Polycrystalline diamond (PCD) cutting tools are engineered for demanding applications where tool life, cutting performance, and dimensional accuracy are critical. Producing and servicing these tools requires specialized equipment capable of accurately processing the extremely hard PCD cutting edge.
PCD tool erosion machinery provides a precise, automated solution for the production and servicing of PCD cutting tools. HMT Machine Tools now offers three advanced ABM PCD erosion machines designed for applications ranging from PCD-tipped circular saw blades to hoggers, router bits, helical cutters, profile knives, moulders, and other PCD tooling.
The new HMT PCD erosion lineup includes the CNC-E800, SPARQ-DUO, and SPARQ, providing manufacturers and tool service centers with multiple options for bringing PCD erosion in-house, increasing production capacity, or upgrading existing PCD tool manufacturing and servicing equipment.
What Is PCD Tool Erosion?
PCD tool erosion is a machining process used to precisely shape and finish the polycrystalline diamond cutting edges of PCD cutting tools. CNC-controlled erosion technology allows manufacturers and service centers to produce accurate cutting geometries while maintaining the precision required for high-performance diamond tooling.
Unlike conventional cutting tool grinding applications, PCD requires specialized processing because of the exceptional hardness and wear resistance of polycrystalline diamond.
Modern CNC PCD erosion machines combine automated axis control, specialized erosion generators, tool positioning, measurement technology, and application-specific programming to produce consistent and repeatable cutting-edge geometries.
PCD erosion technology can be used for both new PCD tool production and the servicing of existing PCD cutting tools.
What Types of Cutting Tools Can Be Processed with PCD Erosion Machinery?
Depending on the machine configuration, PCD erosion equipment can be used to manufacture and service a wide variety of diamond cutting tools, including PCD-tipped circular saw blades, PCD saw teeth, hoggers, helical cutters, router bits, profile knives, moulders, profile tools, and other PCD cutting tools.
This makes CNC erosion technology applicable to both dedicated PCD circular saw blade manufacturing operations and tool manufacturers or service centers working with multiple PCD tool geometries.
Why Bring PCD Tool Erosion In-House?
For companies currently outsourcing PCD tool processing, adding an in-house PCD erosion machine can create greater control over production schedules, tool quality, turnaround times, and capacity.
In-house PCD erosion capabilities can also allow a cutting tool manufacturer or service center to expand into new tooling applications rather than relying entirely on outside suppliers for PCD processing. And entering the PCD erosion market may be more affordable than expected.
HMT's ABM lineup provides an accessible path for companies looking to start or expand PCD tool production and servicing capabilities without assuming that advanced CNC erosion technology is out of reach.
Current estimated delivery for all three models is just 8–12 weeks, allowing companies to add or upgrade PCD erosion capacity relatively quickly.
PCD Tool Erosion Machinery from HMT
HMT Machine Tools offers three ABM CNC erosion solutions, each designed around different PCD tooling applications:
The ABM CNC-E800 is a 6-axis CNC PCD erosion machine designed specifically for the precision production and servicing of PCD-tipped circular saw blades.
The machine accommodates circular saw blades from 100–800 mm (4–32") in diameter and combines CNC automation with precise servo-controlled positioning for accurate and repeatable PCD erosion.
Its application-specific design makes the CNC-E800 particularly well suited for circular saw manufacturers and saw blade service centers looking to establish, automate, or expand PCD saw blade erosion capabilities.
Key capabilities include 6-axis CNC control, automated blade positioning, flexible erosion programming, pneumatic blade clamping, and integrated safety systems.
The ABM SPARQ-DUO is an 8-axis CNC dual-side PCD erosion machine designed for the production and servicing of PCD-tipped circular saw blades from 150–800 mm (6–32") in diameter.
Its dual-side configuration allows the erosion process to be completed in a single setup, helping improve automation and production efficiency.
The SPARQ-DUO also provides intelligent indexing for group-tooth and variable-pitch circular saw blades, automatic tooth-pitch calculation, dedicated programming for newly replaced teeth, and software designed for PCD circular saw blade production.
For manufacturers or service centers focused on high-productivity PCD circular saw blade erosion, the SPARQ-DUO provides an advanced automated solution.
The ABM SPARQ is a versatile 5-axis CNC PCD erosion machine designed for the production and servicing of multiple types of PCD cutting tools.
With a maximum tool diameter of 400 mm (16") and maximum erosion length of 150 mm (6"), the SPARQ can process applications including circular saws, hoggers, helical cutters, router bits, profile knives, moulders, and other PCD profile tooling.
An integrated Renishaw measuring system allows the erosion process to be completed in a single setup, while ABM's digital erosion generator, absolute servo control, and rigid composite monoblock machine construction support accurate and repeatable PCD processing.
For tool manufacturers and sharpening/service operations that need flexibility across different PCD cutting tool geometries, the SPARQ provides a versatile CNC erosion platform.
Which PCD Erosion Machine Is Right for Your Operation?
The right PCD erosion machine primarily depends on the type of cutting tools being produced or serviced and the level of automation required.
For operations primarily processing PCD circular saw blades, the CNC-E800 and SPARQ-DUO provide dedicated circular saw erosion solutions.
For manufacturers and service centers processing a broader variety of PCD cutting tools, the SPARQ provides additional application flexibility for complex tooling such as router bits, hoggers, helical cutters, profile knives, and moulders.
Add PCD Erosion Capabilities to Your Operation
Whether you're entering the PCD tooling market, bringing outsourced PCD work in-house, increasing production capacity, or upgrading an existing erosion process, HMT can help determine the appropriate CNC erosion solution for your application.
With affordable PCD erosion options and current estimated delivery of 8–12 weeks, now is an opportunity to evaluate how PCD erosion technology could fit into your operation.

Frequently Asked Questions About PCD Tool Erosion
What is a PCD erosion machine?
A PCD erosion machine is specialized equipment used to precisely process the polycrystalline diamond cutting edges of PCD cutting tools. Modern machines use CNC-controlled positioning and erosion technology to produce accurate and repeatable cutting-tool geometries.
What does PCD stand for?
PCD stands for polycrystalline diamond. PCD is an extremely hard, wear-resistant cutting material commonly used in tooling applications requiring long tool life and consistent cutting performance.
Can PCD circular saw blades be processed with CNC erosion?
Yes. Dedicated PCD circular saw blade erosion machines, including the ABM CNC-E800 and SPARQ-DUO, are designed for the production and servicing of PCD-tipped circular saw blades.
Can the same erosion machine process different types of PCD tools?
Some machines can. The ABM SPARQ is designed for multiple PCD cutting tool applications, including circular saws, hoggers, helical cutters, router bits, profile knives, moulders, and other PCD tooling.
What is dual-side PCD erosion?
Dual-side PCD erosion allows a machine to process both sides of the PCD saw tooth within a single setup. The ABM SPARQ-DUO is specifically designed around this approach for PCD circular saw blade production and servicing.
