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".

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 72.

*Recommended

Cutting Speed (FPM) x 12

= SpindleSpeed (RPM)

Dia. of Cut (in inches) x 3.14

*Double if using carbide cutting tool

Figure 72. 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 uniform airflow helps to achieve consistent cooking results, reducing the risk of hot spots and unevenly cooked dishes, which is crucial for professional chefs aiming for culinary perfection.

The Turn-X oven is equipped with a user-friendly digital control panel that allows chefs to easily program and monitor cooking times and temperatures. This feature enhances the ease of use, enabling kitchen staff to multi-task efficiently without compromising on the quality of the dishes being prepared. With pre-set cooking options, the oven can accommodate a wide range of recipes, from baking to roasting.

Another notable feature of the SB1053F is its robust construction. Built with high-quality stainless steel, the oven is designed to withstand the rigors of a busy kitchen environment. The durable exterior not only provides an appealing aesthetic but also ensures easy cleaning and maintenance, a vital aspect for maintaining hygiene in food service operations.

The Turn-X also incorporates energy-efficient technologies, providing significant cost savings. Its advanced insulation minimizes heat loss, allowing the oven to reach and maintain optimal cooking temperatures quickly while using less energy. This feature is particularly beneficial for establishments aiming to reduce their environmental footprint while controlling operational costs.

The spacious cooking chamber accommodates multiple racks, maximally utilizing the available space. This design allows for high-volume cooking, ideal for restaurants with heavy demand during peak hours. The oven’s versatility makes it suitable for various cooking styles, including baking pizzas, roasting meats, and even dehydrating fruits or vegetables.

In conclusion, the Southbend SB1053F Turn-X oven combines advanced convection technology, user-friendly controls, robust construction, and energy efficiency to create a kitchen appliance that meets the needs of today's fast-paced culinary environments. Its reliability and innovative features make it a valuable asset for any professional kitchen seeking to enhance productivity while delivering consistently high-quality food.
