Key Features
Premium Build Quality
Machine main body crafted from HT250 cast iron, twice-tempered to reduce brittleness and enhance structural stability.
Worktable guideway with plastic lamination minimizes friction, reducing wear and improving machining accuracy.
Dual-Variant Design (Normal & Heavy-Duty)
Normal type: Round grinding head, 400×40×127mm grinding wheel, suitable for standard grinding tasks (0.03~0.05mm per pass).
Heavy-duty type: Square grinding head with ball screw (no extra lubrication needed), 400×50×203mm grinding wheel, and reinforced spindle for deep grinding (0.03~0.2mm per pass).
High-Precision Grinding Performance
Achieves surface roughness of Ra:0.63μm and machining accuracy of 0.008mm/300mm, meeting strict industrial standards.
Vertical handwheel feed (0.01mm per grad; 1mm per revolution) enables precise depth control.
Efficient Hydraulic & Motor Systems
Independent hydraulic oil station (optional) ensures smooth longitudinal and transverse movement.
Total motor power of 11kw (7.5kw spindle motor + 3kw oil pump motor) delivers strong grinding force.
Complete Accessory Package
Includes coolant mechanism, magnetic chuck (400×1000mm), grinding wheel set, balance tools, and maintenance wrenches—ready for immediate use.

FAQ
What is the difference between normal and heavy-duty models?
Heavy-duty models feature a square grinding head with ball screw (no extra lubrication), larger grinding wheel (400×50×203mm), reinforced spindle, and higher grinding capacity (0.030.2mm per pass) vs. normal models (0.030.05mm per pass).
Does the quotation include an independent hydraulic station?
Standard quotes (FOB Shanghai: 30000USD for normal type; 31200USD for heavy-duty type) do not include an independent hydraulic station. It can be added as an optional accessory—contact us for a customized quote.
What is the delivery time?
Delivery takes 30 days from the date of advance payment (30% TT). The balance is due via TT against inspection in China.
Can the machine be customized for larger worktables?
Yes. We offer custom worktable sizes (e.g., 400×1250mm, 400×2000mm, 400×3000mm). Let us know your requirements for a tailored solution.
