CZPT Summary:
GY sequence machine instrument is made up of moving desk and beam and fastened column.Main structural parts are manufactured of substantial power solid iron and phenotic sand molding with the good shock absorption and thermal stability.The construction of the entire machine is characterised by the substantial rigidity and substantial trustworthiness.It is suitable for the processing of weighty and further-large simple areas in the industries of metallurgy,railway,hefty  machine, shipbuilding , electrical energy technology, vehicle , aviation, printing and mold ,especially the CNC processing of all kinds of airplane ,curved floor,place curved surface area and hole with big excess weight and long height .It is extensively applied in the tough and wonderful processing of complex elements of plate,box and chassis.
 
Construction and performance:
1.The equipment tool can end four-axis linkage curved surface processing and rigid tapping .The addition of accent milling head can satisfy the demand from customers of five-encounter processing.It can incorporate the accent milling head in accordance to customers’demand of processing and comprehend the five-face processing by 1 time of clamping accordingly.The spindle of boring and milling head is pushed by AC spindle servo motor .The output terminal of spindle servo motor is right linked to the automated gear box with the best and decrease equipment.The exterior coder can realize the fixed-direction and rigid tapping of spindle.
two.Utilize the pc-aided engineering (CAE) technique to complete the optimized construction design and style and improve the trustworthiness of device device ,and the finite element strategy(FEM) to consider the scientfic investigation and optimization of design and style construction,which can assure the rigidity and balance of the entire equipment composition.
3.Utilize two-moments growing older therapy for the cast to guarantee the complete release of internal anxiety and the precision persistence of the device instrument.
four.The operator can get the proper-and-remaining and vertical adjustment for the procedure box in the course of the processing as essential.
5.The hydraulic and electrical control methods are located in the maintenance system in the again of the beam,hassle-free for the servicing.
6.Each sides are equipped with the chain-kind chip conveyor ,which can gather the scrap iron following the processing and transfer it to the cart in the entrance of the machine device.
 
Xihu (West Lake) Dis. Type:
1.Xihu (West Lake) Dis. surfaces of X,Y and W-axis all undertake the injection molding complex to enhance their precision and services existence.
two.Z-axis when getting equipped with the sq. ram,it adopts the rectangle sliding guidebook.
three.When becoming geared up with the whole-wrapped slideing block,it adopts the static-pressure manual.
four.X-axis adopts the constant stream static strain manual with the substantial bearing capability,powerful skills of shock proof and shock absorption,good precision balance and extended support daily life.
5.The fastened displacement multi-stage pump supplies the hydraulic oil with the continual circulation for the continual circulation static-stress manual.
six.The beam adopts the composite framework of rectangle up-and-down phase solid information and rolling guidebook to neutralize and disturbing second triggered by the offset of heart of gravity of spindle box’s dull milling head and traverse slide .The higher manual and traverse slide undertake the numerous rolling mechanism with the mechanical unloading structure,Y-axis traverse slide ,transverse guide and slide wedge all adopt the filming treatment method to improve the precision and provider existence.
7.CZPT lock mechanism of beam and vertical ram information.
    
Feeding CZPT:
one.Y-axis adopts AC servo motor immediate-related with the precision earth reduction box to generate the ball screw.
two.GY-40B is outfitted with the screw supporting unit,which can steer clear of the distorted slipping of screw rod influenced by the gravity.It can be equipped with double gear-rack gear mechanism optionally to eradicate the backlash by the electrical handle and obtain the linear movement of transmission equipment and rack toothing driven shaft.
three.W-axis is outfitted with the reduction box and motor with the inside contracting brake to assure the balance of beam during the processing.
4.Four axes can all undertake the precision grating scale to comprehend the totally-enclosed situation opinions and assure the precision of spot and recurring location,where two sets of grating scales on W-axis can guarantee the synchronous motion of the beam.
5.X-axis rack and gear transmission is outfitted with the double equipment mechanical backlash-removing reduction box.It can adopt double equipment and rack electric powered management for the backlash elimination optionally.
                           
Ram and Spindle: 
1.Spindle adopts the “gripping-kind”tension which can automatically tighten up the areas.The mechanism of tool holder pressure is the disc spring tension and hydraulic unlock.
two.The ram and milling head spindle has the purpose of electricity defense.This sort of perform can set the limit of spindle’s maximal functioning electricity .When the vertical ram extends out completely or has the diverse accent milling heads,it can set the electrical power limitation in accordance to the extended ram or peak power output of relevant accessory milling head,which can assure that the ram can increase out completely or the processing protection when using the distinct accent milling heads to avoid the overloading operations.
three.The vertical ram adopts the nodular graphite cast iron with the CZPT alternative of rectangular information sq. ram.In circumstance of necessitating the massive torque output,it can undertake the complete-wrapped sq. ram optionally.
four.The ram is equipped with the equalizer to minimize the loading of Z-axis screw and lengthen its service lifestyle.             5.It can be geared up with the dull and milling spindle with the large torque output.Used configurations:high energy spindle motor ,two-phase world equipment reduction box(continuous temperature and lubrication by oil circulation),rigid coupling,huge torque immediate-linked spindle,continuous temperature and oil circulation cooling. It adopts the consistent temperature oil cooler to handle the temperature increase of soindle and reduction box.     

CZPT Technique:
one.CZPT and lubrication sytem security.This technique has purpose of stress relay protection,voltage-decline security of lubrication duct,alarming protection of oil fluid blockage and oil temperature pretection.
two.The hydraulic technique controls the clamping and releasing of spindle,the grabbing of accent head,hydeaulic balance of Z-axis and clamping and releasing of guidebook.The hydraulic program possesses the features of two-stage filtration and minimal-oil alarming.
3.The static stress tank is controlled by the constant temperature.Utilize the centralized lubrication for the times and calculated lubrication of every axis.
        
Resource Magazine and Accessory Milling Head:
one.It can established all types of accessory milling heads grabbed manually or automatically as required. It can also be geared up with the accessory head journal that alterations the accessory milling heads immediately and therefore enlarges the technique scope of machine resource processing. 
two.Incorporate the instrument journal in the still left column of equipment instrument.Established equipment in the magazine according to the essential processing method .Management the ram to the instrument-adjust stage by the system.The resource-adjust holder finishes the automatic tool-adjust.
