 RPM, enabling operators to tackle a wide range of materials and applications. The G7948’s dovetail column ensures stability and rigidity, minimizing vibrations during operation, which is crucial for achieving precision in milling tasks.

On the other hand, the Grizzly G7947 is a versatile combination of a lathe and a mill, perfect for those looking to maximize functionality in a smaller workspace. It also boasts a robust 1 HP motor, allowing for smooth operation with adjustable spindle speeds, enhancing its versatility. The G7947 is particularly user-friendly, featuring a quick-change tool post that facilitates faster tool swapping and changeovers, which is a significant advantage when working on multiple projects.

Both models come equipped with advanced features such as a digital readout (DRO) system that aids in precision measurements. The DRO provides real-time feedback on the machine's positioning, helping eliminate guesswork and ensuring accuracy. Additionally, the machines' power feed for the table enhances efficiency, making it easier for users to execute repetitive tasks without the strain of manual cranking.

Another notable characteristic of the Grizzly G7948 and G7947 is their user-friendly controls, designed with ergonomics in mind. The intuitive layout ensures that operators can easily navigate through the machine’s settings, allowing for quicker setup times and smoother workflow.

Lastly, the sturdy construction of both milling machines means they are built to withstand rigorous use, making them reliable choices for both industrial applications and serious hobbyists. These models exemplify Grizzly's commitment to quality and performance, making them exceptional additions to any workshop.
