The EROWA quick-positioning clamp system is broadly divided into four major categories based on its application: EDM positioning system, CNC positioning system, zero-point positioning system, and automation system. Among these, the EDM and CNC positioning systems are relatively similar in design, but differ in application: EDM systems are primarily used on spindle-mounted equipment (e.g., electrical discharge machining), while CNC systems are mainly applied to worktable-mounted machining centers, with distinct processing methods requiring different positioning systems. Both EDM and CNC systems generally consist of the following components:
1.Chucks: The most fundamental component of the system. For EDM equipment, square-head or round-head chucks (e.g., D100edm pneumatic chuck, 80 square pneumatic chuck, D100edm manual chuck) can be mounted on the spindle. For CNC machining, single-head or multi-head chucks (e.g., D100cnc chuck, 2-head CNC chuck, compact chuck) are used for worktable-mounted machining centers.
2.Clamp heads (electrode holders): Selected based on the shape and size of the processed workpiece, available in square, U-slot, and flat types. For automation applications, they are further divided into chip-positioned and non-chip-positioned variants. Proper selection of electrode holders significantly reduces processing defects.
3.Positioning plates and locking pins: These are the core components ensuring the precision of the EROWA system. Through line contact with the chuck’s positioning rhombus and combined with the locking pins, they generate flexible deformation to achieve a positioning accuracy of ±0.002mm. Positioning plates vary by load capacity (e.g., 50, 90, G-type, 50×90), while locking pins include pneumatic and standard types.
4.Inspection components: Used for calibration and centering of chucks during initial setup for both EDM and CNC processing. Components include 30 cylindrical zero-position(zero-position reference base), 50×50 zero-position reference base, 100×60 zero-position reference base, centering rods, and centering balls, simplifying the centering process.
5.Wire EDM fixtures: Such as V-shaped bottom wire EDM fixtures, 3-axis micro-adjustable wire EDM fixtures, fixed-type and adjustable-type wire EDM fixtures, designed to enhance processing efficiency and accuracy for WEDM.
6.Video inspection devices: Video inspection devices with EROWA, 3R, multi-functional, and magnetic interfaces to enable real-time detection of processing issues.
In summary, while the EDM and CNC positioning systems may seem complex, their design philosophy centers on standardization, enabling rapid tool changeover for high-efficiency and high-precision production.
The zero-point positioning system ensures consistent zero-point alignment when transferring workpieces between workstations, processes, or machines, eliminating the need for repeated table alignment. This significantly reduces downtime, maintains processing continuity, improves machine utilization, and enhances overall productivity. Common examples include MTS zero-point chucks.
Automation fixtures, as the name suggests, are used in automated production lines. They receive signals from computer systems to direct robotic arms to perform specified actions, serving as clamping, supporting, and transporting tools. Examples include robotic hands, grippers, mechanical arms, and grip handles.
