Product details
Huadian CNC specializes in producing valve processing machine tools, valve processing special machines, and valve processing equipment, which are used for turning and drilling of forged steel, cast steel (carbon steel) gate valves, globe valves, butterfly valves, etc. The cutting amount can reach 10mm, and the equipment is efficient, convenient, stable, and reliable.
Machine tool usage
The gate groove gantry milling machine is mainly used for processing valve gate parts. It can continuously complete precise machining of milling, expanding, and boring in one clamping, and the machining is programmed to shorten the production cycle, thereby enabling users to obtain good economic benefits.
Main features of machine tools
The gate groove gantry milling machine adopts a horizontal layout, with the worktable performing X-directional linear reciprocating motion. The bidirectional gate groove is symmetrically processed by double cutting heads, and the unidirectional gate groove is processed vertically and horizontally. The worktable is parallel to the guide rail surface. There are two workstations, one for milling double-sided gate slots and one for milling single-sided gate slots. The up and down movement of the bidirectional blade head is manually adjusted, the forward and backward movement is automatic, the up and down movement of the unidirectional blade head is automatic, and the left, right, forward and backward movement is fixed.
Main structure of machine tool
The gate groove gantry milling machine mainly consists of large parts such as the bed, worktable, slide seat, spindle box, etc., all of which are made of high-strength cast iron material, shaped with resin sand technology, and undergo two aging treatments to eliminate stress.
1. Bed frame
The bed body is made of high-quality casting and has undergone three artificial aging tempering treatments. The guide rail surface is treated with ultrasonic quenching, and the design structure is reasonable to ensure the rigidity, accuracy, and stability of the machine tool.
2. Processing preparation:
1). After the workpiece is placed on the fixture, the machining preparation work is completed by hydraulic compression.
2). During processing, the X-direction skateboard moves in a straight line to drive the workpiece first through the double-sided milling head. The double-sided milling head simultaneously processes the guide grooves of both sides of the gate plate. After processing, it continues to move to the single-sided groove position of the gate plate for single-sided groove processing.
3). Debugging is required before processing, and the debugging method is manual debugging. The types of debugging include changing fixtures, adjusting the distance of double-sided milling tools, and adjusting the height of double-sided milling tools. The debugging steps for single-sided milling tools and double-sided milling tools are the same.
4). All cutting tools of this equipment are made of molded tools, with standard 7:24 BT series tool holders and standard ER series tool holders for docking fixtures.
3. Drag the system
The workstation guide rail pair adopts high-strength cast iron guide rails, with electronic centralized lubrication, low dynamic and static friction, high sensitivity, and high-precision private server motor drive to improve the accuracy and stability of the machine tool.
The two axis servo motor is directly coupled with a high-precision ball screw through an elastic coupling, reducing intermediate links and achieving seamless transmission, flexible feed, accurate positioning, and high transmission accuracy.
4. Spindle assembly
The spindle assembly is produced by professional domestic manufacturers and has high precision and rigidity. The bearings are equipped with BT series P4 grade spindles. After the entire spindle is assembled under constant temperature conditions, it has passed dynamic balance correction and running in testing, which improves the service life and high reliability of the entire spindle.
5. Knife handle
Adopting integrated forging test, installed in the BT40/50/7:24 taper hole, the tool holder can be directly replaced or the tool clamped by the tool holder can be replaced during tool change, and the tool change process is fast and accurate.
6. Cutting cooling system
Equipped with a large flow cooling pump and a large capacity water tank to fully ensure circulating cooling. Cooling pump power: 0.9Kw, pressure: 3bar.
Cooling is mainly based on water cooling, and the cooling process can be controlled through M code or control panel.
Configure a cleaning air gun to clean the machine tool.
7. Pneumatic system
Pneumatic triple components can filter impurities and moisture in the gas source, preventing impure gases from damaging and corroding machine tool components. The solenoid valve group is controlled by PLC program. (Customer optional)
8. Machine tool protection
The machine tool adopts a protective room that meets safety standards, which not only prevents coolant splashing, but also ensures safe operation and pleasant appearance.
9. Lubrication system
The guide rail, ball screw pair, and supporting bearings all adopt centralized automatic thin oil lubrication. Each node is equipped with a quantitative oil separator, which injects oil to each lubrication part at a fixed time and quantity to ensure uniform lubrication of each sliding surface, effectively reducing frictional resistance, improving motion accuracy, and ensuring the service life of the ball screw pair and guide rail.
