I. scope of application:

We produce CNC horizontal thick box machine, mainly for mold frame, mould, milling processing industry is used to open the box, rough and finish machining machine parts of irregular shape, when machining parts, iron is not sharpen in simple is not easy to damage the tool, for a variety of spatial orientation of milling, and can be used in the mold industry is doing lock, clamp slot, cavity, drill hole for hoist, etc.



Ii. Machine structure and performance


1. The overall structure of the machine tool is composed of four castings: base, saddle, table and column.

2. The movement of the saddle and the base is supported by four square hard rails, and the inner chamber of the bed is arranged with intensive honeycomb well-shaped rib plate, so as to ensure sufficient rigid strength and stability of the machine when it is running.

3. The main material of the machine tool is made of high strength HT250 cast iron and resin sand, and the castings have a complete three times of artificial aging treatment, so as to eliminate the residual internal stress and ensure the stability of the machine tool's rigid strength without deformation.

4. The machine tool operating system adopts mitsubishi M70B or fanake 0i mate MD, the operating surface version is beautiful and generous, easy to use, X, Y, Z three-position configuration handwheel pulse control for easy operation.



Iii. Main drive:


1. The milling head adopts the complete set of milling head imported from Taiwan, adopts the spindle gear transmission combined with frequency conversion speed adjustment structure up to 3000rpm/min, the transmission chain is short, with the best spindle accuracy, ensure the spindle running fast, low noise, long service life.

2. Spindle adopts precision roller and bevel contact spindle bearing, the supporting span is large, the spindle rigidity is good, the running is stable, the precision is good, the spindle component is an independent part, the assembly manufacturing process is good, the adjustment bearing preload is convenient and reliable, the maintenance is convenient.



Iv. Guide rail


All fixed guide rail through high frequency quenching heat treatment, wear resistance, high precision, high operation sensitivity. The combined structure has good rigidity, low friction coefficient, high motion sensitivity and excellent performance. Large bearing capacity, can withstand strong heavy cutting, and the accuracy of the machine tool stability is excellent, long service life.



V. feeding machinery:


X, Y, Z direction feed adopts Taiwan TBI ball screw drive, greatly improve the driving force and machining accuracy.



Vi. Performance characteristics of main electrical control parts:


1. X, Y, Z three-way feed servo drive motor, advanced performance, reliable work, easy to operate.

2. X, Y, Z three feed control with fast movement and handwheel control, work feed micro feed conversion, easy to operate.



Vii. Safety protection:


1. X, Y and Z guide rails are protected by a telescopic cover with stainless iron thickness (2.5mm) to ensure the working life of the rail and screw.

2. All moving wire pipes adopt non-metal chain device for safety protection.

3. Main motor feed motor are equipped with overload and overheating electrical protection function, three axis feed stroke high limit and limit switch, mechanical work safe and reliable.
