How To Ensure The Machining Process Efficiency Of Precision Parts | JTR
High precision components used in various industries of testing equipment – scientific instruments, mainly used in domestic scientific instruments. In the instrument industry, precision components factory provides parts processing, need to consider the corresponding technology and efficiency, as well as detailed process. So how to ensure the factory processing efficiency of precision parts and how to do precision parts processing well? Let’s take a look at the following guide.
How To Ensure Machining Efficiency Of Precision Parts 1. Laborious, rough finisher to ensure machining accuracy. The characteristics of rough machining and finish machining are different. For example, in rough machining, the workload will be relatively large, such as cutting and clamping force. Therefore, finish machining and finish machining should be carried out separately, and the processing conditions should be strictly controlled.
2. Select appropriate processing equipment. For finishing and rough machining, they have different requirements for equipment. In the rough machining process, we can choose high-precision machine tools, but in finishing, we need to choose high-performance machine tools.
3. Do precision parts processing heat treatment steps. The implementation of this process has a high impact on the processing quality, which must be paid attention to.
But with the right to enter the scientific method of precision parts processing work to meet the growing demand of enterprises, will strive to improve. So, how to do a good job in precision parts processing?
1. Choose the equipment reasonably
Rough machining of mechanical parts is mainly to cut off most of the machining allowance, and it does not need high-precision machining of mechanical parts, so rough machining should be high-power and high-precision machine tools. In the process of completion, adhere to the use of relatively high-precision machine tools.. rough, completed on different machines, can give full play to the equipment capacity, and can extend the service life of precision machine tools.You can totally be free to choose JTR CNCmachining service, they are professional in this field, with decades of working experience to support you the best service and advice.
2. In order to ensure the machining accuracy of precision parts, the coarse and fine mechanical parts are processed well respectively
Because when rough machine parts, cutting quantity, cutting force of workpiece, clamping force, heat, surface hardening of mechanical parts, significant, large internal stress in the workpiece, if rough, rough processing is completed continuously, the mechanical parts after precision will soon lose stress redistribution. It is used for machining some mechanical parts with high precision. Roughing and finishing, or aging treatment should be arranged after low temperature annealing to eliminate internal stress.
3. Heat treatment is often arranged in the process of precision parts processing
Location is as follows: Heat treatment to improve metal cutting performance, such as annealing, normalizing, tempering, set in the treatment of general mechanical parts. In order to improve the mechanical properties of the parts, such as carburizing, quenching and tempering, the mechanical parts are generally set in the above treatment. If the deformation is large after heat treatment, the process after processing should be arranged.
For some equipment produced by many machinery factories, the relationship between more precision parts will be used. When so many people will find out whether some machine parts want to be used well enough, sometimes even some bad phenomena will appear. It is necessary to use a good technology at this time, that is precision parts processing, precision parts processing. So what’s the concept, Some precision parts that have been formed can be processed well and completely, for example, some of them meet your requirements, so you don’t really need good parts inside the machine. As long as you process your parts and tell them that what you need is part of the polite words, you can get the parts you want to meet in the machine.

What is CNC Vertical Machining Center – VMC Machine Applications & Difference Between Horizontal Machining Center
CNC machining center is a highly automated multi-functional machine tool that can be divided into horizontal and vertical machining centers, what’s the difference between them? Here is the introduction to what is CNC vertical machining center (VMC) and the applications of VMC machines.
What is Vertical Machining Center – How to Define CNC Vertical Machining Center Vertical machining center (VMC) refers to the machining center of which the spindle axis and the worktable set vertically, it can perform milling, boring, drilling, tapping, thread cutting, and more operations. CNC vertical machining center is a type of Computer Numerical Control VMC that has vertically oriented spindles that approach workpiece mounted on worktable from above and equipped with tool magazine system and automatic tool changer. In CNC vertical milling center, the material to be processed will be held on the table and the cylindrical cutters oriented vertically on a spindle axis.
VMC Machine Applications & Uses Due its advantages and characteristics, [u]CNC machining[/u] center can be applied in machinery manufacturing industries with high precision and mass production requirements, such as aerospace, automobile, instrumentation, light and textile, electronic and electrical, mold making, military products, handicrafts, etc. VMC is primarily suitable for processing workpieces with complex shape, high accuracy & precision and multiple procedures. 1) Box type parts Box type CNC machining parts refers the workpiece with over one hole system and many cavities inside, mainly applied in machine tool, car and airplane, like engine block, gearbox, spindle box, diesel engine block, gear pump shell, etc. When using a vertical machining center, 60% – 95% of the process of ordinary machine tools can be completed in one-time clamping. In addition, the CNC VMC has high accuracy and efficiency, rigidity and automatic tool changing device, as long as the process flow is well formulated, proper fixtures and tools used, many problems of box types parts machining can be solved.
2) Complex curved parts In the aviation and transportation industry, the parts with the complex curved surface are widely used, such as cams, integral impellers of engines, propellers, mold cavities, etc. This kind of parts with a complex curve, surface contour, or box or casing parts with closed inner cavity are difficult to achieve the predetermined machining accuracy and detect by conventional machine tools or precision casting. A multi-axis machining center with automatic programming technology and special tools, can greatly improve its production efficiency and ensure the shape accuracy of the surface, making the automatic machining of complex parts become easy.
3) Special or irregular shaped parts Irregular machined parts have special shapes, most of them need multi-point mixed processing of point, line and face, such as bracket, base, etc. When machining special -shaped components, the more complex the shape is, the higher the accuracy required, while VMC shows its benefits at such moment.
4) Board, sleeve and plate parts This kind of workpiece often includes keyway and radial hole. The end face with hole system or curved plate and shaft, like shaft sleeve, plate with many holes, like motor covers, often uses vertical machining center; and horizontal machining centers are often used for parts with radial holes.
5) New parts in trial production The machining center has high adaptability and flexibility. When the machining object is changed, you only need to build and input new programs, even modify some program segments or utilize some special instructions sometimes. For example, use the zoom function can realize machining of parts with the same shape but different sizes, which provides great convenience for a single piece, small-batch, multi-variety production, and new product trial, and greatly shortens the production preparation and trial manufacturing cycle.
Difference Between Horizontal and Vertical Machining Centers 1) Vertical machining center refers to the machining center with a vertical spindle while the spindle of the horizontal machining center is in horizontal. 2) The worktable of the vertical machining center is rectangular and has no indexing rotation function. While horizontal center usually has a rotating table with automatic indexing. 3) The horizontal machining center is easier to remove chips and reduce the damage to tools. 4) The vertical machining center has a simpler structure, smaller floor area, and lower price.

Classification of CNC Machine & System – What are the Types of CNC Machines
CNC machining is a manufacturing process that programmed software to direct the motions, the classification of CNC machine indicates the types of the equipment and the works they can do. How many types of CNC machines are there? The following content will introduce each kind of CNC machine tool, you can find the difference between them.
Classification of CNC Machine - What are the Types of CNC Machines CNC (Computer Numerical Control) Machine tool is an automatic machine tool equipped with a program control system, can achieve the purpose of complex, precision, small-batch and multiple CNC machining parts processing and production. There are many types of CNC machines, which can be classified into the following categories based on different methods.
1. Functions (Parts)
According to the functions or types of machined parts, CNC machines can be classified into five types: CNC milling machines, CNC lathes, CNC drilling machines, CNC plasma cutters, and CNC grinders.
– [u]CNC milling[/u] machines: used to create shapes, slots, holes, notches, grooves, pockets, and specialty faces, and perform the machining process of manufacturing CNC milling parts, the rotary cutting tools on the mill to remove material from the stationary workpiece.
– CNC lathes: used to manufacture cylindrical objects, and perform the process of producing CNC turning parts, a cutting tool will shape the workpiece while the material block is turning rapidly on a spindle.
– CNC drilling machines: used to drill hole in the workpiece, the tool can locate the position for drilling quickly and accurately, sophisticated drilling machines can also perform reaming, counterboring, and tapping holes.
– CNC plasma cutters: a machine carries a plasma torch, which is for cutting metals, involves cutting through electrically conductive materials by an accelerated jet of hot plasma.
– CNC grinders: a machine uses a rotary wheel to abrade the material by grinding or grating it into the desired shape, it’s easier to program than milling machines and lathes.
2. Motion type
Classification by motion, CNC machines can be divided into point to point systems and contouring systems.
– Point to point systems: the material and tool are placed at certain fixed relative positions at which they retaining until the cutter finishes the process and retracts, this type equipment including drilling, boring and tapping machines.
– Contouring systems: the machine tool cuts the material following a contour of a part, so it works in a continuous path, this type equipment including lathes, mills and routing machines.
3. Number of Axis
When classified by the number of axis, CNC machines can generally be divided into five groups: 2-axis machines, 2.5-axis machines, 3-axis machines, 4-axis machines and 5-axis machines.
– 2-axis CNC machines: a machines gives access to only two axis, like the lathe machines, the tool moves in 2 directions, like X and Z.
– 2.5-axis CNC machines: is also a 3-axis system but the movement is not in three-dimensional, the X and Y-axis moved to the position first and then the third axis starts to work, such as the drilling and tapping machines.
– 3-axis CNC machines: three axes (X, Y and Z) move simultaneously in three- dimensional, it’s the most widely used and versatile machine that can achieve high accuracy and precision, can be used for automatic/interactive operation, milling slots, drilling holes, and cutting sharp edges.
– 4-axis CNC machines: the 3-axis machine with one more rotation on A-axis or B-axis, the common example is a vertical machine or horizontal machine. In the case of 4-axis machining, milling is performed on the additional axis, while the operation on the X, Y and Z is the same as the 3-axis system, and the rotation on the A or B axis is around the X-axis.
– 5-axis CNC machines: the 3-axis machine with extra rotation along two directions (Y and Z) on A-axis and B-axis, the rotations are respectively given by the bed and spindle movement (pivot point). 5-axis machines are advanced CNC machines and its multidimensional rotation and tool movement allows the creation of precise and intricate parts due to the improved access to undercuts and deep pockets, unparalleled finish and speed, often used for high-level applications, like aerospace parts, artificial bones, titanium pieces, oil and gas machine parts, military products and more.
4. Control loop
The classification of CNC machines according to the control loop can get the types: open loop system and closed loop system.
– Open-loop CNC machine refers to a system where the communication between the controller system and the motor is one way. The process for an open-loop system is simple, CNC software creates the information with necessary step and direction signals based on the user’s purpose, the computer relays this information to the controller which then energizes the motor, and no feedback. Open-loop CNC machines use stepper motors.
– Closed-loop CNC machine has a feedback system to monitor the output of the motors, also able to correct errors in position, velocity, and acceleration. The feedback can be returned to the CNC controller or computer, and the former type is more common, the system with feedback fed into the signal generator or computer usually exists in high-end machines.
