EVS Toolroom Lathes

Manual Feed

You can manually move the cutting tool around the lathe for facing or turning operations using the handwheels shown in Figure 77 and described below.

Carriage Handwheel

The carriage handwheel moves the carriage left or right along the bed. Use this control when setting up the machine for facing or turning.

Cross Slide Handwheel

The cross slide handwheel moves the tool toward and away from the work. Turning the dial clockwise moves the slide toward the workpiece. Adjust the graduated scale by holding the handwheel with one hand and turning the dial with the other. The graduated scale reads in 0.001" increments and is a "direct-read" which means that the distace on the collar reflects the amount removed from the diamter of the workpiece.

Compound Slide Handwheel

The compound slide handwheel controls the position of the cutting tool relative to the workpiece. The compound is adjustable for any angle within its range. Angle adjustment is secured by two nuts on the base of the compound. The graduated scale reads in 0.001" increments and is a "indirect-read" which means that the distace on the collar reflects the distance that the tool moves.

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 operations, 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 78:

*Recommended

Cutting Speed (FPM) x 12

= SpindleSpeed (RPM)

Dia. of Cut (in inches) x 3.14

*Double if using carbide cutting tool

Figure 78. 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. All of these sources will help you take into account all the applicable variables in order to determine the best spindle speed for the operation.

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.
