MADE-TO-ORDER PCD REAMERS
Project-Engineered PCD Reamers
We design and manufacture made-to-order PCD reamers for cylinder blocks, cylinder heads, valve bodies and other complex precision-bore projects. Each tool is developed as part of a complete application solution—not selected from stock.
How We Develop a Reamer for Your Component
A PCD reamer is not a stock item. Each project moves from component review and tool concept to approved design, manufacture and inspection.
To Get Started:Share the component drawing, bore tolerance, machine interface and current machining issue.
- Complete Project Design
- High Bore Accuracy
- Low Tool Runout
- Application Engineering Support

PCD Reamer Manufacturer
Sundi designs and manufactures PCD reamers for our clients around the world and in several industries for precision machining of non-ferrous metals and non-metallic material to achieve the parts requirement finish and accuracy.
When processing copper, zinc, aluminum, and other non-ferrous metals, the processing material is easy to adhere to the cutting tool, resulting in the working process is hard to go on. In such a situation, because of the lower friction coefficient and affinity with non-ferrous metals, Our PCD reamer can efficiently prevent the metal from bonding with the tool, and PCD tool cutting edge deformation is small, the surface of the workpiece is excellent.
- High Accuracy and Efficiency
- High-speed Cutting Feed Rate
- Excellent Roughness
- Fewer Process Steps Low cycle time
- Maximum tool life
- Re-grinding to reduce the cost

How We Made the PCD Reamers
Step 1 · Analysis & Design
Define the reamer design around the requirements of your application.
- Application
- Discuss the machining task and understand the customer's requirements.
- Quality targets
- Establish the required accuracy, surface roughness and tool life.
- Tool design
- Develop a PCD reamer design for the intended application.
Step 2 · Rough Machining
Prepare the tool body and chip grooves before assembling the cutting blades.
- Tool body
- Form the body through CNC turning, milling and cylindrical grinding.
- Chip grooves
- Machine the flutes using 5-axis CNC equipment.
- Heat treatment
- Include heat treatment in the body manufacturing process.
Step 3 · Laser Cutting
Cut the PCD disc into blade shapes ready for the next manufacturing step.
- Layout
- Calculate and arrange the blade profiles in the cutting software.
- PCD blades
- Laser-cut the disc into the required individual blades.
- Consistency
- Maintain consistent blade dimensions for the next operation.
Step 4 · Vacuum Brazing
Join the PCD blades to the tool body in a vacuum brazing furnace.
- Blade positioning
- Place the PCD blades in the brazing grooves with silver solder.
- Furnace cycle
- Heat the assembly at 800°C for 20 minutes.
- Brazed joint
- Melt the solder to bond the blades securely to the tool body.
Step 5 · Wire Cutting
Produce complex PCD cutting profiles using 5-axis Vollmer wire cutting.
- Profile machining
- Use 5-axis wire cutting to create complicated reamer geometries.
- Cutting finish
- Cold-oil processing supports a surface finish of up to Ra 0.4.
- Equipment
- Three Vollmer machines support this manufacturing operation.
Step 6 · Cylindrical Grinding
Refine the cutting edge when the application requires a smoother hole finish.
- Surface finish
- Grind the cutting edge to improve the finish of the PCD tool.
- Edge preparation
- Reduce edge sharpness where needed to limit hole-wall vibration.
- Dimensional accuracy
- Control accuracy to within 0.002 mm after cylindrical grinding.
Step 7 · Inspection
Check the completed cutting geometry before handing the tool to quality control.
- Geometry checks
- Use Zoller equipment to inspect diameters, angles and arcs.
- Programmed inspection
- Check the tool geometry against the inspection program before QC.
- Dynamic balance
- Test applicable HSK and BT shank tools for rotational concentricity within 0.002 mm.
Step 8 · Surface Treatment
Apply the requested surface treatment and identification markings.
- Surface treatment
- Provide sandblasting or oxidation treatment to suit customer requirements.
- Appearance & protection
- Improve the surface appearance and help prevent rust.
- Tool identification
- Add laser-marked model information as required.

Do You Have PCD Reamers in Stock
We are very sorry that all reamers are custom-made according to the customer’s requirements. So we don’t have any in stock.
How Long Can We Receive Our Tools After Placing the Order
The delivery time depends on the complexity of the tool, the size of the tool size, and the purchasing quantity. Big data shows that for the straight handle reamer with less than 4 teeth, we usually take about 7-15 days to finish them. 15-25 days for HSK handle BT handle reamers and 20-35 days for flange handle reamers.
How Do We Ensure That Our Ordering Reamers Are Working Well
Dear customers, We will 100% inspect all dimensions of every reamer before shipment, and generate detailed inspection reports. We will deliver to you together with the tools.
How Will We Receive Our Tools
