How to Choose a CNC System CNC Machine Tool - CNC Tooling Options

(1) Type of selection

According to the type of CNC machine tool to select the appropriate CNC device, in general, the CNC device is suitable for automobiles, drilling, boring, milling, milling, stamping, EDM cutting and other types of processing, should be targeted for selection.

{CNC stands for computer-numerical control. The development towards the present condition started with NC, or numerical control merely. The initial NC machines were actually built in the 40s as well as 50s. These machines based upon existing resources yet with some alterations. Motors moved based upon the informational input given to them using drilled strip. The code was personally drilled in to information memory cards. In the 50s, the very first steps towards CNC machining were carried out.

(2) Performance selection

Different CNC devices, the performance varies greatly, the number of control axes has a single axis, two axes, three axes, four axes, five axes, even more than 10 axes, more than 20 axes, the number of link shafts is more than 2 or 3 axes, speed highest feed with 10 m / min, 15 m / min, 24 m / min, 240 m / min. The resolutions are 0.01 mm, 0.001 mm, and 0.0001 mm. This indicator is different, the price is different, must be based on the actual needs of the machine tool, such as general rotation processing select 2 axes or 4 axes (double blade frame) control, processing aircraft parts select more than 3 connection axes. Don't chase the latest highs, it must make sense of choice.

(3) Function selection

A CNC system has many functions, including basic functions - those required by CNC devices; Selection function - a function for the user to select. Some of the functions selected are to solve different processing objects, some to improve processing quality, some to facilitate programming, and some to improve operation and maintenance performance. Several selection functions are related, and to choose one you have to choose another. Therefore, according to the machine tool design requirements to choose, do not add analysis, select the function of too many steps, and the relevant function of the omission, making the CNC machine tool function reduced, causing unnecessary losses.

There are two types of controllers that can be programmed in the selection function: built-in and independent. It is better to choose an outfit model, it has a different model, want to choose according to the point of the input-output signal between the CNC device and machine tools above all. The point that chooses should be a practical point pen want a few more, the need that the cup can add and change the control performance. The next step is to estimate sequential program sizes and select storage capacity. As machine tool complexity increases, program storage capacity increases. There are processing times, instruction functions, timers, counters, internal relays and other technical specifications, the number must also meet design requirements.

(4) Price options

Different countries, different CNC device manufacturers, production of different product specifications, prices are very different, must meet the type of control, performance, function selection based on a comprehensive analysis of price performance rather than high price of CNC devices, to reduce costs.

(5) Selection of technical services

In the selection of CNC equipment according to technical requirements, but also taking into account the credibility of the manufacturer, product use instructions and other complete documents, can provide programming training to users, operation and maintenance personnel. There is no department-specific technical service to provide timely parts and maintenance services for a long time, so as to give full play to technical and economic benefits.
