Description
🔹 Product Overview
The BOSCH 1070070767-203 is an SMNC_1/B/.5/4/8 control board used in Bosch industrial CNC/NC control environments. The board is commonly listed together with an SC512KB SRAM Memory Card, making this configuration particularly relevant for maintenance and replacement of legacy Bosch CNC controller systems.
The SMNC board and its associated memory card provide a board-level spare-parts solution for older Bosch numerical-control equipment. Maintaining the complete board-and-memory configuration can be important when replacing a controller card where machine-specific data or configuration information is stored on removable memory.
The exact memory-card identification should be checked on the physical unit before ordering. Different listings associate the 1070070767-203 board with memory-card references including 19000195, 32000195 and 725-0003-01.

⚙️ Key Features
- Bosch SMNC_1/B/.5/4/8 control-board configuration.
- Part number 1070070767-203 for precise spare-parts identification.
- Commonly supplied with an SC512KB SRAM memory card.
- Designed for legacy Bosch CNC/NC controller maintenance.
- Board-and-memory combination is useful when maintaining an existing machine configuration.
- Suitable for machine-tool repair, controller replacement and refurbishment.

🏭 CNC & Industrial Control Applications
The SMNC_1/B/.5/4/8 configuration is associated with Bosch industrial CNC/NC control equipment. It is particularly relevant to legacy machine tools where the controller architecture relies on dedicated processor/control boards and removable memory.
Potential maintenance applications include:
- Bosch CNC machine tools
- NC-controlled production machinery
- Legacy numerical-control cabinets
- Industrial machine automation
- CNC controller refurbishment
- Board-level controller repair
- Long-term spare-parts inventory
For older machines, replacing the correct controller board can be preferable to replacing an entire CNC control assembly, provided the hardware and stored machine data are compatible.
💾 Memory Card & Configuration
The memory card is an important part of this product configuration.
Listings for 1070070767-203 show the board paired with an SC512KB SRAM Memory Card. Associated references found in industrial spare-parts listings include 19000195, 32000195, and 725-0003-01.
Because the memory card can contain machine-specific information, do not automatically transfer or overwrite it without confirming the machine configuration.
Before replacement:
- Record the original memory-card identification.
- Photograph the memory-card position and orientation.
- Record any machine-specific data or configuration references.
- Confirm the replacement board revision.
- Verify the memory card supplied with the replacement.
- Preserve the original board and memory card until commissioning is complete.
🔌 System Integration
When replacing the SMNC board, treat the board and memory card as a matched maintenance assembly.
Recommended procedure:
- Record 1070070767-203 and SMNC_1/B/.5/4/8.
- Record all secondary PCB markings and revision information.
- Verify the memory-card part number.
- Back up available CNC parameters and machine data.
- Disconnect system power before removing the existing board.
- Inspect the card rack and board connector.
- Install the replacement board carefully.
- Verify memory-card seating and orientation.
- Power up under controlled conditions.
- Check CNC/NC diagnostics before running machine functions.
🛠️ Installation & Maintenance
Use ESD protection when handling the board and SRAM card. Do not touch exposed PCB contacts unnecessarily.
Before installation, inspect the board for:
- Bent connector pins
- Corrosion
- Contamination
- Damaged components
- Cracked solder joints
- Mechanical damage
- Loose memory-card connections
For storage, keep the board and SRAM card in antistatic packaging in a clean, dry environment. Label the complete assembly with the Bosch part number and memory-card identification to prevent mixing different revisions.
🔍 Troubleshooting
The CNC controller does not recognize the replacement board:
Check board seating, rack contacts, connector condition and the exact 1070070767-203 identification.
The controller starts but machine data is incorrect:
Check the SRAM memory card and confirm that the correct machine-specific memory configuration is being used.
The memory card is not detected:
Inspect card orientation, contacts and compatibility. Compare its identification with the original card before replacing or rewriting data.
The replacement board has a different suffix:
Do not assume 1070070767-201, -202, -203, -204 and -205 are interchangeable. The exact hardware revision should be matched to the machine configuration.
The machine produces CNC/NC alarms after replacement:
Review the controller diagnostics, configuration data, memory card and connected modules before changing machine parameters.
✅ First-Operation Checklist
Before returning the machine to production:
- Confirm BOSCH 1070070767-203.
- Confirm SMNC_1/B/.5/4/8 marking.
- Check PCB revision and secondary identification.
- Confirm the supplied SRAM memory-card marking.
- Compare the replacement assembly with the original.
- Inspect rack and connector contacts.
- Verify CNC/NC configuration backups.
- Power up and check controller diagnostics.
- Test machine functions in manual mode.
- Perform a controlled automatic-cycle test.
❓ FAQ

📦 Spare-Parts & Lifecycle Planning
For legacy Bosch CNC systems, the controller board and its memory card should be managed as a critical spare-parts assembly when failure can stop production.
Recommended practices include:
- ABC Classification: classify critical SMNC controller boards as high-priority spares.
- Buffer Stock: keep one tested replacement for production-critical machines.
- Memory Protection: maintain verified backups of machine parameters and configuration data.
- Incoming Inspection: check board number, revision, connectors and memory-card identification.
- Functional Testing: test the complete board-and-memory configuration whenever possible.
- Revision Control: maintain a record of installed and spare board revisions.
- Last-Time-Buy Planning: consider additional stock for aging Bosch CNC systems with limited replacement availability.
