Rock arm milling machine
A rock arm milling machine is a machine tool that uses rock arm milling lines to easily machine any type of metallic material. It is made up of several components including a spindle, bed, guard, stance, feed mechanism and table.
The spindle is a cylindrical unit used to drive the cutting tool that is mounted on the machine. It is powered by an electric motor or a hydraulically driven unit. The movement of the spindle along the machine axis is controlled by a computer numerical control (CNC) system, which is fed with information from a part drawing or program.
The bed is the main structural part of the machine. It is stationary and provides support for the tool and spindle. It is also an essential part of the stiffness of the machine which contributes to accuracy and repeatability of the cut.
The guard, sometimes known as the sleeve, encloses the cutting area of the machine. It is designed to protect the operator from the sparks and chips residual from the machining process, and is especially important with CNC machining where the operator is not required to be in direct contact with the parts while they are machining.
The stance provides the foundation of the rock arm milling machine and allows it to be connected to the shop floor. It also provides added stability and smoothness when using higher torque cutting loads.
The feed mechanism is the part of the machine that moves the cutting tool along the cutting path of a part. This can be controlled manually or by CNC.
The table is the platform that the materials to be machined are placed on. It can be moved in different directions by hand or electronically to meet the needs of the operation.
Slide pillow milling machine
A slide pillow milling machine is a machine tool designed specifically for machining cylinder or conical shapes. It is composed of several components including a vertical spindle, a slide table, a height adjustment device, and a driven quill for depth adjustment.
The spindle is held in a vertical position and is driven by a motor or a separate control unit. It is used to rotate the cutting tool at different speed ranges and feedrates.
The slide table provides support for the cutting tool and the workpiece. It can be either manually operated or mechanically operated. It is mounted to the head and can be adjusted to different angles and lengths depending on the requirements of the part being machined.
The height adjustment device is used to adjust the distance between the cutting tool and the workpiece. It is either adjustable manually or with a dial system.
The quill is the part of the machine that regulates the depth of the cut. It is driven by a handwheel or a motor depending on the model, and can be adjusted to different depths.
These are the two main types of milling machines that are commonly used in metalworking operations. Both provide extremely precise and accurate machine parts, and can be used for a variety of applications. They are designed to help reduce the amount of downtime due to maintenance, and can offer extremely efficient machining processes.
