TSK2120A×2000mmCNC Deep Hole Drilling And Boring Machine

Core Advantages

The machine bed is built with resin‑sand high‑strength cast iron in split construction, connected by high‑strength bolts and positioned with taper pins. All castings go through normalization and two‑time aging treatment to eliminate internal casting stress. It is equipped with double rectangular precision‑ground quenched hard guide rails. Internal V‑shaped inclined reinforcing ribs greatly improve anti‑deformation and vibration‑damping capacity.

Precision quenched helical rack is mounted inside for stable feeding transmission. Oil‑return grooves with oil shields are cast around bed frame for automatic cutting‑oil recycling. The headstock is fixed on left side of bed to drive workpiece rotation. It features manual three‑speed gear shifting with stepless speed within each gear. Servo spindle motor transfers power by belt and gear‑box assembly. Gears are precision ground and high‑frequency quenched for high strength and impact resistance. Independent external circulating lubrication oil tank is fitted with low‑liquid‑level alarm. Local button panel on headstock provides spindle jog, feed jog and emergency‑stop for convenient on‑site operation. The oil pressure head undertakes workpiece clamping, tool guiding and cutting‑oil supply. Servo motor drives its axial travel, which can run under torque mode or position mode to tighten or release workpieces of different lengths. High‑rigidity rotary bearings and maintainable rotary sealing parts are built‑in.

Drill‑bar supporting sleeve, guide sleeve and cone‑disk positioning assembly are installed on front end. Push‑pull oil shield prevents coolant splashing and guides cutting‑oil flow back to oil tank. The drill box is mounted on feeding carriage to drive cutting‑tool rotation. It has manual three‑speed gear shifting with inner‑range stepless speed, driven by 37KW servo spindle motor.

Spindle front‑end sleeve holds drill bars. Chip‑removal hopper on rear side smoothly discharges cutting chips. Internal gears are precision ground and high‑frequency quenched. Independent external circulating lubrication oil tank comes with low‑liquid‑level alarm function. High‑rigidity integrated drill‑bar support rest firmly holds drill bar during cutting process and absorbs cutting impact and vibration.

It is equipped with automatic hanging‑return mechanism. When feeding carriage moves backward, the support rest can be automatically pulled back to original position. Workpiece clamping solution combines headstock manual three‑jaw chuck and oil‑pressure‑head cone‑disk for two‑end positioning and locking. Two sets of V‑shape workpiece carriers provide pre‑positioning support before clamping. V‑frame height can be manually adjusted via T‑shaped screw. After formal clamping, workpiece will separate from carriers to avoid rotation interference. Coolant system includes heavy‑duty floor‑standing fully‑welded oil tank, cooling pump and chip collection box. No underground pit is required for installation. Retractable protective covers prevent debris from dropping into oil tank. Pressure, flow, liquid‑level and oil‑temperature parameters can be digitally displayed on operation station. Max coolant pressure reaches 2.5MPa, max flow rate reaches 400L per minute and oil‑tank volume is 3900L.

Different functional units adopt targeted lubrication arrangement. Feeding‑carriage sliding surfaces get timing‑quantitative lubrication from automatic lubrication station with low‑liquid‑level alarm. Headstock and drill‑box gears and bearings are lubricated by respective independent circulating oil tanks with liquid‑level monitoring. Oil‑pressure‑head carriage and drill‑bar‑support‑rest carriage rely on manual lubrication pump. DELTA‑PLC control system governs two servo axes. Z‑axis realizes longitudinal feed motion of drill box through reducer and rack‑pinion mechanism. X‑axis controls axial travel of oil pressure head for workpiece tightening and releasing. Operation button groups are arranged both on feeding carriage and headstock for flexible operation. Electric cabinet is equipped with cabinet air‑conditioner to guarantee stable running of electrical components.

Ideal Workpieces & Pain Points Solved

Suitable workpieces include hydraulic cylinder barrel blanks and various long tubular parts which require deep‑hole drilling and pre‑boring processes.

Common production difficulties this machine solves. Extra investment for separate drilling machine and boring machine increases workshop cost and occupied floor space. Drill‑bar vibration leads to hole skewness and poor straightness in deep‑hole rough‑machining. Chip‑removal difficulty occurs in BTA deep‑hole drilling. Contaminated coolant shortens tool service life. Time‑consuming workpiece alignment and clamping for long tubular blanks.
