Carriage Handwheel

The carriage handwheel moves the carriage left or right along the bed. It has a graduated dial with 0.01" increments, and one full revolution moves the carriage 0.80". Pull the handwheel out to disengage it during power feed operations— this will prevent entanglement hazards.

Cross Slide Handwheel

The cross slide handwheel moves the tool toward and away from the work. Adjust the position of the graduated scale by holding the handwheel with one hand and turning the dial with the other. The cross slide handwheel has a direct-read graduated dial, which shows the total amount of material removed from the diameter of the workpiece (i.e., half the amount of tool movement). The dial has 0.001" (0.02mm) increments, and one full revolution moves the slide 0.100" (5.08mm). Rotate the dial collar 180° to read in metric units.

Compound Rest Handwheel

The compound rest handwheel moves the cutting tool linearly along the set angle of the compound rest. The compound rest angle is set by hand- rotating it and securing in place with two hex nuts. The compound rest has an indirect-read graduated dial with 0.001" (0.02mm) increments. One full revolution of the handwheel moves the slide 0.100" (2.54mm). Rotate the dial collar 180° to read in metric units.

Spindle Speed

Using the correct spindle speed is important for safe and satisfactory results, as well as maximizing tool life.

To set the spindle speed for your operation, you will need to: 1) Determine the best spindle speed for the cutting task, and 2) configure the lathe controls to produce the required spindle speed.

Determining Spindle Speed

Many variables affect the optimum spindle speed to use for any given operation, but the two most important are the recommended cutting speed for the workpiece material and the diameter of the workpiece, as noted in the formula shown in

Figure 65.

Cutting Speed (FPM) x 12

Dia. of Cut (in inches) x 3.14

*Double if using carbide cutting tool

Figure 65. Spindle speed formula for lathes.

Cutting speed, typically defined in feet per minute (FPM), is the speed at which the edge of a tool moves across the material surface.

A recommended cutting speed is an ideal speed for cutting a type of material in order to produce the desired finish and optimize tool life.

The books Machinery’s Handbook or Machine Shop Practice, and some internet sites, provide excellent recommendations for which cutting speeds to use when calculating the spindle speed. These sources also provide a wealth of additional information about the variables that affect cutting speed and they are a good educational resource.

Also, there are a large number of easy-to-use spindle speed calculators that can be found on the internet. These sources will help you take into account the applicable variables in order to determine the best spindle speed for the operation.

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.
