商品介紹
Product Overview
The MM7120A and MM7120B models are high-precision horizontal spindle rectangular table surface grinding machines designed for grinding flat surfaces using the periphery of the grinding wheel. They can also grind slots and flange sides using the wheel's end face, achieving high precision and surface finish. These machines are ideal for grinding various precision parts and molds, suitable for use in machining workshops, maintenance shops, and tool rooms.

Features
- Cross Slide Structure: The machine adopts a cross slide design, minimizing thermal deformation and ensuring stable precision.
- Hydraulic System: The table's longitudinal movement is driven by a variable vane pump within a closed hydraulic system, ensuring smooth motion, low noise, and minimal oil temperature rise.
- Cross Feed Mechanism: The cross slide uses roller guides, with feed driven by an AC variable frequency motor for stepless speed adjustment, allowing fine intermittent and continuous feeds.
- Spindle Bearings: The spindle employs small-hole throttling hydrostatic bearings with high rotational accuracy, achieving superior surface finishes.
- External Oil Tank: The MM7120B model features an external oil tank for easy maintenance and replacement of the hydraulic system.
