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 66 to determine the available spindle speed range that includes your calculated spindle speed.

SPINDLE SPEED RANGES

RPM

Low Speed Range 1

18–55

Medium Speed Range 2

55–180

Medium-High Speed Range 3

180–600

High Speed Range 4

600–1800

3.Move 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 rock the chuck by hand to get the gears to mesh.

4.Turn the spindle speed dial shown in Figure 67 all the way counterclockwise to set it to the minimum speed.

Always make sure the variable speed dial is turned all the way down (counterclockwise) before starting spindle rotation. This will help the operator remain in better control if spindle rotation must be stopped immediately after start-up for emergency reasons.

Operating the lathe at spindle speeds higher than 350 RPM could result in gearbox damage when the high (H) gearbox range is selected. Always use spindle speeds of 350 RPM or lower when using a high gearbox range.

5.Turn the spindle ON, and slowly turn the spindle speed dial to your calculated spindle speed.

Power Feed

Both the carriage and cross slide have power feed capability when the carriage is engaged with the feed rod. The rate that these components move (feed rate) is controlled by the headstock and quick-change gearbox lever positions, and the end gear configuration.

Feed rate and spindle speed must be considered together. Keep in mind that the feed rate is expressed in the amount of travel per revolution of the spindle. 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 alternatively be driven by the leadscrew for threading operations. However, this section only covers the use of 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 Threading on Page 59.

SB1042PF specifications

The Southbend SB1042PF is a high-performance commercial range designed specifically for culinary professionals who demand reliability, efficiency, and versatility in their kitchen equipment. This powerful range is engineered to provide outstanding cooking performance while featuring the robust build quality necessary for demanding food service environments.

One of the main features of the SB1042PF is its dual-fuel capability, combining the efficiency of gas burners with the precision of electric ovens. This hybrid approach allows chefs to enjoy the benefits of both cooking methods, such as rapid heating and responsive temperature control. The range typically comes equipped with four heavy-duty cast iron burners, each delivering 30,000 BTUs of cooking power. This ensures that specific dishes can be prepared quickly and efficiently, making this range suitable for high-volume kitchen operations.

In addition to the powerful burners, the SB1042PF features a convection oven that ensures even heat distribution. With a capacity of 26 inches, this oven is perfect for baking, roasting, and delivering consistent cooking results. The oven also includes a two-speed fan that enhances airflow, ensuring that dishes cook uniformly throughout.

The construction of the Southbend SB1042PF reflects its intention for heavy use. The stainless steel exterior not only adds a sleek look to any kitchen but also makes cleaning and maintenance a breeze. The durable cast iron burners are built for longevity, providing chefs with peace of mind even under intense kitchen conditions.

Innovative safety features are also incorporated into the SB1042PF. This range includes flame failure protection, which automatically shuts off the gas supply in case of an extinguished flame, ensuring that kitchens remain safe environments. Additionally, the oven has a temperature control system designed to allow precise adjustments, ensuring that cooking temperatures can match the chef's specifications.

Finally, the Southbend SB1042PF is designed with user comfort and convenience in mind. It features ergonomic controls, easy-to-read indicator lights, and a removable crumb tray for hassle-free cleaning. The range stands as a testament to Southbend's commitment to quality, performance, and innovation, making it an essential piece of equipment for any serious kitchen.
