What Advantages Does a Laser Tool Cutting Machine Have Over Conventional Tool Machines? Key Questions Beginners Must Understand

In the field of processing ultra‑hard tools such as PCD and CBN, conventional grinding processes have long been the mainstream. However, in the past two years, laser tool cutting machines have been rapidly gaining ground – more and more tool manufacturers are switching to laser solutions. Beginners may ask: What exactly makes laser tool cutting machines superior? Is it worth replacing old equipment?

Today, let’s answer a few key questions that beginners care about most, without beating around the bush.

Question 1: Is the edge quality from laser cutting better than from grinding?

This is the most fundamental question. Conventional grinding uses a grinding wheel to “abrade” away excess material, which tends to produce tiny chips or burrs on the cutting edge. Moreover, the grinding force and thermal stress can damage the bond strength between the PCD layer and the substrate.

Laser processing is non‑contact – the focused beam “vaporizes” the material. There is no mechanical force, and the heat‑affected zone is controlled within a very small range. A good laser tool cutting machine can produce edges with almost invisible chipping. For example, the NOVICK CL Series measures edge chipping at the micron level – to the naked eye it looks like a smooth, bright line. In actual use, such edges give PCD tools longer life and lighter cutting action. Many customers report: “With grinding, our tools quickly developed chips; after switching to laser, tool life increased significantly.”

Question 2: Is laser processing efficient? Does it trade speed for quality?

Quite the opposite – laser is both fast and precise. Conventional grinding of a PCD tool may require multiple clampings, changing different grinding wheels, complex programming, and long auxiliary times. A laser tool cutting machine can complete the entire process from roughing to finishing in a single operation.

Take the NOVICK CL Series as an example. It has a built‑in process library for eight common tool types. Select the tool type, and the system automatically matches the laser parameters and machining path. Even better: a historical machining database automatically saves the parameters of every machined tool. The next time you need the same tool, you can start machining within three minutes. No need for a master craftsman to repeatedly tune parameters – even a novice can get started quickly.

If you add an optional robotic automatic tool loading/unloading system, a tool change takes less than half a minute. In batch production, one operator can attend several machines during the day, while at night the machines run unattended – you collect finished parts the next morning. Such efficiency is hard to match with conventional grinding.

Question 3: Is five‑axis simultaneous control just a gimmick? Isn’t ordinary three‑axis enough?

For simple straight‑shank PCD end mills, three axes might be barely adequate. But the trend in cutting tools is toward complexity and customization – for example, automotive engine head tools often have angled features, contours, and helical grooves; woodworking form tools come in all shapes. A three‑axis machine can only cut vertically and horizontally; it cannot handle beveled surfaces.

The value of five‑axis simultaneous control is that the laser head can tilt and rotate to approach the material at the optimal angle, machining all surfaces in a single setup. The NOVICK CL Series uses direct‑drive motors on the A and B axes with absolute rotary encoders, eliminating the backlash of conventional mechanical transmission, achieving high and long‑lasting rotational accuracy. As one user put it: “No matter how odd the tool shape, put it on and it cuts – no repeated clamping and alignment.”

Question 4: Is the machine difficult to operate? Do you need to hire a “master craftsman”?

Conventional grinding places high demands on operator experience – selecting the right wheel, adjusting speed, controlling feed rate. One small mistake can burn the tool or cause edge chipping. Laser tool cutting machines turn “experience” into “menus.”

The NOVICK CL Series features a 31.5‑inch 4K vertical screen. The upper part displays a high‑definition camera view of the cutting process in real time; the lower part is the control interface. Every technical term on the screen comes with dynamic hints, so you won’t be lost when entering parameters. Tool processing starts with one button – from detection to machining, it‘s fully automatic. Many users say: “Our old tool sharpening master retired. Now a young newcomer, following the on‑screen prompts, can work independently in two or three days.” For manufacturing enterprises struggling with recruitment, this is a very practical advantage.

Question 5: Is the maintenance cost of laser equipment high?

You don’t need to worry about this. The CL Series uses a fiber laser. Compared to older CO₂ lasers, fiber lasers have long life, are maintenance‑free, and have high electro‑optical conversion efficiency. The overall machine design also includes a constant‑temperature bed system, using an oil chiller to dissipate heat from key components, preventing thermal expansion from causing accuracy drift, and also extending equipment life. Daily consumables are mainly auxiliary gas (compressed air) and a small amount of lubricating grease – there are no frequently replaced consumables.

Summary: When should you seriously consider adopting a laser tool cutting machine?

If your products involve ultra‑hard materials such as PCD or CBN; if the tools you machine are complex in shape and require frequent changeovers; if you want to reduce dependence on “master craftsmen” and increase batch production efficiency – then a laser tool cutting machine is already an unavoidable choice.

The NOVICK CL Series currently has two main models for different application scenarios:

·CL2‑400: Designed specifically for woodworking PCD tools, and can also handle some automotive tools. It features a self‑developed five‑axis simultaneous control system, standard 100W fiber laser, X/Y/Z travel 300×400×300 mm, wide A/B axis rotation range, maximum tool weight 30 kg, maximum tool size ø280×300 mm. Optional robotic automatic tool loading/unloading. Equipped with a 31.5‑inch 4K vertical screen, video‑integrated interface, eight‑tool preset process library, and historical machining database. Optional on‑line inspection probe. Suitable for woodworking form tools, milling cutters, and batch PCD tool production.

·CL2 Pro‑400: A high‑end model for automotive PCD tool processing. Core parameters are essentially the same as the CL2‑400, but the tool interface uses a more universal BT50 adjustable hydraulic tool holder, which can also accept BT40 and HSK A63 tool holders – offering greater versatility. Suitable for machining complex‑contour, high‑precision PCD tools in the automotive field. Also equipped with five‑axis simultaneous control, 4K smart screen, process library, and historical data memory.

Both models can be optionally equipped with a high‑power dust collector to keep the machining environment clean. NOVICK has service locations nationwide, a 24‑hour after‑sales hotline, and provides timely support from installation and commissioning to operation training and remote diagnostics. At the 14th China CNC Machine Tool Exhibition (CCMTS 2026), the NOVICK CL2‑400 laser tool cutting machine won the Spring Swallow Award – a recognition of the company’s independent innovation capability and of technological progress in domestic high‑end tool processing equipment.

In practical applications, the CL Series has helped many tool manufacturers significantly improve edge quality and processing efficiency. We recommend that you bring your most difficult‑to‑machine tools to a NOVICK technical center for an on‑site trial cut. Examine the edge chipping, time the tool change, and ask the operator how easy it is to learn. The answer will be clear.
