The numerical control system firstly controls the number of axes and the number of linked axes, generally 2-5 axes; the second is the strength of manual programming functions such as graphics programming; the 2-3 dimensional simulation capability of the program; and the communication interface such as transmission Program A-232C serial port, DNC port that can feedback machine status: LAN interface with high transmission rate (Ethernet or MAP network with MMS format).
Spindle speed, power and torque are closely related to the material and process requirements of the workpiece. The accuracy of the machine tool is undoubtedly one of the most important indicators and should be higher than the corresponding precision of the machined part. To use a CNC machine tool, you must first purchase a CNC machine tool. The purchase of CNC machine tools should start from the enterprise development plan, production program, and typical parts process analysis. Determine the machine configuration, performance requirements and many other factors, such as the machining center: the type of machine tool (vertical / horizontal / vertical and horizontal) depends on the processing content. The size of the machine's mounting table and the stroke of the machine depend on the size of the workpiece, the size of the fixture and the size of the tool, the length of the tool, and the diameter of the cutter.
Tools and magazines: You must be aware of the difference between the 150 standard and the marking standard when sharing tools between machines; the size of the magazine configuration depends on the frequency of tool changes and the number of tools required to machine each part. Machine tool accuracy and standards: The shape information of the parts during pressure machining, casting, plastic pressing, etc. is transmitted by the mold, that is, the analog quantity, while the numerical control processing relies on the digital form, that is, the path of the tool space movement to transmit the information of the parts. The correctness of the tool path depends on the accuracy of the machine tool, including static geometric accuracy and positional accuracy; dynamic stiffness, thermal deformation, vibration, etc. are reflected in the machining accuracy of the parts and the process capability of mass production.

SZL series biomass-fired steam boiler is package or shop-assembled water tube boiler with double steam drum and chain grate stoker structure. 4-6 tph boiler is package boiler and 6-35 tph is shop-assembled structure, which is composed of 2 parts, upper part is heat absorbing surface and lower part is combustion equipment. The former part of boiler body is surrounded by membrane wall, its upper part connects with boiler drum and lower part connects with header, which forms a combustion chamber to absorb the radiated heat from furnace; there are dense convection tube bundle between the back side of upper and lower drum, the high temperature smoke enters a separate economizer after flushing heat absorbing surface then discharge from chimney.
