Setting Spindle Speed

1.Make sure the spindle is turned OFF and it has come to a complete stop.

2.Use the chart in Figure 79 to determine the available spindle speed range closest to your calculated spindle speed.

Figure 79. Spindle speed range chart.

If the headstock is in high range (400-2500 RPM), and if the spindle speed dial is turned completely to the left, the tachometer may show a speed lower than the 400 RPM listed on the headstock label. This headstock label indicates the allowable spindle speed for cutting operations within that range. If the lever is in high range, do not attempt cutting operations below 400 RPM.

3.Adjust the spindle speed range lever to the range that covers your calculated spindle speed.

Note: To shift the spindle speed range lever, you may need to apply pressure to the lever and slightly rotate the spindle by hand.

Make sure the variable speed dial is turned all the way to the left (counterclockwise) before turning the lathe ON, or it may start up at a dangerously high rate of speed.

4.Turn the spindle ON and slowly turn the variable speed dial to carefully adjust the spindle speed (shown on the digital display) to your calculated spindle speed.

Power Feed

On this machine, both the carriage and cross slide have power feed capability. The rate that these components move (feed rate) is controlled by how the levers are configured on the gearbox.

Feed rate and spindle speed must be considered together. The sources you use to determine the optimum spindle speed for an operation will also provide the optimal feed rate to use with that spindle speed.

Often, the experienced machinist will use the feeds and speeds given in their reference charts or web calculators as a starting point, then make minor adjustments to the feed rate (and sometimes spindle speed) to achieve the best results.

The carriage can alternately be driven by the leadscrew for threading operations. However, this section covers using the power feed option for the carriage and cross slide components for non-threading operations. To learn how to power the carriage for threading operations, refer to the Threading Controls section Page 48.

SB1012 specifications

The Southbend SB1012 is a versatile and efficient commercial range designed specifically for the rigorous demands of professional kitchens. This powerful cooking appliance features a robust construction and advanced technologies that cater to chefs who require precision and reliability in their culinary endeavors.

One of the standout features of the SB1012 is its powerful burners, which come equipped with heavy-duty cast-iron grates. The range typically includes four open burners that deliver exceptional heat output. This allows chefs to achieve quick boiling, searing, and simmering, thereby ensuring perfect cooking results every time. The burners are designed to provide consistent heat distribution, reducing the chance of hot spots and uneven cooking.

The Southbend SB1012 also incorporates a 12-inch griddle, adding another layer of versatility to its functionality. The griddle is constructed from high-quality materials that provide even heat and withstand high temperatures, making it suitable for cooking everything from pancakes to stir-fried dishes. The grease trough and easy-to-clean design contribute to the overall efficiency of the kitchen.

In addition to its cooking surfaces, the SB1012 features a spacious oven compartment, designed to accommodate larger pans and dishes. With a temperature range that typically goes up to 500 degrees Fahrenheit, the oven is ideal for baking, roasting, and other cooking techniques that require precise temperature control. The inclusion of a built-in temperature gauge helps chefs monitor cooking conditions at a glance.

Durability is a hallmark of the Southbend SB1012. The range is constructed from heavy-duty stainless steel, which not only enhances its aesthetic appeal but also ensures resistance to wear and tear in a busy kitchen environment. The removable ovens and easy-access components facilitate straightforward cleaning and maintenance, ensuring the equipment remains in peak condition even after extensive use.

To further improve user experience, the Southbend SB1012 is designed with safety features in mind. The range often includes pilot lights for easy ignition, and the heavy-duty construction minimizes the risk of accidental damage.

In summary, the Southbend SB1012 combines powerful cooking performance with durable construction and ease of use, making it a preferred choice for professional kitchens looking to optimize their cooking capabilities. Its advanced features, versatility, and reliability are tailored to meet the high standards of culinary professionals.
