CNC universal tool grinding technology
Recent years, the tool industry is gradually cutting tools from the standard model of mass production to small batch production and more varieties of a special tool model. How to quickly stabilize the user needs to market a special tool has become a place in the tool manufacturers an important subject. Twenty years ago, is the leading CNC tool grinder began to develop its headquarters in Melbourne, Australia's ANCA (green card) Pty.Ltd company. ?
Green cards produced there are 5 types of grinder: the production of TX7 type, re-grinding with the RGT-type, threaded processing of TapX type, blade-type processing of the SBG, stamping tools of PGX-type. Here are the best-performing TX7 type tool grinder. ?
Green cards developed 5-axis control CNCTX7 +4 axis universal tool grinding machine bed developed by the company's high resin concrete, its excellent damping properties of cast iron bed is equivalent to 9 times. According to three-dimensional CAD design space for large machine tools, spindle front close to the center column rotating machinery, such spindle structure at any radius can achieve high-precision grinding, tool basic parameters in Table 1.
Table 1 TX7 basic parameters of machine tools
Tool maximum length: 300mm (the maximum length of the cutting edge 250mm)
Tool diameter: 200mm Tool maximum weight: 25kg Wheel axis motor power: 18kW (24HP) (built-in motor)
Wheel spindle: Big-plus BT40 Wheel component count: 2 Machine weight: 7500kg Feasible, high efficiency are the main functions of TX7?
(1) All axes are driven by direct
General NC tool grinder or grinding wheel spindle axis linear movement through belts are driven by the motor, drive shaft from the gear. The green card products spindle, linear motion axis and axis of rotation entirely by way of direct drive, removed all the belts and gears. Green Card companies in this area leading position.
(2) MPG-type feed? Manual pulse generator, operator can control the movements NC program for fast security testing. The use of this feature, operators can perform simple input, output and safety quick setup, thus shortening the adjustment time. ?
(3) wheel automatic replacement function? Two wheels (each including four wheel and cooling equipment) can be replaced simultaneously in the 4s. To improve accuracy, grinding wheel spindle with large Showa Precision Machinery Company clamping system. Each wheel can be adjusted coolant pipe, new wheels and coolant pipe to complete the adjustment in 2min. ?
(4) Big Plus wheel clamping system?
Showa Precision Machinery companies with large patent product?? BigPlus wheel clamping system, because both sides of contact with cone and the end to, thus ensuring high accuracy. Wheel clamping components to improve the accuracy of the tool's accuracy and performance. In this way, the full increase processing capacity of the wheel itself was extended wheel life. ?
(5) high-speed workpiece axis?
Workpiece axis high speed (3000r/min) installation can be a grinding, you can create a one-time installation of ladder drill. Workpiece axis can also be installed on the amendments high performance devices for high efficiency, high-precision correction process. This optional device can be modified to maintain tools in the long process of quality consistency.
