- Chip formation
Drilling – the most common machining process
According to estimates, at least 75% of all material removed through machining services Toronto are achieved through drilling operations. Drilling involves the creation of holes with right circular cylinders by using a twist drill, a rotary cutting tool with two cutting edges and two flutes that are grooved formed in the body to provide cutting lips for the removal of chips and to allow the coolants or cutting fluids to reach the cutting action. When the proper type of drill is chosen for high volume applications it can result into significant cost savings.
Turning on a machine called a lathe
The lathe is an important tool for machining services Toronto. When turning is performed on the lathe the tool is stationary and the work piece is rotating while mounted on a chuck. Since lathes are designed solely for turning operations, the precise control of the cutting tool results into tight tolerances. When integrated with CNC technology, lathes meet the needs of modern machining services Toronto due to their wide range of capabilities. Dual-spindle models and Y-axis capabilities boost production rates and minimize setups for machining processes.
Milling as a fundamental process in machining
Milling cannot be considered to be as accurate as grinding or turning but it is versatile for basic machining processes especially when rigid fixturing is implemented. In manual machining, milling is important in the fabrication of any object that is not axially symmetric. There is a wide range of milling machines used for machining services Toronto ranging from manual light duty machines to huge CNC machines for milling parts that are hundreds of feet long. Manual milling machines are common in machine shops that specialize in low volume parts and prototypes that require quick fabrication.
Grinding - a finishing process in machining
Grinding improves surface finish, abrade hard materials and tighten tolerances on flat and cylindrical surfaces through the removal of a small amount of material. An abrasive material is usually used to abrade materials from a surface similar to the process of sanding. Grinding is an economical process when used on hard materials and to produce flatness tolerances of less than ±0.0025mm (±0.0001”) on a 127 x 127mm (5” x 5”) steel surface if the surface is adequately supported.
Chip formation in machining
Chip formation is the same in most machining processes and it has been properly researched in order to determine solutions for speeds, feeds and other parameters. With the speed of CNC machining, it has become important to provide algorithms for speeds and feeds. Previously, these were only determined through the feel of the machinist.
