Investment casting is a metal forming process that generally involves using a wax pattern surrounded by a ceramic shell to form a ceramic mold. Once the ceramic shell is dry, the wax is melted out, and the ceramic mold is formed.

Determining the cutting speed for the precision machine is based on the peripheral speed of the workpiece when it is fed past the rotating cutting tool. This measurement is shown as feet per minute or meters per minute based on the cutting speed velocity. The cutting feed rate and the cutting speed helps to determine the power requirements of the tool to ensure it is moving at a rate that is appropriately defined based on how much material is cut away in one rotational pass.

These three parameters focus on how the hydraulic part is cut. Cutting speed represents how fast the metal is removed from the workpiece. Cutting feed focuses on how far the cutting spindle travels across the metal part during one full rotation of the tool. As the cutting tool moves into the metal part, the distance that it moves is the depth of cut. These three parameters ensure accuracy of the finished workpiece and the surface finish.

Vacuum deposition systems manufactured by Vac Coat Ltd., using Physical Vapor Deposition coating techniques, have made it possible for users to deposit a wide range of materials on different substrates, depending on their desired performance. The possibility of using two PVD techniques in one vacuum deposition system has eliminated the problems of buying different machines for deposition of different materials. Versatile deposition system to do sputtering and thermal evaporation deposition DST3-T model and coating system versatile to do sputtering and carbon coating from carbon thread and rod in DSCR and DSCT models, including multifunctional models of Vac Coat Ltd. products.

Atom-to-atom deposition in PVD allows control of density, stoichiometry and atomic structure of the thin film. By using the appropriate materials and creating special conditions during the coating process, coatings with desirable properties such as hardness, lubricity and good adhesion can be created on various surfaces. For example, some hard coatings can reduce friction and protect their underside from damage.

The field of application of these friction-reducing coatings is very wide. The aerospace and defense industries, automobiles, cutting tools, rollers and many other cases in which friction reduction is very important, are all applications of coatings created by the PVD method. Titanium nitride coatings and the like are also among the coatings that, in addition to being beautiful, have a high resistance to abrasion and corrosion and are used to cover building valves and door handles that are in constant contact with the hand.

Cobalt can easily alloy with tungsten boats during thermal evaporation, so the deposited layer may not preserve cobalt magnetic properties. Using an alumina coated tungsten boat to prevent alloying process can solve the problem. However, the boat’s lifetime is short (less than 3 runs) and should be treated gently since it gets brittle after the deposition.

The parameter impacts the performance and efficiency of the precision machining process. To select the right depth of cut, the following factors are taken into consideration:

Turning machines used to produce hydraulic parts provide immense benefits. These machines can produce hydraulic parts such as pistons and cylinder assemblies quickly while being cost-effective. The CNC lathe machine works by removing materials from the part at specific speeds as the equipment rotates the workpiece until reaching a specific depth. When creating the workpiece with precision machining processes, common issues such as friction, chip formation, heat generation or conductivity to the metal may occur. These problems may negatively impact the metal’s grain structure to cause damage, creating an inaccurate workpiece.

Surface treatment generally refers to a process to alter an object’s surface to enhance its appearance or functional properties. At Impro, surface treatment refers to electroplating, one of the most widely-used surface treatment techniques that provide broad coverage of coating metals and high cost-efficiency.

Precision machining is a process to produce accurate components with high tolerances and excellent surface quality by removing materials from a workpiece. It involves a combination of several or all of the turning, milling, drilling, gear cutting, honing, grinding processes, and other steps.

Sand casting is a metal forming process in which a mold is first formed from a three-dimensional pattern of sand, and molten metal is poured into the mold cavity for solidification.

Physical Vapor Deposition (PVD) is a set of vacuum deposition methods in which a solid material vaporizes in a vacuum environment and is deposit on the substrate as a thin film. The most common methods of PVD are Sputtering and Thermal Evaporation. Because in the PVD process, the material is transported and accumulated atom-by-atom or molecule by molecule in a vacuum to the substrate surface, the deposited films have high purity and efficiency that for many applications compared to other deposition methods are preferred.

Hydraulic machines are used on industrial, commercial, and public applications to perform a range of tasks. They are found in heavy equipment, food processing, aircraft, and other equipment. To create hydraulic components, precision machine tools are often used. These consist of machine tools such as CNC lathes.

Physical vapour deposition coatingpros and cons

Significant improvements to the workpiece can be made with the use of a CNC lathe machine. A CNC lathe can make a rougher finish by having the preprogrammed machine lower the depth of the cut parameter. The machine may also remove more materials and speed up the production process with an increase to the depth of the cut parameter.

The PVD method involves environmentally friendly processes and, in comparison with other coating methods such as chemical plating, drastically reduces the use of toxic raw materials, chemical reactions, and disposal of chemicals.

Global trade policies, supply chain issues, transportation and shipping capacity shortage are among many factors that impact customers in different regions around the world. It can impede customer demand, slow down supply chain capabilities and raise costs. Localized production and near-sourcing are the growing trends. To offset the hurdles and provide more vertically integrated solutions to North American customers, Impro’s high precision machining and casting operations are expanding into Mexico.

For example, in the construction of the most important part of any microchip and semiconductor device, durable protective layers, optical lenses, solar panels and many parts and medical devices, the PVD thin film provides basic functional characteristics for the final product. In general, wherever there is a need for coating with very thin, pure, durable and clean thin films, PVD is the key to solving the problem.

CNC lathes minimize these issues with preprogrammed parameters that focus on the speed, feed, and depth of cut performed on the part.

When figuring out these two parameters to preprogram into the CNC lathe, the hardness of the metal and how rigid the workpiece is must be taken into account. If using too high of a cutting speed or feed for a soft metal, the tool may end up removing too much in one pass. Cutting a hard metal at too low of a speed or feed rate may not provide the desired surface finish. One key aspect to keep in mind is that the tool’s speed must increase when the hardness and strength of the metal increases.

The depth of cut parameter focuses on the tertiary cutting motion of the tool as the tool is pushed deeper into the workpiece to the specified depth. This parameter is measured as thousandths of an inch or thousandths of millimeters. The depth of cut will usually vary between 0.1 to 1.0 mm.
