Turning, Drilling & Milling

Machining at Legitimate Engineering involves a number of operations that must occur in a predetermined sequence to obtain the best results possible and we cover a few of these operations which are: Turning, Drilling, and Milling.

Machining is a highly versatile process in the manufacturing industry. Various types of materials may be machined using the three methods mentioned above and at Legitimate Engineering we offer exceptional quality turning, drilling, and milling capabilities to help our customers meet their industrial requirements.

Turning Operations

This is where the workpiece is rotated as the cutting tool travels in a linear direction. This produces a cylindrical shape. Often with turning operations, a lathe is the preferred machine to use.

About Us

As with many machining operations, turning is carried out either automatically or manually. Manual turning operations do require constant supervision. However, automatic turning operations do not. Through the use of CNC, all of the necessary movements, tooling adjustments, and speeds are programmed, with these instructions delivered to the lathe for completion of the task. CNC enables the completion efficient and consistent production runs.

Drilling Operations

Drilling produces a round hole in a workpiece. A tapping or drill press machine performs drilling operations. However, drilling can also be handled with a milling machine. When machining a workpiece, chips are the waste material produced during the machining process. The way the drill bit is shaped enables chips to fall away from the workpiece.

Leading-off or drifting is reduced when the drill bit is placed perpendicular to the workpiece. For greater precision, before drilling, center drill operation can be added. Angular drilling is often required and requires a special work-holding tooling. Additional drawing options include the use of multiple axes with a CNC machine or the rotation of the head on a manual machine.

Milling Operations

With milling, rotary cutters are often used to eliminate material from a workpiece. The two major types of milling operations are peripheral milling and face milling. Peripheral milling cuts deep slots, gear teeth, and threads. Face milling cuts flat bottomed cavities and flat surfaces into the workpiece using a feed that can be either vertical or horizontal.

A workpiece may be cut in one of two ways. The climb milling method feeds the workpiece in the direction of the cutter rotation, and this is the desirable method for CNC milling operations. Conventional milling feeds the workpiece in the direction opposite cutter rotation, and this method is recommended when using manual milling equipment.

After a workpiece is already machined, milling is used as a secondary process to help define features of the workpiece, including slots, contours, pockets, and holes, and provide a finishing coat.

About Us

Fabrication

Metal fabrication is a somewhat broad term for several types of fabrication processes. At Legitimate Engineering Cutting, punching, forming, shearing, stamping, welding are common fabrication techniques we use to shape, cut, or mold raw metal material into a final product.
The process of Fabrication is used in making mass-produced products or custom designs.
Whether mass-produced or custom designed, the end products are made with a wide range of metals and their alloys—stainless steel, carbon steel, aluminum, copper, brass to name a few. In our industrial fabrication processes, one or some of the following methods will be used to finish or produce a part or end product:

Our Common Methods of Fabrication

Cutting

The cutting of a metal workpiece is a common fabrication technique in which the material is split or cut into smaller sections. Cutting can be used as a first step in a much larger fabrication process or the only step necessary in the process. The old days of sawing have been superseded by modern forms of cutting where we utilize state-of-the-art machinery which includes power tools and computer numerical computer (CNC) cutters. We are very resourceful and therefore no job is too big or small for us with methods ranging from laser cutting, waterjet cutting, power scissors to plasma arc cutting.

About Us

Welding

One of the more common fabrication processes commonly used at Legitimate Engineering, welding is the art of joining two or more pieces of metal together utilizing a combination of heat and pressure. Metals can vary in shape or size. Our 2 main types of welding procedures are CO2 & Arc Welding.

Other Fabrication methods includes:

Forming
Punching

Internal & External Keyways

Keyways in broaching.

Keyway broaches are tools in the shape of a bar that have cutting teeth that are capable of creating precise keyways in the boreholes of washers, gears, pulleys, and many other components mounted on shafts, so they can be locked into the shaft

About Us

Keyway milling.

Keyway milling is the cutting of a keyway along the axis of the cylindrical surface of shafts or other items. Our Keyway milling machines allow us to cut new or re-cut worn keyways in shafts as little as 6mm outside diameter.
