Why Is Quartzite So Hard to Cut?

Quartzite ranks 7 on the Mohs hardness scale — that’s harder than granite and almost as tough as engineered stone. Its dense, interlocking quartz crystals make it extremely durable, but also very abrasive. Standard cutting tools wear out quickly or fail altogether when used on quartzite.

That’s why using a specialized quartzite diamond blade is essential.


Key Features of Diamond Saw Blades for Quartzite Cutting

The ideal diamond blade for cutting quartzite needs to have:

1. High-Quality Diamond Segments
Premium-grade diamonds ensure smoother cuts and longer blade life. At SANG, we use industrial-grade diamonds optimized for quartzite’s high density and abrasiveness.

2. Laser-Welded Segments
Laser welding strengthens the bond between the blade core and the cutting segments, reducing the chance of segment loss under high stress or temperature.

How can CNC Punch Laser Combined Machine be applied to more factories?

2025-11-10

1. Accurately convey core values and address the "pain points" of factories

When promoting, it is necessary to explain the direct economic benefits it can bring in a language that factory owners and production managers can understand.

"One machine replaces multiple lines", saving space and initial investment

Promotional point: There is no need to purchase separate punch presses and laser machines, reducing the floor space occupied by the equipment, power configuration and basic investment.

Tell the factory owner: "You only need one investment to establish a complete sheet metal processing unit, which is particularly suitable for new factories with limited factory space or those planning new production lines."

Minimize processes to the extreme to enhance efficiency and delivery time

The promotional point: It eliminates the process of transferring, re-clamping and secondary positioning between the punch press and the laser machine. The sheet is clamped once to complete all processing.

Tell the production manager: "The delivery time of your products can be shortened by 30% to 50%." Because there is no intermediate flow or waiting time, it is particularly suitable for small-batch and multi-variety urgent orders.

Break through design limitations and empower high value-added products

Promotional points: The mold-free nature of lasers enables them to easily cut any complex shapes and inner cavities. The high efficiency of stamping allows for rapid processing of louvers, bumps, threaded holes, etc.

Tell R&D/designers: "You can freely design complex products without being restricted by molds." Laser cutting creates elegant curves, and stamping instantly forms functional structures, making your products more unique and competitive in the market.

Reduce reliance on highly skilled operators

Promotional point: One device, one set of programming software (usually integrating stamping and laser functions), and one operator can complete the entire process from programming to production, reducing management and labor costs.

 

Second, innovate business models and lower application thresholds

The high initial investment is the main reason why many small and medium-sized factories are deterred. It needs to be resolved through a flexible business model.

Financial leasing and installment payments

Cooperate with financial institutions to offer flexible installment or lease plans for factories, converting huge capital expenditures into manageable monthly operating costs.

"Trade-in" program

Encourage factories with old single-function punch presses or laser machines to upgrade their equipment, use the old equipment to offset part of the purchase price, and accelerate equipment iteration.

Establish demonstration factories and experience centers

Establish demonstration sites in industrial zones to allow potential customers to witness the efficient operation of the equipment with their own eyes. They can also bring their own samples for on-site sampling and convince them with actual results.

Cooperate with the sheet metal industry chain

Cooperate with sheet material suppliers, spray painting factories, etc. to provide their customers with packaged solutions of "equipment + materials + post-treatment", increasing their appeal.

 

Third, promote technological popularization and enhance usability to remove usage obstacles

Make the factory feel that it is "user-friendly, daring to use and easy to use".

Develop more intelligent and integrated software

The software should be capable of automatically identifying the features of the drawings, intelligently recommending whether to use stamping or laser processing (for example, small round holes and holes of the same batch should be stamped, and complex contours should be processed with laser), and automatically generating the optimal processing path to reduce programming difficulty.

Provide strong technical training and support

We offer a full range of training from programming, operation to maintenance. Establish a rapid response local service team to provide 7x24-hour technical support and solve the factory's worries.

Modular and upgradable design

Provide the basic model and reserve the upgrade interface. Factories can first purchase configurations that meet current needs. In the future, based on business development, they can add automated modules such as automatic loading and unloading, sorting and palletizing to reduce initial investment.

 

Fourth, accurately identify the target industry and customer group

Not all factories are suitable for immediate purchase. It is necessary to find the right breakthrough point.

Core target customers

Sheet metal processing service center: They are the most ideal target users for composite machines because their business is to undertake various scattered and high-demand sheet metal parts.

Equipment manufacturers specializing in multi-variety and small-batch production: such as those in industries like chassis and cabinets, elevators, food machinery, medical devices, environmental protection equipment, and intelligent warehousing equipment.

Innovative enterprises in a period of rapid growth: They have high requirements for production flexibility and product iteration speed, and are willing to invest in advanced equipment to build core advantages.

Potential market

Replacement market: The target is those factories that are still using old-fashioned single-function equipment and have encountered production efficiency bottlenecks. Use the high efficiency of multifunctional machines to convince them to carry out "production upgrades".

Are cast iron round frying pans safe to use?

2025-10-31

Yes, cast iron round frying skillet pans are safe to use and are actually known for being extremely durable and versatile. They’re great for high-heat cooking, searing, frying, and even baking. However, there are a few things to keep in mind to ensure they stay in good condition and are safe:

  1. Proper Seasoning: Cast iron pans need to be properly seasoned to maintain their non-stick surface and prevent rust. A well-seasoned pan can handle high temperatures and adds flavor to food. If your pan starts to rust or the seasoning wears off, you’ll need to reseason it.

  2. Handling with Care: Cast iron can get extremely hot, so always use an oven mitt or pot holder when handling the pan to avoid burns.

  3. Avoiding Abrasive Cleaning: After use, avoid harsh scrubbing or soaking the pan, as it can damage the seasoning. A little hot water and a stiff brush are usually enough. If you do need to clean it more thoroughly, you can reapply some oil to help maintain the seasoning.

  4. Preheating: Cast iron pans should be preheated slowly, especially if they are cold. Rapid temperature changes can cause them to crack or warp.

  5. Storing Properly: After use, make sure the pan is completely dry before storing it to avoid rusting. You can also apply a thin layer of oil to prevent moisture from getting in.

 

So, if you take care of it, a cast iron round frying pan is not only safe to use, but it can last for generations!

How to connect materials to the screw jack

2025-10-31

We all know that worm gear screw jacks have two kinds of operation modes: translating screw and travelling nut. Regardless of the operation modes, worm gear screw lifts require a stable, level mounting surface for secure installation.

The housing of a translating screw jack is fixed to the mounting surface, with travel space above and below the mounting surface. The top end of the lead screw connects to the material for up and down movement. Screw end can be designed with various connection options, including flanges, straight rods, threads, fork pins, pinholes, ball joints, making them suitable for installation in various equipment conditions.

worm gear screw jacks


Travelling nut screw jack use a nut connected to the material for up and down movement. There is travel space above the screw actuator's mounting surface, while the lead screw rotates in place. A nut attached to the lead screw connects to the material for up and down movement. The screw end can be either straight rod or threaded. To prevent the screw rod  from shaking during lifting, a bearing seat is required to secure the screw head.

Problems in using manual screw lifts

2025-10-31

The handwheel driven worm gear screw jack is simple and convenient, making it a good choice for applications where power supply installation is difficult. Worm gear screw lifts are self-locking and are very convenient for fine-tuning equipment where speed and precision are not critical and no electrical connections are required, simply cranking a handwheel or handle can move tons of material.

Customers often ask whether a lead screw jack ‘s handwheel will struggle when driving heavy loads. The answer is yes. While the worm gear drive structure of a screw lift can reduce speed and increase torque, allowing it to move large objects with minimal force, human power is limited. While increasing the lever arm can minimize output torque, there’s no better solution.

When choosing a handwheel-driven screw lift, especially for customers with high travel requirements, they often complain about slow lifting speeds. Worm gear lead screw jacks can be self-locking, but transmission efficiency is low. To increase speed, the lead screw can be made into a double or triple lead. Multiple leads can increase the lead screw’s lifting speed, but they lack self-locking properties. For equipment that requires load retention, a brake device must be considered.


Lead screw jacks can be driven by various motors, connected via matching flanges or couplings. For equipment with limited access to a power source, a handwheel or crank can also be used. Manual lead screw jacks have certain drawbacks when used with large travels and heavy loads. Therefore, manual lead screw jacks are more suitable for equipment that requires less speed and fine-tuning.

Why Bevel Gear Screw Jacks Have Higher Transmission Efficiency than Worm Gear Screw Jacks?

2025-10-31

worm gear screw jacks vs bevel gear screw jacks



The difference in transmission efficiency between bevel gear screw jacks and worm gear screw jacks mainly comes from their distinct meshing methods and friction characteristics. A worm gear mechanism works similarly to a screw and nut, relying heavily on line contact and sliding friction to transmit motion. Because of the high relative sliding speed, significant energy is lost as frictional heat. As a result, the mechanical efficiency is typically only 30%–50%, and even under precise machining and good lubrication conditions, it is difficult to exceed 60%. In contrast, bevel gears operate much like conventional gear systems. Their meshing involves point or near-line contact, with rolling friction as the dominant mode. Since relative sliding is minimal, the efficiency can reach 90%–98%, with far less energy loss compared to worm gears.


Transmission ratio also plays an important role. Worm gear screw jacks can achieve high gear ratios (such as 1:20 to 1:100), but as the ratio increases, the lead angle of the worm decreases, causing more sliding friction and further lowering efficiency. Bevel gears, however, typically operate within a smaller ratio range (about 1:1 to 1:5), which allows them to maintain high efficiency while also keeping tooth contact stresses at a favorable level.

Another key factor is self-locking capability. Worm gear screw jacks exhibit self-locking because the friction angle is greater than the lead angle, preventing the load from back-driving the worm. This feature eliminates the need for additional braking devices when holding a load, but it also means that energy cannot be transmitted back through the system, reducing efficiency. Bevel gear screw jacks, on the other hand, allow for efficient bidirectional transmission. They lack self-locking capability and usually require a motor brake or mechanical brake to hold the load, but they achieve much higher energy transfer efficiency.

From the perspective of heat management and service life, worm gear screw jacks generate substantial heat during operation due to sliding friction, requiring proper lubrication and cooling. Without this, wear accelerates and service life decreases. Bevel gear systems, by comparison, produce far less heat, demand simpler lubrication, and deliver stable efficiency over long-term operation, resulting in a longer lifespan.

In practice, worm gear screw jacks are better suited for low-speed, intermittent applications where load holding is important, such as stage lifts or valve actuation. Bevel gear screw jacks, by contrast, are ideal for frequent operation, higher-speed transmission, and applications where energy efficiency is critical, such as automated production lines and continuous-duty equipment.



Why the speed in the linkage system of a worm gear lead screw lifter cannot be too fast?

2025-10-31

worm gear screw jacks system

Why the speed in the linkage system of a worm gear lead screw jack cannot be too fast?There are some reasons that should be considered:


1. Safety Considerations

   The screw jack handles heavy loads, and excessive speed may cause loss of control of the equipment or load, increasing the risk of accidents—especially during stopping or emergency braking when large inertial forces occur.

2. Mechanical Structure Limitations
   The worm gear screw jack actuator mainly uses worm gear transmission, which has a strong self-locking feature but relatively low efficiency. Excessive speed can cause excessive wear or damage to the worm gear teeth and lead screw surface.

3. Heat Generation and Dissipation Issues
   High-speed operation increases friction and generates a lot of heat. The worm gear screw lifterassembly has limited heat dissipation capability, which can lead to lubricant failure and overheating of components, shortening equipment lifespan.

4. Reduced Positioning Accuracy
   Machine screw jack actuator are often used where precise positioning is required. Too high speed can cause instability or vibration, adversely affecting work precision and product quality.

5. Limitations of the Drive Motor and Control System
   Excessive speed may exceed the design parameters of the motor and control system, causing overloads, frequent protective shutdowns, or control malfunctions.


Therefore, to ensure safe operation, extend service life, and maintain positioning accuracy, the speed of the linkage system in worm gear lead screw lifters is usually designed to be low and stable.
