Technical parameters of PDCE3226 dual-station CNC gantry machining center
2025-03-30
The overall structure of this equipment is a gantry structure. The overall components include a bed, two columns, one beam, one Y-axis, one Z-axis, one cutting power system, one disc-type tool magazine, and two machining stations. Each machining station consists of a worktable, rotary tooling, and auxiliary support mechanisms. The bed, columns, and beam form a high-strength "U"-shaped gantry structure. The linear axes (worktable running direction) of the two stations are defined as (X-axis) and (X1-axis), and the rotary tooling is defined as A-axis and A1-axis. The two stations operate in an alternating cycle. For example, when station 1 is machining, station 2 moves to the front of the machine, where it is in the waiting area. Workers load and align the workpiece at station 2, and the cycle repeats. To avoid tool vibration during machining, each station has an auxiliary support mechanism. This avoids wasting idle machine time, thus the productivity of one machine is approximately 1.5 times that of a single-station machine, thereby improving production efficiency.
1. The main components are designed using the world's most advanced computer technology and optimized finite element analysis methods to ensure that the machine components can bear the maximum load. The design is reasonable, and the materials are carefully selected. All castings use high-strength HT300 close-grained cast iron, resulting in excellent rigidity, stability, and precision retention, making it particularly suitable for heavy cutting. All large castings undergo rigorous annealing treatment followed by long-term natural aging to completely eliminate internal stress, greatly improving the overall machine precision. The processed parts have excellent geometric dimensional accuracy. Using Meehanite (close-grained) castings, one-piece casting, wear-resistant, and after internal stress relaxation treatment, it achieves high vibration resistance, with shock absorption capacity 10 times higher than ordinary cast iron, improving machine stability.
2. Columns, Beam
Extra-large column structure. The columns adopt a new large column design, increasing the contact area with the ground, improving rigidity and stability. The extra-large beam is a stepped structure, with reinforced rib design inside the beam, which helps to significantly improve structural rigidity and provide stable support for the spindle head, with excellent rigidity.
3. Spindle Box, Spindle
The original spindle box adopts a special design with a high-strength, high-rigidity cage and keel rib structure. The spindle gearbox uses a gearbox transmission The maximum speed is 6000 rpm, using (15/18.5kw) New generation spindle motor Suitable for high-speed and heavy cutting. The spindle uses Φ100mm spindle, chromium molybdenum alloy steel material, after tempering, rough and fine machining, carburizing, aging treatment, and precision grinding; high precision, strong rigidity, not easy to deform 。 After assembly, the spindle undergoes dynamic balancing tests. The spindle has a center water outlet function.
4. Worktable
The base of this equipment is designed with four rails, divided into two groups on the left and right. Each group of guide rails supports a super-rigid worktable. Each worktable is a station and can be independently servo-driven. The height from the worktable surface to the slider surface is 275mm, and it is supported by double ribs, high load-bearing, and not easy to deform, ensuring long-term stability of precision. (The two worktables can be effectively connected and fixed or a 100mm thick "T"-slot worktable can be added to form a 3000mm*2100mm worktable, making the X-axis and X1-axis a dual-drive, gap-eliminating linear axis, further improving precision.)
5. Guide Rail
The X-axis and X1-axis each use one set (two) 55mm Taiwan HIWIN roller linear guide rails, with low frictional resistance, more suitable for heavy workpiece machining, X axis, every 740mm interval on each linear rail one slider. The Y-axis beam uses 65mm+55mm Taiwan HIWIN roller linear guide rails, with 55mm upper and 65mm lower linear rails, each with 3 sliders to increase the rigidity of the spindle head. The Z-axis hardened rail has a covering surface of 1200MM to ensure the rigidity of the spindle during heavy cutting. X 、 Y 、 The Z-axis uses Taiwan HIWIN, C3 grade precision ball screw and P4 grade bearings , with good positioning accuracy. The ball screw is protected by a sheet metal enclosed cover, not easily affected by cutting fluid and chips. Each axis uses a servo system drive, with fast transmission, stable precision, elimination of backlash, improved torsional rigidity, allowing for non-parallel angles, elimination of axial errors, etc., significantly improving the machine's positioning accuracy.
Screw: X = Φ63mm Y = Φ63mm Z = Φ63mm
6. Lubrication
Automatic lubrication system, using a closed-loop continuous oiler, ensuring sufficient lubricating oil at each lubrication point; each sliding surface and ball screw are distributed according to the oil circuit, the oil quantity is controlled separately, the circulation lubrication time can be set as needed, and a low oil level control device is provided. The coolant tank uses a split design, making it easy to clean chips and replace coolant.
7. Chip removal A spiral chip conveyor is installed on the outside of the worktable to facilitate the removal of a large amount of chips that fall into the machining area.
