HXQ-625: Structure, Features, and Key Specifications to Consider
HXQ-625 ：结构、特点和主要规格

A stone bridge saw is a heavy-duty cutting machine used to cut large stone slabs into precise sizes for countertops, tiles, wall cladding, stair components, and other architectural applications.
石桥锯是一种重型切割机，用于将大型石板切割成精确尺寸，用于台面、瓷砖、墙面覆层、楼梯部件和其他建筑应用。

The basic design is straightforward but highly effective. Two side rails support a transverse beam, commonly referred to as the bridge. The cutting head, fitted with a diamond saw blade, travels along the bridge, while the bridge itself moves back and forth along the side rails. The blade moves vertically to set the required cutting depth.
其基本设计简洁却高效。两根侧轨支撑着一根横梁，通常称为桥架。装有金刚石锯片的切割头沿桥架移动，而桥架本身则沿侧轨前后移动。锯片垂直移动以设定所需的切割深度。

For stone fabricators, however, choosing the right bridge saw involves much more than looking at blade diameter or motor power. Machine structure, rigidity, table design, cutting range, and control system all have a direct impact on cutting quality and long-term operating costs.
然而，对于石材加工商而言，选择合适的桥式切割机远不止考虑刀片直径或电机功率那么简单。机器结构、刚性、工作台设计、切割范围和控制系统都会直接影响切割质量和长期运营成本。

Monoblock or Split-Type Bridge Saw?
整体式还是分体式桥式锯？

One of the first decisions to make when comparing bridge saws is the machine frame design. Most machines fall into two categories: monoblock and split-type.
比较桥式锯时，首先要考虑的因素之一是机器框架设计。大多数机器可分为两类：整体式和分体式。

Monoblock Bridge Saw  单体桥式锯

A monoblock machine integrates the bridge, side rails, support structure, and worktable into one self-supporting frame. This design is particularly convenient for workshops where installation time and flexibility are important.
一体式机床将桥架、侧轨、支撑结构和工作台集成到一个自支撑框架中。这种设计对于安装时间和灵活性要求较高的车间来说尤为便捷。

The machine can normally be installed on a flat concrete floor without the need for an extensive special foundation. Since the main structure is assembled as one unit, it is also easier to dismantle, relocate, or load into a container when required.
该机器通常可安装在平坦的混凝土地面上，无需复杂的特殊地基。由于其主体结构是一体组装的，因此在需要时也更容易拆卸、搬迁或装入集装箱。

This type of bridge saw is generally a practical choice for small and medium-sized stone fabrication shops, especially for facilities that rent their production space or may need to rearrange the workshop in the future.
这种桥式锯通常是中小型石材加工厂的实用选择，尤其适合租用生产空间或将来可能需要重新布置车间的工厂。

Split-Type Bridge Saw  分体式桥锯

A split-type bridge saw uses separate side supports, with the supporting legs typically fixed to concrete foundations, walls, or specially prepared piers with anchor bolts.
分体式桥式锯采用独立的侧支撑，支撑腿通常用锚栓固定在混凝土基础、墙壁或专门准备的桥墩上。

The main advantage is structural rigidity. Once properly installed, the machine forms a solid connection with the workshop foundation, helping reduce vibration during continuous cutting, especially when processing thick granite, quartzite, and other hard materials.
其主要优势在于结构刚性。正确安装后，机器与车间地基形成牢固连接，有助于减少连续切割过程中的振动，尤其是在加工厚花岗岩、石英岩和其他硬质材料时。

For high-volume production environments with a permanent cutting area, this design can provide a more robust working platform.
对于具有固定切割区域的大批量生产环境，这种设计可以提供更坚固的工作平台。

Why Machine Weight and Structural Rigidity Matter？
为什么机器重量和结构刚度很重要？

When cutting stone, machine stability is not a minor detail. Granite, quartzite, and other hard materials generate considerable cutting resistance, particularly during deep cuts and mitering operations.
切割石材时，机器的稳定性至关重要。花岗岩、石英岩和其他硬质材料会产生相当大的切割阻力，尤其是在进行深切和斜切作业时。

A rigid and properly weighted machine frame helps keep the diamond blade running smoothly. Excessive vibration can affect cutting accuracy, shorten blade life, increase wear on linear guides, and contribute to chipped edges or a rougher finished surface.
坚固且配重合理的机床机架有助于保持金刚石锯片平稳运行。过度振动会影响切割精度，缩短锯片寿命，加剧线性导轨的磨损，并导致切边崩刃或表面粗糙。

Heavy-duty bridge saws therefore tend to use substantial bridge structures and reinforced frames. Some industrial designs use cast-iron bridge assemblies weighing more than 6,200 lb, with overall machine weights exceeding 12,000 lb. The additional mass helps absorb vibration and maintain stability under load.
因此，重型桥式锯通常采用坚固的桥架结构和加固框架。一些工业设计采用重达 6,200 磅以上的铸铁桥架组件，整机重量超过 12,000 磅。额外的质量有助于吸收振动，并在负载下保持稳定性。

Guide rail protection is another important consideration. In a stone-processing environment, slurry, water, and abrasive dust can quickly damage exposed mechanical components. Sealed or oil-bath guide systems are often used to keep contaminants away from the bearing surfaces and extend service life.
导轨保护是另一个重要的考虑因素。在石材加工环境中，泥浆、水和磨蚀性粉尘会迅速损坏裸露的机械部件。通常采用密封或油浴式导轨系统，以防止污染物接触轴承表面，从而延长使用寿命。

Blade Diameter and Main Motor Power
叶片直径和主电机功率

Blade capacity should be selected according to the maximum thickness and type of stone being processed.
刀片容量应根据所加工石材的最大厚度和类型来选择。

A 20-inch blade is commonly used for standard countertop work, particularly when processing slabs in the typical 20–30 mm thickness range. For thicker materials, a larger blade may be required. A 24-inch blade, for example, provides greater cutting depth and is better suited to applications involving thicker stone sections.
20英寸的锯片通常用于标准台面加工，尤其适用于加工厚度在20-30毫米范围内的板材。对于更厚的材料，可能需要更大的锯片。例如，24英寸的锯片可以提供更大的切割深度，更适合加工较厚的石材。

Motor power is equally important. For demanding miter cuts in granite, quartzite, and other hard materials, a main motor rated at around 24 HP (18.5 kW) or above can provide additional torque and help maintain stable spindle speed under load.
电机功率同样重要。对于花岗岩、石英岩和其他硬质材料的高要求斜切，额定功率在 24 马力（18.5 千瓦）或以上的电机可以提供额外的扭矩，并有助于在负载下保持主轴转速稳定。

In practical terms, the right combination of blade diameter, spindle speed, and motor power is often more important than simply choosing the largest motor available.
从实际角度来看，刀片直径、主轴转速和电机功率的正确组合往往比简单地选择最大的电机更重要。

Cutting Range and Z-Axis Travel
切割范围和 Z 轴行程

Before purchasing a bridge saw, check the actual cutting envelope rather than focusing only on the nominal table size.
在购买桥式锯之前，请检查实际切割范围，而不仅仅关注标称工作台尺寸。

The machine should have enough travel to handle the largest slabs commonly used in your workshop. A cutting range of approximately 130 × 130 inches, for example, provides sufficient working space for many full-size engineered quartz and natural stone slabs.
该机器的切割行程应足以处理您车间常用的最大尺寸板材。例如，约 130 × 130 英寸的切割范围，可为许多全尺寸人造石英石和天然石材板材提供足够的加工空间。

Vertical travel also deserves attention. An 18-inch Z-axis stroke gives operators more clearance when working with thick materials, raised workpieces, or special holding fixtures.
垂直行程也值得关注。18 英寸的 Z 轴行程为操作人员在加工厚材料、凸起工件或使用特殊夹具时提供了更大的操作空间。

A well-balanced cutting envelope improves productivity by reducing the need to reposition slabs during production.
均衡的切割范围可以减少生产过程中重新定位板材的需要，从而提高生产效率。

360° Rotating Worktable  360°旋转工作台

A rotating table can make a significant difference in day-to-day production.
旋转工作台可以对日常生产产生重大影响。

Instead of manually moving a heavy slab every time the cutting direction changes, the operator can rotate the workpiece directly on the table. Hydraulic or motorized rotation is particularly useful when multiple cuts are required on the same slab.
操作员无需每次改变切割方向时都手动移动沉重的板材，而是可以直接在工作台上旋转工件。当需要对同一块板材进行多次切割时，液压或电动旋转尤其有用。

Common positioning points include 0°, 45°, 90°, and 135°. Some machines also allow the table to lock at intermediate angles, making it possible to produce octagonal shapes, diagonal cuts, and other special layouts without repeatedly repositioning the material.
常用的定位点包括 0°、45°、90° 和 135°。有些机器还允许工作台锁定在中间角度，从而无需反复重新定位材料即可生产八边形、对角切割和其他特殊布局。

For shops processing a high volume of countertops and architectural stone components, a rotating table can save both handling time and labor.
对于加工大量台面和建筑石材部件的店铺来说，旋转工作台可以节省搬运时间和人力。

Hydraulic Tilting Table Up to 85°
液压倾斜工作台，倾斜角度可达 85°

Loading a full-size stone slab onto a horizontal table can be difficult and potentially dangerous, especially when forklifts, overhead cranes, or vacuum lifters are involved.
将一块完整的石板装载到水平工作台上可能很困难，而且存在潜在危险，尤其是在使用叉车、桥式起重机或真空吸盘时。

An up-tilting table capable of reaching approximately 85° allows operators to load slabs in a more controlled position. Once the slab is positioned, the table can be returned to the cutting position.
可向上倾斜至约 85° 的工作台使操作人员能够以更可控的方式装载板材。板材就位后，工作台即可恢复到切割位置。

This type of system is particularly useful for large-format slabs because it reduces manual handling and makes loading and unloading more manageable.
这种系统对于大尺寸板材尤其有用，因为它减少了人工搬运，使装卸更加容易管理。

Automatic Miter Cutting from 0° to 45°
自动斜切角度范围：0°至45°

Miter cutting is now common in countertop fabrication, particularly for waterfall edges, seamless corners, and other premium edge details.
斜切现在在台面制作中很常见，特别是对于瀑布边、无缝角和其他高级边缘细节。

A bridge saw with an automatic tilting cutting head can generally adjust the blade angle from 0° to 45°. This allows the same machine to perform standard straight cuts as well as angled cuts without requiring a separate cutting setup.
带有自动倾斜切割头的桥式锯通常可以将刀片角度从 0° 调整到 45°。这使得同一台机器既可以进行标准直线切割，也可以进行角度切割，而无需单独的切割装置。

For hard materials, smooth and controlled miter movement is important. Stable blade positioning and hydraulic or servo-controlled movement can help maintain a consistent angle and reduce unwanted tool marks along the cut edge.
对于硬质材料，平稳可控的斜切运动至关重要。稳定的刀片定位以及液压或伺服控制的运动有助于保持一致的角度，并减少切割边缘上不必要的刀痕。

Electrical Requirements  电气要求

A bridge saw is a relatively high-power piece of stone-processing equipment, so the workshop electrical supply should be checked before installation.
桥式切割机是功率相对较高的石材加工设备，因此在安装前应检查车间的电源供应情况。

Most industrial machines require three-phase power. Depending on the destination market and electrical infrastructure, the control cabinet may be configured for systems such as 220 V, 380 V, or 480 V three-phase power.
大多数工业机械需要三相电源。根据目标市场和电力基础设施的不同，控制柜可以配置为适用于 220V、380V 或 480V 等三相电源系统。

The final voltage and frequency should always be confirmed before production and shipping. Electrical components, motor specifications, protection devices, and the control system should all be matched to the local grid conditions.
最终电压和频率必须在生产和发货前确认。电气元件、电机规格、保护装置和控制系统都应与当地电网条件相匹配。

Workshop Space and Foundation
工作坊空间和基金会

The space required for a bridge saw is larger than the machine dimensions shown in a product catalog.
桥式锯所需的空间比产品目录中显示的机器尺寸要大。

When planning the installation, allow additional room for slab loading, operator access, maintenance, electrical cabinets, and movement around the machine. A complete working area may require an operating envelope of roughly 25 ft wide × 17 ft deep × 12 ft high, depending on the machine configuration and material-handling method.
规划安装时，应预留足够的空间，用于承载混凝土板、操作人员通道、维护、电气柜以及机器周围的活动。根据机器配置和物料搬运方式，完整的作业区域可能需要大约 25 英尺宽 × 17 英尺深 × 12 英尺高的操作空间。

For machines using anchor bolts or fixed support legs, the condition of the concrete floor is also important. A foundation thickness of around 250 mm is often considered when planning heavy-duty installations, although the actual requirement should be confirmed according to the machine's structural design and anchor system.
对于采用地脚螺栓或固定支撑腿的机器，混凝土地面的状况也至关重要。在规划重型设备安装时，通常会考虑约 250 毫米的基础厚度，但实际要求应根据机器的结构设计和锚固系统来确定。

CNC Bridge Saw vs. PLC Bridge Saw
CNC 桥式锯与 PLC 桥式锯的比较

The difference between PLC and CNC bridge saws is mainly related to control functions, programming capability, and the type of work the machine is intended to handle.
PLC 桥式锯和 CNC 桥式锯的区别主要在于控制功能、编程能力以及机器要处理的工作类型。

A PLC-controlled bridge saw is typically designed for straightforward production work. Operators can enter cutting dimensions through a touchscreen interface and perform automatic straight cuts, as well as standard miter cuts.
PLC 控制的桥式锯通常设计用于简单的生产作业。操作人员可以通过触摸屏界面输入切割尺寸，并执行自动直线切割以及标准斜切。

A 5-axis CNC bridge saw goes much further. It can work with CAD/CAM software and is designed for more complicated operations, including shaped cutting, interpolation, drilling, profiling, and certain three-dimensional stone-processing applications.
五轴数控桥式切割机的功能远不止于此。它可以与 CAD/CAM 软件配合使用，专为更复杂的操作而设计，包括异形切割、插补、钻孔、轮廓加工以及某些三维石材加工应用。

For workshops focused mainly on countertop fabrication and regular straight or miter cuts, a PLC bridge saw can be a practical and cost-effective solution. For more complex fabrication work, a 5-axis CNC machine offers considerably greater flexibility.
对于主要从事台面加工和常规直线或斜切的工坊来说，PLC 桥式锯是一种实用且经济的解决方案。而对于更复杂的加工工作，五轴数控机床则能提供更大的灵活性。

Can a Heavy-Duty Bridge Saw Cut Sintered Stone?
重型桥式锯可以切割烧结石吗？

Yes, but the machine configuration matters.
是的，但机器配置也很重要。

Sintered stone is highly dense and can be demanding on the cutting system. Stable spindle rotation, sufficient motor torque, appropriate blade selection, and accurate speed control all contribute to a better cutting result.
烧结石材密度极高，对切割系统要求很高。稳定的主轴旋转、足够的电机扭矩、合适的刀片选择以及精确的速度控制，都是获得更佳切割效果的关键。

A motor in the 24 HP class can provide useful power reserves for demanding applications, helping the spindle maintain more consistent speed when cutting hard materials.
24 马力级别的电机可以为要求苛刻的应用提供有用的动力储备，帮助主轴在切割硬质材料时保持更稳定的速度。

However, motor power alone does not determine cutting performance. Blade quality, spindle accuracy, feed speed, cooling water, machine rigidity, and operator settings all have a significant influence on the final result.
然而，电机功率本身并不能决定切割性能。刀片质量、主轴精度、进给速度、冷却水、机器刚性以及操作人员的设置都会对最终结果产生显著影响。

What Should You Look for When Choosing a Stone Bridge Saw?
选择石桥锯时应该注意哪些方面？

For most stone fabrication businesses, the best bridge saw is not necessarily the machine with the biggest blade or the highest motor power. The more important question is whether the machine matches the materials, slab sizes, production volume, and cutting processes of the workshop.
对于大多数石材加工企业而言，最好的桥式切割机未必是刀片最大或电机功率最高的机器。更重要的问题是，这台机器是否与车间的材料、板材尺寸、产量和切割工艺相匹配。

Before making a purchase, it is worth checking the following:
购买前，建议检查以下内容：

• Maximum blade diameter and cutting depth
  最大刀片直径和切割深度

• Main motor power and spindle configuration
  主电机功率和主轴配置

• X, Y, and Z-axis travel
  X、Y 和 Z 轴行程

• Machine frame rigidity and overall weight
  机器框架刚性和整体重量

• Rotating and tilting table functions
  旋转和倾斜工作台功能

• Miter cutting range  斜切范围

  售后服务和备件供应

A well-designed stone bridge saw should provide accurate cutting, stable operation, easy material handling, and reliable performance over years of production.
设计精良的石材桥锯应具备切割精准、运行稳定、物料搬运方便、经久耐用等优点。

For professional stone fabricators, these factors usually have a greater influence on real operating costs and productivity than the machine's purchase price alone.
对于专业的石材加工商而言，这些因素通常比机器的购买价格本身对实际运营成本和生产率的影响更大。
