Gear Racks for Laser, Plasma & Waterjet Cutting
Cutting gantries combine long travel with rapid positioning and repeated contour motion. A suitable rack drive has to balance speed, smoothness, backlash control and resistance to the contamination created by the cutting process.
机架驱动器需要做什么
Helical and ground racks are commonly evaluated for high-speed gantries because engagement quality affects running noise and motion smoothness. A robust hardened rack may be more economical on less demanding axes. The machine envelope, controller strategy and pinion/gearbox selection decide which route is appropriate.
该应用应被视为一个完整的系统。这意味着需要将齿条齿系统、小齿轮、变速箱接口、安装底座和润滑方式等因素结合起来进行评估，而不是仅仅假设齿条本身决定性能。
在固定部件之前，先确定机器的运行工况。
这些输入参数决定了报价是仅仅基于几何形状还是反映了驱动器的实际使用方式。
| Gantry span and travel | X/Y travel, rack placement and whether the two sides of the gantry use synchronized drives. |
|---|---|
| Motion | Rapid speed, acceleration and contouring duty. |
| Process environment | Metal dust, slag, abrasive particles, water mist or coolant depending on the cutting process. |
| Positioning | Required contour accuracy, backlash allowance and calibration/compensation method. |
| Maintenance | Lubrication access, guards, wipers and rack cleaning interval. |
此应用中常用的评估产品
以下选项仅供参考，并非自动选择。最终适用性取决于图纸和运行数据。
安装细节决定了精密机架的价值，或使其贬值或得以保留。
Keep process debris out of the tooth mesh. A high-quality rack cannot run accurately if abrasive particles are repeatedly crushed between rack and pinion.
On wide gantries, rack placement and structural stiffness on both sides influence squareness and synchronization.
Lubrication should reach the complete active travel without contaminating the workpiece or process area.
申请咨询时需提交的信息
Send travel, gantry mass, cutting head/process type, maximum rapid speed, acceleration, accuracy target, rack location, gearbox/pinion information and environmental notes. For a twin-drive gantry, include both drive sides in the layout.
如果某些值尚未确定，请将其标记为设计目标。这比插入一个以后难以更改的猜测性规范更有用。
请发送零件的详细信息。
一份有效的报价应从几何形状和运行环境入手。请提供图纸、数量和控制要求；对于齿条驱动轴，请提供行程、速度、加速度、负载以及配套小齿轮或齿轮箱的信息（如有）。
订购： 最小起订量 (MOQ) 根据产品类型和订单金额而定。新客户样品起订量为 1-5 件；混合型号订单总金额在 1500 美元以上时可接受，而 1-2 件的订单单价会更高一些。
时间安排及条款： 标准零件的交货期通常为 10-25 个工作日，定制零件为 20-45 个工作日，项目设备的交货期为 45-120 个工作日。EXW、FOB、CIF 和 DAP 是常用的交货方式；FCA、CFR、CPT、CIP 和 DDP 可以根据具体情况讨论。
