Product Overview
The MK7140A Series CNC Horizontal Spindle And Reciprocating Table Surface Grinder adopts a saddle-movable structure and hydraulic longitudinal drive for the worktable, ensuring stable operation even under maximum loads of up to 450kg. Its grinding wheel spindle features an integral rolling thrust sleeve design, a key innovation that enhances both loading capacity and long-term processing accuracy—critical for industrial applications requiring consistent precision.
Equipped with biaxial linkage control via precision ball screws and servo motors, the machine supports two operating modes: full automatic circulation for high-efficiency mass production and manual control via an electric handwheel for flexible, small-batch processing. An integrated automatic lubrication system reduces component wear, extending the machine’s service life, while a built-in grinding wheel dresser simplifies maintenance and ensures consistent grinding quality. Suitable for machinery manufacturing, auto parts production, mold processing, and precision component fabrication, the MK7140A Series balances productivity, accuracy, and usability.
Key Features
Advanced Structural Design for Stability & Load Capacity
The saddle-movable structure and integral rolling thrust sleeve for the grinding wheel spindle are core to the MK7140A’s performance. This design minimizes vibration during high-speed operation, enabling the machine to handle workpieces with a maximum load of 450kg (MK7140A-3 model) while maintaining processing precision. The worktable, available in sizes ranging from 800×400mm to 1250×400mm, features 18×3 T-slots for secure workpiece clamping—ideal for heavy-duty and large-format grinding tasks.
Biaxial Linkage Servo Control for Precision
Longitudinal and cross movements are controlled by precision ball screws and servo motors (0.75Kw for both vertical and cross axes), ensuring smooth, accurate positioning. The biaxial linkage capability allows for complex processing paths, while the hydraulic-driven worktable offers adjustable speeds from 0 to 25m/min to match different material and processing requirements. Whether in fully automatic circulation mode or manual electric handwheel control, the machine delivers consistent precision for planes, circular arcs, and bevel grooves.
Automatic Lubrication & Grinding Wheel Dressing
The built-in automatic lubrication system delivers oil to key components at regular intervals, reducing friction and wear—lowering maintenance costs and extending the machine’s lifespan. Additionally, the grinding head is equipped with a grinding wheel dresser, and customers can opt for 2-axis servo motor control for the dresser. This upgrade enables automatic compensation during processing, ensuring consistent grinding quality for long production runs and complex workpieces like circular arcs and bevel grooves.
Customizable Control Systems for Versatility
To adapt to diverse production scenarios and operator habits, the MK7140A Series offers customizable control options: choose between a CNC system for advanced programming and complex tasks or a PLC programmable controller with a user-friendly human-machine interface for straightforward operations. This flexibility makes the machine suitable for both high-tech manufacturing facilities and small to medium-sized workshops.
Safety & Ergonomics for Industrial Use
Safety is a top priority in the MK7140A’s design, with integrated safety control mechanisms to prevent operational hazards. The machine’s sleek, ergonomic layout ensures easy access to controls and maintenance points, while its durable construction (net weight up to 4600kg for MK7140A-3) guarantees stability even in harsh industrial environments. Reliable performance, low failure rates, and easy maintenance make it a cost-effective solution for long-term production needs.
