Key Features

Thermal Stress Stabilization: Rough-machined castings/plates undergo furnace thermal cycling prior to finish grinding to eliminate post-machining geometric drift.

Datum Reference Edge: Precision-ground A/B reference edges (Ra 0.8 um) aligned to machine Y/X axes within 0.008 mm.

Zero-Point & Fluid Integration: Custom counterbores, pilot diameters, and retention bolt patterns matched to Erowa, Lang, or Schunk risers, including internal hydraulic/pneumatic rotary feed-through passages.

Chip Clearance Channels: Chamfered perimeter relief and optimized coolant drain-through pockets engineered per machining setup.

Applications

5-Axis Trunnion Retrofit: Transition plates mounting modular zero-point receivers onto rotary/tilt tables (Haas, Mazak, DMG Mori).

High-Mix Pallet Tooling: Interchangeable subplates for quick-change HMC pallet pools (400 mm to 800 mm standard footprints).

Heavy Roughing Subplates: T-slot or grid combination bases absorbing high lateral cutting forces in structural steel/titanium milling.

Customization Capabilities

Geometry: Round, rectangular, polygon, or multi-tier riser profiles.

Surface Treatment: Gas nitriding (HV 550 - 650 case depth 0.2 mm), black oxide, or hard anodizing (aluminum).

Marking: Laser-etched grid coordinate labels (A-Z, 1-99) for quick part-loading reference.

Engineering Review: DFM feedback on wall thickness, core-out weight reduction, and clamping reaction zones within 24 hours of RFQ.

Quality Control Protocol

Incoming: Hardness testing (Brinell/Rockwell) on cast iron blanks; ultrasonic flaw detection on structural steel slabs.

In-Process: CMM intermediate probe check on grid pitch prior to final finish grind.

Final Audit: Full-surface flatness laser scan report + dimensional CMM inspection report shipped with every lot.

Instrumentation Traceability: Zeiss Contura CMM calibrated annually to ISO 10360-2.

Manufacturing Assets & Certifications

Machining Assets: 5-axis gantry milling centers (table up to 2000 mm), high-precision horizontal boring mills, surface grinders (table length 1500 mm).

Facility Scope: Temperature-controlled final inspection room (20 deg.C +- 1 deg.C).

Certification: ISO 9001:2015 (Scope: Precision machining of metal tooling components and fixture subassemblies).

Packaging & Shipping

Corrosion Protection: Sprayed VCI (Volatile Corrosion Inhibitor) oil coating + sealed heavy-duty VCI bag (>12 um).

Mechanical Protection: Edge-protector strips on ground reference faces; bolted immobilization brackets inside crating.

Crating & Handling: ISPM-15 compliant fumigated plywood crates featuring affixed stillage/pallet gross weight and center-of-gravity (CoG) tags for container crane loading.

Commercial Terms: EXW / FOB (Major China/regional ports) / DDP-capable subject to destination forwarder audit.

Frequently Asked Questions

Q: What is your standard lead time for a custom grid base (500x500 mm with H7 dowels)?

A: 15 - 18 working days from drawing freeze and material arrival. Rush service (10 days) available subject to thermal annealing queue.

Q: Do you accept customer-supplied castings?

A: Yes, provided rough stock allowance (+2 to +3 mm per surface) is confirmed via pre-machining stock inspection.

Q: What CAD formats are preferred?

A: STEP (.stp/.step), Parasolid (.x_t), or native SolidWorks/Inventor backed by dimensioned PDF drawing for GD&T critical callouts.
